我国严寒和寒冷地区涵盖北京、天津、河北、黑龙江、吉林、辽宁、内蒙古、宁夏、陕西、山西、甘肃、新疆、青海、山东、河南等15个省、自冶区、直辖市。北方地区气候特点突出,冬季采暖期长,是我国建筑耗能以及建筑节能的重点地区。北方地区建筑节能工作的重中之重无疑是供暖节能,其重要抓手则是供热计量改革,这同时又紧密关系到围护结构的保温改造。我国规模化实施北方地
China’s cold and cold regions cover 15 provinces, autonomous regions and municipalities directly under the jurisdiction of Beijing, Tianjin, Hebei, Heilongjiang, Jilin, Liaoning, Inner Mongolia, Ningxia, Shaanxi, Shanxi, Gansu, Xinjiang, Qinghai, Shandong and Henan. Outstanding features of the climate in the north, long heating period in winter, is China’s building energy consumption and energy efficiency of key areas. Building energy efficiency in the northern region is undoubtedly the most important work of energy-saving heating, the important starting point is the heating measurement reform, which is also closely related to the envelope insulation transformation. China’s large-scale implementation of the north
