Initially, the “healthy” part of ASHRAE’s vision meant determining and providing minimum ventilation rates. Over the last few decades, however, indoor air quality research has shown that the ventilation-only approach cannot always achieve the vision because of the diversity of sources and potential contributions of other removal mechanisms. On the other hand, consideration of sources and their impacts can lead to improvements in both health and sustainability. This article covers the evolution from the first paradigm—ventilation rate—to the emerging harm paradigm. Read more
IAQ Paradigms—The Next Generation
By Austin Barolin, P.E., Associate Member ASHRAE; Travis R. English, P.E., Member ASHRAE
The project discussed in this article was completed by a team researching methods to reduce natural gas consumption in hospitals by installing a network of indoor air quality monitoring sensors to monitor how ventilation rates affected air quality and energy. Read more
