Summary:Discusses the importance of building energy efficiency to explore the significance of the building energy conservation from the construction of the wall， doors， windows， roofing， on the way to building energy conservation and measures to promote the development of building energy-saving technologies to achieve sustainable development in China Key words: building energy efficiency; exterior wall; technology
In recent years， with the "people-oriented" design concept of the proposed residential comfort people have become increasingly demanding， building energy consumption also will 据统计，目前我国建筑能耗约占国民经济总能耗的25%左右，且呈上升趋势。 According to statistics， China's national economy， building energy consumption accounts for about 25% of the total energy consumption， and on the 另一方面，随着建筑能耗的增加和大量空调设备的安装，“城市热岛效应”日益严重，使环境日益恶化。 On the other hand， with the increase in building energy consumption and large air-conditioning installation， "urban heat island effect" is worsening， deteriorating the 我国建筑节能的重点应为：建筑本体的节能、采暖系统节能、提高照明和其他电器的效率、大型公共建筑节能。 China's building energy efficiency should focus on are: ontology building energy-saving， energy-saving heating system， improve the efficiency of lighting and other electrical appliances， large public building energy 随着科学技术的日新月异，能源短缺已不容忽视，节约能源已受到世界性的普遍关注，在我国亦不例外。 With the ever-changing science and technology， energy shortage has not be ignored， a worldwide energy conservation has been widespread concern in China is no 目前，全世界有近30%的能源消耗在建筑物上，长此以往，将严重影响世界经济的可持续发展。 At present， nearly 30% of the world's energy consumption in buildings， the long run， it will seriously affect the world economy and sustainable 因此，能源问题将成为本世纪的热门话题。 Therefore， the energy issue will become a hot topic in this 本文着重讲的是现有建筑节能存在的问题、解决方法与未来的发展方向。 This article focuses on talking about the existing building energy problems， solutions and future direction of
