国家标准《民用建筑热工设计规范》(GB 50176-2016)将我国陆地国土划分为五大热工设计分区,其中包含寒冷气候区和严寒气候区,并给出了原则性的设计要求.从建筑节能乃至绿色建筑设计角度来审视,发现既有的热工设计分区过于笼统,单一分区面积太大,分区指标太粗,不利于建筑的被动式太阳能利用和气候适应性设计.本文在回顾建筑气候区划的历史背景基础上,提出了将空气温度的日较差纳入到热工设计分区指标中,以便将现有寒冷气候区和严寒气候区的气候类型做进一步细化,行文中统称为寒冷气候类型,同时给出了每一个寒冷气候类型相应的建筑热工设计对策.本研究可为相关建筑气候区划标准及建筑设计标准规范的修订提供参考.
The Code for thermal design of civil building(GB 50176-2016)divides China's mainland into five thermal design zones, including cold climate zone and severe cold climate zone, and gives the design requirements in principle. From the perspective of building energy conservation and green building design, it is found that the existing thermal design zoning is too general, the single zoning area is too large, and the zoning index is too coarse, which is not conducive to passive solar energy utilization and climate adaptive design of buildings. Based on the review of the historical background of building climate zoning, this paper puts forward that the diurnal temperature range should be included in the index of thermal design zoning, so as to further refine the existing climate types of cold climate area and severe cold climate area, which are collectively called cold climate type in this paper, and at the same time, the corresponding thermal design countermeasures for each cold climate type are given. This study can provide reference for the revision of relevant building climate zoning standards, building design standards and codes.
