Constructing a Dual-Index Regulation for the Design of Envelope Performance of Hybrid Ventilated School Building

Responding to the hot humid climate, the Taiwan government expects to broadly install air-conditioning in classrooms to provide a comfort study environment for school buildings and prevent the risk of overheating; therefore, corresponding to the installation of air-conditioning, it is important to draw up the energy-saving strategy while considering the thermal comfort. This study firstly discussed the insufficiency of the regulations in Taiwan, and then suggested a dual-index which take building envelope performance and thermal comfort into consideration simultaneously through regression analysis. Based on the simulation results, a school building envelope design criteria for mixed-mode thermal management which simultaneously considered the cooling load and natural ventilation potential is proposed in this study. it is expected to analyze and provide accurate information for energy-saving potential and thermal comfort efficacy at the initial design stage through this criteria.
