Henry Willem is a Project Scientist with the Energy Performance of Buildings group. His current research focuses on the evaluation of indoor air quality mitigation strategies in U.S. homes and their impacts on residents’ exposure. The evaluation was carried out through field intervention studies to assess the impact of ventilation rates on indoor air contaminants exposures and to understand the benefits of using low-emitting materials as source control. The research outputs will be used to support the development of future health-based ventilation standards.

Henry Willem received a dual PhD degree in Indoor Air Sciences under the joint program between the National University of Singapore and the Technical University of Denmark in early 2007. He was awarded the Ralph-Nevins Award on Human Physiology by ASHRAE in 2008. In the same year, he received the Yaglou Award from ISIAQ. The awards are given for his work in the area of perception, health responses, and work performance, and the application of biomarkers to understand the underlying mechanisms of human responses to the indoor environment. Dr. Willem has worked as co-investigator on five research projects in the areas of thermal comfort and indoor air quality responses, personalized ventilation system, ozone-initiated indoor chemistry, and airborne droplets dispersion. He has published his research in Building and Environment, ASHRAE Transactions, and Epidemiology; and co-authored a review article for the Elsevier Encyclopedia of Environmental Health.
