自然通風對住宅式建築物降溫效果之研究

Natural ventilation of buildings can remove the excessive heat and indoorcontaminants, while reducing the energy consumption of air conditioner andmechanical ventilation. However, the Building Energy Saving Regulation ofTaiwan merely requires an estimation of the potential of natural ventilation andenergy consumption of building envelope; neglect the effects of outdoortemperature, indoor heat sources, and natural ventilation rate on the indoortemperature. This project plans to develop a building energy simulation model toexamine the influence of natural ventilation on the indoor temperature andthermal comfort of typical Taiwanese residential buildings under various climateconditions. The simulated indoor temperature will be compared with observedtemperature inside the Energy-Saving Building of NCU. The validated buildingenergy model could be used to simulate the indoor temperature under differentsolar radiation, outdoor temperature and natural ventilation rate. The findings ofthis project will be valuable to architects in evaluating the cooling effect of naturalventilation for residential buildings in Taiwan.
