Camfil highlights the value of the World IEQ Forum 2022

STOCKHOLM, Sweden, 27 June 2022: One way to protect people from air pollution is to provide clean and healthy air inside of buildings, Camfil said through a Press release, dated June 27. This was the main conclusion at the 6th edition of the World IEQ Forum, held on March 16, in the Sweden Pavilion at the World Expo in Dubai, Camfil added.

The Expo may have concluded, but the topic of Indoor Air Quality (IAQ) still remains a mainstream concern that is discussed globally, Camfil said, adding that there were two reasons for the 2022 World IEQ Forum having had an extra focus on IAQ:

  • According to the World Health Organisation (WHO), the risk of spreading the COVID-19 virus between people is higher in poorly ventilated indoor settings.
  • In September 2021, WHO published the first new version of their global Air Quality Guidelines since 2005.

“New scientific studies place the threshold of air pollution exposure considered harmful to human health 50% lower today compared to 17 years ago, when the previous WHO Air Quality Guidelines were published”, said Tobias Zimmer, Camfil’s Vice President of Global Product Management & International Standards. Tobias was a speaker and panellist at the World IEQ Forum.

Further, a recent WHO study states that 99% of the world’s population lives in areas with too much air pollution, Camfil pointed out. Air pollution that is causing serious human suffering in the form of diseases and millions of premature global deaths yearly and, on top of that, substantial economic costs, Camfil added.

“In the North African and Middle Eastern regions, air pollution is responsible for 270,000 deaths every year at a cost of 141 billion US Dollars, according to the World Bank”, Zimmer said. He went on to point out that most people today spend 90% of their time indoors and that the simplest and best way to achieve protection against harmful airborne particles is to invest in efficient air filtration solutions across all buildings.

“The need for quality air filtration is reflected via the much lower PM2.5 and PM10 threshold levels stated in WHO’s new Air Quality Guidelines,” Zimmer said. “These thresholds also align with Eurovent Guideline 4/23 for the selection of EN ISO 16890-rated air filter classes for general ventilation applications.”

At the same time, Zimmer was careful to emphasise that it is not possible to have a same-solution-fits-all approach to cleaning the indoor air. “Consensus at the World IEQ Forum was that every solution has to be tailored to where the building is located,” he said. “The outside air quality must determine the solution you have inside.” For example, he added, what works in a temperate zone might not be right in regions with high humidity. “The needs can also vary within a region,” he said. “Cities are more afflicted when it comes to air pollution than the countryside. Some cities are more polluted than others.”

According to Camfil, the World IEQ Forum is an opportunity for experts on IAQ, like Zimmer and his colleagues, to engage with, for example, representatives from the Ministry of Health and other influential representatives from various countries. “It is imperative that we continue to raise awareness around the urgent need to protect people from air pollution,” Zimmer said. “When you look at the human and financial costs on a global level, it is evident that we can’t afford not to protect ourselves.”

Zimmer said participants at the World IEQ Forum did not just talk about the importance of healthy IAQ. “We also demonstrated proof of concept by measuring the outside and inside air at the location during the EXPO,” Zimmer said. “Dubai’s outdoor air was 10 times more polluted than the WHO recommendations. The air inside the air-filtrated Sweden Pavilion was well below WHO limits for particle concentration.”

Zimmer said the effect of the clean indoor air in the Sweden Pavilion was visible to the naked eye. “After several hours of listening to me and other speakers, the audience was still fresh and alert,” he said. “So, you could say that we certainly ‘walked the talk’ when it comes to proving the benefits of clean, healthy and productive indoor air.”

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.
