Why ventilation matters?
Date: April 16, 2021 (Friday), 3:30pm – 4:30pm
Speaker: Professor Yuguo Li, Chair Professor of Building Environment
Moderator: Professor Dennis Leung, Head of Department of Mechanical Engineering
Mode: ZOOM
Although airborne transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has already been acknowledged by leading health authorities, no existing standard for building ventilation yet considers the need to control respiratory infection. The speaker shall explain why outdoor has a lower infection risk than indoor, and why poor ventilation can worsen both short- and long-range inhalation. The speaker shall present a new equal CO2 exposure method to derive a set of minimum ventilation rates and associated maximum CO2 concentrations in indoor settings with various activity levels (rest, light-, moderate- and heavy-exercise) and breathing modes (breathing, speaking, singing and loudly speaking). Opportunities for innovation will be mentioned.

Yuguo Li is a Chair Professor of Building Environment. His current research topics include city climate, environment studies of infection and indoor environment. Since early 2020, he has collaborated with WHO, Guangdong CDC, Hunan CDC and Jiangsu CDC and studied the transmission routes of SARS-CoV-2 in buildings. He is a member of the WHO IPC GDG and WHO Environment and Engineering Control Expert Advisory Panel (ECAP) for COVID-19. He also serves as Editor-in-Chief of Indoor Air.
InnoEdge creates opportunities for active exchange and learning for the advanced technologies and/or research outcomes from pioneering Engineering projects in the Faculty of Engineering. It is an innovative and multidisciplinary programme for bringing together like-minded students in an active peer learning community where they can delve into diverse topics pertinent to the use of cutting-edge technologies.
