ASHRAE celebrates inauguration of global HQ building
ATLANTA, Georgia, 18 November 2021: ASHRAE formally opened its new global headquarters building, following a ribbon-cutting ceremony, attended by its board of directors, top building campaign donors, elected officials and local guests. Making the announcement through a Press release, ASHRAE added that it completed a USD 20 million building renovation project intended to prove the economic viability of a fully net-zero-energy (NZE) operation.
“The completion of this project is an important milestone for ASHRAE as a professional society and for the built environment worldwide,” said Mick Schwedler, 2021-22 ASHRAE President. “Our investments in energy efficiency and sustainability will boost innovation within the built environment and inspire others to replicate our headquarters’ project model. Our Society reimagined a pathway forward for existing building stock and is pleased to provide an example of the future of high performance buildings.”
The renovated, 66,700-square-foot building, situated on 11 acres of land at 180, Technology Parkway in Peachtree Corners, Georgia, is the culmination of a 10-month project, completed in October 2020, during the height of the COVID-19 pandemic, ASHRAE said.
“One could make the assertion that constructing a new net-zero-energy building from the ground up would have been much easier than renovating an existing building,” said Ginger Scoggins, 2021-22 ASHRAE Treasurer and Former Building Ad Hoc Committee Chair. “We decided that ASHRAE could make the greatest impact by showing others how to renovate an existing building with net-zero-energy as the focus, using our own standards and guidelines. ASHRAE is making net-zero-energy the ‘new norm’ in sustainable design and construction. It has been an honor to lead this historic project.”
ASHRAE said the building’s grand opening comes at the conclusion of highly successful building campaign that raised more than USD 10.3 million in monetary donations and contributions of equipment and services from multiple ASHRAE members and 33 corporate donors. Top corporate building donors, NIBE and Cisco, were represented at the ceremony, it added.
“When NIBE was presented with the opportunity to be a part of ASHRAE’s new headquarters, it was an easy decision to play a part in the growth and sustainability of the HVACR industry,” said Eric Lindquist, CEO, NIBE Industrier AB. “Our US brands are focused on continued promotion of systems and solutions that provide comfort, affordability, and betterment of the environment. We look forward to the new headquarters and what the future holds.”
Jeremy Witikko, Office of the Chief Technology Officer, Global Industry Business Strategy, Cisco, said: “When ASHRAE embarked on creating a workspace that reflected their organization’s vision of advancing human well-being through sustainable technology, Cisco was ALL-IN on partnering. Cisco is committed to power an inclusive future for all and were thrilled to be a part of that journey with ASHRAE. Together, let’s continue to build a place where we can meet human needs and protect the planet though technology, our actions, our people and our intentions. An inclusive future starts with a livable planet where people and the environment can thrive together.”
ASHRAE said that although it has occupied the building for more than one year, with limited onsite staff presence, the installation of a Photovoltaic (PV) solar array system was completed in October 2021, marking the beginning of the building’s operation at fully net-zero-energy performance. The PV system is a combination of three sub-arrays, totaling 332kW, mounted on the rooftop and in an unused section of the parking lot, it added.
ASHRAE said that in addition to the PV system, innovative approaches incorporated in the building include:
- Eighteen new skylights and reconfigured window/wall ratio.
- Radiant ceiling panel system: This is used for heating and cooling and dedicated outdoor air system for outdoor air ventilation with enthalpy heat recovery.
- Overhead fresh air distribution system augmented with reversible ceiling fans in the open office areas and displacement distribution in the learning center.
- Six water-source heat pumps (WSHPs): There are four on basement level and two on upper level atrium that will be used to condition these spaces.
- A robust Building Automation System with remote access.
- Demand Control Ventilation (DCV): This will be used for high occupancy spaces in the meeting and learning center.
- On-site electric vehicle charging stations available for guests and staff.
In attendance at the ceremony were representatives from the offices of US Senators Jon Ossoff and Raphael Warnock and Congresswoman Carolyn Bourdeaux, along with county and city officials, ASHRAE said.
“We are very pleased that a professional association of ASHRAE’s distinction selected Peachtree Corners as the site of its global headquarters,” said Mike Mason, Mayor, Peachtree Corners. “Technology Park is a natural fit for an organization whose focus mirrors the city’s efforts in technology innovation, sustainability and green living.”
