JCI: Investments in sustainability have rebounded to pre-pandemic levels
CORK, Ireland, 12 April 2022: Johnson Controls (JCI) announced findings from its 15th annual Energy Efficiency Indicator Survey, which revealed that 62% of organizations surveyed expect to increase investments in energy efficiency, renewable energy or smart building technology in 2022, indicating a return to pre-pandemic levels.
JCI said the latest report by the United Nations Intergovernmental Panel on Climate Change advised that global scale transformation is urgently needed to combat climate change; however, its Energy Efficiency Indicator Survey found that organizations are still facing challenges to accelerate their sustainability efforts in key areas. Almost two-thirds of survey respondents say they struggle to scale sustainability initiatives across buildings, geographies or business units.
“In the face of the multiple and continuous shock waves of the last two years, it is very encouraging to see that building owners and operators are driving forward the kinds of investments that deliver the resilience needed to grow their business and attract and retain the best talent,” said Katie McGinty, Vice President & Chief Sustainability and External Relations Officer, JCI.
“Whether it is the damage delivered by climate-charged destructive natural events, or the health threat of the pandemic, or now, the stark demonstration of the insecurity of world energy supplies, it is clear that taking action to cut energy demand while decarbonizing and cleaning the air are core strategies for companies, governments and institutions to not only survive but to thrive.
Our innovative technologies in heat pumps and our OpenBlue digital platform, plus our Net Zero as a Service partnership offering, are exactly the right tools at the right time for leaders determined to stay well ahead of challenges and deliver new opportunities for their business or organization.”
JCI said the survey revealed that planned investment in energy generation or storage has grown significantly over five years, likely in response to the global focus on decarbonization, and as part of that effort, electrification.
More than a third of respondents plan to replace fossil fuel heating equipment with heat pump technology in the next year, which is seven per cent more than what was implemented in the year prior, the company said. Notably, thermal energy storage jumped from 27% to 42% in the last five years, the company said. More than half of respondents implemented electric energy storage in the past year, the company added.
JCI said the survey also found that the United States and Europe still lead the way in every metric of green building planning. The United States had the most respondents who had already achieved green building certification and expect to have a net-zero-energy or carbon building in the next 10 years, JCI said.
Europe had the most respondents planning to attain green building certifications and the most respondents who have established public energy or carbon-reduction goals, with United Kingdom leading with 46% established goals, JCI added.
Compared to its global counterparts, significantly more respondents in the United States plan to implement measures, such as building controls improvements, onsite renewable energy and energy management process, such as ISO 50001, JCI said. Of the countries surveyed, the United Kingdom, France and Japan have the most respondents who expect to increase investment in energy efficiency, renewable energy or smart building technology over the next year, the company said. Still, to reach global sustainability and environmental goals, the world must work collectively to plan for a more energy efficient future and make investments today for the generations to come, it added.
Although global-scale transformation is necessary to course-correct on climate change, organisations are facing barriers to pursuing sustainability initiatives, JCI said. Almost half of the respondents surveyed say their top barrier to pursue energy and building technology improvements is either a lack of funding to pay for improvements (25%) or uncertainty in their return-on-investment (23%), the company said.
Additionally, more than half of respondents pointed to a lack of technology as one of the hindrances to scaling sustainability efforts, JCI said.
The pandemic has also prompted organizations to rethink their technology investment decision-making, JCI said. Protecting the health and safety of building occupants during the coronavirus pandemic was the second most significant driver of investments globally, it said. Additionally, 65% of respondents performed an indoor air quality assessment last year, it added.
Respondents to the survey also said improving occupant health and wellness overall and improving life safety and security were important decision-making factors, JCI pointed out. Over the next 12 months, almost 60% of organizations plan to invest in fire and life safety system and security system improvements to their buildings, it said. Long term, more than two-thirds of organizations believe data analytics and cybersecurity will have an extremely or very significant impact on the implementation of smart buildings over the next five years, it added.
The survey revealed that actionable policies are also important for progressing energy efficiency goals, JCI said, adding that 85% and 72% of respondents, respectively, reported that performance benchmarking, certifications and performance standards for energy codes are critical to improving energy efficiency efforts.
JCI said its Energy Efficiency Indicator Survey collected responses from 1,000 participants globally between November and December 2021.

Poppy introduces IT-based IAQ solution at EXPO 2020 seminar
DUBAI, UAE, 21 March 2022: Canada-headquartered Poppy, which calls itself the world’s first biosafety intelligence company, introduced its IT-based IAQ devices to the MENA region during a seminar at the Canada Pavilion, at the World Expo in Dubai.
Opening the seminar, Nader Arafat, Strategic Advisor, MENA Region, Poppy, spoke of the pandemic ushering in a mindset shift towards Indoor Air Quality (IAQ). Speaking after him, Mohammed Bin Dasmal, Managing Director, Bin Dasmal Group, called Poppy’s devices as focusing on IAQ as well as on energy savings.
Sam Molyneux, Co-Founder & Co-CEO, Poppy, elaborated on Bin Dasmal’s pithy description during his presentation. Saying that the world needs to protect itself from future pandemics, he said it is important to understand indoor safety and the cost of enhancing safety. Making clean air in a cost-effective way is a global priority, he added.
Referring to the high-profile Guangzhou restaurant, the site of the precipitous outbreak of COVID-19, in the period starting from January 26 to February 10, 2020, Molyneux highlighted how a small air conditioning system was able to propagate the virus and raised ventilation concerns. In view of that, he said, in some senses, ventilation is the last stand against COVID-19. Poppy systems, he said, help in making ventilation decisions, including demand-control ventilation, as a means to achieving IAQ goals without compromising on energy efficiency targets.
The devices, Molyneux said, available on subscription basis, detect and identify over 1,000+ pathogens, including SARS-CoV-2 and its variants, using genomic sequencing and molecular assays. They allow the company to collect data related to human breath, which in turn, allow understanding on how human breath moves, which he said is crucial, considering everyone is constantly breathing out particles that contain viruses.
The data, and the understanding of the data, he said, enable the company to validate how air conditioning systems are performing and, broadly speaking, provide insights and a direction for action to protect indoor spaces and occupants.
Molyneux said the company has deployed Poppy systems in 50 sites across North America and Europe, including factories, financial institutions, schools and entertainment venues. He gave the example of Poppy systems at work at the largest investment bank in Manhattan, in New York City, where the company is able to monitor the air quality in the trading floor, among other zones of the building and identify if any zones have high transmission issues that need to be looked into.
He also gave the example of the Four Seasons Center for the Performing Arts, in Toronto, Canada, where Poppy systems are at work monitoring and providing recommendations, so that the Center is able to run its operas again. “We are able to recommend increasing the ventilation rates in hotspots, which is a localised approach, and reducing ventilation rates globally,” Molyneux said. “So, we are able to achieve energy savings.”
‘One for the books’: Organisers of HVACR mega show, AHR Expo, say
WESTPORT, Connecticut, 10 February 2022: The AHR Expo returned last week to Vegas after a forced hiatus in 2021, International Exposition Company (IEC), the organisers of the show, said through a news release.
After two years of uncertainty and a longing to reunite the industry, the event represented an eagerness to return to business, drawing 30,678 attendees, IEC said. What’s more, the success of the show signals a reignited energy for all things HVACR and the community’s readiness to take on the challenges and opportunities ahead with renewed optimism, IEC said. “It was impossible to miss the energy in the halls this year,” said Mark Stevens, Show Manager.
“There have been some heavy ups and downs across the industry in recent years, and we, as a community, needed to feel the inspiration that happens when we gather together under one roof. The 2022 AHR Expo surpassed any expectation – our exhibitors, attendees, associations, speakers and everyone involved made this event one of the most special we’ve ever hosted. If you were there, the camaraderie was hard to miss. This industry is strong, and we are back on track to tackle the challenges before us.”
According to IEC, attendees were eager to be back in the booths experiencing new products and methods that support their work in the field. It was evident from every corner of the show floor that this industry is bursting with prospects, IEC added. “My main reason for attending the AHR Expo is the whole experience,” said Arizona tradesman and first-time attendee, Brendan Bowie.
“You get to meet all the people who make the things that we buy and look up to and use every day. It is a lot of the vendors that we spend money with, because they make superior products. I talked to presidents and CEOs of companies that I buy products from every day, every week, every month. Instagram stories are not going to tell what AHR is, it’s the whole experience. Going to AHR matters, because you have to see what’s going on out there. I had the opportunity to see so much new. We’re trapped in vans every day on the job, you need to see what’s out there.”
According to IEC, a total of 1,573 exhibitors spread out over 443,769 square feet in the Central and North halls, packing the floor with an explosion of innovation and new products. Given the time apart, there was plenty to take in, as exhibitors launched new technology, products and ideas that came to life since we last gathered in Orlando, IEC said. “We and our [manufacturer] member companies that exhibited were very pleased with the quality of the Las Vegas Expo,” said Stephen Yurek, President & CEO, AHRI.
“We heard comment after comment about the quality and number of attendees and how grateful everyone was to get back together with their industry colleagues and customers. We are grateful to our [manufacturer] members for moving ahead with what turned out to be a really good show, and we look forward to seeing some of them in Guadalajara in September and more of them next year in Atlanta.”
According to IEC, inside the exhibitor booths, this year, company reps and attendees were busy catching up on lost time. The challenges in the supply chain and other COVID-related delays have opened the door for new ways of thinking about partnerships, IEC said. Emerson, one of the exhibitors, endorsed the organizer’s statement.
“Emerson has always valued the customer engagement opportunities provided by the AHR Expo and the forum to showcase our sustainable solutions that are helping to reduce global impact while improving comfort, efficiency, performance and food safety in the HVACR industry,” said John Schneider, President, HVACR Technologies Americas, Emerson.
“After last year’s pause, the Expo provided a much-needed, in-person touchpoint, and we were thrilled to have our valued customers join us in celebrating our Copeland brand’s 100-year milestone during our pre-show customer event. This year, we also sponsored the Podcast Pavilion, which was a great opportunity for us to align with industry influencers as their role in this industry continues to expand.
Ultimately, all our businesses and brands experienced a great turnout, and we are looking forward to even more attendance in 2023.” Added Sarah Beyerlein, Everwell Parts: “It does not matter where you come from or where in the industry you’re involved in, the AHR Expo is the most remarkable yearly event where we all share our passion and expertise in the HVAC industry. It cannot be missed out.”
Innovation sets the course
On Monday, January 31, the show celebrated the 2022 Innovation Award Winners with a private reception. Members from each winning company were invited to share food and drink and be among industry cohorts also being recognized as leaders in shaping the future of HVACR, IEC said. The 2022 AHR Expo Innovation Award Product of the Year Award, IEC said, went to Danfoss, for their Danfoss Turbocor VTCA400 Compressor, a winner in the Cooling category.

AprilAire, Airthings announce IAQ-related strategic partnership at AHR Expo
LAS VEGAS, Nevada, 31 January 2022: AprilAire, which supplies Indoor Air Quality (IAQ) solutions for the home, announced a strategic partnership with Airthings, a global technology company that produces IAQ monitors for radon and other dangerous airborne contaminants that impact overall health and wellness.
Making the announcement through a joint Press release, the two companies said the partnership is rooted in addressing a common issue for homeowners everywhere: People spend more than 90% of their time indoors, but most are unaware of their home’s IAQ – and when they identify a problem, they typically do not have the knowledge and expertise to remedy the situation effectively.
The new AprilAire and Airthings partnership, the companies said, is a ground-breaking, full circle integration that combines detection, education and mitigation to offer contractors an intelligent air quality solution tailored specifically to their customer’s lifestyle and living environment.
Airthings’ monitors help people learn about their IAQ and identify problems utilizing the brand’s line of smart air quality sensors to intelligently monitor conditions in the home, the two companies said. AprilAire helps solve air quality problems with the AprilAire Healthy Air System and the complete line of whole-home healthy air solutions and nationwide network of top HVAC experts trained to install them, the companies added.
In partnership, the brands will now provide consumers with a one-stop shop, combining the best in radon and air quality monitoring with the best solutions to manage air purity, humidity, fresh air supply, radon mitigation and temperature, the two companies claimed.
“We are proud to partner with Airthings, a company whose purpose so closely aligns with our own of making homes healthy,” said Dale Philippi, President and CEO, AprilAire. “Together, we will increase awareness of the impact the air we breathe in our homes has on our health and wellbeing and the availability of effective professional solutions to deliver healthy air. Working with Airthings, our network of healthy air experts will be better able to tailor solutions to address homeowner concerns.”
Airthings will integrate its flagship air quality monitor, View Plus, as a core component of the AprilAire partnership solution, the two companies said. View Plus, launched in 2021, is a comprehensive and advanced consumer air quality monitor on the market, tracking seven air quality components, including particulate matter, CO2 and radon, the companies claimed. AprilAire recently added Radon Mitigation Systems to its healthy air solutions portfolio to control radon, the leading cause of lung cancer for non-smokers, the companies said.
Equipped with hub functionality, View Plus will enable HVAC professionals to remotely monitor air quality in the homes they service while also providing full air quality visibility to the homeowners themselves, the companies said. When problems arise, the professional receives automatic notifications and can take immediate mitigation actions, the companies said. The newly formed alliance between AprilAire and Airthings will help consumers access information on their air quality with more clarity, and expert consultation than ever before, enabling them to make informed decisions, the companies added.
Oyvind Birkenes, CEO, Airthings, said: “Our new partnership with AprilAire helps consumers navigate complex decisions in a convenient way. Indoor air quality can be a real threat to our health and well-being, which is why proactive monitoring is essential. However, when problems arise, the next steps can seem daunting. By teaming up with AprilAire, our hope is that when people encounter indoor air quality issues, they’ll turn to us to evaluate the situation, diagnose the problem, and develop recommendations and solutions to mitigate the situation if necessary – providing peace of mind to people everywhere.”

