All buildings are dynamic, spatially heterogeneous, and far from inert. Recent trends in building construction, operation and maintenance, and the behavior and choices of human occupants, have magnified the importance of physical, chemical and biological reactions in buildings. These reactions lead to a wide range of contaminants that were rare in buildings just two decades ago. Such contaminants may persist for days to decades, serve as respiratory irritants or triggers for asthma, and can be toxic.
This presentation will involve an exploration of the ingredients that magnify the reactivity of buildings, as well as passive engineering solutions to adverse reactions that should foster greater human health within the sustainable building movement.
