碩士 === 國立交通大學 === 機械工程系所 === 96 === 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.
