摘　　要：外窗作为建筑围护结构的薄弱环节,其造成的热损失约占建筑总热损失的一半以上,合理的外窗设计对建筑节能具有极其重要的意义。外窗一方面带来太阳的光和热,同时较小的热阻也增加了室内外的温差传热,外窗的光热作用对建筑照明、采暖和空调能耗产生耦合交叉的影响。然而,目前关于外窗的研究却很少从全局能耗的角度分析外窗设计参数对建筑的综合节能作用。基于此,以成都某酒店建筑为案例,采用建筑能耗模拟和实验验证相结合的方法开展外窗全局节能优化研究。结果表明,窗墙比对全局能耗的影响最大,节能潜力在20%以上,其次是外窗朝向,当朝向为南时,全局能耗最低,最大可节能7.1kWh/m^(2)。而日射得热系数和传热系数的优化潜力相对较低,传热系数每降低0.1W/(m^(2)·K),全局能耗降低0.19kWh/m^(2);日射得热系数每增加0.1,全局能耗增加0.94kWh/m^(2)。研究可为酒店外窗的节能优化设计和改造提供技术支撑和方法指导。Since exterior windows account for more than half of the total heat loss in buildings,a well-designed exterior window plays a crucial role in energy-saving for buildings.On one hand,exterior windows allow sunlight and heat to enter the building,while their lower thermal resistance also increases the heat loss between the interior and exterior.The thermal and lighting effects of exterior windows have a coupled impact on the energy consumption of building lighting,heating,and air conditioning.However,there is a lack of research that comprehensively analyzes the impact of exterior window design parameters on building energy consumption from the perspective of global energy consumption.In this study,a hotel building in Chengdu is taken as an example to conduct research on the Global energy-saving optimization of exterior windows,using a combination of building energy consumption simulation and experimental verification.Results show that the window-wall ratio has the greatest impact on the global energy consumption,and the energy saving potential is more than 20%,followed by the external window orientation.When the orientation is south,the global energy consumption is the lowest,and the maximum energy saving is 7.1kWh/m^(2).However,the optimization potential of solar heat gain coefficient and heat transfer coefficient is relatively low.When heat transfer coefficient decreases by 0.1W/(m^(2)·K),the global energy consumption decreases by 0.19kWh/m^(2).The global energy consumption increases by 0.94kWh/m^(2) when the solar heat gain coefficient increases by 0.1.