ASHRAE said its Building Ad Hoc Committee and Technical Advisory Subcommittee, comprising Society volunteers, oversaw the building renovation project. Partners involved in the design, engineering and construction of the building project include: Houser Walker Architecture, McLennan Design, Integral Group, Collins Project Management, Skanska, Shumate Mechanical and Epsten Group, it said. The PV installation was completed by Creative Solar USA, it added.

AMCA initiates work on Standard 340
ARLINGTON HEIGHTS, Illinois, 18 October 2021: Air Movement and Control Association (AMCA) International Inc. is seeking volunteers to serve on the technical committee for a new AMCA Standard: AMCA Standard 340 – Laboratory Method of Sound Testing of Large-Diameter Ceiling Fans.
Making the announcement through a Press release, AMCA said the standard will develop a method of sound testing for large-diameter ceiling fans (LDCF), sometimes referred to as High Volume Low Speed, or HVLS, fans. The method would allow for the third-party certification of sound data in a manner that is cost-effective and produces accurate, repeatable results, and to provide standardized design data for the application of LDCF in occupied spaces, AMCA added.
Currently, each LDCF manufacturer uses a different method of test, AMCA said. Existing sound test standards require acoustical testing chambers that are cost-prohibitive due to the large size of LDCF – up to 24 feet in diameter, AMCA said. A method of test is needed to provide consistent, accurate and comparable sound performance data for designers and end-users, AMCA added.
Committee members would be expected to participate in reviewing the standard and resolving any comments received, AMCA said, adding that meetings will be held virtually by conference call.
According to AMCA, stakeholders for the Standard include manufacturers of LDCF, building design engineers and architects, end-users, testing labs of LDCF, and trade associations and professional societies within the HVAC industry.
AMCA invited those interested in volunteering to click here and complete and submit the form by the close of business on November 17. For more information, it encouraged those interested to contact Shruti Kohli-Bhargava, Manager, Publications & Standards at firstname.lastname@example.org.
STULZ, Mirus, ebm-papst to host webinar on harmonic mitigation in data centres
FREDERICK, Maryland, 26 September 2021: STULZ, Mirus International and ebm-papst will be conducting part 2 of a e-discussion on harmonic mitigation in data centres, STULZ said through a Press release. The webinar is on September 28, the company added.
To improve energy efficiencies in today’s modern custom air handlers, highly efficient electronically commutated (EC) fans are often incorporated for air movement, STULZ said. This is because the fan systems can improve efficiencies over conventional AC motors equipped with variable frequency drives (VFDs) by 30% or more, it said. An EC fan incorporates a brushless DC permanent magnet motor (BLDC) controlled by an integrated rectifier, inverter and smart electronics.
BLDC motors, with efficiencies greater than 90%, provide a more effective ventilation system, so that ‘free cooling’ becomes more easily achievable, which contributes to the energy savings potential, it said. Also, air distribution can be improved with multiple fan arrays allowing upstream or downstream components, such as filters or heat exchangers, to receive a more even airflow, thereby improving air filtering and heat transfer efficiency, it added.
In striving towards reliable and efficient systems, one significant factor sometimes overlooked is electrical harmonic distortion, STULZ said. One of the few things common with AC/VSD and EC fan systems is that they are both harmonic generating, non-linear loads, it said.
Without proper harmonic mitigation, non-linear loads can distort the AC power distribution and possibly expose a mission-critical facility to electrical issues, such as overheating distribution equipment and failure of sensitive equipment connected to the same electrical bus, it added.
The speakers include Dave Meadows, Director of Technology, STULZ USA; Tony Hoevenaars, President and CEO, Mirus International; and Joe Landrette, Director, VAC & Data Centers and Digital Solutions, ebm-papst. According to STULZ, the webinar, scheduled for a 2pm (Eastern Time, US and Canada) start, will be useful to electrical engineers, mechanical engineers and end-users.
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.

Eurovent, FAIAR sign MoU
BRUSSELS, BOGOTÁ, 23 June 2021: Eurovent and the Federation of Ibero-American Air Conditioning and Refrigeration Associations (FAIAR) signed a Memorandum of Understanding, underlining their commitment to greater harmonisation and stronger ties between Europe and Latin America, Eurovent said through a Press release.
