摘要(中)	建築相關產業使用消耗全球40％的能源，並且普遍大眾對於建築物的要求變得嚴謹，在熱舒適性、視覺舒適性和室內空氣品質等的要求日漸提高，導致能源消耗的增加，故勢必針對建築舒適性與節能進行深入探討。而本研究與科技部進行計畫合作，於中央大學內建置了低耗能智慧建築，本論文亦將針對此建築實施探討空間舒適性與能源消耗分析。首先藉由當地氣候條件之資料，配合使用ANSYS Fluent流場模擬分析，將流場空間分割成室外與室內空間，並了解不同季節之室外流場之常態分布，最後發現該目標建築物周圍於一年四季之常態風向皆為北風，並依此作為室內自然通風邊界設定之參考，在經由驗證室內流場模型後，發現其相對誤差小於3%，表示研究結果成功將室內外流場之關係連結在一起。接著在室內流場模擬分析後，發現其於春、秋以及冬天時，大部分可依靠開窗的策略使室內保持常態的舒適感受，並且兼顧空氣品質之標準。而在空調模式分析裡，模擬結果顯示，於不同建築物中，其能夠根據空間形狀以及氣流出口位置進行空調位置設計，以使整體空間更加舒適。最後於能耗模擬中發現照明技術的開發可節省大量能源，並且整體建築能耗比能源局公告之用電參考指標低了約17.2%。
摘要(英)	The increase in demand for energy has given huge importance to energy saving and utilization worldwide. Construction-related industries consume 40% of the world′s energy, and the general public is more concerned about comfortable living such as thermal comfort, visual comfort and indoor quality, which leads to the increase in energy consumption. Therefore, an in-depth research on building comfort and energy saving is vital. This research aims to design a low energy building with thermal comfort and indoor air quality at National Central University. Also, the space comfort and energy consumption analysis of this building will be investigated. First, the local climatic conditions in the locality of the building in various seasons is collected and then the ANSYS Fluent flow field simulation analysis is performed for the indoor and outdoor flow field spaces to understand the normal distribution of outdoor flow fields in different seasons. The outdoor flow field simulation results show that the normal wind direction around the target building is northerly in all seasons, and this is used as a reference for the indoor natural ventilation boundary setting. After verifying the indoor flow field model, it was found that the relative error was less than 3%, indicating that the flow field simulations results are accurate and a relationship between the indoor and outdoor flow fields is explored. Further, the simulation and analysis of the indoor flow field in spring, fall and winter seasons shows that the normal indoor thermal comfort and air quality standards in the building can be maintained by opening the windows of the building. But have to rely on air conditioners in the summer for indoor thermal comfort. So for the indoor comfort analysis in the air conditioning mode, the flow field simulation results show that the position of air conditioning has to be decided according to the indoor space, shape and the air outlet of the building to make the overall space more comfortable. Finally, it is found in the energy consumption simulation that the development of energy efficient lighting technology can save a lot of energy, and the energy consumption of the target building is about 17.2% lower than the electricity reference index announced by the Energy Bureau. This strategical approach followed in this research concludes that natural ventilation can be used for indoor comforts in different seasons depending upon the local climatic conditions. This research could be a reference for construction industry that position of indoor thermal comfort equipment plays a key role for efficient maintenance of thermal comfort inside building. This research is helpful in designing an energy efficient and low energy building.
