许多发达国家在能源危机的冲击下掀起了节能的浪潮,建筑设计也相应提出了节能建筑设计。建筑节能已成为当今世界各国普遍关注的问题。近年来,我国政府对节约能源的工作给予了极大的重视,在建筑业颁布的节约能源法中明确指出“建筑物的设计和建造应当提高保温隔热性能,减少采暖、制冷、照明的能耗”。目前,发达国家建筑能耗占国家总能耗30％～40％,其中建筑使用能耗约占20％,建筑业材料、设备和施工用能约占10％。我国建筑能耗占国家总能耗25％,其中建筑使用能耗约占总能耗9％～11％。
Many developed countries have set off a wave of energy conservation under the impact of the energy crisis and the architectural design has put forward energy-saving building design accordingly. Building energy efficiency has become a common concern of all countries in the world today. In recent years, our government has given great importance to the work of energy conservation. In the energy conservation law promulgated by the construction industry, it is clearly stated that “the design and construction of buildings should improve the performance of heat insulation and insulation, reduce the energy of heating, cooling and lighting Consumption. ” At present, the building energy consumption in developed countries accounts for 30% -40% of the total national energy consumption, of which energy consumption in construction accounts for about 20% and that of construction materials, equipment and construction accounts for about 10%. China’s building energy consumption accounts for 25% of the country’s total energy consumption, of which the building’s energy consumption accounts for about 9% to 11% of the total energy consumption.