In the framework of the Memorandum, Eurovent said, the two organisations will collaborate on standards development, codes of good practice and networking events, among others. Eurovent and FAIAR will have their first high-level coordination meeting still this year to identify concrete opportunities for joint action, Eurovent said.
Raul Corredera Haener, President, Eurovent, said: “In order to raise and harmonise industry standards worldwide, Eurovent’s ambition is to strengthen its international partnerships with like-minded associations. FAIAR has proven to be such a partner, and we look forward to working together with our colleagues from Latin America much more closely in the future to bring new opportunities to our industry.”
Odete de Almeida, President, FAIAR, said: “To achieve FAIAR objectives, we understand the importance of integration of related associations of any territorial scope, in order to provide mutual collaboration and exchange experiences in the professional field, which benefit the partners.”
Eurovent said the two organisations have agreed to work together to promote energy-efficient, environmentally friendly, safe and reliable HVACR technologies based on common principles. The HVACR sector, it added, has an important role to play in the welfare of society and in the fight against climate change. The two regional associations, it further added, aim to avoid disjointed regional approaches to these questions, which would turn opportunities for growth and innovation into market barriers.
HMS launches new IR-based air conditioning interface
HALMS, Sweden, 17 June 2021: HMS Networks has launched an IR-based Intesis AC interface, which the company said enables integration of any air conditioning unit, regardless of brand, into Modbus or BACnet building automation systems.
Saying that HVAC systems are usually the largest consumers of energy in a building, HMS said it is crucial for building owners to monitor and control these systems to save costs and energy. Additionally, the COVID-19 pandemic has made it increasingly important to find new ways of installing and using AC units, as ventilation and “clean air” have become a major concern, the company said. The air conditioning market is growing fast with new brands and different types of AC units constantly emerging, the company said. This, it added, makes it challenging for building owners to integrate AC-units into their specific Building Management System (BMS).
The Intesis offering, the company said, includes the most comprehensive portfolio of AC interfaces on the market, enabling monitoring and control of air conditioning units from any home or building automation system. The portfolio, it claimed, is now further strengthened through the launch of a universal IR-based Intesis AC interface for integrating AC units to Modbus- or BACnet-based automation systems. The new interface connects to the AC unit via the IR link, which is already used by most AC units to communicate with their remote control, it said. The Intesis IR-based AC Interface is already compatible with more than 100 IR remote controllers and their associated AC units, it added.
The new AC interface solution, the company said, is configured using the Intesis MAPS tool, which brings many advantages for the system integrator. With a project-based configuration, all the interfaces installed can be configured in a single MAPS template, making it easy to copy device configurations and set up new projects, it said. Thanks to the diagnostics function, it added, the commissioning process and any post-installation assistance is also simplified.
ASHRAE participates in High Performance Buildings Coalition Congressional Event
ATLANTA, Georgia, 9, June 2021: In recognition of High Performance Building Week, 2020-21 ASHRAE President Charles E Gulledge III, spoke on a panel, titled ‘Building Better: Congressional and Private Sector Efforts to Promote High Performance Buildings’. Congressman, Peter Welch (D-VT), Co-Chair, High Performance Buildings Caucus, and the High Performance Building Coalition organized the event. The Coalition comprises more than 200 manufacturers, trade associations and other stakeholders who support policies and legislation that advance the next generation of buildings.
Joining Gulledge on the panel were chief executives from the International Code Council (ICC), the Green Building Initiative (GBI) and the International Association of Plumbing and Mechanical Officials (IAMPO), ASHRAE said. This was followed by a Q&A session moderated by Lakisha A Woods, CAE, President and CEO, National Institute of Building Sciences (NIBS).
In his remarks, Gulledge spoke from ASHRAE’s current Society theme, ‘The ASHRAE Digital Lighthouse and Industry 4.0’, which focuses on reimaging the building industry, ASHRAE said.
“With the technological transformation of how we design, build, and operate buildings, the lines within the built environment including energy and infrastructure are increasingly blurred,” Gulledge said. “We must think about how existing buildings fit into this transformation. About half of the commercial buildings in the U.S. were constructed more than 35 years ago. Revitalizing these existing buildings represents Congress’s single best opportunity for making a significant impact on sustainability, resiliency, and energy efficiency. ASHRAE is committed to working with Congress to provide resources and knowledge which continually drive the innovative and strategic improvements needed during this transformation of the built environment.”
