窗墙转换构件对室内热环境及建筑能耗的影响
Impacts of Window-Wall Transition Components on Indoor Thermal Environment and Building Energy Consumption
摘要
Abstract
Combined with the requirements for building envelope structures in hot-summer and cold-winter regions,a dynamically variable window-wall transition component(WWTC)is proposed.The WWTC is equipped with a mechanically adjustable high-performance thermal insulation structure on the indoor side of the exterior window,which allows the window-to-wall ratio to be dynamically adjusted accord-ing to outdoor conditions,seasonal variations and day-night operating modes.Taking an ultra-low energy residential building in Shanghai as the research object,simulation methods are adopted to analyze the impacts of the WWTC on indoor thermal comfort and building energy consumption.The WWTC achieves the best temperature regulation for west-facing rooms,followed by east-facing ones,with mild improvements for south-facing and north-facing rooms.It effectively pro-longs thermal comfort hours for rooms of all orienta-tions in both cooling and heating seasons.It contrib-utes the most to prolonging thermal comfort hours for west-facing rooms,followed by east-facing and south-facing rooms,with the minimum contribution observed in north-facing rooms.The WWTC installa-tion saves energy for rooms of all orientations:west-facing rooms yield the greatest energy savings,fol-lowed by east-facing and south-facing rooms,while north-facing rooms see the weakest performance.Across cooling and heating seasons,WWTC improves indoor thermal comfort and cuts building energy use for rooms of all orientations.For residential buildings in Shanghai,priority should be given to installing the WWTC in west-facing rooms.关键词