New global study supports healthy buildings as a critical public health strategy
PALM BEACH GARDENS, Florida, 9 September 2021: For the first time on a global scale, new research has found that healthy buildings with enhanced ventilation can improve the cognitive function and health of occupants, suggesting that ventilation and filtration are pre-eminent healthy building strategies, Carrier Global Corporation said through a Press release. Primary support for the study came from Carrier.
The study, COGfx Study 3: Global Buildings, was led by researchers from the Harvard T.H. Chan School of Public Health as part of the renowned COGfx Study series, which examines the impact of indoor air quality on how people think and feel, Carrier said.
The latest study supports the prior studies’ lab and US findings and further supports that indoor air quality is not only good for people’s health and safety, it’s good for the bottom line, as well – through increased productivity, fewer sick days and better cognitive function, Carrier said.
“As more people move toward returning to offices, schools and recreational activities, the health, safety and intelligence of indoor environments have come into greater focus,” said Dave Gitlin, Chairman & CEO, Carrier. “The COGfx Study continues to demonstrate that proper ventilation and filtration of indoor environments plays an important role across the globe in fostering a proactive health strategy. At Carrier, we are focused on delivering innovative solutions and services that positively impact the health, productivity and cognitive performance of occupants of all buildings.”
The COGfx Study 3: Global Buildings examined the impact of indoor air quality on the cognitive function of office workers across six countries – China, India, Mexico, Thailand, the United Kingdom and the United States. The research found that cognitive function declines as the levels of fine particulate matter (PM2.5) and carbon dioxide (CO2) increase, Carrier said, referencing the study. Higher CO2 can be an indicator of poor ventilation in buildings, the company added.
Importantly, mechanical ventilation, such as an HVAC system with efficient filtration, can help to protect building occupants from the negative cognitive effects of PM2.5 and CO2, Carrier said. In addition to acute impacts on cognitive function, reducing exposure to PM2.5 is associated with many other health benefits, including reductions in cardiovascular disease, asthma attacks and premature death.
While the research focused on office employees in commercial buildings, the takeaways are applicable for all indoor environments, Carrier said, adding that as a company it offers numerous products and services that optimize indoor air quality, including a suite of advanced solutions through Carrier’s Healthy Buildings Program that serves key verticals including, healthcare, hospitality, education, retail and marine.
This latest research builds on previous COGfx studies that demonstrated better thinking and better health can be found inside healthier buildings. The first study found cognitive function test scores doubled when study participants were in simulated green building environments with enhanced ventilation as opposed to conventional building environments. The COGfx Study 2 examined real-world building environments in the United Stayes and showed that employees in green-certified buildings showed 26% higher cognitive function test scores and 30% fewer sick building symptoms versus buildings that were not green-certified.
According to Carrier, the COGfx Study 3 can be found at www.theCOGfxStudy.com.
‘Clean up indoor air, or else expect COVID to surge’
TROY, New York, 21 August 2021: An air quality engineer warned that the COVID-19 pandemic won’t end until Americans clean up the indoor air.
“With variants on the rise, all the talk this summer has been about vaccines,” said Jeremy McDonald, Vice President at New York-based firm, Guth DeConzo Consulting. “Now we’re hearing about masks again, which feels like a step back for most of us. But when it comes to preventing the spread of airborne viruses, like COVID-19, we also have to improve the quality of the air in our indoor spaces. As the seasons change, it seems like we’re going back to old, tired strategies that haven’t gotten us out of this mess. It’s time to listen to the engineers: It’s all about the air.”
Mc Donald on July 26 published an essay, titled ‘Moving Beyond COVID-19: It’s Time to Look at the Air We Breathe’, in which he argued that President Joe Biden’s ‘American Jobs Plan’ must include improvements to the indoor air quality (IAQ) infrastructure, if Americans are to finally beat the COVID-19 pandemic and improve defenses against future pandemics and common day-to-day air quality maladies. Toward the end of July, COVID-19 cases began to surge in parts of the United States, and the Centers for Disease Control and Prevention revised its mask guidance to once again recommend that Americans wear masks indoors, even if vaccinated.
McDonald encouraged improvements to ventilation and the use of high-performance air filters and other air purification technologies, where appropriate. Buildings that have deferred maintenance and investment in modern HVAC may require more complicated and expensive solutions, he said.
“Although some buildings may require an expensive investment, we need to weigh this against the cost of our health and well-being,” McDonald wrote in his essay. “Certainly, when considering our health, fixing ‘sick’ buildings is a much better choice than fixing ‘sick’ people.”
Yet, McDonald said, there are plenty of low-cost or no-cost solutions that can drastically improve IAQ, such as cracking a window, which reduces the intensity and quantity of virus particles and their ability to spread to more people, using air purification technologies, and simply ensuring that buildings meet the spirit of building code requirements for minimal fresh air for buildings.
Saying that there is a historical precedent for this common sense strategy, McDonald noted in his essay: “In response to the Pandemic of 1918, when more than 20,000 New Yorkers died, ventilation was seen as one of the key attributes to protect residents from the devastation of the pandemic. Back then, New York City officials dictated that building heating systems were to be designed and sized to operate with all the windows open, since it was recognized that ventilation was key to purge the virus from indoor spaces. If it worked 100 years ago, it will work today.”
One of the main challenges in getting people to pay more attention to poor indoor air quality is that the problem is invisible, an issue McDonald commented on in an original cartoon he commissioned to get his point across. In the first panel of the cartoon, two fish swim in a bowl. One fish says, “I think the poor quality of the water is making us sick.” The other fish asks, “What’s water?” In the second panel, two office workers and an HVAC engineer stand near the same fishbowl. “Glad to be done with masks, sanitizers and social distancing forever!” says one office worker. “If we don’t improve our air quality in our buildings, we will keep getting sick in the future,” the engineer chimes in. “The air looks good to me,” says the other office worker. Beside her, one of the fish in the bowl is floating upside down with Xs for eyes, indicating it has died. The caption below the cartoon reads, “We don’t know who discovered water, but we’re pretty sure it wasn’t a fish,” which is a modern proverb attributed to various sources. That saying, McDonald asserted, sums up our own troubled relationship to air quality – because air is so fundamental to our existence, most of us don’t even think about it. But HVAC engineers think about air every day, all day, and it’s time to listen to them in the fight against airborne illness, he added.
“My frustration, which motivates me to write and speak out on the issue of air quality, is that our leaders are not getting it, and they aren’t listening to engineers,” McDonald said. “But the public health officials aren’t really talking about indoor air quality either, so a lot of politicians probably don’t want to go against the narrative.”
McDonald said that some of the anti-vaccine sentiments may stem from incomplete messaging that does not address indoor air quality. “Some of the resistance to masks and vaccines might be because people know in the back of their mind there’s something missing from the common messaging that is ringing hollow 18 months into this pandemic,” McDonald said. “We are constantly hearing, ‘Wash your hands, wear a mask and socially distance, where possible. We need to add simple, yet time-tested, ventilation strategies to our messaging, which we all know implicitly makes sense to folks from all political persuasions.” Perhaps with improved messaging from our leaders and initiatives to fix our broken HVAC systems, we can truly address this pandemic without arguing about the viability of masking and vaccines, he added.
McDonald said he is clear that vaccines are a key tool in beating this pandemic. But, without addressing the fundamental issue of indoor air quality, he said, we may be putting a “BAND-AID” on the current problem, missing out on the opportunity to improve public health for the long term.
DriSteem introduces Buyer’s Guide
EDEN PRAIRIE, Minnesota, 17 August 2021: DRI-STEEM Corporation, manufacturer of humidification, evaporative cooling and water treatment products, announced the introduction of a new buyer’s guide focused on humidification for electronics manufacturing.
DriSteem said it knows the importance of maintaining the appropriate humidity level within electronics manufacturing facilities, as proper relative humidity (RH) levels between 30% and 70% can significantly help decrease damage and stress to electronic components. When humidity levels are greater than 70%, corrosion can become an issue, the company said. In a controlled environment, manufacturers experience a reduction of electrostatic discharge, fewer brittle components, and fewer issues with soldering and de-soldering; they as well are able to create a safe environment for staff, the company added.
“This specific buyer’s guide is positioned to educate facility directors at electronics manufacturing plants about the importance of maintaining proper humidity to not only protect the products they are developing but to also keep workers safe and healthy,” said Randall Potter, Business Development Leader, DriSteem. “Many facility directors have expressed a need for educational materials and meetings. This buyers guide is an easily accessible way to help educate building management about the importance of humidity and how best to manage it throughout a facility.”

GrayWolf announces introducing smart IAQ and toxic gas probes
SHELTON, Connecticut, 12 July 2021: GrayWolf’s DirectSense II probes will now connect via Bluetooth LE wireless to Apple and Android devices, the company announced through a Press release.
GrayWolf said it DSII probes for Indoor Air Quality (IAQ) and toxic gas testing and monitoring will imminently have Apps for iOS and Android operating systems available free on the Apple and Google App stores. It added that it is possible to use a smartphone or tablet as a multi-parameter display or data-logger.
The company said that users can choose from over 25 smart IAQ, green building, industrial hygiene and HVAC sensors, including TVOCs (PID), Carbon Dioxide (NDIR), Ozone (electrochemical), CO, NO2, NH3, SO2, NO, Cl2, H2S, HCN, HCl, O2, H2, %RH and °C/°F. Each probe, the company said, accommodates from two up to eight true plug-and-play sensors into a single handheld, desktop or wall-mounted housing. The sensors offer low limits of detection and exceptional accuracy, the company claimed, adding that the CO2 sensor, for example, leads the IAQ industry at +/-35ppm over the key range, starting from 350ppm to 2000ppm (while +/-3% of reading above that up to 10,000ppm for CO2 toxic exposure use).
As monitoring IAQ parameters is a core application for GrayWolf, extensive development effort was put into assuring that the sensor smartboards would not introduce noise or degrade accuracy, stability or limits of detection (LODs) for the convenience of end-user swappable sensors, the company said. Other manufacturers, it pointed out, have prioritized convenience over performance.