According to ASHRAE, Gulledge highlighted the new ASHRAE Global Headquarters building to demonstrate how to transform older existing buildings into high-performance workplace environments in a cost-effective and practical way.

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.”
Carel launches pCOe
BRUGINE, Padua, Italy, 22 April 2021: Carel said it has widened its range of I/O expansions in the first part of 2021 with the development of a new digital input expansion board. I/O expansions are modules that can be added to a typical air conditioning application, to increase the number of inputs and outputs available on the controller and, consequently, optimise the flexibility and modularity of the solutions, the company explained through a Press release for the purpose of making the announcement of the launch.
Carel said one of the most common uses of the digital input expansion board involves ventilation sections comprising several fans with electronic motors; in this case, the speed of the individual devices needs to be monitored in order to check their operating status and act on the other fans accordingly, if one of them fails. Carel said it has for many years now offered all of the tools needed to support large systems, such as air-handling units or dry coolers, in which the fans are equipped with electronics that communicate via Modbus®, making it possible to directly monitor their operating status.
However, units that are smaller in size and capacity have simpler and more economical fans that do not feature serial communication and provide a pulse signal based on the rotation speed, which can be read by fast digital inputs, Carel said. This is the basis for the development of its new digital input expansion board, which the company described as an ideal solution for all cases where numerous digital inputs – including fast inputs up to 500 Hz – need to be read, however, while limiting the total number of I/Os and space required, adding only those that are needed.
One typical example involves so-called “in row units” used for cooling data centres. The highly compact units do not require complex device control architecture or specific sensors for their operation, Carel said. These feature a single ventilation section with at least eight fans in parallel, which need to be monitored individually. In this case, reading the signal is a simple and effective way to verify operation, as well as being a more economical solution than installing expensive air flow-rate sensors, Carel said.
The new expansion board, Carel said, features a high number of digital inputs to ensure maximum flexibility in different applications. This is essential on units where the main controller features a limited number of inputs and outputs, while multiple digital inputs need to be connected, for example to detect alarms or various signals.
The entire range of I/O expansions, Carel said, can be integrated into solutions based on the CAREL pCO and c.pCO programmable controller platforms, or into architecture using different controllers.
AHRI, others petition EPA on HFC phase-down rule
ARLINGTON, Virginia, 13 April 2021: The Air Conditioning, Heating, and Refrigeration institute (AHRI) today joined more than 35 other industry and environmental organizations in petitioning the U.S. Environmental Protection Agency (EPA) seeking uniform national standards for stationary air conditioning and commercial refrigeration equipment in the transition to climate-friendly refrigerants under the American Innovation and Manufacturing (AIM) Act. If promulgated, these standards will result in an additional half billion tons of CO2 reduction, over and above what already is projected to be achieved by implementation of the AIM Act, AHRI said through a Press release.
The federal standards sought by the AHRI petition align with similar standards already in place in nine states. The Natural Resources Defense Council (NRDC), the Association of Home Appliance Manufacturers (AHAM), and the Environmental Investigation Agency (EIA) submitted similar petitions under the AIM Act, AHRI pointed out.
For new residential and light-commercial central air conditioning equipment, the petition, AHRI said, seeks a regulation requiring that equipment manufacturers use refrigerants with a global warming potential (GWP) of 750 or less in equipment made after January 1, 2025, with the exception of variable refrigerant flow (VRF) equipment, whose deadline would be January 1, 2026. These transition dates would align the country with the dates adopted in December 2020 by the California Air Resources Board (CARB) and nine additional Climate Alliance states, AHRI said.
For commercial refrigeration and chiller equipment, the petition seeks the GWP limits and transition dates according to the table below:
Through these petitions, AHRI said, a broad variety of stakeholders, including itself, hope to demonstrate that sufficient consensus already exists and that a regular notice and comment rulemaking would adequately represent all material interests, thereby allowing the agency to forego the negotiated rulemaking process it must consider – but is not required to undertake – for such petitions, pursuant to the AIM Act.
