摘要

本論文以北部某辦公大樓節能改善案例為標的，以eQUEST建立大樓整體耗能模型。本研究先由現場進行資料蒐集，將資料逐步輸入eQUEST分析軟體內，完成建物模型後，以不同的空調設備模型及不同之控制手法，模擬分析改善前及改善後耗能，並對參數作互相比較。EEWH-RN評分節能選項佔比甚高，故本研究對空調系統提出節能改善手法。分別針對空調主機系統、水側及空氣側三大部分提出節能手段，本研究案例主機系統冰水主機並未更換，只將原先儲冰鹵水水路及水泵一併移除，新設置的一次側冰水水路則加入變頻控制，另外在空氣側部分則新設末端變風量箱(VAV BOX)，並利用TAB工程使室內風量分佈更加均勻。
本研究結果用於EEWH綠建築評估中的EEWH-RN舊建築改善類，進行節能分析並利用減碳效益評估法推算出最大減碳潛力(CEc)及減碳效益百分比(ΔCRr)。結果顯示，改善後空調耗能節省了646,200kWh/yr，占建築物總耗能8.37%，占空調耗能則為18.34%；由EEWH-RN評估得知最大減碳潛力(CEc)為3084167.9 (kg-CO2/yr)；減碳效益百分比(ΔCRr)為13 %，等級為銅級綠建築。本研究案例只針對空調耗能做節能改善，即可獲銅級綠建築，顯示空調節能之重要性。

A building in northern that just underwent energy saving retrofitting was taken to be the case study. A building energy model was setup for the building using eQUEST program. Building information including the most energy use equipment was collected as data input for annual energy analysis. The performance models of the air- conditioning system before and after the retrofitting were used in the analysis. The different control methods were used to simulate the improved energy consumption after the retrofitting. Parameters of importance were compared before and after the retrofitting. In the EEWH-RN ratings energy saving constitute a fairly high proportion. Means to save energy for air-conditioning was studied for the chiller, the water-side and the air-side system. In the case study water chiller was not replaced but the ice storage system, and therefore renovated piping and variable water pumps were analyzed. TAB was applied to optimize the air-side system including the VAV boxes.
EEWH-RN was used to assess energy saving in existing buildings in terms of carbon emission reduction potential (CEc) and the carbon reduction ratio (ΔCRr). The results show that the air-conditioning energy saving is 646,200kWh, accounting for 8.37% total energy consumption for the buildings, and is 18.34% for the air- conditioning system. EEWH-RN assessment results obtained for carbon emission reduction potential (CEc) is 308,4167.9 (kg-CO2 / yr), and the carbon reduction ratio (ΔCRr) is 13%. The results correspond to the copper grade green building. In the case study only the air-conditioning system was retrofitted and copper grade green building was achieved. The results show the importance of air-conditioning energy saving.