Camfil donates air purifiers to Pertini
STOCKHOLM, Sweden, 15th June 2021: Camfil Italy in Cinisello Balsamo donated air purifiers to the municipality for the Il Pertini Cultural Center, Camfil said through a Press release, adding that it was a gesture of generosity and attention to the city, in which it has been operating for the last 46 years. The air purifiers, the company said, have been placed in the study room in one of the buildings, which has become an important step as many young students and professionals spend hours studying there.
Following an inspection, Camfil proposed the installation of three air purifiers in the study room. The clean air solutions, capable of purifying the air from pollen, bacteria, viruses, particulate matter, ozone, chemicals and other harmful contaminants, are also the same adopted by the French and Spanish regional authorities in the canteens, laboratories, and study rooms of their schools, Camfil said. Silent and with very low energy consumption, the City M air purification systems will guarantee about 16 changes per day of purified air, thanks to HEPA H14 filters, with a certified filtration efficiency of 99.995% even on the smallest particles in the air, it added.
Luciano Rogato, Managing Director, Camfil Italy, said: “We are humbled to have donated three air purifiers to the reading room of the Pertini Cultural Center, which plays a central role in promoting culture, socialization, and creativity in the Cinisello Balsamo community. It is an important contribution, as the local communities and public places have remained under strict restrictions due to the pandemic. Our clean air solutions ensure a healthy and safe indoor environment.”
Mayor Giacomo Ghilardi, said: “I thank Camfil for this donation to our city library, which is a hub for so many young people for studying, reading, and as a meeting place. Due to the health emergency, which is still ongoing, the Pertini was closed for some time, and we know how much discomfort this has created for many students and young professionals. The installation of these machines will allow more comfortable and healthy use of the indoor environments.”
LightAir says subscription strategy is yielding results
STOCKHOLM, Sweden, 12 June 2021: LightAir said its strategic focus on sales of air purification to offices and schools in Sweden is continuing to yield results. The LightAir Health+ offer provides clean, virus-free air and is offered in Sweden primarily as a subscription service, it said, adding that the number of subscriptions is growing continuously, rising from about 60, last summer, and soon likely to exceed 300.
The positive market reception in Sweden is exemplified by how Enskilda Gymnasiet – an independent secondary school in operation for over 100 years – is now expanding its two subscriptions to 30, LightAir said. The school carried out a six-month evaluation, which documented how individuals with asthma and allergies experienced relief from problems and that other students and teachers experienced improved air quality, LightAir said. Evaluation comments mentioned reduced fatigue, improved concentration and less drowsiness, it added.
“We are located in central Stockholm and are aware that we operate in an environment that is particularly exposed to traffic pollution,” said Jonas Persson, Project Manager, Enskilda Gymnasiet. “It’s important that students can stay healthy, cope with the school day and don’t get fatigued by bad air. It’s especially important that they are alert when final exams roll around. Students with pollen allergies are prone to tire easily and perform poorly.”
According to LightAir, Enskilda Gymnasiet is now installing a total air purification capacity of over 20,000 cubic metres per hour, along with a corresponding virus inhibitor capacity. Subsequent to the sale of the purifiers, the service will be delivered in the form of a three-year subscription, LightAir said.
According to LightAir, its Health+ subscription offer is the most comprehensive service offer available and was established in the Swedish domestic market in 2020. The offer has since been awarded the International Facility Management Association’s Nordic Innovation Prize, not least since it has the distinction of being able to destroy viruses while they’re still airborne, the company said.
“More and more businesses and organizations are opening their eyes to the challenges of indoor air,” said Joakim Hansson, Business Area Manager, LightAir. “This is also shown concretely by how we expanded our subscription base from 5 to 60 last summer, and from 60 to 160 by year end. This summer we have high hopes of reaching our goal of 300 Swedish subscriptions.”
Added Lars Liljeholm, CEO, LightAir: “We see that our strategic plan is promising and starting to bear fruit, while we have a long way to go with stimulating challenges ahead of us. We will become increasingly better at utilizing the competitive advantages we have in the nascent corporate market, not least in terms of purification efficiency and noise levels, as well as with an attractive and trouble-free subscription offer. Professional solutions will be the engine of our future growth. Through an increasingly successful domestic market, we are laying the foundation for establishment in selected international markets.
“We are in the middle of the demanding – but enjoyable – work of building a leading position in the commercial segment. Initially, the new strategy will affect sales when we change our revenue model, but in the long run, this will be crucial for the company and value creation for our owners. With that said, the consumer market will still be an important part of the future LightAir we are now building, which is why we have also recruited cutting-edge expertise and are continuously developing our international ventures and e-commerce.”

Camfil launches CamCarb VG engineered molecular filtration solution
STOCKHOLM, Sweden, 12 May 2021: Camfil launched the CamCarb VG engineered molecular filtration solution, which the company described as a robust solution suited for make-up air and recirculation air systems. The primary use of the technology, Camfil said, is the control of acidic gases that are responsible for the corrosion of electronics and electrical equipment in heavy process industries, such as pulp and paper mills; petrochemical refineries; mining and metal refining operations; and wastewater treatment plants. They are also suitable for lighter applications, such as the removal of noxious and odorous fumes generated outside airports, hospital helipads, cultural heritage buildings, and commercial offices located in city centres, Camfil added. The modules can be filled with different types of Camfil molecular filtration media to suit the specific customer application, the company said. There are two standard configurations of CamCarb VG: VG300 and VG440, it said, adding that the VG300 format is best suited for moderate duty (normally make-up air) applications, and the VG440 is best suited for light-duty (recirculation air) applications.
According to Camfil, CamCarb VG filters can be installed in specially designed housings, with options for front-loading, side-loading, or positive-seal side access (PSSA). They can also be used as replacements in housings and track systems produced by other manufacturers, the company said.
The modules are fully welded and constructed without adhesive to eliminate the possibility of off-gassing, Camfil said. They include a unique moulded mesh to allow the use of a full range of loose-fill media without shedding, it said. Many applications will require multiple molecular media to address a range of contaminants. The different media should be deployed in a series of layered modules. This layered approach will provide the highest removal efficiency, the longest life, and the lowest total cost of ownership (TCO), as each media can be changed when it reaches the end of its useful life, it said, adding that a blended-media, on the other hand, requires all the media to be replaced when just a single component has failed.
ASHRAE, IUVA sign MoU
ATLANTA, Georgia, 12 May 2021: ASHRAE and the International Ultraviolet Association (IUVA) have signed a new Memorandum of Understanding (MoU), formalizing the relationship between the two organizations, ASHRAE said through a Press release.
Charles E Gulledge III, 2020-21 ASHRAE President, and Ron Hofmann, President, IUVA, signed the MoU in April to further specify the path forward, ASHRAE said. The agreement defines parameters by which ASHRAE and IUVA will work cooperatively to promote the advancement of emerging research and technologies to support a more sustainable built-environment, ASHRAE further said.

ASHRAE publishes updated health care facility ventilation standard
ATLANTA, Georgia, 11 May 2021: ASHRAE has released an updated edition of ANSI/ASHRAE/ASHE Standard 170, Ventilation of Health Care Facilities. Making the announcement through a Press release, ASHRAE said the standard offers guidance, regulation and mandates to designers of health care facilities.
The 2021 edition, ASHRAE said, delivers critical guidance for designers and operators of these front-line facilities and incorporates 17 addenda to the 2017 edition of the standard.
According to ASHRAE, changes include:
- Expanded requirements to allow airborne infectious isolation room exhaust discharge to general exhaust under certain conditions
- Revised scope, with improved guidance on thermal comfort conditions
- Extensive modifications to address the Outpatient and Residential sections
- Extensive revisions to air filtration requirements
- Addition of new columns in the ventilation tables to prescribe filtration requirement and designate unoccupied turndown

ASHRAE supports USGBC IAQ schools survey and report
ATLANTA, Georgia, 29 April 2021: With technical support from ASHRAE, the Center for Green Schools at the U.S. Green Building Council (USGBC) published a new report on indoor air quality (IAQ) measures that schools have taken in response to the pandemic, ASHRAE said through a Press release.
The report, titled “Preparation in the Pandemic: How Schools Implemented Air Quality Measures to Protect Occupants from COVID-19”, presents the survey responses of school districts representing more than 4,000 schools serving over 2.5 million students in 24 states, on the protocols and operations plans implemented to mitigate the spread of COVID-19.
“Maintaining proper ventilation and good indoor air quality are vital in keeping school buildings healthy and operating as energy efficiently as possible,” said 2020-21 ASHRAE President Charles E. Gulledge III. “This report provides a wide-scale, foundational framework to school leaders and lawmakers alike towards the implementation of new building design guidelines and to advance health and sustainability goals, while instilling confidence in the places where people learn.”
According to ASHRAE, the report is the only known national view of air quality measures implemented in schools during the pandemic. It highlights what school districts have prioritized, which actions they have taken, how they have made decisions and what the consequences have been. The results of the survey show that schools have implemented some protective measures to improve IAQ, prioritizing ventilation and filtration to reduce the transmission of the virus, ASHRAE said. However, school districts still have unmet needs and face numerous challenges related to costs and outdated building infrastructure, ASHRAE added.
“Indoor air quality continues to be a critical concern as more teachers and students are returning to the classroom,” said Anisa Heming, Director of the Center for Green Schools, USGBC. “Increasing clean air circulation for our teachers and students is vital to promoting public health and is a key green building strategy for school buildings. Our aim with this report is to inform policymakers and nonprofits that support our schools of the challenges that our education institutions face in combatting the spread of COVID-19, particularly given the deficient state of many school buildings across the country.”
Additional findings from the survey include:
- The most-frequently-cited challenge to implementing protective air quality measures at schools was that school buildings were not designed to support the strategies that were being recommended.
- School districts that have been able to act have leaned heavily on their mechanical systems, such as increasing air supply through HVAC systems or upgrading filters to implement protective air quality measures for students and teachers.
- Only two-thirds of respondents were regularly monitoring IAQ before the pandemic, indicating that providing time, staff and funding for regular monitoring and data collection has not been a priority for many districts in the past.
- Respondents want to continue the measures implemented during the pandemic, citing student and teacher health. Seventy per cent of school districts plan to continue some or all of the strategies they have implemented.
“As schools re-open and develop health and safety plans to mitigate airborne transmission of COVID-19, many are prioritizing and upgrading current HVAC systems to provide the highest indoor air quality for building occupants,” said Corey Metzger, Lead, ASHRAE Epidemic Task Force Schools Team. “We know that improved indoor air quality has a positive impact on student performance and general well-being, and I’m hopeful that more schools will consider and implement the guidance provided by ASHRAE.”
Carrier launches Abound
PALM BEACH GARDENS, Florida, 27 April 2021: Carrier Global Corporation on April 26 launched Abound, which it described in a Press release as a new cloud-native platform, as part of its growing investment in digital solutions designed to give people confidence in the health and safety of their indoor environments. Abound is an open-technology platform that aggregates data from different systems and sensors and provides building owners, operators and occupants transparency into relevant and contextual insights about air quality, thermal comfort and other performance data, the company said.
“Abound will transform a building owner’s ability to optimize the indoor environment, boosting the confidence of each visitor and occupant,” said Dave Gitlin, Chairman & CEO, Carrier. “The access to real-time actionable data for indoor air quality and other building systems and sensors embodies the future of building health and performance for customers around the globe. With this launch, we are moving closer to establishing industry standards that will provide owners, operators and occupants greater confidence in their indoor spaces.”
According to Carrier, Abound is a cloud-native offering that uses advanced technology to make building environments more intelligent, efficient and responsive. It connects directly to existing building systems and sensors with no need for upgrades, retrofitting or replacements. And, unlike other building management platforms, Abound is designed to easily work with all systems regardless of manufacturer, to unlock and unite siloed data to provide more powerful, actionable insights, Carrier claimed. The platform can be rapidly installed and scaled and showcases data on a single pane of glass and via remote readings, the company added.
According to Carrier, a hallmark feature of the platform is the ability for building operators to benchmark building performance related to air quality, ventilation and humidity against the thresholds identified by certain air features within the WELL Building Standard (WELL) from the International WELL Building Institute, which works for achieving healthy buildings. Building owners will have the ability to display real-time information and messaging about a building’s health through the Abound application programming interface (API), which can be used to create digital wallboards and support mobile experiences, Carrier said.
“We’re proud that the thresholds in the Abound platform are based on the WELL Building Standard’s air quality features, helping Carrier to make something as invisible as air quality more visible and actionable,” said Rachel Hodgdon, IWBI’s President and CEO. “This platform will help streamline pathways for customers to measure, communicate and report their progress toward WELL Certification, advancing IWBI’s overall mission to advance people first places around the world.”
According to Carrier, Abound is currently being piloted across the United States, with customers in the commercial building, K-12 education and sports and entertainment industries, including Trust Park, home to the Atlanta Braves. It is also operating at Carrier’s world headquarters and building technology showcase, the Center for Intelligent Buildings in Palm Beach Gardens, Florida.
“We are thrilled to participate in the pilot of the Abound platform to give fans a safer and more informed spectator experience,” said Jim Allen, Senior Vice President of Corporate and Premium Partnerships for the Atlanta Braves. “The visual displays strategically placed throughout the stadium will provide our guests a real-time look at how our systems are working together to improve air quality. Sports bring people together, and the game just isn’t the same without our incredible fans here at the ballpark and we’re excited to welcome them back.”
While a tool for building owners, Abound was designed with building occupants and the general public in mind, Carrier said. It will make the invisible – air quality – visible through a smart, simple interface, and using its API and responsive display generators, building owners can communicate building health strategies, health performance metrics or the live indoor air quality summary through in-building digital displays, mobile applications or existing digital experiences.
“The launch of Abound underscores Carrier’s leadership in digital innovation and ability to move quickly to exceed our customers’ needs,” said Bobby George, Senior Vice President & Chief Digital Officer, Carrier. “The platform came together in a fraction of a year, and I couldn’t be prouder of the team. Abound’s platform architecture was designed around open standards and modern cloud native technologies and can quickly adapt to a wide range of integration and connectivity and scaling needs. The platform is comprehensive and delivers value to our customers through the complete integration of software, hardware and digital analytics.”