AHRI said its petition emphasizes that as a general matter, “the U.S. HVACR industry already is proceeding with the requested transition date as its goal; granting this petition provides order and structure to the market and streamlines industry preparation”.
The transition dates contained in its petition, AHRI said, allow “sufficient time for careful planning and preparation, both to avoid excessive costs that can unduly burden consumers, and to ensure all safety and other associated standards can be met”, according to the petition. “For example, contractors and technicians must receive appropriate training, state and local building codes must be updated and changed, and supply chains and distribution networks must be modified,” AHRI said.
“While AHRI has long believed that an earlier transition would not allow enough time for manufacturers to prepare, we have been equally clear that a later transition date would put long-term compliance with the AIM Act at risk,” said Stephen Yurek, AHRI President & CEO. “Aligning these dates also reduces costs for consumers and ensures long-term availability of energy-, environment-, and life-saving refrigerants for climate control and for the cold chain for food, vaccines, and other medicines.”
AHRI, the U.S. Department of Energy, CARB and other stakeholders have invested more than USD 7 million in research into alternative refrigerants in preparation for this transition, AHRI said, These more climate-friendly alternatives, it added, are in use today in Europe, Australia, Japan, Thailand and in more than 90% of new passenger vehicles currently sold in the United States.
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.

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.

Rubber World Industry launches AED 90mn HVAC production unit
DUBAI, UAE, 21 March 2021: Rubber World Industry, which manufactures and supplies HVAC and MEP products and accessories in the UAE, has launched ‘United Air-Conditioning’, a specialised company with an investment of AED 90 million (approximately USD 25 million), which includes a production plant in Al Jurf industrial area, Ajman, to meet what it described as a growing demand for its environmentally friendly products. Rubber World made the announcement through a Press release.
The new manufacturing unit, spanning over 10,000 square metres, is part of the company’s expansion plans backed by the rising demand for the company’s cooling, heating and now coronavirus-related products, Rubber World said through the Press release. At the onset of the COVID-19 pandemic, the company said it saw a sharp increase in health and environment-related products, such as disinfectant chambers, HVAC filters, air cleaners, optimised HVAC products, and configured rubber insulation and ducts to limit the spread of the virus.
Muzammil Shaikhani, Managing Director, Rubber World Industry, while attributing the new milestone to the company’s customers, said: “I am grateful to our local and international buyers, who have put a strong trust in us, which kept our growth not only intact but rising. In addition, during the pandemic, Rubber World thrived rather than survived and launched United Air Conditioning to cater to the increasing needs of its customers. Our R&D quickly responded to the new demand for health-related products that people and businesses need to maintain health [and] safety and [to] contain the spread of coronavirus and its variants, and started manufacturing this line, which helped doubled our growth and created the need for a specialized production line.”
The new entity, United Air Conditioning will complement Rubber World in manufacturing heating, ventilation, air-conditioning, cooling, mechanical, electrical and plumbing products, parts and accessories for commercial and residential use in the UAE, Rubber World said. United Air Conditioning will focus on health and environment-related products, modified HVAC and MEP parts, such as rubber insulation and ducting lines, which have become essential in the current environment, Rubber World said. It will help in reducing emissions, improve energy efficiency and contribute to the climate change agenda, it added. Rubber World has two units in the UAE and one in Sri Lanka. The company said it plans to set up six new production facilities in South Asia and the Middle East in the next three years to cater to the needs of its growing customer base.
Rubber World said that United Air-Conditioning has helped it increase its range of products, such as cooler tubes and sheets, which are CFC-free and are designed for exposed pipe area, as commonly seen in supermarkets, hospitals and schools. Another key area of demand for United Air-Conditioning’s products is all types of flexible ducts and ducting accessories with a broad range of adhesive tapes, Rubber World said. Rubber World said it currently serves several customers, including Leminar Air Conditioning Company, Century Mechanical Systems Factory, Gulf-O-Flex AC Spare Parts Trading, Gmark Middle East FZC and Al Emadi Air Conditioning & Refrigeration Equipment.
‘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.

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.”
ASHRAE releases core recommendations for reducing airborne infectious aerosol exposure
ATLANTA, Georgia, 14 January 2021: The ASHRAE Epidemic Task Force has released new guidance to address control of airborne infectious aerosol exposure and recommendations for communities of faith buildings, ASHRAE said through a Press release.
