气候变化下我国建筑能耗演化规律研究

BUILDING ENERGY CONSUMPTION PRINCIPIA UNDER CLIMATE CHANGE IN CHINA

通过气候预测获取了我国主要气候区代表城市未来50a（2001～2050年）主要气象参数的集合平均值。分析关键气象参数——气温和太阳辐射在2001—2050期间的变化规律。使用模拟气象分析年数据模式分别制作当前气候条件下（1971—2000年）和未来气候条件下（2021—2050年）的建筑能耗模拟气象年数据，使用DOE2模拟软件对我国各气候区居住建筑在两种不同气候条件下的建筑能耗进行模拟。获得居住建筑单位面积采暖能耗减少、空调能耗增加、总建筑能耗增加的能耗变化规律，分析能耗变化的主要原因，提出未来建筑节能的主要方向是减少建筑空调能耗。

The climatic simulation was used to forecast meteorological data in future from 2001 to 2050 for five cities in China. The five cities represent five different climate types in China. According to the analysis of energy efficient meteorological Year（ AEEMY）, model of meteorological data for building energy simulation, meteorological data for DOE2 was made for simulation. At some time, meteorological data for DOE2 was also made from 1971- 2000 and 2021-2050. A high residential building was simulated respectively in five cities using two meteorological data. The result showed that heating energy is reduce but cooling energy is increase and the increase in cooling energy is greater than the reduce in heating energy. So the total energy of residential building would inereate with the climate warming in future in China.
