Dr. Wanyu (Rengie) Chan is a Research Scientist and Deputy Indoor Environment Group Leader in Energy Analysis and Environmental Impact Division at Lawrence Berkeley National Laboratory. Her work focus on characterizing indoor air quality and implications to human exposures in residential and commercial buildings. She led a recently completed field study to evaluate the role of mechanical ventilation on indoor air quality in 70+ new California homes. The project was funded by California Energy Commission (CEC), involving multiple collaborators including two California’s Investor Owned Utilities. Dr. Chan is part of an ongoing project funded by Department of Energy, Building America Program to study indoor air quality in new homes across different U.S. regions. Dr. Chan has ongoing research studying indoor air quality and ventilation in California classrooms, working in collaboration with UC Davis Western Cooling Efficiency Center. She was the co-PI of Healthy Zero Energy Buildings project that aimed to inform commercial building ventilation standards, balancing energy efficiency objectives and the need to maintain acceptable indoor air quality. Dr. Chan joined the Laboratory as a graduate student and worked on the evaluation of shelter-in-place effectiveness. She collaborated with the National Atmospheric Release Advisory Center to develop an operational indoor model that has been applied in advising emergency responders on protecting buildings against accidental or intentional chemical or biological releases. Dr. Chan earned her Ph.D. in Civil and Environmental Engineering from University of California, Berkeley in 2006.
