SPET: A Scalable Personalized ThermalComfort Platform for Building Energy Conservation

The heating, ventilation and air-conditioning (HVAC) system accounts for more than half of building energy consumption in a building. The scalable personalized thermal-comfort (SPET) platform developed by PolyU can quantitatively estimate the thermal comfort of any individual occupants, and support proactive temperature setting mechanisms, instead of setting a conservative temperature. It can reduce energy waste by setting lower temperature than required. It optimizes both thermal comfort and energy conservation. This platform was shown to save energy by 18% and improve thermal comfort by 33.8%.
