Indoor Air Quality (IAQ)

Indoor Air Quality (IAQ) refers to the quality of the air within a space. A space with good indoor air quality is one that is well ventilated (with outside air) and that is not compromised by pollutants brought into the space or by pollutants off-gassed within the space. Strategies used to create good IAQ include bringing in 100% outside air, maintaining appropriate exhaust systems, complying with ASHRAE Standard 62.1, utilizing high efficiency MERV filters in the heating ventilation and air conditioning (HVAC) system, installing walk-off mats at entryways, prohibiting smoking with the space and near operable windows and air intakes, providing indoor plants, and using only low-emitting / non-toxic materials and green housekeeping products.
