在国外,建筑业与钢铁、汽车工业被并列为国民经济的三大支柱。在能源消费上,建筑能耗也占很大比重。许多国家都非常强调建筑节能。现就我国建筑能耗和节能方向作一些分析和探讨。我国房屋建筑的能源消耗房屋建筑的能耗可分两部分:一是建造能耗,包括建筑材料的生产、运输以及建筑施工、安装中的能耗,二是使用能耗,包括建筑物采暖、通风、空调、照明以及厨房烹饪、供水、消防及各种家用电器等的能耗。
In foreign countries, the construction industry and the steel and automobile industries are listed as the three pillars of the national economy. In energy consumption, building energy consumption also accounts for a large proportion. Many countries have emphasized building energy efficiency. Now we will make some analysis and discussion on the direction of building energy consumption and energy conservation in our country. The energy consumption of China’s housing construction can be divided into two parts: the first is the construction of energy consumption, including the production and transportation of building materials, energy consumption in construction and installation, and the second is the use of energy, including building heating. Ventilation, air conditioning, lighting and energy consumption in kitchen cooking, water supply, firefighting and various household appliances.
