摘要

在現今住宅或學校等多為自然通風建築，只有部份時間或空間會利用空調系統；以經濟狀況來考量，全時及所有空間均利用空調系統，對許多家庭及部份學校而言是相當大的負擔。對使用空調系統之建築，建築外殼隔熱設計能改善室內熱環境之舒適性，進而達到節約能源及節省電費之目的。
本研究以改變建築物屋頂型式之方式，進行空調耗電量之模擬，比較全年及夏季各屋頂型式在空調用電量上的差異，並籍此分析建材與屋頂型式對空調用電量之影響。
本研究之結果發現：
1．改變屋頂型式確實對建築物頂樓之空調用電量有明顯之影響，且其影響較使用相同屋頂型式但熱阻係數不同之建材明顯。
2．各類傾斜式屋頂傾斜之面向與角度對空調用電量亦有一定之影響。
3．欲設計雙層通風之屋頂型式，建議配合長期之氣象觀測以決定頂樓鋼架通風口的設計型式。

Under the circumstance that the dwelling house or school is mostly in the type of natural ventilated building now, only part time or space will use air-condition system. Considering the economic situation, the families and schools may have sizable burdens with the air-condition system in the full-time operation and constructed in all space. The appropriate design of the thermal insulation for building envelope can improve the comfortable of the indoor thermal environment and achieve the purpose of saving the energy and money.
The different types of rooftop were used to simulate the energy consumption in the summer and the whole year. The analysis supplied the effects of the rooftop forms to the energy consumption of air conditioner. The conclusions of this research found:
1. The types of rooftop significantly affect the energy consumption more than the types of materials.
2. The directions and angles of rooftop will affect the energy consumption.
3. The design of inlet in the rooftop of double-layer ventilation should accommodate with long-time metrological data.
