The D-A-CH group (D \u2013 Germany, A \u2013 Austria, CH \u2013 Switzerland) of HVAC experts has been meeting every autumn since 2010 to exchange knowledge and insights. This year\u2019s conference took place on 8\u20139 October in Lustenau, Austria, bringing together 33 professionals from Germany, Austria, and Switzerland. The main topic was comfort ventilation<\/strong> and its essential role in ensuring healthy indoor air. After all, clean air is a basic human right.<\/p>\n

As a company committed to improving air quality, Marquis Intelligence considers it its responsibility to keep the community informed about new developments and significant professional initiatives in the field of comfort ventilation and air purification \u2013 including\u00a0this conference.<\/p>\n

Why? For Marquis Intelligence, turnkey comfort ventilation for homes and apartments<\/strong> is a cornerstone of its business. Through tailored air purification aligned with user needs and preferences, Marquis Intelligence delivers optimal indoor air quality combined with energy efficiency.<\/p>\n

Why is Indoor Air Quality a Central Topic?<\/strong><\/h2>\n

Globally, more and more attention is given to outdoor air pollution.
\nThe World Health Organization warns that only a small fraction of the world\u2019s population lives in areas where the air is considered safe to breathe.
\nMost people inhale polluted air every day.<\/p>\n

According to the U.S. Environmental Protection Agency (EPA), indoor air is often two to five times more polluted<\/strong> than outdoor air.<\/p>\n

It is therefore unsurprising that the D-A-CH conference focused on indoor air quality <\/strong>and the role of comfort ventilation in achieving it.<\/p>\n

Outdated Standards: A Harvard Example<\/strong><\/h2>\n

At a panel held last year at Harvard University, Professor Joseph Allen highlighted the severe obsolescence of existing regulations. The current U.S. Occupational Safety and Health Administration (OSHA<\/a>) standard still allows particulate matter concentrations of up to 5,000 \u00b5g\/m\u00b3 in workplaces. That is approximately 500 times higher than the 9 \u00b5g\/m\u00b3 limit set by the EPA for PM2.5 particles in outdoor air.<\/p>\n

This example clearly shows that many countries’ existing indoor air quality standards are outdated and inadequate<\/strong>. Redefining them in line with modern scientific understanding is therefore essential.<\/p>\n

Technologies for comfort ventilation and air purification already exist. However, current regulations do not mandate their use. In other words, we have the solutions but not the obligation to implement them.<\/p>\n

Topics of the D-A-CH 2025 Meeting<\/strong><\/h2>\n

Over the two-day conference, a wide range of topics were discussed. Here are some of them:<\/p>\n
