‘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.
LightAir says subscription strategy is yielding results
STOCKHOLM, Sweden, 12 June 2021: LightAir said its strategic focus on sales of air purification to offices and schools in Sweden is continuing to yield results. The LightAir Health+ offer provides clean, virus-free air and is offered in Sweden primarily as a subscription service, it said, adding that the number of subscriptions is growing continuously, rising from about 60, last summer, and soon likely to exceed 300.
The positive market reception in Sweden is exemplified by how Enskilda Gymnasiet – an independent secondary school in operation for over 100 years – is now expanding its two subscriptions to 30, LightAir said. The school carried out a six-month evaluation, which documented how individuals with asthma and allergies experienced relief from problems and that other students and teachers experienced improved air quality, LightAir said. Evaluation comments mentioned reduced fatigue, improved concentration and less drowsiness, it added.
“We are located in central Stockholm and are aware that we operate in an environment that is particularly exposed to traffic pollution,” said Jonas Persson, Project Manager, Enskilda Gymnasiet. “It’s important that students can stay healthy, cope with the school day and don’t get fatigued by bad air. It’s especially important that they are alert when final exams roll around. Students with pollen allergies are prone to tire easily and perform poorly.”
According to LightAir, Enskilda Gymnasiet is now installing a total air purification capacity of over 20,000 cubic metres per hour, along with a corresponding virus inhibitor capacity. Subsequent to the sale of the purifiers, the service will be delivered in the form of a three-year subscription, LightAir said.
According to LightAir, its Health+ subscription offer is the most comprehensive service offer available and was established in the Swedish domestic market in 2020. The offer has since been awarded the International Facility Management Association’s Nordic Innovation Prize, not least since it has the distinction of being able to destroy viruses while they’re still airborne, the company said.
“More and more businesses and organizations are opening their eyes to the challenges of indoor air,” said Joakim Hansson, Business Area Manager, LightAir. “This is also shown concretely by how we expanded our subscription base from 5 to 60 last summer, and from 60 to 160 by year end. This summer we have high hopes of reaching our goal of 300 Swedish subscriptions.”
Added Lars Liljeholm, CEO, LightAir: “We see that our strategic plan is promising and starting to bear fruit, while we have a long way to go with stimulating challenges ahead of us. We will become increasingly better at utilizing the competitive advantages we have in the nascent corporate market, not least in terms of purification efficiency and noise levels, as well as with an attractive and trouble-free subscription offer. Professional solutions will be the engine of our future growth. Through an increasingly successful domestic market, we are laying the foundation for establishment in selected international markets.
“We are in the middle of the demanding – but enjoyable – work of building a leading position in the commercial segment. Initially, the new strategy will affect sales when we change our revenue model, but in the long run, this will be crucial for the company and value creation for our owners. With that said, the consumer market will still be an important part of the future LightAir we are now building, which is why we have also recruited cutting-edge expertise and are continuously developing our international ventures and e-commerce.”
‘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.

Future of HVAC in India is bright, says Magneto Clean Tech
New Delhi, India, 18 June 2019: The HVAC industry in India has immense potential but is heavily dependent on the economic activity around the building industry, said Himanshu Agarwal, CEO, and Founder, Magneto Clean Tech, while providing an overview on the HVAC market in India. In the last few years, heavy debt has propelled the industry to undergo a restructuring, which has led to excessive competition and a price war, he said. From a broad perspective, Agarwal said, air pollution in India is high and the awareness regarding the bad air quality is a subject that is given more attention every day. This he said, will lead to high demand for air systems.
Elaborating on Magneto Clean Tech, a New Delhi-based HVAC company, Agarwal said: “Magneto Clean Tech invents and popularises clean air technology for developing nations. We focus on making clean air accessible to everyone, whether in homes, in the office or in buildings.” By pushing the limits of engineering, he said, we are able to build the highest quality of products that exhibit performance. While providing an overview of the work done in the year 2018, he said, we delivered clean air to a total area of 2.5 million square feet. “The year 2019, Agarwal said, looks bright as the company’s projected growth rate is over 100%.
Magneto Clean Tech’s products, he said, have energy-saving benefits due to a very low-pressure drop in the air conditioner. They clean the air holistically, removing dust, micro-organisms and even harmful gases, he said. “We have successfully commercialised a proprietary way of purifying indoor air that is fundamentally superior to current methods,” he said. In addition, Agarwal highlighted that the company has a diverse range of air-purification products that deals with PM 2.5, along with infection control, which as a technology, is being received with an overwhelmingly positive response from users.
