可变建筑表皮的环境调节因素对建筑能耗的影响分析

Influence of Environmental Factors on Building Energy Consumption of Dynamic Fa?ade

“双碳”目标是我国实现经济绿色低碳升级的重要环节,而建筑作为耗能主要部分,面临着巨大挑战。从太阳辐射、通风量、表皮蓄热性能和热阻4个因素出发,分析可变建筑表皮的环境调节因素对建筑能耗的影响。针对厦门地区某南向办公室,设计多种可变建筑表皮形式并设置了4组分析模型,利用EnergyPlus软件对建筑能耗进行模拟分析,对比在各种调节因素的影响下建筑能耗及节能率变化,寻求最佳节能状况下的建筑外表皮调节方式,为之后的建筑设计提供参照。研究结果表明,基于4种环境调节因素的可变建筑表皮措施均能减少建筑能耗,节能率在2.19%~66.79%之间,其中调节通风量的可变建筑表皮节能率最高。

The “Dual-Carbon Goals”(realizing carbon peak before 2030 and carbon neutrality before 2060) is an important part of China's green and low-carbon economic upgrade,and buildings,as a major part of energy consumption,are facing a huge challenge.The paper is based on the four factors consisting of solar radiation,ventilation,thermal storage and thermal resistance.A numerical simulation to a south-facing general office in Xiamen is carried,by setting a variety of varied skin forms,through the energy simulation software EnergyPlus,the building energy consumption and energy saving rate are compared.Seeking the best way to regulate the building skin under energy-saving conditions to provide some reference for the subsequent building design.The results show that these facades can reduce building energy consumption,and the rate of energy saving is between 2.19%~66.79%,of which the highest is variable shading regulated ventilation.
