摘要

建築節能減碳是臺灣永續發展之重要研究方向，本研究主要探討建築外殼節能措施於臺灣氣候下之空調節能效益，利用兩棟實驗屋，一棟為對照組，另一棟則採用不同之外殼節能措施（外殼U值、內外遮陽及開窗率），搭配室內外氣候監測系統（室內外溫濕度、風速、太陽輻射量），並於兩棟實驗屋加裝變頻式冷氣及數位電表監測其空調用電歷時，以了解不同節能措施曝露於本土氣候條件下之實際空調節能效益；同時，利用建築耗能分析軟體eQUEST建立實驗屋之數值模型，並比對數值模擬的空調耗電量與實驗屋實際空調運轉數據，以利瞭解建築耗能分析軟體準確性。

Reducing energy use for space cooling in buildings is a key measure to energy conservation and environmental protection in places having hot and humid weather, such as Taiwan. In this research, we use two identical experimental houses with the climate monitoring system to estimate the energy consumption of air-conditioning system with different building envelope strategies (the U-value of the overall wall and roof, the external and internal shading device, the window opening area ratio, etc.). We also adopted the energy simulation free software eQUEST, which is based on the well-known DOE-2 program, to estimate the energy saving of different strategies. Actual building and operating data were fed to eQUEST to calculate the instantaneous electric consumption due to air conditioning and the comparison between measured and predicted electric consumption is presented to understand the accuracy of the energy simulation program.
