新规范实施后广西居住建筑围护结构节能构造研究

Research on energy-saving structure of enclosure structure of residential buildings in Guangxi after implementation of new code

为研究GB 55015—2021《建筑节能与可再生能源利用通用规范》实施后广西居住建筑的节能途径,以南宁市某住宅建筑为例,采用BECS 2023节能设计软件建立典型模型,在固定其他节能影响因素不变的情况下,通过调整外墙和外窗构造做法,得到适宜广西夏热冬暖B区、夏热冬暖A区及夏热冬冷B区典型居住建筑节能设计的围护结构节能构造基本做法,可为新规范在广西的实施和应用提供参考。

In order to study the energy-saving ways of residential buildings in Guangxi after the implementation of General code for energy efficiency and renewable energy application in buildings GB 55015—2021,taking a residential building in Nanning as an example,BECS 2023 energy-saving design software was used to establish a typical model. Under the condition that other en-ergy-saving influencing factors remain unchanged,by adjusting the construction methods of exterior walls and windows,the basic methods of energy-saving construction of envelope structure suitable for energy-saving design of typical residential buildings in Guangxi hot summer and warm winter zone B,hot summer and warm winter zone A and hot summer and cold winter zone B are obtained, which can provide reference for the implementation and application of the new code in Guangxi.
