香港建筑能耗现状特征分析

Present Situation and Characteristics of Building Energy Consumption in Hong Kong

随着经济的发展,香港的建筑行业也迅速发展.建筑面积的持续增长,在改善人们居住条件的同时也导致了建筑能耗的大量攀升.为了实现香港经济的可持续发展,有必要对香港地区建筑能耗现状进行研究.介绍了香港建筑的发展,在此基础上详细介绍了香港地区建筑能耗的历史发展趋势,并对建筑能耗的类别进行了详细的分类及分析.通过分析可看出建筑能耗在香港地区能源消费中占有重要的地位,为了社会的可持续发展,建筑节能势在必行,因此本文也对香港地区建筑节能的现状和节能潜力进行了分析.

With the growth of economy, the construction industry of Hong Kong has developed fast. The building stock in Hong Kong has been expanding consistently in the past several decades to meet the needs of improving the living condition, which on the other hand results in a sharp increase of building energy consumption. As energy supply is essential to the continuous growth of economy, it is necessary to study the present building energy consuming condition. In this paper, the construction industry of Hong Kong is briefly reviewed. Then the building energy in Hong Kong is discussed in depth. Based on the analysis, the significance of buildings in respect of energy use in the whole Hong Kong is ascertained, and the need for improvement on the energy performance of buildings is unquestionable for the sustainable development of the society. Lastly, the present situation of the building energy saving and its potential for improvement are analysed.
