摘要
能源消耗与气候具有密切关系。一方面能源的开发利用会对气候产生影响;另一方面气候变化又直接影响到能源消耗。建筑部门就是受此影响部门之一。供暖空调能耗在建筑能耗中所占比重较大。通过对我国若干城市近几年的1月平均温度、冬季平均温度与常年值进行比较,利用度日数等气候指标分析了气候变暖对建筑物供暖能耗的影响。同时探讨了气候异常时建筑物空调能耗的变动状况。
Energy consumption is closely related to climate. On one hand , the exploit and utilization of energy source will make climate change;on another hand , the globe climate change might directly impact on energy consumption. The building sector is clearly weather sensitive and is one of the sectors that would be affected by globe climate change. The proportion of the energy consumption of heating and air conditioning in the building energy consumption as a whole is almost 30-50%. The average temperatures of January and winter of several cities in recent years are calculated and compared with the average year temperatures, and the effect of climate warming on building heating energy consumption is analyzed by heating climate index such as degree - days. At the same time , the influence of summer climate abnormality on the change of air conditioning energy consumption is discussed.
