The Healthy Efficient New Gas Homes (HENGH) study is gathering field data from new California homes that use natural gas and are built to 2008 Title 24 standards. Mechanical ventilation is required, so that the reduction in air infiltration and duct leakage needed to save energy will not result in negative health impacts due to decreased dilution of indoor pollutants with outdoor air. This presentation describes results from two research efforts leading to the field study: (1) an online survey with questions about ventilation and IAQ, and (2) a pilot test in two new homes that have mechanical ventilation.

Balancing IAQ and energy savings in exhaust systems have a direct relationship in multifamily high rise buildings. Since there has been little attention on the quality construction of exhaust systems, retrofitting them for current compliance in today's environment can not be done without a baseline of field conditions . This program focuses on the real world challenges, issues and approaches to a key component of multi-family buildings often overlooked.

The Population Impact Assessment Modeling Framework (PIAMF) was developed to quantify the energy and health impacts of changes to the U.S. housing stock. PIAMF calculates one or more environmental and energy performance parameters for each home in a sample of 50,000 homes representing the U.S. housing stock. This presentation gives an overview on applications of PIAMF to develop guidance for cost-effective, energy-efficient methods to reduce indoor exposure to PM2.5. Previous applications have assessed the energy impacts of range hood use, building tightening for the U.S. housing stock, and the exposure impacts of natural gas cooking in Southern California.

We evaluated nine combinations of ventilation and air cleaning systems for pollutant removal and energy use. Systems included supply, exhaust, and balanced ventilation; filtration on ventilation supply and on recirculating FAU; filters with varying MERV ratings; and three VOC air cleaning technologies. All were installed in an unoccupied 2006 house located 250m downwind of I80 in Sacramento, and evaluated for effectiveness at reducing outdoor particles in summer and fall/winter, ozone and VOCs in summer, and indoor particles generated from cooking. Energy use of the systems was estimated for year-round operation in varied California climates.
