Viruses can spread readily in buildings, especially in office or other commercial/institutional buildings that have high occupant density, many shared spaces and surfaces, and significant recirculation of indoor air. Owners and operators of commercial and institutional buildings responded quickly and decisively to the COVID-19 pandemic with a number of effective strategies, including moving non-essential workers to remote sites to reduce occupant density, requiring personal protective equipment (PPE), introducing continuous disinfection strategies for common surfaces, and increasing outdoor air ventilation rates and air filter efficiencies. These strategies were informed by previous virus transmission events that have occurred in buildings (e.g., SARS) and by panels of experts who worked together to develop and quickly publish effective guidelines for buildings. However, these strategies are not all sustainable beyond the current pandemic crisis. This webinar will address a variety of issues relevant to virus transmission and mitigation in buildings, including developing an understanding of: 1) mechanisms for virus transmission in buildings informed by previous and evolving studies, 2) short-term mitigation strategies that have been developed to address the COVID-19 pandemic, 3) impacts of mitigation strategies on energy use and operation of buildings, and 4) future "virus-proof" designs and strategies for buildings.

He is also a recipient of the Penn State Engineering Alumni Society’s World-Class Engineering Faculty Award.
Dr. Brandon E. Boor is an Assistant Professor of Civil Engineering (Architectural Engineering Area) and Environmental and Ecological Engineering (by courtesy) at Purdue University. Dr. Boor conducts research on the physics and chemistry of indoor air. His group applies state-of-the-art measurement techniques to explore the dynamics of indoor air pollutants in diverse indoor environments. Dr. Boor teaches courses on indoor air quality, thermodynamics, and architectural engineering and advises an undergraduate air quality engineering service learning team. He received his Ph.D. in Civil Engineering from The University of Texas at Austin in 2015 and is a recipient of a 2019 National Science Foundation CAREER Award.
Dr. Qingyan “Yan” Chen is the James G. Dwyer Professor of Mechanical Engineering at Purdue University, USA. He serves also as the Editor-in-Chief of the international journal “Building and Environment”. Dr. Chen was the founding co-Principal Director of the Federal Aviation Administration (FAA) Center of Excellence for Airliner Cabin Environment Research from 2004 to 2010. Dr. Chen earned his B.Eng. in 1983 from Tsinghua University in China and M. Eng. in 1985 and Ph.D. in 1988 from the Delft University of Technology in the Netherlands. He conducted his post-doctoral research as a Research Scientist at the Swiss Federal Institute of Technology (ETH-Zurich) and worked as a Project Manager for TNO in the Netherlands. Dr. Chen has received the Distinguished Achievement Award for “individuals who have made substantial contributions to the field of building performance simulation over the course of their careers” from International Building Performance Simulation Association (IBPSA) in 2013, the John Rydberg Gold Medal for “outstanding contribution to the advancement of modelling and measurement of ventilation and air distribution in buildings" from the Scandinavian Federation of Heating, Ventilating and Sanitary Engineering Associations in 2011, and the Willis J. Whitfield Award "for significant contributions to the field of contamination control through numerous published papers, studies, and reports" from the Institute of Environmental Sciences and Technology in 2007. Dr. Chen's current research topics include indoor environments; aircraft cabin environments; and energy-efficient, healthy, and sustainable building design and analysis.
