Abstract
We spend 90 % of our lives indoors [1], inhaling more air (by mass) than we consume water! In contrast to outdoor air pollution levels, which are regulated, existing standards for the control of indoor air pollutants consist largely of prescriptive design requirements rather than operational performance limits [2,3]. The World Health Organization states that air pollution is the second highest risk factor for noncommunicable diseases [4]. Because we spend so much time indoors, outdoor air pollution that enters indoor environments presents an important exposure hazard that can be compounded by emissions from indoor sources of airborne contaminants – yet we don't routinely monitor indoor air quality. In this column, we'll explore the past, present and future of building monitoring, which ties in with "Healthy Buildings: Designing for Life," the theme of 2025 – 26 ASHRAE President Bill McQuade, Fellow ASHRAE.Citation
