摘要
建筑节能设计要求不断提高是建筑行业发展的趋势。随着国家规范(如《建筑节能与可再生能源利用通用规范》GB 55015—2021)和各地方节能设计规范的推出,夏热冬冷地区建筑节能设计要求越来越高。建筑节能要求的提升预示建筑围护结构做法的更新,屋面、外墙的保温厚度更厚,外窗的选型要求更加严格。该文主要研究《通用规范》相较于上一版国家节能设计规范的围护结构提升比例,以及在性能提升的要求下,对建筑设计中可选用的材料构造进行分析。
The improvement of building energy-saving design requirements has become an inevitable trend in construction industry.There is a higher energy design requirements for building with the development of national codes and local energy design codes.The development of building energy design codes indicates an update in building envelop design.The thermal insulation thickness of the roof and the exterior walls is thicker,and the selection of exterior window is more stringent.This essay mainly studies the improvement of the national codes compared with the previous versions of the national energy design codes,and the material that can be used in the building design under the condition of performance improvement.
