| dc.description.abstract | The aim of this study is to reduce building energy consumption by minimizing the cooling energy demand in existing buildings as case studies. Double skin façade (DSF) strategy has been introduced as an alternative of building façade technology in providing thermal comfort and reducing heating and cooling load in a building. The research questions addressed to find the possibility of applying naturally ventilated DSF strategy in hot humid climate, such as Taiwan and to see how is the impact of changing the parameters of the façade. Two case studies were presented, with typical function and building shape form. Both cases are modified in air gap width and outer skin material. The calculation of building energy performance was conducted in full scale simulation using DesignBuilder-EnergyPlus as simulation software. The study run firstly by simulating the base case which is the existing conventional single skin façade. As first scenario, heat gain calculation was conducted to determine which side of the façade are belong to the high heat gain sides that the DSF will be applied. The second scenario was obtained by installing DSF on all sides instead only on particular side. The results show that in case study 1, for scenario 1 and 2, the application of DSF could reduce the cooling energy demand up to 31.28% and 34.69% respectively by combining 1.2m air gap and double glazed Low E (Low Emissivity). While in case study 2, the best alternative in reducing cooling energy was also obtained by combining 1.2m air gap with double glazed Low E. The results were 11.94% and 21.26% in scenario 1 and 2 respectively. The difference in cooling energy reduction between scenarios is up to 8.5MWh in case study 1 and 15.33MWh in case study 2. Simulation results also show that the DSF could still perform well in the summer season. Thus, it can be concluded that the DSF strategy is applicable in hot humid climate such as Taiwan. | zh_TW |
| dc.description.abstract | 雙層帷幕外牆是目前建築物外牆設計方法之一，此方法可直接提供舒適之室內溫度，以改善冷暖氣之能源消耗。本研究主要目的在於探討在潮溼與悶熱的台灣環境裡，運用自然通風與雙層帷幕外牆之設計，降低既有建築物室內冷卻之能源消耗。本研究運用DesignBuilderEnergyPlus作為模擬工具，分別針對兩棟台灣國立中央大學之既有校舍進行雙層外牆間之空隙與外牆材料變異之模擬，並研究參數改變後之能源差異。第一個模擬情境，僅就單層外牆與雙層外牆之最高受熱面進行數據蒐集與差異探討；第二個模擬情境，假設建築物所有外牆皆採用雙層外牆之設計之差異。在兩個情境模擬下，案例一顯示當採用1.2公尺之空隙設計與Low-E玻璃時，分別可節省31.28% 與34.69%之建築物室內冷卻能耗；案例二之結果亦顯示採用1.2公尺之空隙設計與Low-E (Low Emissivity) 玻璃，是能源效率最高之組合，分別可節省了11.94% 與21.26%之冷卻能耗。而在不同的模擬情境或參數改變下，案例一與案例二分別至少改善8.5MWh及15.33MWh之能耗。此模擬之結果顯示，即使在潮溼與炎熱的台灣夏季，雙層帷幕外牆設計仍具備一定之效能，亦可作為未來台灣建築物節約能源策略之一。 | en_US |
