本站小编 Free考研考试/2022-01-30

Dr. Wei WU


Education
PhD, Tsinghua University



Staff title
Assistant Professor





Dr. Wei Wu received his Bachelor’s degree from the Department of Building Environment and Energy Engineering at Huazhong University of Science and Technology in 2010. He obtained his PhD degree from the Department of Building Science at Tsinghua University in 2016. He was formerly a visiting scholar of the Center for Environmental Energy Engineering at University of Maryland in 2013. Since 2016, he served as a guest researcher of the Energy and Environment Division at the National Institute of Standards and Technology. He joined the City University of Hong Kong as an assistant professor in the School of Energy and Environment in July 2018.
Dr. Wu’s research is focused on sustainable building energy technologies. Aiming to mitigate the energy use and environmental impact in building sector from widened and deepened perspectives, his research work has been conducted at multi-levels: (1) investigating merits and potentials of alternative working fluids for heat pumps; (2) proposing a cluster of technologies for performance improvement of heat pumps; (3) exploring design and optimization methods of HVAC systems in net-zero energy buildings.
