Indoor Air Quality in Sustainable, Energy Efficient Buildings



Andrew K. Persily, Steven J. Emmerich


Building designers, contractors, owners and managers have long been challenged with providing quality indoor environments at a reasonable energy cost. Current efforts to improve building energy efficiency, including goals of netzero energy use, are bringing more focus on how to simultaneously achieve energy efficiency and indoor air quality (IAQ). While energy efficiency and IAQ are sometimes viewed as incompatible, there are in fact many strategies than can achieve both ends. This paper discusses the relationship between IAQ and energy efficiency, primarily in terms of the impacts of ventilation. A number of strategies that are currently being used or proposed to provide both improved IAQ and energy efficiency are highlighted including increased envelope airtightness, heat recovery ventilation, demand controlled ventilation, enhanced particle filtration, and improved system maintenance. In addition, the manner in which various green building and sustainable building programs, standards and guides address IAQ is reviewed. These programs and documents are driving the move towards sustainable buildings, and the manner in which they consider IAQ is critical to achieving energy efficient buildings with good indoor environments.
