Resilience is a critical goal for buildings, particularly in the face of recent flods, tornadoes, and earthquakes. For occupants of a building, the indoor environment is expected to provide thermally comfortable conditions and to limit the concentrations airborne contaminants to safe and comfortable levels. The indoor enviroment, primarily via building enclosure, is also intended to isolate the building occupants from the exterior environment, such as precipitation, pests and threats to physical security. And it provides amenities such as light, power and food storage.
Indoor environmental quality (IEQ) assume the role of protecting against and be resilient towards: extreme weather and increased frequency of heat waves, heavy downpours, floods and hurricanes, wildfire smoke, increased levels of pollen and impacts on asthama and allergies. Several problematic indoor exposures include: indoor contaminants, dampness, moisture and flooding, infectious agents and pests, thermal stress, and building ventilation, weatherization and energy use.
