• Characterization of indoor air quality and effect of whole house mechanical ventilation in new homes in the southeast U.S. (Funded by US DOE Building America Program)
• Conducted meteorological and air quality measurement of PM2.5, ultrafine particles, radon, SVOCs, formaldehyde, CO2, and NOx using a suite of monitoring devices including photometric, filter-based, and passive sampling.
• Performed building air flow, airtightness, duct leakage tests using tracer gas and deltaQ methods.
• Evaluated performance of whole-house mechanical ventilation (WHV) including energy recovery ventilator (ERV), central fan integrated system (CFIS)/runtime vent, exhaust, etc. and their compliance with ASHRAE 62.2 in.