An infectious aerosol is a suspension in air of fine particles or droplets containing pathogens, such as the SARS-CoV-2 virus, which can cause infections when inhaled, ASHRAE said. They can be produced by breathing, talking, sneezing and other as well as by flushing toilets and by certain medical and dental procedures, it added.
ASHRAE’s Core Recommendations for Reducing Airborne Infectious Aerosol Exposure concisely summarize the main points found in the detailed guidance documents produced by the ASHRAE Epidemic Task Force, it said. They are based on the concept that ventilation, filtration and air cleaners can be combined flexibly to achieve exposure reduction goals, subject to constraints that may include comfort, energy use and costs, it added.
“This guidance outlines a clear approach for lessening the risk of infectious aerosol exposure for building occupants that can be applied in a wide range of applications, from homes to offices, to mobile environments, such as vehicles and ships,” said William Bahnfleth, Chair, ASHRAE Epidemic Task Force. “ASHRAE’s Core Recommendations are based on an equivalent clean air supply approach that allows the effects of filters, air cleaners, and other removal mechanisms to be added together to achieve an exposure reduction target.”
According to ASHRAE, specific recommendations include the following:
- Public health guidance
- Follow all regulatory and statutory requirements and recommendations.
- Ventilation, filtration, air cleaning
- Outdoor airflow rates guidance for ventilation, as specified by applicable codes and standards.
- Recommendations on filters and air cleaners that achieve MERV 13 or better levels of performance.
- The use of air cleaners.
- Control options that provide desired exposure reduction while minimizing associated energy penalties.
- Air distribution.
- Promote the mixing of space air.
- HVAC system operation
- Maintain temperature and humidity design set points.
- Maintain equivalent clean air supply required for design occupancy.
- Operate systems for a time required to achieve three air changes of equivalent clean air supply.
- Limit re-entry of contaminated air.
- System commissioning
- Verify that HVAC systems are functioning as designed.
According to ASHRAE, the task force’s Communities of Faith Buildings guidance offers recommendations on conducting worship services under epidemic conditions.
Rick Karg, ASHRAE Epidemic Task Force member, said: “The intent of the Communities of Faith guidance is to offer those who operate and care for buildings used for worship a plan for implementing short- and long-term HVAC strategies to reduce the possibilities of transmission of the SARS-CoV2-2 virus. The document also helps communities move toward a new ‘normal’ operation after this public health emergency nears an end.”
According to ASHRAE, recommendations for Communities of Faith include the following:
- Identify HVAC system characteristics. Compile and review operation and maintenance manuals and schedules.
- Verify HVAC systems are well maintained and operating as intended. For maintenance, follow the requirements of ASHRAE Standard 180 – 2018, Standard Practice for the Inspection and Maintenance of Commercial HVAC Systems.
- Consider PPE when maintaining HVAC systems, including filters, coils and drain pans.
- Operate HVAC systems, if present, with system fan set to run continuously when building is occupied for services or cleaning.
- Operate the system for a time required to achieve three equivalent air changes of outdoor air (effect of outdoor air, filtration and air cleaners) before the first daily occupancy and between occupied periods, if appropriate. Three equivalent air changes can be calculated using ASHRAE’s Building Readiness Guide.

Kingspan Insulation launches product for external ductwork applications
DUBAI, UAE, 5 January 2021: Kingspan Insulation launched the KDuct, which the company described in a Press release as catering to external ductwork applications.
According to the company, the KDuct incorporates its pre-clad ductwork system, made of thermoset, fibre-free pre-insulated duct board with a heavy-duty outer jacket. The company described the product as ideal for external applications, plantrooms, risers, congested spaces and lightweight specifications. The KDuct, Kingspan claimed, offers high performance, rigid, closed-cell insulation core, manufactured with a blowing agent with zero Ozone Depleting Potential (ODP) and low Global Warming Potential (GWP). At the same time, it said, the panels are faced on both sides with an embossed aluminium foil. The new product line would provide ultra-strength and rigidness; cost-savings over traditional exterior ductwork; extra-low air leakage, which does not allow conditioned air to escape; and high-compressive strength, among several other benefits, the company said.