ASHRAE Epidemic Task Force releases updated airborne transmission guidance
ATLANTA, Georgia, 5 April 2021: The ASHRAE Epidemic Task Force released an updated, unequivocal statement on the airborne transmission of SARS-CoV-2 in buildings, ASHRAE said through a Press release.
ASHRAE released the following statement: “Airborne transmission of SARS-CoV-2 is significant and should be controlled. Changes to building operations, including the operation of heating, ventilating, and air-conditioning systems, can reduce airborne exposures.”
ASHRAE said the statement replaces its April 2020 statement, which said airborne transmission was “sufficiently likely” that airborne precautions should be taken. At that time both, ASHRAE said, the World Health Organization (WHO) and the Centers for Diseases Control (CDC) contended that transmission of SARS-CoV-2 was by droplet and fomite modes, not airborne. Subsequently, both have acknowledged the risk of airborne transmission indoors, ASHRAE added.
“This may seem like a small step, but we feel it is important to leave no doubt about our position, given the muted support for ventilation and filtration as important tools in the effort to stop the pandemic, from some organizations that should be leading more strongly,” said William P Bahnfleth, Chair, ASHRAE Epidemic Task Force.
According to ASHRAE, the Task Force has been developing and disseminating guidance for the control of airborne transmission of SARS-CoV-2 since its formation in March 2020. “ASHRAE volunteers have played a huge role in evaluating evidence and developing detailed guidance to improve indoor environmental quality,” Bahnfleth said. “The public, globally, is benefitting from the volunteer efforts of some of the most knowledgeable scientists and engineers in our field and this updated guidance is proof of it.”
To view the complete airborne transmission statement and other COVID-19 resources, ASHRAE suggested visiting ashrae.org/COVID-19.

ASHRAE announces call for abstracts for Winter Conference
ATLANTA, Georgia, 26 March 2021: Abstracts are now being accepted for the 2022 ASHRAE Winter Conference, to be held from January 29 to February 2, 2022 at Caesar’s Palace in Las Vegas, Nevada, ASHRAE said through a Press release.
With an eye on future resources, the conference seeks to present papers and programs that cover sustainable use of energy and water, reduction of waste and improved Indoor Environmental Quality (IEQ), while addressing other challenges and opportunities in facilities, applications and processes, ASHRAE said.
“It is estimated that the world population will grow from eight billion now to around nine billion in 2050; global GDP is expected to stabilize at +2%/year,” said Raul Simonetti, Chair, 2022 Conference. “This will increase the need for food, energy and other resources to support a growing population in the coming future. The 2022 Virtual Winter Conference will provide an opportunity to examine holistically – that is, at 360° – what we do and the way we do it in order to minimize the impact on our planet.”
According to ASHRAE, the following tracks are developed to support the conference theme, ‘Holism and Perspectives towards Decarbonization’…
- Buildings use a large share of a country’s final energy, particularly for heating, cooling and various services. Papers in the “Buildings at 360°” track will focus on explaining methods, equipment, systems and solutions to satisfy occupants’ needs, to guarantee buildings’ performances and resilience, and to save resources like energy and water.
- Energy is omnipresent in our daily lives in ways like electricity for appliances or heat and cooling for industrial processes. The integration of various energy sources, processes and transportation allows us to better exploit the available energy and reduce waste. The “Energy System Integration” track will explore renewables, fossil fuels, grid integration, aggregation, demand-side flexibility, smart devices, IoT, synthetic hydrogen and synthetic fuels, CCUS and electrification.
- Indoor environment is essential for our well-being and productivity, but is often regulated differently in various parts of the world due to local conditions, circumstances, history and traditions. Papers that explain local norms and trends with an eye on energy usage would fit in the “Environmental Health and IEQ in the International Arena” track.
- The “HVAC for Industrial and Commercial Purposes” track will focus on papers that examine the challenges and opportunities in improving energy efficiency of commercial and industrial facilities and transferring lessons learned to other types of facilities.
- Refrigerants play an important role in maximizing performances and minimizing direct and indirect GHG emissions. The “Refrigerants, Safety and Performance” track will focus on papers that present advancements and developments about flammability of refrigerants that can reduce the direct emissions, but that may have safety, regulatory and performance issues when deployed on the field.
- The “Refrigerants and Refrigeration” track will explore refrigeration systems, which generate and use cold for a range of processes, from food preparation and conservation to vaccine preservation, and from long-term protection of fragile ancient inks of historical documents to others.
- The “HVAC&R Systems and Equipment” track will focus on the development of new systems and equipment, improvements to existing systems and equipment and the proper application and operation of systems and equipment.
- The “Fundamentals and Applications” track will provide opportunities for papers of varying levels across a large topic base. Concepts, design elements and shared experiences for theoretical and applied concepts of HVAC&R design are included.

‘The cost of ignoring much-needed IAQ upgrades is far greater’
Amid the celebratory news of the roll-out of vaccination programs around the globe, we must all remember one of the biggest lessons that COVID-19 taught the world: Buildings – as they are designed, constructed, and operated and maintained – play a significant role in the health and wellbeing of not only their occupants but also the people and communities around them. These include our private commercial office buildings, residential buildings of all sizes, hospitals, entertainment venues, schools, public buildings and more.
We have also learned that infrastructure inequities in cities, states and countries across the globe – including those in transportation, healthcare, agriculture and housing – matter and have a big role to play when it comes to effectively managing a health crisis. And sadly, we learned that much like climate change, a pandemic will also disproportionately affect those with the least amount of resources.
The successful development of a vaccine for COVID-19 does not mean that we do not need to develop new practices when designing the places, spaces and communities around us. Why? Because vaccines are only one component of how we will recover and move forward. This is not a once-in-a-generation crisis. As a global community of sustainability and health professionals, we must embrace the lessons learned about virus transmission and apply them to ensure a permanent recovery and resiliency plan. History cannot repeat itself; the cost to humanity is too great.
This is a point in time when leadership matters. This is a point in time for deep inflection. And this is a point in time for purposeful and forward-looking action. We now have the opportunity – and a moral obligation – to completely re-think how our buildings and spaces should be designed, constructed, operated and maintained. We must turn our buildings and spaces into places that positively contribute to our health and wellbeing. That means that we have to take a fresh and honest look at the inequities in the communities around us and build back better with an eye toward achieving resiliency and equity. Multiple studies, including one just released by Oxfam, have found that the world’s richest people have made significant financial gains during COVID-19, while the world’s poor have fallen even further behind.
At USGBC and GBCI, we believe that better buildings and communities equal better lives. That’s why we are dedicated to continuing to invest in LEED, the world’s most widely used and trusted green building certification program. The success of LEED around the world is a testament to its effectiveness. As of this writing, we have more than 100,600 registered and certified LEED commercial projects, nearly two million registered and certified LEED residential units, projects in 181 countries and territories and nearly 205,000 LEED APs implementing the rating system around the world. Much like LEED’s commitment to environmental sustainability, human health and wellness strategies have been a foundation of the LEED program since its beginning, with over 70% of the rating system’s credits tying back both directly and indirectly to human health and wellness.
We know that addressing the systemic challenges revealed by COVID-19 won’t happen overnight and without significant planning. And while we know that addressing these systemic needs will not come without significant investment, we also know that healthy people, in healthy places and spaces, equal a healthy and robust global economy – and that the price we will pay for not addressing these needs will be far greater than addressing them now.
We can start by focusing our efforts on one of the primary targets of preventing virus spread: Indoor air quality (IAQ). Public health data has shown that buildings are safer to occupy when their mechanical systems, especially HVAC systems, promote good ventilation, air scrubbing and purification and enhanced outside air exchange. While these enhancements alone cannot eliminate the risk of virus transmission, they are a critical component of a larger mitigation strategy. Upgrades to outdated and inefficient HVAC systems in existing buildings across the world have been delayed for decades owing to cost concerns. However, the cost of ignoring these needed upgrades is far greater, as the pandemic has demonstrated in human lives lost, shuttered economies and schools and overburdened healthcare delivery platforms. Now is the time to invest in a resilient future and build back the trust between people and the buildings around them.
One way that USGBC and GBCI have strived to build back trust between people and the buildings around them is through our LEED Safety First Pilot Credit, related to managing IAQ as a component of our LEED green building rating system. The pilot credit builds on existing IAQ credits in LEED and helps building owners and managers ensure that IAQ systems are operating as designed. It also helps determine temporary adjustments to ventilation that may minimize the spread of COVID-19.
The pandemic has also called attention to the condition of schools. For well over a decade, USGBC has been advocating for a major and long overdue global investment in school buildings. We have already seen some of the adverse effects of schools being shut down and students being forced to learn from home for nearly a year, and the value placed on schools and in-person education is as high as ever. Now is the time to leverage that goodwill and invest in these facilities on a global scale, so that such disruptions never happen again. We need to ensure that every school across the globe has proper ventilation, air purification equipment, carbon dioxide monitors and proper outdoor air exchange in order to reduce the risk of spreading airborne pathogens as a key component in their back-to-school engagement strategy. Every student needs to have a chance to thrive, and a key component of that is a healthy school building.
These investments alone will not create a strong, healthy and resilient planet. We also need to look at cities and their infrastructures. Despite predictions of an exodus of people leaving dense urban population centers for the suburbs, we did not see the global abandonment of cities during the pandemic. Not everyone has the resources to simply pack up and leave, and many rely on the resources that cities provide. And many of those that did leave their cities simply relocated to other cities.
Cities that set themselves apart through substantial investments in sustainability, health and wellness, resiliency and equity will be the leaders of tomorrow. People by their very nature need to feel confident, comfortable and safe with the community around them. That’s why it is critical to provide a framework that communicates the importance of investing in urban infrastructure.
I am proud of the 114 cities and communities across the globe who have certified through the LEED for Cities and Communities rating systems, including the City of Dubai and the King Salman Energy Park (SPARK) project. These rating systems revolutionize the way cities and communities are planned, developed and operated, in order to improve their overall sustainability and quality of life. LEED for Cities and Communities is aligned with the United Nations Sustainable Development Goals and encompasses social, economic and environmental performance indicators and strategies with a clear, data-driven means of benchmarking and communicating progress. The rating system also addresses pandemic-specific challenges with two LEED Safety First Pilot Credits, one addressing the preparedness for pandemic planning and the other ensuring social equity in pandemic planning.
At some point, we will enter a post-pandemic world. However, leaders must not then forget the lessons learned from COVID-19. We must remain focused on letting science, data and the health and wellness of future generations drive each and every decision that we make. Better buildings and communities do lead to better and healthier lives. Let’s make that our collective legacy.

