摘要(中)

隨著台灣對於能源需求的增加，減少碳排放和提高建築物的能源使用效率成為迫切需要解決的問題。台灣建築物大多使用空調系統來提供冷卻和改善室內熱舒適度，但冷氣設備會消耗大量電力能源。本研究結合自然通風模式與建築物能源模式來預測不同情境下平房住宅建築物的室內溫度，旨在探討混合式通風對建築節能效益的影響。模擬結果顯示，採用自然通風能有效降低室內溫度、不舒適時數以及冷房度時，從而達到節能效果，而其中採用貫流通風因為有較高的通風率，其降溫效果又優於單側雙開口與單一開口之自然通風。此外，藉由自然通風與建築物能源模式探討台北、台中和高雄的住宅建築物自然通風量的節能效率分別為10.5%、17.9% 和 24.3%。最後，本研究還探討了1980至2020年間台灣全球暖化趨勢對住宅建築物冷氣用電量的增加趨勢。研究結果顯示：隨著全球暖化導致的氣溫升高，建築物冷氣用電量呈現穩步上升趨勢，冷氣用電需求每十年增加率約 35.3%。因此在未來建築設計中應更注重混合通風策略，以減少對機械冷卻系統的依賴，達到節能減碳的目標。

摘要(英)

With increasing energy demand in Taiwan, improving the energy efficiency of buildings and reducing carbon emissions have become pressing issues. Most buildings in Taiwan use
air-conditioning systems to provide thermally comfortable indoor environments, whereas these systems consume significant amounts of electricity. This study combines a natural ventilation model with a building energy model to the predict indoor temperatures of a single-story residential building under different scenarios, aiming to explore the impact of hybrid ventilation on building energy efficiency. Simulation results show that natural ventilation can effectively reduce indoor temperature, discomfort hours, and cooling degree hours, thus saving energy. Among the natural ventilation strategies, cross-ventilation, due to its higher ventilation rate, has a better cooling effect compared to two-opening on the same wall and single-opening ventilation. Additionally, the energy-saving efficiencies of hybrid ventilation for the same residential building in Taipei, Taichung, and Kaohsiung are 10.5%, 17.9% and 24.3%, respectively. This study also explores the effect of global warming trend between year 1980 to 2020 on the cooling energy demand of residential buildings in Taiwan. The simulation results indicate that the increase rate of cooling energy demand is about 35.3% per year. Therefore, buildings should adapt hybrid ventilation to reduce the electricity consumption of mechanical ventilation and achieve the goals of energy saving and carbon reduction.
