When thinking about Green Building certification, it’s important to factor in the indoor environment and air quality. Indoor Environmental Quality (IEQ)/Indoor Air Quality (IAQ) are the conditions inside a building—air quality, lighting, thermal conditions, ergonomics—and their effects on occupants. Several Green Building programs emphasize IEQ/IAQ through building design considerations and therefore tend to have better indoor air quality than conventional buildings. Why is this important? Addressing IEQ/ IAQ has a positive impact on the overall human health of its occupants and can lead to an improved quality of life, less stress, and can reduce the risk of potential injuries. Here is a helpful guide to the Indoor Environmental Quality (IEQ)/Indoor Air Quality (IAQ) sections of LEED, WELL, BREEAM, and Living Building Challenge programs.
Regardless of your role in the entire certification process, you need to know the specific certifying agency, version, building type, and any additional credits the program is seeking to obtain; this will be especially helpful for the laboratory assisting with the data needs. You will see below that there are many different configurations of the IEQ/IAQ credit sections. Of these, TVOC, Formaldehyde, Ozone, PM 2.5, PM 10, and Carbon Monoxide are the most common requirements.
