Ventilation and Indoor Air Quality in New US Homes: Preliminary Observations from a Building America
Energy-efficient new homes that are built tight require appropriately sized bath and kitchen exhaust and whole house mechanical ventilation (WHMV) systems to enable good indoor air quality. ASHRAE Standard 62.2 specifies minimum airflow rates and requires verification, but there is a lack of data on installed system performance and operation and their relationship to indoor air quality in occupied homes. This session will present early findings from an ongoing Building America research study that has gathered data on mechanical ventilation systems, indoor air quality parameters, and house and household characteristics from 180+ occupied homes in CA, CO, FL, GA, IL, OR, and SC.