‘One cup at a time’
The cold chain may not come to mind when one thinks of a hot cup of coffee, but for Andrés Londoño and Santiago Londoño, third- and fourth-generation farmers of Colombian Exotic Coffee, this is the key to unlocking the critical tastes of coffee drinkers in the Middle East, which is a region known for its love of the brew.
“Our goal is to change people’s view on coffee, one cup at a time,” Andrés says, adding that the family has been farming in Colombia for nearly 100 years and selling the beans to different parts of the world. His cousin, Santiago adds that although the company is new to the Middle East market, it is confident about the appeal of its products, given its history. “Our main goal is to introduce our unique varieties, as these have never been seen before,” he says. “We take immense care of our product from start to finish, we feel that it is just as important for the end user to understand the great work that goes into it, and that is why we plan on educating the Middle Eastern market on what the procedure is.”
Every step of the way
There are different factors that must be considered in green coffee quality, Andrés says, and names variables such as flavour profiles or scores, physical preparation, shelf life and safety for the consumer as the most crucial. “All these are carefully considered in our farming practices,” he says, “but we have also noticed from different research and our own experiments that the storage conditions afterwards affect all these factors of quality – temperature being one of the most important variables for these changes.” Santiago, in agreement, adds that this was an important realization, considering traditionally, only moisture content has been the indicator for the preservation of coffee. “We have been researching and experimenting in our farms and warehouses and found out that when the three variables – water activity, moisture content and temperature – are not controlled, the sensory and physical quality can decrease substantially. In coffee, a slight decrease in flavour and physical quality is problematic.”
This also has ramifications in terms of safety, Santiago adds. “Not many people know that these fungi produce a toxin called Ochratoxin-A, which is resistant to temperature, which means it cannot be degraded in the roasting process or preparation of the beverage, and when drunk, the human body is not capable of liberating it, accumulating in it for long periods. Ochratoxin-A has also been associated with cancer development,” he says. “For this reason, assuring the proper conditions for storage and transportation not only helps us maintain the cup and physical quality but also helps prevents moulds and fungus to develop inside the bean, which, in terms of food safety, is very important.”
Andrés points out: “The benefit behind the mentioned features is that there is full transparency through unfiltered and untampered data, which will also allow us to provide feedback and request corrective actions, if necessary in real time or in future shipping. Once the product arrives at the DMCC warehouse, we will locate a data logger to record both variables. These will be checked periodically; deviations will be notified to the coffee centre, and corrective actions will be requested.”
Investment in quality solutions
Santiago also highlights the investment in data, adding that presently, the farms utilise a private software that was developed for the coffee industry and the different parts of its value chain. “It has a specific tool for each step of the value chain with accurate sample registration, monitors drying and storage conditions, green grading, sample roasting and cupping,” he says. “This data is useful to control and monitor our process and take corrective actions, if necessary. It can be easily shared with customers, as well. The idea in the near future is to integrate the last part of our value chain, which is the transit from Colombia and the storage and commercialisation here in the Emirates and even add the feedback of our customers; this way, we can really ensure quality of the whole coffee chain.”
A long-term outlook
The cost of implementing and maintaining a process cannot be avoided. However, for Santiago, it is more important to think of the benefits that such investment offers. “Specialty coffee quality is measured within Specialty Coffee Association (SCA) standards, which are between 80 and 100 points,” he explains. “If you produce at the farm a coffee that is at 89 points grade and is a complex exotic variety, like Geisha, you can sell it up to USD 70 per kg. We have calculated that during the 2-3 months transit between Colombia and the UAE, this coffee could lose 2-3 points in grade, because temperature and humidity degrades quality, so an 89-score coffee becomes an 86, which would be sold for USD 35 per kg, which means a loss of USD 35 per kg. If you bring 1.000 kg of this single exotic coffee in a container, it means you would lose USD 35,000 in this single lot. Keeping a complete cold chain from Colombia to UAE for a single container can cost about USD 20.000. It means a return of about 175% in terms of quality preservation.”
Condair releases whitepaper on healthy buildings
PFÄFFIKON/FREIENBACH, Switzerland, 14 February 2021: Humidity specialist, Condair, which specialises in humidity management solutions in the built-environment, has released a whitepaper, titled Making Buildings Healthier.
Making the announcement through a Press release, Condair said the paper contains information on how building managers can protect occupant health with a holistic approach to controlling their indoor environments.
According to Condair, the pandemic instigated by SARS-CoV-2 has focused public attention on the risks posed by viral transmission in buildings. Contributory factors that have been known about for some time, have now been placed centre stage, emphasising the influence that elements such as fresh air, temperature, minimum relative humidity and even sunlight all have on the spread of viruses.
The aim of the whitepaper is to provide an overview of these factors and promote dialogue amongst facility managers, users, and health and safety officers, enabling the right package of health protection measures to be considered, Condair said. The whitepaper also includes a checklist so that readers can take stock of their building’s current situation, discover the extent to which their premises protects against the spread of infections and identify where improvements could be made, the company added.
Oliver Zimmermann, CEO, Condair Group, said: “The Condair Group is the world’s leading specialist on humidity control, and for years, we’ve collaborated with scientists and healthcare experts to understand and promote the importance of optimal humidity for health. Through this research, we appreciate that humidity control is just one, but a decisive, weapon that can be used in the fight against respiratory infections.
“Upgrading our built-environment to better protect human health from the current COVID-19 and future potential pandemics, whilst not sacrificing the important gains we have made in energy efficiency, is the single largest challenge the HVAC industry will face in our lifetime. To achieve this objective, we must act as a sector to educate, cooperate and implement practical solutions as rapidly as possible. This whitepaper presents a clear and concise overview of the steps building operators can and should be taking to enhance occupant health, using a holistic approach, rather than a one-size-fits-all, to indoor environmental management.”
According to Condair, the whitepaper can be downloaded from www.condair.ae/making-buildings-healthier-whitepaper.

