01. Air quality standards
To ensure a basic level of high indoor air quality.
Pollutants generated indoors can lead to a variety of symptoms and health conditions. Volatile organic compounds (VOCs), combustion byproducts and airborne particulate matter are known to trigger nausea, headaches, asthma, respiratory irritation and allergies. While ambient outdoor air is often better quality, natural ventilation methods, operable doors and windows, and general building envelope infiltration can diminish indoor air quality if external air quality parameters are poor.
The following conditions are met:
The following conditions are met:
The following conditions are met in projects with regularly occupied spaces at or below grade:
The following air quality concentrations are met in the commercial kitchen space:
