What is "Indoor Air Quality" and how is it assessed in PBRS?

Indoor Air Quality (IAQ) refers to the condition of the air inside buildings, which can significantly impact the health and comfort of occupants. In the context of the Pearl Building Rating System (PBRS), IAQ is assessed primarily through the evaluation of ventilation strategies and the emissions of materials used within the building.

When assessing IAQ, the system emphasizes the importance of proper ventilation to ensure that fresh air is circulated and pollutants are minimized. Additionally, it considers the materials utilized in construction and furnishings, as these can release volatile organic compounds (VOCs) and other harmful substances that can deteriorate air quality. Therefore, the assessment focuses on quantifiable measures such as air exchange rates, types of air pollutants, and the potential impact of building materials on overall indoor environments.

The other choices do not accurately capture the comprehensive criteria used to assess indoor air quality within PBRS. While outdoor air quality, heating and cooling systems, and occupant feedback may influence overall environmental conditions, they do not constitute the main elements of IAQ assessment as outlined in PBRS.