ASHRAE Epidemic Task Force releases updated Building Readiness Guide
ATLANTA, Georgia, 02 February 2021: With the performance of many HVAC systems in buildings still being evaluated, the ASHRAE Epidemic Task Force has updated its reopening guidance for HVAC systems to help mitigate the transmission of SARS-CoV-2, ASHRAE said through a Press release.
“The Building Readiness Guide includes additional information and clarifications to assist designers and commissioning providers in performing pre- or post-occupancy flush calculations to reduce the time and energy to clear spaces of contaminants between occupancy periods,” said Wade Conlan, Lead, ASHRAE Epidemic Task Force Building Readiness team. “New information includes the theory behind the use of equivalent outdoor air supply, method for calculating the performance of filters and air cleaners in series, and filter droplet nuclei efficiency that help evaluate the systems’ ability to flush the building.”
According to ASHRAE, major updates to the building readiness guidance include the following:
- Pre- or post-flushing strategy methodology: The strategy has been updated to include the use of filter droplet nuclei efficiency, which is the overall efficiency of filter, based on viable virus particle sizes in the air, to assist in determining the impact of the filter on the recirculated air on the equivalent outdoor air. This allows the filter efficiency as a function of particle size, using ASHRAE Standard 52.2 test results, to be estimated based on the expected size distribution of virus-containing particles in the air. This calculation is currently based on Influenza A data and will be updated as peer-reviewed research becomes available for the distribution of particle sizes that contain a viable SARS-CoV-2 virus. Additionally, a chart has been added to help determine the time to achieve 90%, 95% or 99% contaminant reduction, if the equivalent outdoor air changes per hour is known.
- Flushing time calculator: There is now a link to a view-only Google Sheet that can be downloaded for use, to help determine the available equivalent outdoor air changes and time to perform the flush. This sheet is based on a typical mixed AHU with filters, cooling coil, with potential for in-AHU air cleaner (UVC is noted in the example), and in-room air cleaning devices. Provided efficiencies of MERV-rated filters are based on the performance of over 200 actual filters from MERV 4 through 16, but the tool also allows users to enter custom characteristics for specific filters.
- The sheet also calculates the filter droplet nuclei efficiency, based on the cited research but allows a user to adjust the anticipated distribution of virus, as desired. It also allows specification of the zone (room) air distribution effectiveness from ASHRAE Standard 62.1 to account for the impact of the HVAC system air delivery method on the degree of mixing. Default calculations assume perfect mixing. Finally, the tool allows for the target air changes to be adjusted if an owner wants to achieve a different per cent removal in lieu of the recommended 95%.
- Heating season guidance: The guide now includes data to consider for heating of outdoor air and the potential impact on pre-heat coils in systems.
- Adjustments to align with Core Recommendations: The Core Recommendations were released in January 2021, and this guidance document needed to be updated to ensure that the information provided aligned with the intent of those recommendations. This included minimum outdoor air supply and filter efficiency requirements and their role in an equivalent outdoor air supply-based risk mitigation strategy.
According to ASHRAE, the guidance still addresses the tactical commissioning and systems analysis needed to develop a Building Readiness Plan, increased filtration, air cleaning strategies, domestic and plumbing water systems, and overall improvements to a system’s ability to mitigate virus transmission.
Building for the “new normal”
As the world continues to grapple with an ever-shifting economic landscape, owing to the COVID-19 pandemic, stakeholders in the building sector across the GCC region have observed how the pandemic has triggered an evaluation and reassessment of priorities. Ashok Jha, Head FM and Retrofit Projects, Universal Voltas, points out that the unprecedented disruption caused by COVID-19 has prompted many organisations to take actions they have been putting off for some time, including launching new digital services and evolving their business models, enabling greater flexibility in their working and implementing cost optimisation measures.
However, Jha says, perhaps the most notable trend would be the move towards a greater number of retrofit projects in the region. “Because of the COVID-19 pandemic, the oil prices plummeted to one of the lowest levels and government revenues went down in the GCC region,” he says. “This has led to reduced spending across all sectors, including new construction, with the current market seeing greater push towards shallow retrofitting, deep retrofitting, energy conservation and reducing the building carbon footprint in the existing buildings to make them more sustainable.” Jha says that since the number of existing buildings in Oman, Kuwait and the UAE is very high compared to new buildings, there was also a need to address the physical deterioration of the buildings, due to functional and economic obsolescence, and to make them more sustainable. “Because of this, there is a surge in demand for the retrofitting of the existing buildings across the GCC region,” he says (see sidebar).
Andrea Di Gregorio, Executive Director, Reem, Ras Al Khaimah Municipality, also believes the region is poised to see a strong pipeline of retrofit projects. “More focus is being put in refurbishing existing buildings, to bring them up-to-speed with the latest best practices in sustainability,” he says. “We see an increase in interest from building owners in retrofit activities, and we expect this interest to further increase throughout 2021 and in the coming years.”
Energy efficiency and sustainability
Another major driver for retrofits is the move towards energy efficient and sustainable practices, which has long been heralded by experts in the sector. Jha points out that because of the detrimental impact of buildings on the environment, with occupied buildings and the construction sector accounting for 36% of the global energy consumption and nearly 40% of total direct and indirect CO2 emissions according to International Energy Agency (IEA), the UAE has begun to actively transition into smart and sustainable cities, which has turned the focus on the energy efficiency of the buildings, specifically existing ones.
In addition to its impact on overall sustainability efforts, much of the move can be attributed to growing awareness on return of investment in terms of reduced operational cost. As Jha points out, retrofitting primarily refers to the measures being taken to replace legacy energy and utility systems with new and energy-efficient technologies. “These technologies not only reduce energy consumption and decrease carbon emissions but also lower maintenance costs, improve safety, enhance productivity, boost property valuations and also prolong the useful life of the assets and the building as a whole,” he says. “In a nutshell, we can say that OPEX of the building reduces and the asset value increases. Hence, it is becoming important day by day to retrofit buildings to not only make them more sustainable for the future but also to derive economical value by reducing the operational cost and, in turn, optimise the rentals and make them more lucrative for the tenants.”
Weighing in, Di Gregorio says that sustainable buildings often result in lower life cycle cost of the building itself. “If sustainability features are carefully selected, operational savings – in terms of energy and water usage and equipment maintenance – typically exceed any incremental investments that those features require,” he says. “For this reason, in a perfect market, where developers are able to fairly monetise their investments in higher quality buildings, we would expect for tenants any rent premiums for more sustainable buildings to be exceeded by the value of operational savings.”
Jha adds that as energy prices continue to rise, the relative benefits of energy efficiency will become increasingly important, and this is leading to a huge surge in demand for equipment, such as Smart LED lights and motion sensors, air curtains and FAHUs, energy-efficient AHUs, FCUs or split units and VAV systems. This has also led to greater demand for water usage reduction through the use of low-flow fixtures, sensors, waterless urinals and low-flush WCs, and also for photovoltaic panels on rooftops to generate electricity from the solar power, among other solutions.
A renewed focus on IAQ
While the return on investment (ROI) from retrofitting for energy efficiency is becoming clear, stakeholders are hopeful that the new wave of retrofits would also accommodate enhancements of indoor air quality (IAQ), which has been typically overlooked over the past years. Di Gregorio says that he believes this would be the case. “There is increasing interest in IAQ, partly driven by COVID-19 concerns,” he says. “Some awareness and technical barriers are there; nonetheless we foresee development in this area in the future.”
Jha shares a similar opinion. He says: “Fear of pandemic is looming large in the minds of the people, and therefore, while carrying out the retrofitting of their buildings, owners are ensuring that retrofit projects also take into consideration IAQ of the buildings, where people are currently spending more than 90% of their time and also to reduce the chances of contamination through virus, bacteria, moulds and fungi.”
Di Gregorio says there is a lot of focus on safety and security from building owners, particularly in what concerns disinfection of common areas. “This sometimes adds to other measures, like filtration, turning into improved air quality,” he says. Jha adds that some of the measures that building owners are taking include Demand Control Ventilation through C02 sensors, fitting volume control dampers, ultraviolet lamps in AHUs, ultraviolet germicide irradiation and MERV 13/14 filters. He further adds that there has been an increase in the use of humidifiers and dehumidifiers to maintain humidity in the range of 40-60%, where the microbial and fungal growth is minimal.
Jha also says that the majority of the offices are allowing their staff to work from home and that people are spending more than 90% of their time indoors. “This further necessitates that apt measures are taken by the occupants to ensure proper lux levels, ergonomics and IAQ, as these will have a profound impact on their health and wellbeing and, in turn, impact their productivity,” he says. “Hence, there cannot be a better time than now to address the Indoor Environment Quality (IEQ) issues, if any.” Jha says these are the factors driving a lot of investment being done by the property owners in the built-environment to retrofit their buildings to ensure proper IAQ against the traditional retrofit, where emphasis was mainly towards energy efficiency.
Making a case for retrofits
Keeping in mind the tangible and intangible benefits of retrofitting, Di Gregorio believes there is more than enough evidence to drive building owners to invest in such initiatives. “If building owners are not thinking about retrofits, they definitely should!” he says. “Retrofit projects tend to have very favourable returns. We are observing that for comprehensive retrofits of commercial buildings in Ras Al Khaimah, the payback time is 3-5 years. And the contracting standards that are being adopted often provide forms of guarantees for the investor on those returns.”
Jha, agreeing, says that in spite of the change in the occupancy profile of buildings, property owners must continue to retrofit within the built-environment. “Retrofitting of existing buildings offers tremendous opportunities for improving asset performance in terms of utilities,” he says. “Retrofitting also offers a potential upside in the overall performance of the building through improved energy efficiency, increased staff productivity, reduced maintenance costs, and better thermal comfort.” Jha believes that such key drivers should serve as a motivation and incentive for building owners, who are on the fence about investing in retrofit projects.
A complete 180
In view of the shifting political landscape, how will the new administration affect the country’s commitment to climate change mitigation?
It’s going to be a complete 180 from the [Donald] Trump administration. In [Joe] Biden’s plan, he mentions “a historic investment” in upgrading four million commercial buildings to return almost a quarter of the savings from retrofits to cash-strapped state and local governments. Specifically, it says that he will “mobilize a trained and skilled American workforce to manufacture, install, service and maintain high-efficiency LED lighting, electric appliances, and advanced heating and cooling systems that run cleaner and less costly”.
Given our focus on energy savings, I think that this will be great for business as well as for building owners. Some suggest that large rebates may be involved to directly incentivise businesses and make it affordable to pursue these upgrades.
That being said, although the Trump administration was not at all focused on energy conservation, I found that individual building owners and managers were still pursuing these measures during the Trump administration. Most organisations in the US are interested in conserving energy and saving money. With government focus and incentives, it will just accelerate the demand.
In view of COVID-19, do you see a greater uptake of IAQ equipment throughout the country?
Yes, for sure. However, these things come with a cost, and with COVID destroying the economy, there is going to have to be some kind of funding or incentives given to get these types of retrofits in place. I will give you an example. Two of our clients in the US requested ultraviolet lighting proposals to be retrofitted into their air handlers and FCUs. We put together the proposals and delivered them; however, neither has been approved yet due to the difficulties these buildings are facing financially due to delinquent tenant rent payments and occupancy.
Another interesting fact is that most of these IAQ retrofits are not intended to deliver energy savings. That is another hurdle to getting these projects approved. One last point – and I don’t think this is limited to the US – customers in the UAE have also asked for ultraviolet lighting to be installed, and it is still difficult to get the approval here, for the same reasons mentioned earlier.
Has there been a heavier-than-usual concentration on the air side of things from building owners, tenants and manufacturers?
The EPA has recommended that guidance provided by the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) for managing IAQ during the current pandemic be followed. ASHRAE’s statement is as follows: “Transmission of SARS-CoV-2 through the air is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including the operation of heating, ventilating, and air-conditioning systems, can reduce airborne exposures.”
The two solutions we have seen implemented in the buildings we service in the USA are AHU filter upgrades and increasing the intake of outside air into the building. Both of these changes are very effective and relatively easy to implement as well as low cost.
How has the change in occupancy profile thrown everything into a state of chaos in terms of commercial and residential property requirements? Will this be a driving force towards more retrofit projects?
In terms of energy conservation measures, this has thrown everything into a state of chaos. One, the commercial buildings are hardly occupied, which has led to energy bills dropping dramatically. However, with less occupancy comes less rent, thus less money to invest in retrofit projects. In addition, building owners, who are still looking for energy savings, are hesitant to move forward, because they are not sure if and when tenants will be returning to the buildings, so to be honest, unless it’s a well-funded customer, this could actually slow the conservation efforts.
Residential buildings face the same issue. People are leaving the dense, populated cities, preferring the suburbs right now, leaving residential multi-family buildings unoccupied and no rents being paid. Until we get herd immunity with the vaccine, and people are comfortable returning to the cities to work and live, this will continue to be challenging.
How have these trends potentially influenced building owners?
As I stated earlier, most building owners are hesitant even if they want to move forward on new projects, given the current situation. However, some forward thinkers, with ability and the confidence that things will return to normal, are taking this time to invest in conservation efforts, so that when the buildings are occupied, they can take advantage of the maximum savings.
Have there been efforts to retrofit among specialised facilities such as healthcare?
At the moment, it is difficult to even get a meeting with a healthcare facility in the US. They are overwhelmed and have overcapacity with COVID patients and are focused on saving lives before anything else. Their priority right now is the conservation of life.
Has the pandemic finally trained the spotlight on the importance of having a balance between energy efficiency and IAQ?
I think that yes, people will be investing in IAQ, or at least investigating their options, especially healthcare facilities and the like. However, in my experience, to be honest, it’s a tough sale, unless there’s a Return on Investment (ROI) in the project. Having said that, UV lighting does have some energy-saving benefits, so maybe a combination of IAQ and energy savings should be highlighted to the building owners in the presentation of these retrofit solutions.
Retrofitting in Kuwait, Oman and the UAE
COVID-19 has had a significant adverse impact on organisations, people’s health, their livelihoods and the economy at large in the GCC region countries, says Ashok Jha, Head, FM & Retrofit Projects, Universal Voltas LLC. However, Jha is quick to point out that while the duration and severity of COVID-19’s impact on economies and sectors will undoubtedly vary, companies and governments in the GCC region have done well to set in motion a “look ahead, anticipate, innovate and adjust” roadmap, which has led the construction sector to focus on energy optimisation and retrofitting in existing buildings, which is a key to sustainable construction.
Citing figures from Global Data, a leading data and analytics company, Jha says that Oman’s construction industry contracted sharply in 2020, plummeting by nearly around -10.3%. “The industry is struggling with challenges presented by the COVID-19 outbreak, low oil prices, and the impact of sovereign credit rating downgrades,” he says. Further compounding the downside risks to the outlook for the industry, the Omani Government has had to rationalise spending.”
Jha adds that given the limited prospects for the government to boost investment in infrastructure and other investment projects, a recovery in the construction sector is expected to be very slow. “Global Data currently expects the construction industry to fall further in 2021, with output contracting by -5.8%,” he says. “The fiscal plan by the Oman Government is intended to reduce public debt, increase the state’s reserves, and diversify revenue away from the oil sector.”
Owing to these factors, Jha believes that new construction spend will be very minimal, and more impetus will be on the retrofitting, deep retrofitting, fit-outs and energy performance optimisation in the built-environment in Oman.
Kuwait has faced similar challenges, Jha says, adding that the construction market shrunk in the year 2020 at about -9.5% approximately, as per Global Data. “The construction industry is struggling with the challenges presented by the outbreak of COVID-19, low oil prices and the impact of sovereign credit rating downgrades,” he says. “Because of this, focus is more towards existing buildings in Kuwait.”
Jha adds that within the built-environment in Kuwait, residential buildings constitute around 81%, commercial buildings are 11%, whereas government buildings constitute four per cent; the remaining four per cent includes commercial, industrial, agricultural and services. “Also, Kuwait has one of the highest per capita electricity consumption and carbon footprint globally, which further necessitates the retrofitting of the buildings to make them more sustainable,” he says. “All the above factors, along with the economic strain, is forcing Kuwait to focus on energy conservation, deep retrofitting, retrofitting and fit-outs in the built-environment with a very minimal spending on new construction.”
Sharing observations on the UAE market, in particular, Jha says that the COVID-19 outbreak, coupled with low oil prices, has led the construction output in the UAE to contract by nearly 4.8% in 2020, but that a rebound is expected in 2021, as per Global Data. “New project opportunities are expected to be minimal in the coming quarters, as the government is consolidating its widening fiscal debt and COVID-19-related force majeure,” he said. “Over the medium- to longer-term, government investment will remain focused on upgrading physical infrastructure and reforming the financing and regulatory environment.”
Jha adds that the UAE has set high targets for building retrofit, which are reflected in the UAE Energy Strategy 2050 and the Dubai Integrated Energy Strategy. “The latter targets an overall 30% reduction in energy and water use by 2030,” he says. “To support this, Etihad ESCO aims to retrofit 30,000 buildings in the next 10 years and generate 1.68TWh energy savings and around 5.64 BIG of water savings by year 2030.”

