Map of the western United States with the marine and hot-dry / mixed-dry climate zones marked.

Project Objective

This project entails the measurement of time-integrated concentrations and temporal profiles of humidity and established contaminants of concern in a minimum of 64 new homes located in cold and marine climate zones.

Specific objectives:

  • Measure time-integrated concentrations and temporal profiles of humidity and established contaminants of concern, monitor the use of ventilation equipment, and track activities that impact air pollutant emissions and removal processes in typical homes in various climate zones.
  • Characterize the prevalence, type, and installed performance of mechanical ventilation equipment in new homes; explore regional variations in system designs and performance.
  • Investigate associations of indoor humidity and contaminant levels with the presence of control measures including (ASHRAE)-62.2 compliant mechanical ventilation, envelope airtightness, mechanical system commissioning, and potentially low-emitting materials.

Project Impact

Results will enable associations of indoor humidity and contaminant levels with the presence of control measures including American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 62.2 compliant mechanical ventilation and envelope airtightness.