Sarmad Fakhri, Managing Director, Kingspan Insulation, said, “KDuct Ductwork system would help our customers to save extra cost and time due to its lightweight and single-fix properties.” Unlike the traditional approach to ductwork construction, which requires sections to be lagged with insulation, once installed, the KDuct panels are pre-insulated with a high-performance insulation core, the company said. This single-fix and lightweight design, the company added, reduces installation time and transfers the cost benefits to the building owners.
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.

Biomimicry profiling reduces CO2 consumption
Kuenzelsau, Baden-Wurttemberg, Germany, 21 March 2019: Ziehl-Abegg said through a Press communiqué that it is further utilising biomimicry in a bid to bolster its efforts towards mitigating climate change. To further reduce CO2 consumption, the company said through the communiqué, the humpback whale served as the model for the latest composite material fan development, which also incorporates biomimicry features of owls and trees. This improves the carbon footprint equally in two ways – through a significant reduction in the material used as well lower energy consumption, when operating in climate control equipment and industrial ventilation systems.
Ziehl-Abegg, the communiqué said, is already at more than 70% peak efficiency with its centrifugal fans, so every opportunity for the optimisation of performance must be utilised. The new centrifugal impeller possesses features of three completely different approaches to Biomimicry: from both aerodynamics (ornithology) and hydrodynamics (marine biology) and biomechanics (trees), the communiqué said. Savings in material content and improved aerodynamics halve CO2 emissions associated with manufacturing, whilst maintaining the same ventilation performance, the communiqué added. Modern injection-moulding tools, each costing more than half a million euros, enable the company to implement the geometries, which have been optimised through the application of Biomimicry, the communiqué further added.
According to the communiqué, the trailing edges of the fan blades are modelled on the owl wing. “As the quietest bird of prey, the owl has already been used as a role model for several designs,” said Peter Fenkl, CEO. Serrated trailing edges of fans are now seen as a trademark of Ziehl-Abegg. In the new fan however, the design of the serrations was a little smoother, the communiqué said.
Evolution has optimised the flow efficiency of the humpback whale overall in such a way that, despite its body size, it is considered a very good and agile swimmer. If this had not been the case, it would also have been unable to make its long journeys through the world’s oceans without having to feed. The latest generation of centrifugal fans at Ziehl-Abegg is now benefitting from this knowledge of biomimicry, the communiqué said.
The developers at Ziehl-Abegg, the communiqué said, also drew inspiration from Professor Claus Mattheck. The “tree whisperer” or “tree pope”, “as the media call him, creates a bridge between nature and technology. The professor is, after all, a pioneer of the science of biomechanics. Trees are a prime example of optimum strength with minimum use of materials. The five blades of the centrifugal ZAbluefin fan, the communiqué said, merge into both the cover and back plate in exactly the same way as trees grow upwards – at a slight radius to the ground. This is scarcely visible with the naked eye, because the curves, which mimic a tree, are minimal. Nevertheless, these bionic approaches in the blade transition provide the same strength as heavy wings – enabling the use of materials to be significantly reduced. Less material consumption in production also means a lower carbon footprint, the communiqué said.
According to the communiqué, the air flow in centrifugal fans hits the fan blades at different angles, depending on the volume flow. The whale has to overcome similar challenges when swimming in the sea – the movement of the fins causes their angular position to constantly change. If its pectoral fins were to be positioned at too steep an angle to the opposing current, strong turbulence would result in the water separating from the fins. “High flow losses and noise are characteristic features of strong turbulence,” said Dr Walter Angelis, Technical Director, Ziehl-Abegg. The design of the fins on a humpback whale has been optimised over millions of years. That’s why the leading edges of the whale fins contain golf ball-sized nodules (technical term: tubercle). This allows an animal weighing 25 to 30 tonnes to swim very quickly and nimbly using its long pectoral fins. “We recreated this aspect at the leading edge of the fan blades and implemented it in the form of a rippled surface,” Angelis said.
The flow engineers also took a closer look at the whale’s tail fin, the “fluke”, the communiqué said. The V-shaped contour of the tail fin section, the communiqué said, delays any potential flow separation – which enables the fan to be used for numerous pressure ranges. The latest generation of centrifugal fans at Ziehl-Abegg, the communiqué said, is now benefitting from this knowledge of biomimicry.