Climate change and the larger picture of finances
Q&A: James Brainard, Mayor of Carmel, Indiana, United States
We have succeeded admirably in our fight against the depletion of the ozone layer through collective effort, through a cohesive, consensus-based approach of finding economically and technically sound alternatives to ozone-depleting refrigerants. How much confidence do you take from what has been a marvellous example of social cooperation?
We did the summit in the form of the Montreal Protocol over concerns of huge spike in cancer deaths, so it was a great example of world leaders coming together to study a problem, devise a solution and then go back to their countries to fix the problem. It shows diplomacy and recognition of common challenges can be good.
In the same way, could we not find a financially feasible, well-structured long-term plan to curb the widespread misuse of energy and general profligacy through steady and substantial investment in the infrastructure needed to achieve the goal?
You have identified the problem in the question, and we have to find the means of accomplishing this. We have to look at the larger picture of finances – the health impact of pollution; the cost of famines; the cost of relocation, if we have a rise in sea level, leading to the displacement of people from major cities; and the cost of possible conflicts arising out of this. But more specifically, we need to recognize many jobs are dependent on the fossil fuel industry. So, we can make those changes, but we have to recognize that we need to look out for investment of industry, we still need to fly airplanes. But, we have a saying in the US, ‘low- hanging fruit’. So, there are many easy things we can do to clean the environment and reduce fossil fuel use, and those are what we can focus on with recognising that we have to protect people’s jobs in the fossil fuel industry and that many are invested in the fossil fuel industry.
Would an approach of self-financing the fight against global warming by developing an energy budget in every city, town, state and country across the world be a possible way out, as propounded by George Berbari, the CEO of DC Pro Engineering? I am referring to a structured, long-term carrot-and-stick approach, where individuals and organisations occupying residential and commercial buildings could be rewarded for being energy efficient and penalised for being inefficient, with the penalty being slightly higher than the reward to create a positive budget, a surplus, which could be used for giving rebates to homeowners for improving insulation, glazing, etc., for developing infrastructure to lower primary energy use, for building thermal energy networks, even District Energy schemes… anything that would effectively fight climate change.
I think it would help. The colloquial shotgun approach, where we undertake to do a lot of small things. I think your idea of financial incentives and disincentives is good; and tied to that what needs to happen is disincentives need to increase over time and incentives need to go up and come down. It is certainly a system we need today. You could still pass laws, where each year, the incentives and disincentives change, to encourage disincentives to go up and incentives to go away. The tax system is also there. Or, it could be a separate tax, a carbon tax, and it has been discussed here since the late 1980s.
Economists believe such an approach to conserving primary energy is feasible, but democratically elected local and federal government leaders and local mayors have limited terms and, generally speaking, give priority to short-term problems, the solving of which gives them immediate political benefits, as opposed to decades-long and daunting task of curbing energy use through a financial mechanism and other initiatives, which might also be viewed by the city’s inhabitants that make the electorate, as adding to existing costs and impairing their personal and corporate competitiveness. In your case, you are one of the longest-serving mayors in the state, having been in office since 1996 over seven consecutive terms. Did that give you a canvas to paint a long-term vision? How effective was the approach? Did it help you shape regulation and enforcement at a city level? Were you able to raise greater awareness on the human impact on climate change and bring about a consensus-based change in energy use behaviour in Carmel?
We are a suburb of Indianapolis, which has a population of two million people. We are 100,000 people in Carmel. Now, places like Dubai and Doha require automobiles, owing to the urban sprawl. Generally, we need the automobile to go anywhere. We have looked at the problem and have a series of PPPs, where one can live, work, go to restaurant and engage in recreational activities without having to get into an automobile and, as a result, lower the consumption of fuel.
The average American spends two hours a day in automobiles, but in Carmel, businesses, houses, schools are all here. We have adopted land use development differently, so people can live, work and go to a restaurant all in the same area, and we tried to design our downtown not for automobiles, and it has cut down fuel use. In Carmel, it is 15 minutes to half an hour of automobile use per person, so it is much, much less [than the national average].
We have a legal structure in the state of Indiana that makes decisions on building codes, and they have done less than what I would like to see, but we have contract to have a much more efficient build. We have the example of the Energy Center in Carmel. We have cold winters and hot summers in Carmel, and we are using energy all year long to either heat or cool our buildings. And if you have an individual heating or cooling system, it starts and stops and is energy inefficient. And so, we have developed the Energy Center in the city, and it uses 50% less energy. And we would like to see this being applied across the city.
If energy is scarce and its excessive use damaging to the environment, should people be allowed to consume as much as they want to, as long as they are paying for it? Should affordability be a sole factor? Could we change that mindset and, at the same time, take care not to infringe on personal freedom and quality of life?
I have thought about it, and I believe in a capitalistic and free market approach. And there is a way to fix it, which is you pay USD 10, say, for 100 units of use, USD 15 for the next 100 units, and USD 20 for the next 100 units. And so the more you use, the higher the price. And it is a good system, because it penalizes the people to use it, and at the same time, they have the freedom to use it. In the case of steel production, maybe that may be very important for the economy and jobs, and so there should be a different model. You have to look at the situation where we can improve the environment, decrease carbon and increase quality of life.
Have you established a carbon neutrality goal for Carmel, like Copenhagen, for instance, where we are seeing a consensus-based approach involving all political parties, underpinned by the thought process that environmental action needs to be bipartisan in nature? Or are the political dynamics different in the United States?
It’s a good question. Our city is mainly Republican, and is fiscally and economically conservative. Some years ago, a seven-member council introduced a carbon neutrality goal, which is not mandated, however. We know we will get there, because the technology is there. It is not time bound. It is a legislative body that passed a law that laid out a carbon neutrality goal.
We have been measuring progress in reducing carbon. Every year, we are measuring how much energy the city is using on a per capita basis, because the city is growing. I don’t know if we have done enough yet, but we are making progress. I firmly believe technology will save us.
The fight against climate change needs to be a non-partisan effort within cities, states and nations. What we have seen is a vastly polarising view within the United States. With Joe Biden set to take the reins, how soon can we expect to see the United States aligning itself in a more profound manner to the Paris Agreement?
I am a Republican, and my undergraduate degree was in history, so I tend to think not today but historically. At the turn of the century, Ted Roosevelt, a Republican, set aside millions of acres in the US for the National Parks system. And President Eisenhower in 1952 established the Arctic Reserve in Alaska, and he was Republican, as well. And President Nixon was the one who set up the federal EPA. Republicans signed a law that amended our Clean Water Act. They passed a whole series of environmental laws. President Reagan led on the Montreal Protocol for the ozone protection initiative. George HW Bush and George Bush came from a state that produces a lot of oil, and yet they established a system of hundreds of windmills. Over 120 years, Republicans and Democrats have come together in a non-partisan manner. And they will come back; this anomaly has been only for a sort period of time. Clean air and water are non-partisan issues. Disagreement will come only in terms of jobs.
On December 11, 2020, the United States observed a new daily death record of 3,055 individuals, more than the number of people who died in Pearl Harbour or the September 11 attacks on the twin towers in New York City. The coronavirus cases have risen sharply in Carmel, as they have elsewhere in Indiana and across the country. What measures have you taken in Carmel to safeguard residents through better indoor air quality (IAQ), with science advocating more fresh air changes and maintaining Relative Humidity between 40% and 60% in buildings?
I think one good thing that has come from the pandemic is recognition of IAQ being important, and there are great many entrepreneurs in the US selling systems that clean the air. Our City Hall operates a new system that every few minutes recycles the air and filters and cleans the air in the building; and it is energy efficient. And building owners throughout the US are adopting this. I see this as a positive thing that has emerged.
I have put a taskforce in Carmel. We also have generated messages through emails and print newsletters and social media. We have used an entire gamut of ways to talk to people, not just about IAQ but also about things to do to handle the pandemic in a better way. Our city had done a good job till the first week of October, testing and quarantining people. It worked through summer, but when people came indoors when the temperatures fell, it went bad. We had our first set of vaccinations, yesterday (the interview with Mayor Brainard took place on December 15), so we hope to be in good shape by March or April 2021.
There are those that are saying building industry stakeholders simply need to reverse the polarity on their thinking when it comes to budgeting for indoor air quality and that we need to raise buildings fit for purpose.
Yes, it’s a good point. Energy for buildings is important, but I think IAQ is something that would work very well. We have tax incentive to make buildings more energy efficient, and over time if building owners do not take action, a penalty would start; and simultaneously, there will be a reduction in taxes for people who make more energy-efficient buildings. And that puts the burden away from the average taxpayer. Yes, I do believe in an incentive and disincentive system for establishing good IAQ.
How to kill enveloped viruses in just 30 minutes
Poor ventilation in closed indoor environments is associated with increased transmission of respiratory infections. There have been numerous SARS-CoV-2 transmission events associated with closed spaces, including some from pre-symptomatic cases. The role of ventilation in preventing SARS-CoV-2 transmission is not well-defined – that is, by preventing dispersal of infectious particles in small waterdrops to minimise the risk of transmission or preventing transfer of an infectious dose to susceptible individuals.
SARS-CoV-2 is thought to be primarily transmitted through large respiratory droplets; however, an increasing number of outbreak reports implicate the role of aerosols in SARS-CoV-2 outbreaks. Aerosols consist of small droplets and droplet nuclei, which remain in the air for longer than large droplets. Studies indicate that SARS-CoV-2 particles can remain infectious on various materials, such as air conditioning surfaces in air ducts and air handlers, as well as in aerosols in indoor environments, with the duration of infectivity depending on temperature and humidity.
While HVAC coatings are often the most cost-efficient insurance for the longevity of your air-handling system, there’s much more to them than just increasing your building systems’ lifespan. The rising demand for antimicrobial coatings was triggered by the COVID-19 pandemic and tenants worried about their wellbeing from airborne diseases. In the same category, antimicrobial coatings can make a huge difference for indoor air quality and occupant safety. There are a number of HVAC coatings that drive energy savings, primarily desiccant-coatings.
Found on AHU heat exchangers, coils and in duct systems, they enable recovering heat and moisture, which then helps building owners to save on operational cost. Recent studies have uncovered an extreme antimicrobial effect of desiccant coating systems, in high relative humidity, as present in air conditioning systems. It appears the surfactants can break the exterior protein of a virus or bacteria strain. Once the protein is destroyed, the virus cannot attach to cells and transfer or alter human ribonucleic acid (RNA).
In many circumstances, once microbes have begun to proliferate on a painted surface, constant cleaning and disinfecting is required to keep growth under control, which is highly unwanted inside an air conditioning system. Recognising that the ability to clean constantly is unreasonable in most air conditioning systems, the best weapon against corrosion and microbial growth is an antimicrobial paint that prevents growth of, or eliminates, bacteria and viruses. Both the coating and the possible active ingredient should not produce any environmental, safety or health issues during application. Any off-gas from the film is unwanted, because ideally, the coating must be applied to air conditioning systems in operation without any concern of release of poisonous additives.
Antimicrobial efficacy based on silver ions
Generally, an antimicrobial surface contains an additive, like Agion, which inhibits the antimicrobial property that is composed primarily of silver ions, which have been proven in antimicrobial use throughout history. It incorporates silver ions inside a zeolite carrier, providing an area for these ions to exchange with other positively charged ions – often sodium – from the moisture in the environment.
Once exchanged, these now “free” silver ions are attracted to oppositely charged hydrogen ions, commonly found in most bacteria and microbes. The bacteria and microbes’ respiration and growth are now abruptly halted, since the hydrogen ions are no longer available. Silver based antimicrobial coatings contain a pesticide additive that evaporates slowly from the coating surface and raises questions on the durability of discharge. In Europe and North America, these coatings require a registration by the government authorities.
Antimicrobial efficacy based on desiccation
Enveloped viruses, like the H1N1 influenza virus, Corona (COVID-19) and bacteria have membranes of protein and enzymes to protect the infecting contents. The spreading of the viruses and bacteria in closed spaces and air conditioning systems is carried out by smaller aerosols. Alternative antimicrobial functionality is based on desiccation, a physical process to extract the moisture from the virus and bacteria particles. This approach may seem relatively primitive; however, it is extremely effective in slowing down or even preventing microbes from spreading and transmission. This method is similar to other physical treatments, such as UV irradiation, filtering and heating.
Desiccant coatings inactivate a wide variety of microbes that adhere to the surface through their hydrophilic surface properties. The antiviral functionality of the coating has been tested on the Phi6 virus, which is commonly used as surrogate for enveloped Corona viruses.
A recent study shows that a desiccant coating can have an extremely quick kill-rate of enveloped viruses after just 30 minutes.
Further studies have proven that strong antimicrobial working was additionally confirmed. Surface activity results in full kill-rates of > 99,99%, which were confirmed on the following micro-organism strains:
- Klebsiella Pneumoniae
An important note should be added to this paper: No claim or assertion should be made that the antimicrobial properties in the coating will improve air quality or eliminate the threat of disease-causing microbes in the air supply system. A healthy indoor air system is highly dependent on a combination of design, maintenance and cleaning measurements that are incorporated in the air conditioning system and facility management procedures.

8 Evaluation of Phi6 Persistence and Suitability as an Enveloped Virus Surrogate Aquino de Carvalho, Nathalia; Stachler, Elyse N.; Cimabue, Nicole; Bibby, Kyle Environmental Science & Technology (2017), 51 (15), 8692-8700CODEN: ESTHAG; ISSN:0013-936X. (American Chemical Society)
Recent outbreaks involving enveloped viruses, such as Ebola virus and SARS COVID-2, have raised questions regarding the persistence of enveloped viruses in the water environment. Efforts have been made to find enveloped virus surrogates due to
challenges investigating viruses that require biosafety-level 3 or 4 handling. In this study, the enveloped bacteriophage Phi6 was evaluated as a surrogate for enveloped waterborne viruses. The persistence of Phi6 was tested in aq. conditions chosen based on previously published viral persistence studies. Our results demonstrated that the predicted T90 (time for 90% inactivation) of Phi6 under the 12 evaluated conditions varied from 24 minutes to 117 days depending on temperature, biological activity, and aq. media compn. Phi6 persistence was then compared with persistence values from other enveloped viruses reported in the literature. The apparent suitability of Phi6 as an enveloped virus surrogate was dependent on the temperature and compn. of the media tested. Of evaluated viruses, 33%, including all conditions considered, had T90 values greater than the 95% confidence interval for Phi6. Ultimately, these results highlight the variability of enveloped virus persistence in the environment and the value of working with the virus of interest for environmental persistence studies.

Two bacteriophages, .vphi.6 and .vphi.8, were investigated as potential surrogates for H5N1 highly pathogenic avian influenza virus in persistence and chlorine inactivation studies in water. In the persistence studies, .vphi.6 and .vphi.8 remained infectious at least as long as the H5N1 viruses at both 17 and 28 degrees C in fresh water, but results varied in salinated water. The bacteriophage .vphi.6 also exhibited a slightly higher chlorine resistance than that of the H5N1 viruses. Based upon these findings, the bacteriophages may have potential for use as surrogates in persistence and inactivation studies in fresh water.

