近年來建築節能技術受到重視，建築能耗中又以空調用電佔最大的比例，為瞭解我國辦公建築的分離式空調能耗情形並進行比較，本研究以台南沙崙綠能科技示範場域的旋轉建築測試平台SPINLab進行實驗，SPINLab外部有溫濕度感測器、風速、風向、雨量計等設備，用以收集室外氣候條件資料，內部有收集數據的監控室及兩間測試室，測試室內有溫濕度感測器、照明設備、遮陽設備、分離式空調、熱負載及玻璃帷幕牆等，且玻璃帷幕牆面向的方向即為建築面向方位。
本研究透過實驗探討各項實驗條件對建築室內環境及空調耗電量的影響，實驗項目包含空調設定不同溫度、室內有無風扇、採用台電的空調間歇降載制度及室內有無遮陽設備等，且於夏季及秋季分別進行相同實驗，後續比較兩者得出結論。實驗過程中遇到A室與B室的量測數值有落差的問題，後續選擇以同測試室的數據進行比較及分析，並透過計算變異係數選取外部條件相近的數據。
研究結果表明建築方位、遮陽設備、風扇、空調調控方式等，均對室內溫度、室內濕度及空調耗電量有不同程度的影響，其中室內受日照的時間為重要的影響因素，在建築方位的比較中，窗口面向南方的實驗因室內全天沒有受到太陽直射，溫度與濕度起伏小，空調耗電量低，且差異主要體現於下午時段，而遮陽設備、風扇、調控空調設定溫度亦對室內環境造成影響，並對用電量提供效益，另外，夏季與秋季的季節溫度差異也是影響空調能耗的關鍵，在間歇降載的實驗中，不同季節下的室內溫度回升幅度對空調降載的效益有關鍵的影響。

In recent years, energy-saving technologies have been receiving increasing attention, where air-conditioning electricity accounts for the largest proportion of building energy consumption. In order to understand and compare the energy consumption of split air conditioners in office buildings, in this study, the Subtropical Performance Testbed for Innovative Energy Research in Buildings, SPINLab, is used in order to conduct experiments in Tainan Shalun, Taiwan. The outside of SPINLab is equipped with temperature and humidity sensors, an anemometer, a rain gauge, a pyranometer, and other equipment that can be used to collect data on outdoor climate conditions. There is a monitoring room for collecting data and two testing rooms inside the building. There are temperature and humidity sensors, lighting equipment, shading equipment, a split air conditioner, heat loads, and glass curtain walls in the test room, where the direction of the glass curtain wall conforms to the orientation of the building.
This study explores the effects of various experimental conditions on the building’s indoor environment and the power consumption of air conditioners. The experimental items include different air conditioner settings, the effects of a fan, use of the intermittent control method for the air conditioner, and the influences of shading equipment, etc. The same experiment is carried out in summer and autumn, and conclusions are drawn based on subsequent comparison of the seasonal data. During the experiment, we encountered the problem of a gap between the measured values of room A and room B. The subsequent choice was to compare and analyze the data from the same test room and to select data with similar external conditions by calculating the coefficient of variation.
The research results showed that the building orientation, shading equipment, fans, air conditioning control methods, etc., all have varying degrees of impact on indoor temperature, humidity, and power consumption related to the use of an air conditioner. Among them, the time of indoor sunlight is an important factor. In the comparison of the building orientation, the experiment with the window facing south was not exposed to direct sunlight throughout the day, so the temperature and humidity fluctuated slightly, and the air conditioner power consumption was low. The difference was mainly reflected in the afternoon, while the shading equipment, fans, and temperature control on the air conditioner also affected the indoor environment and provided benefits in terms of electricity consumption. In addition, the difference in the seasonal temperature between summer and autumn was also a key to the air conditioner energy consumption. In the intermittent control experiment, the increase in the indoor temperature in the different seasons had a key influence on the benefits associated with the use of an air conditioner.
