随着经济及城市化的快速发展,城市化过程中建筑能耗问题日益突出,东北严寒地区建筑面积达到20亿平方米,供暖能耗占建筑总能耗40%左右,建筑节能潜力巨大,东北严寒地区在国家“节能减排”中的作用巨大,能源短缺和环境恶化已经成为社会的热点问题,东北严寒地区具有地域广阔、气候特征不同、建筑特点和居民生活习惯差异很大、供暖时间长、负荷大等特点,建筑能耗以解决冬季保温为主,夏季隔热为辅,在《国家中长期科学和技术发展规划和纲要(2006-2020)》中明确提出“可再
With the rapid development of economy and urbanization, the issue of building energy consumption in the urbanization process has become increasingly prominent. The construction area in northeast cold area reaches 2 billion square meters, the heating energy consumption accounts for about 40% of the total building energy consumption, and the potential for building energy conservation is huge. Severe cold areas play an important role in the national ”energy saving and emission reduction“, energy shortage and environmental deterioration have become a hot issue in society. In the northeast cold region, there are vast territories, different climate characteristics, great differences in building characteristics and residents’ living habits, and heating Long time, heavy load and so on. The building energy consumption mainly solves the problem of winter insulation and summer heat insulation. It clearly states in the ”National Medium and Long-term Scientific and Technological Development Plan and Outline (2006-2020)“ that ”