Daikin India acquires Citizen Industries
GURGAON, India, 16 December 2020: Daikin Airconditioning India acquired India-based AHU manufacturer, Citizen Industries through a share-purchase agreement, signed on December 15, the former said through a Press release.
According to Daikin, the acquisition will provide prominence to its current infrastructure influence and help increase its penetration across various applications.
Citizen Industries has two manufacturing units, a big base of R&D engineers and service technicians that Daikin said would complement its people strength. The integration of the two companies, Daikin added, would result in joint sales velocity; acquiring of ongoing air-side maintenance contracts; expansion into the applied and VRV solution business, including air side; a horizontal collaboration with American Air Filter (AAF); and catalysing economies of scale at Daikin’s Neemrana factory in the western Indian state of Rajasthan and its R&D centre.
Daikin said its acquisition of Citizen Industries mirrors its assertive philosophy of identifying opportunities ahead of time and building value around its offerings, while keeping customer requirements at the forefront to create a sustainable business, faster than the rest.
Lexzander, Emitech enter into a JV
DUBAI, UAE, 01 December 2020: Lexzander and Emitech have formed a joint venture (JV) in a bid to give
end-to-end solutions for MEP works, with the former saying it is coming forward with construction management and engineering capabilities and the latter saying it is bringing logistics and project execution expertise to the enterprise. Speaking to Climate Control Middle East magazine, V Sekhar Reddy, Managing Director, Lexzander, said the JV, established on November 16, aims to synergise the experience and expertise of the two companies in delivering right solutions at the right time.
The JV’s immediate target is the AED 25-30 million market segment, where it wants to offer a shorter conversion time and optimised resources. Rahul Duragkar, Managing Director, Emitech Group, spoke of a fair shortage of good electromechanical end-to-end solutions.
The JV, he said, aims to give clients more satisfaction than what they are paying for and that it includes offering specialised expertise in engineering and project management. Reddy added: “This association is to add value to the products that need to be delivered, with an emphasis on techno-commercial solutions. We are looking at projects that definitely need personalised attention and, as an outcome, are well-engineered.
The JV aims to work directly with clients on design-build solutions, instead of taking a main contractor approach. Broadly speaking, the scope of work includes mid-size MEP projects, with an emphasis on energy efficiency and good indoor air quality (IAQ), all executed at a low cost per ton. Additionally, the JV aims to serve energy auditing solutions to the market and, further, renewable energy solutions, such as solar heating and associated solar sub devices, including solar PV.
“We come with a combined experience of 62 years and want to address questions arising out of a dearth of qualified MEP contractors,” Reddy said. “I will not hesitate to say that most people are doers, not thinkers. Irrespective of the value of the job, it needs due attention, and for various challenges, companies are not willing to invest in the AED 40 million segment, which takes a good portion of the market and, in the coming years, will form a substantial presence in market development and growth.”
The virtue of ambition
The most environmentally friendly and cheapest energy is that which is not consumed in the first place,” says Thomas Damm, Technical Manager, Sector Department, Air Conditioning and Ventilation Technology, VDMA. This, he says, is why energy efficiency is viewed as key to unlocking the country’s objectives, namely Climate Action Programme’s 2020 interim target of a 40% reduction in greenhouse gas emissions compared to 1990 levels, as well as those under the German National Action Plan on Energy Efficiency (NAPE).
With the building sector accounting for 40% of final energy consumption in Germany, and around one-third of greenhouse gas emissions, Damm says, the sector plays a key role in the country’s comprehensive energy and climate policies. “To this end, the German government has set itself the ambitious goal of achieving an almost climate-neutral building stock by 2050,” he says. “This means that primary energy requirements will be reduced by 80%, compared with 2008.” To achieve this, Damm says, the energy requirement for heating and cooling, as well as for ventilation technology, must be significantly reduced through efficiency measures and the share of renewable energies, in meeting the remaining demand, significantly increased.
With European and national laws impacting air conditioning and ventilation technology, Damm says the challenge for politics and the industry is to decouple CO2 emissions from economic growth. “In Germany, in addition to the Renewable Energy Sources Act (EEG), the German Energy Saving Ordinance (EnEV) is primarily relevant,” he says. “The latter implements Energy Performance of Buildings Directive (EPBD) nationally and defines energy requirements for buildings and the technical building systems and installations contained therein. In addition to air conditioning and ventilation technology, this includes heating technology.”
Citing the September 2018 prohibition of the marketing of high-voltage halogen lamps in the European Union (EU) as an example of the continuous impact political programmes have on technologies’ market viability, Damm highlights the political will in the EU to steer markets toward its environmental agenda. Jens Schuberth, Umweltbundesamt (UBA; The Germany Environment Agency), believes German HVAC manufacturers are
on track when it comes to complying with regulations, due to the time afforded to them prior to the implementation, based on observing new product lines, with features reflecting the new requirements.
Forces driving manufacturers’ compliance
While Schuberth says market compliance is also reflective of Germany’s recognition of EU directives as a member state, Damm adds that voluntary adoption can also be attributed to system operators’ move to cut operating costs. “The continuous increase in the number of central ventilation and air-conditioning units equipped with heat-recovery measures, shows that this can also be done without bans,” Damm says. “Numerous factors can be decisive here — rising energy costs, certification systems for buildings user requirements or financial support measures by the public sector and/or state financial institutions.” Ultimately, Damm says, it is a mixture of instruments, constraints and incentives from stakeholders.
David Miller, Managing Director, Ziehl-Abegg Middle East, provides a manufacturer’s perspective, saying that while, admittedly, the move towards energy-efficient solutions is influenced by political pressure, many customers are also seeing the advantages of investing in such technologies with an eye towards operational savings. “When it comes to design, people are changing their ways,” he says, “which is positive in our point of view.”
Markus-Erich Strohmeier, Senior Executive Vice President, Siemens Building Technologies – Middle East, echoes the need to comply with customer requirements. “When considering cost, we believe it’s important to take into account the lifecycle of the technology and the impact it will have on the efficiency, availability, reliability and operating costs of a customer’s infrastructure during that time,” he says. “Ultimately, we want to ensure that our customers have all the data they need to make an informed choice regarding a product or supplier.”
Bissan Abbas, Managing Director, Techem Energy Services Middle East FZCO, adds that the growing attractiveness of energy-efficient solutions over conventional systems is also driven by rising costs in bigger cities over the years and that compliance with regulations has encouraged stakeholders to thoroughly study ROI to reach a break-even point.
The need for more stringent market surveillance and enhanced efforts towards IAQ
Overall, Damm says that manufacturers view regulations as positive tools for market transformation, towards more efficient products and systems. “It has also been shown in the past that German companies, in particular, with their highly developed products, manufactured with very good quality, have a market advantage — albeit limited in time — over competitors from outside the EU.” This advantage, he stresses, would be even higher if the market surveillance stipulated by the European legislator and given to the EU member states for implementation is carried out.
“However, the system is unfortunately weak and also makes market access possible for products that do not comply with EU law,” Damm says.
Schuberth echoes this, adding that despite energy efficiency inspections on air conditioners having been introduced in Germany as early as 2007, as part of the EU [Energy Performance of Buildings] Directive requirement, this has not been carried out to the extent necessary or expected. The inspections, Schuberth stresses, aimed to identify areas of improvement for building owners, in order to present them with the most economically attractive solution. “Three years ago, Germany started to register all inspections,” he says. “Only one-tenth of the inspections that people expected were carried out. So, there is quite a lack of surveillance and this is a great potential to improve air conditioning and ventilation.”
Another potential area of improvement that Damm believes requires greater attention is IAQ, which, he says, merits the same enthusiasm afforded to energy efficiency. “It is well known and proven that good IAQ is profitable in many ways,” he says, pointing to the indoor comfort in offices, shopping centres and schools, “but currently there are no legal requirements yet related to IAQ in residential and non-residential sectors.
What is there are recommendations from the WHO and the Federal Environment Agency in Germany. However, these are merely recommendations, compliance with which is not mandatory.” Damm says that this is incomprehensible, given that people spend most of their time inside buildings, arguing that much has already been said about the importance of energy efficiency.
Damm stresses that it is important that IAQ and energy efficiency are not considered separately or played off against each other. “The filter industry shows and proves it,” he says. “High-quality air filters enable a higher IAQ, with comparable or lower lifecycle costs over the service life of the filters. And this also applies to higher acquisition costs compared to lower-quality air filters. Improving the efficiency of air filters can help to ensure that IAQ does not remain a stepchild.”
Germany is not sitting on its laurels, as new regulations are underway that could potentially address these gaps. Damm says manufacturers and users are eagerly awaiting the new revision and redesign of legislation for buildings and technical installations, which has been announced by politicians for some time. “Specifically, the existing national legal provisions of the Energy Saving Act (EnEG), the Energy Saving Ordinance (EnEV) and the Renewable Energies Heat Act (EEWärmeG) are to be combined into a new regulation,” he says. “This awaited regulation is called the German Energy Act for Buildings (GEG).”
Schuberth says the lack of market surveillance and inspections could be addressed by the new regulations, recommending more effective controls over the energy performance certificates of the buildings. “There is the idea to have information in the building certificate of existing air conditioners that had to be inspected,” he says. “If the energy performance certificate were to be controlled, they could ask for inspection of air conditioners. It’s quite an indirect way that we hope could have some effect.”
Schuberth says that, additionally, gaps in market surveillance could be addressed by making air conditioners smarter, through the integration of monitoring equipment that detect operational efficiency and report to building owners in the event there are deficiencies. While promising, Schuberth says, this would be mainly applicable to new air conditioners.
Industry 4.0: The inevitability of the Internet of Things
With this recommendation, Schuberth touches on another observable trend in Germany: digitalisation. Citing “Industry 4.0” as the buzzword for 2018 in Germany and Europe, Damm says the advancing digitalisation in production and enhanced communication of devices offers new possibilities towards greater efficiency.
Miller shares a similar observation, reporting that customers are demanding more from their products. “The buzz word is cyber-physical systems,” he says. “Everything speaking to each other and manufacturers offering a lot more feedback that we did in the past.” Miller says this has prompted Ziehl-Abegg to work towards having the capability to connect networks to physical devices, such as sensor fans, frequency inverters and motors, to monitor health and efficiency. “This is an exciting time for us in terms of innovation dictated by our customers and this shift towards energy savings,” he says.
Strohmeier highlights how digitalisation is changing “the way we plan, design, build and operate infrastructure”. He says, “We see technologies, such as augmented reality and virtual reality increasing efficiency over the whole lifecycle of a building. Remote access, maintenance and servicing is gaining increasing relevance, and indoor positioning technology also has the potential to revolutionise the way we manage our infrastructure.”
Strohmeier stresses that Building Information Modeling (BIM) is a key topic that will have significant impact on the HVACR market.
Damm describes BIM as a developing tool for the optimised execution of construction projects. “BIM can and should consider all phases,” he says, “In the best case, BIM accompanies a building or plant from the first stroke of a pen to its demolition.” Damm stresses that through BIM, planning can be done in a cost-effective way to avoid typical building hazards and problems, such as, for example collisions of ducts and tubes, which can be identified early on in the design phase, and addressed by developing and implementing the most suitable solution. He adds that BIM also helps data management to optimise operation and maintenance. “Functioning BIM projects, which are kept up-to-date over the entire period of time, can prevent losses of important information, such as design calculations, design and construction plans or product documentation,” he says. “BIM is a growing system into which all participants must contribute. Anyone who deals with BIM and its possibilities will recognise the opportunities and risks.”
Rolf Werner, Director Application Engineering, Wieland, weighs in, saying that he believes that Germany is, in fact, lagging behind other countries in terms of automation, especially when it comes to BIM. However, Werner commends the platform’s ability to supply necessary data for an integrated process.
Enablers of energy efficiency
While the country still has some way to go, Damm says German companies’ commitment to sustainability has helped paved the way for manufacturers to be technological leaders, globally. “The applicable regulations and their enforcement in the market have a major influence on the use of sustainable technology outside the EU,” he says. “It is clear to see that numerous states in the Middle East are using ordinances and technical regulations as basis for buildings and technical building systems to become increasingly more efficient.”
To underscore his point, Damm says that in the first half of 2018, North Africa and the Middle East accounted for approximately three per cent of air-handling technologies’ total exports. Damm adds that sales of the German air conditioning, ventilation and refrigeration technology industry are expected to grow by a total of five per cent in 2018. Calling German manufacturers, “enablers” in the sector, Damm says, it is only a matter of time before the efficiency wave also reaches farther regions of the world.
