Research Areas


Multiple indoor conditions converge to shape occupant comfort and satisfaction, including artificial and natural lighting, air quality, acoustics, thermal comfort, and functional aspects such as the sense of privacy and personal space. My research has effectively isolated and explored each IEQ dimension both separately and in combination to develop a holistic approach that contributes to a growing body of knowledge.

Programs to enhance the sustainability of building infrastructure often require prioritizing multiple objectives to maximize environmental and economic benefits. Energy Conservation Opportunities (ECOs) within the existing buildings provide better prospects to lower greenhouse gas emissions than for new energy-efficient buildings. My research aims to deliver a scalable decision-making framework for building managers seeking to improve energy efficiency while respecting occupant comfort criteria.

Finally, tradeoffs between energy use and comfort has to be considered. For example, an increase in energy cost has traditionally resulted in a tighter building envelope and decreased air change rates. However, poor indoor air quality puts more than 40% of the US population at risk for serious respiratory and cardiovascular diseases. Improving indoor air quality, which frequently calls for increased ventilation, filtration, and portable air cleaners can add energy burdens that conflict with building energy-saving guidelines. Therefore, my interest lies in systematically assessing the effectiveness of interconnected, sustainable strategies while alleviating environmental burdens.
