Gold Medal

Dr. Edwin Tso
Assistant Professor, School of Energy and Environment (SEE), and Stanley Liu Sai, PhD student, SEE

“Intelligent Thermo-responsive Window for Indoor Thermal Management and Energy Saving in Buildings”

The novel smart window can autonomously regulate solar transmittance in response to the outside temperature. The smart window is transparent in cold weather, allowing solar radiation to pass through to warm a room, and is opaque in hot weather, blocking solar radiation to prevent overheating. This invention can promote the development of energy-efficient and sustainable buildings.
