The Healthy, Efficient, New Gas Home project is studying ventilation and IAQ in California homes constructed since the 2008 building code came into effect. The collected data include characteristics of ventilation equipment, their performance, and their usage; occupant activities that impact IAQ; perceptions of IAQ and comfort (via a survey); and measurements of IAQ (formaldehyde, CO2, humidity, PM2.5, and NO2) over one week. This session will present the results of our field study; the summary of ventilation system performance, impacts of occupant activities on IAQ (effects of cooking and range hood use on PM2.5 and NO2 concentrations; the relationship between estimated ventilation rates and indoor formaldehyde concentrations), and a summary of the occupant survey.
