摘要
微气候与建筑能耗关系密切,通过改善微气候环境降低建筑能耗已经成为建筑节能设计领域的一个重要方向。以沈阳市尚盈丽景小区为例,依托微气候模拟软件ENVI-met和建筑能耗模拟软件EnergyPlus建立了微气候影响下的建筑能耗耦合模型,对夏季典型气象日的建筑逐层制冷能耗进行精准分析。实验结果表明:随着建筑高度的增加,局地微气候与城市气候对建筑制冷能耗影响的差异逐渐减小,微气候主要通过影响空气渗透得热量来影响建筑制冷能耗。微气候影响下全天建筑总制冷能耗相对于城市气候下建筑制冷能耗增加了9.63 kW·h,增长了4.28%。针对局地微气候差异对建筑制冷能耗的影响规律,提出优化住区规划布局、分区域提升围护结构热工性能、优化立面开窗等策略,从而实现居住区节能设计。
Microclimate is closely related to building energy consumption.Reducing building energy consumption by improving the microclimate environment has become an important direction in the field of building energy-saving design.Taking Shangying Lijing Community in Shenyang as an example,relying on the microclimate software ENVI-met and the building energy consumption simulation software EnergyPlus,a coupling model of building energy consumption under the influence of microclimate is established,and the cooling energy consumption of buildings on typical weather days in summer is accurately analyzed.The experimental results show that with the increase of building height,the difference between the influence of local microclimate and urban climate on building cooling energy consumption gradually decreases,and the microclimate mainly affects the building cooling energy consumption by affecting the heat gain of air penetration.Under the influence of microclimate,the total cooling energy consumption of buildings increased by 9.63 kW·h compared with that under urban climate,an increase of 4.28%.In view of the influence of local microclimate differences on the cooling energy consumption of buildings,strategies such as rational planning and layout,improving the thermal performance of the envelope structure in different regions and optimizing the facade window opening are proposed,so as to realize the energy-saving design of residential areas.
