LBL's IAQ Metrics Development

Lawrence Berkeley National Laboratory is developing in cooperation with others a metric for IAQ in homes. The overall goal is to produce a scoring tool that provides a quantitative measure of a home’s IAQ—an IAQ Metric. The intent is to create a score for the housing unit that provides credit for features that mitigate IAQ hazards and improve the likelihood of good IAQ. The metric defines IAQ hazards as airborne chemical, physical or biological agents, including irritants and allergens that negatively impact health, odor and well-being, and excess moisture at levels that can promote unwanted microbiological growth.
