In this paper, we review how indoor air quality has been addressed in case studies of high-performing buildings, specifically the case studies described in ASHRAE's "High Performing Buildings" magazine. We find that nearly all reported case studies of high-performing buildings address energy performance, both in the design and operation of the building. In contrast, while most case studies mention indoor air quality design considerations, they generally do not address IAQ in a comprehensive manner or evaluate the impacts of those design considerations on indoor concentrations or the health, comfort, and productivity of building occupants.
