摘　　要：近零能耗建筑的研究是我国建筑节能低碳发展的必然趋势,而外百叶遮阳是提高近零能耗建筑能效的有效措施之一,外百叶遮阳应用于近零能耗建筑的节能采光耦合作用值得深入研究和讨论。因此,该研究通过EnergyPlus能耗模拟与Daysim采光模拟,分析并量化了我国不同气候区百叶倾角下近零能耗建筑外百叶遮阳的节能采光耦合特性,并在此基础上,给出了不同气候区近零能耗建筑外百叶遮阳综合节能(电)潜力最大的百叶倾角推荐表,填补现有建筑节能标准的空白,并为外百叶遮阳在我国不同气候区近零能耗建筑中的应用提供设计参考。With technological progress and social development,study on near-zero energy buildings(NZEBs)has become an inevitable trend to achieve building energy efficiency and emission reduction.The external venetian blind shading(EVBS)is one of the effective technologies for NZEBs to improve overall performance,and the coupling impacts of EVBS on energy saving and daylighting should be further analyzed and discussed.Based on energy simulation by EnergyPlus and daylighting simulation by Daysim,the coupling characteristics of energy saving and daylighting of EVBS with diverse shading slat angles for NZEBs in different climate zones of China were analyzed and quantified.And the recommendation table of shading slat angle with maximum comprehensive energy(electricity)saving potential for EVBS in NZEB was proposed.The research conclusions can fllthe gap in building code and provide design reference for the application of EVBS in NZEBs in different climate zones of China.
