严寒和寒冷地区居住建筑节能设计专篇浅析

Analysis on Design Specification for Energy Efficiency of Residential Buildings in Severe Cold and Cold Zones

建筑工程施工图设计说明节能专篇,是施工图设计文件的重要组成部分,是《建筑工程设计文件编制深度规定》(2008年版)要求的内容,是工程项目建设过程中进行材料采购、非标准设备制作和施工的重要依据。针对实际工作中建筑节能设计专篇的普遍问题,从节能设计依据、外墙保温体系、体形系数、窗墙面积比、室内外温度参数、露点温度、热桥部位内表面温度、保温材料性能指标要求、外门窗和透明幕墙的性能指标要求、建筑节能设计结论等方面,分析阐述严寒和寒冷地区居住建筑建筑专业施工图设计说明节能专篇的内容及其内在的技术、政策条件和要求。

Building energy efficiency design specification,which is required in the Regulations for the Depth of Architectural Engineering Design Documentation（the 2008 Edition）,is an important part of the construction drawing design documents and also an important basis for material procurement,non-standard equipments production and engineering construction in the process of project construction. Based on common problems of design specification for building energy efficiency,the contents and potentially technical are analyzed and summarized,as well as the policy conditions and requirements of the energy efficiency design specification of residential buildings in severe cold and cold zones from such aspects as energy efficiency design basis,external wall thermal insulating systems,shape coefficient,area ratio of window to wall,indoor and outdoor temperature parameters,dew-point temperature,inner surface temperature of thermal bridge positions,performance indicators of heat insulating materials,performance indicators of door,window and transparent curtain wall and energy efficiency design conclusions.
