以能源分析模擬軟體(eQUEST)評估EEWH與LEED之認證

Abstract

本論文利用動態能源模擬軟體(eQUEST)來分析建築物的整體耗能趨勢以及評估EEWH與LEED的認證。模擬的目標為台北萬華運動中心，其為地下兩層及地上七層的建築物。萬華運動中心總共採用了六個節能手法(ECMs)。為了瞭解各個節能手法的經濟效益以及耗能趨勢，本論文分析了各個節能手法的特性、初置成本以及回收年限。研究結果顯示照明密度降低(LPD)每年可節省52,828元，且其無須設備初置成本，為優先考慮的節能手法。可變水量系統(VWV)每年可省129,277元，回收年限為2.1年，為所有節能手法中最短，經濟效益最高的方法。反之，外氣冷房系統每年可節省51,878元，但其回收年限為7.56年，是所有節能手法中最長的，也是最後考慮採用的節能手法。為了評估EEWH系統的不足之處，本論文首先討論EEWH與LEED相同以及獨特的指標，然後專注於分析空調系統節能效率(EAC)的各個參數(空調節能技術效率標準)以及相對的空調節能技術，尋找改進EEWH評估系統的方法與策略。最後，本論文提出了許多改進的方法，提供設計者ㄧ個整體的能源分析觀念，並讓台灣未來綠建築能源分析的改進有一個參考的依據。

Through the use of dynamic energy simulation tool (eQUEST), this study analyzes the building integral energy consumption and evaluates EEWH and LEED performance. The simulation objective in this study is the Taipei Wan-Hua Sports Center, which includes two basements and seven floors. There are six energy conservation measures (ECMs) in this building. In order to understand the economy benefit and the energy consumption trend of these ECMs, this study analyzes the characteristic of ECM, initial cost and payback. The results show that Lighting Power Density (LPD) reduction can save 52,828 dollars per year. It is the first choice for the owner because it needs no initial cost. Variable water volume (VWV) system can save 129,277 dollars per year. Its payback is equal to 2.1, which is shortest within these ECMs, and it also has the best economy benefit. On the contrary, OA air conditioner system can save 51,878 dollars per year. However, its payback is equal to 7.56, which is longest within these ECMs. This ECM is also the last method, which designer considers adopting. In order to examine the defects and find improvement methods and strategies in EEWH system, this study compares the similar and unique indicators of EEWH and LEED assessment systems, and then it focuses on the analysis of EAC formula parameters (energy-saving efficiency) and corresponding ECM. Eventually, several improvements for EEWH are suggested. It provides an integral energy analysis concept for designer and an improvement reference for Taiwan building energy analysis in the future.
