Abstract
Poor air quality is considered to be one of the leading causes of global non-communicable disease and mortality. People in the United States spend 87% of their time in enclosed buildings and 69% of that time is spent in their residence. A building's envelope filters pollutants, such as particulate matter (PM) and ozone (O3), as air infiltrates into a building. The indoor environment is also directly affected by indoor sources due to outgassing from indoor materials or due to activities of the occupants such as cooking or cleaning. The outdoor environment around a building is in a constant state of change due to the diurnal cycle caused by solar radiation and on longer time scales caused by changing weather and climate. Therefore, it is important to understand the impacts that could arise from a changing climate. The CONTAM computer model is used to simulate indoor air quality of both fine-scale temporal measured test homes as well as representative U.S. building stock homes. It was found that CONTAM can closely simulate fine-scale temporal measured homes mean concentrations. The process and methodology used from the EPA STAR test homes was applied to simulate representative U.S. building stock homes from three 10-year periods centered on 2000, 2050 and 2090. It was found that the impacts due to climate change on IAQ are very location and home dependent, but tight homes with controllable outdoor air supply system have more to mitigate the effects.
