转变经济发展方式 建筑节能任重道远  
“ 建筑节能要合理改造已有建筑,大力发展绿色建筑、智能建筑,最大限度地节能、节地、节水、节材。”7月19日,在温家宝总理主持的国家应对气候变化及节能减排工作领导小组会议上,将建筑节能列入“十二五”期间重点领域节能减排之中,要求加大工作力度。由此可见,建筑节能作为全国节能减排战略中的重要内容之一,任重道远。

       为提高能源利用效率,降低建筑能耗,减少CO2排放,减缓地球温室效应,从1986年开始,我国就陆续开展了新建建筑节能、既有建筑节能改造、可再生能源建筑规模应用、发展推广绿色建筑等一系列工作,全面推进建筑节能工作,并取得了一定的成效,为全国节能减排作出了重要贡献。

       但是,我们仍要看到当前建筑节能还有许多工作需要做。就既有建筑来说,我国既有建筑存量大、能耗高,尤其是北方采暖地区冬季的供暖能耗,占到北方城镇建筑能耗的40%。“十一五”期间我国完成了1.8亿平方米既有建筑的节能改造,虽然超额完成了国家1.5亿平方米的任务,但是我国北方具备改造价值的老旧住宅达12亿平方米。按照财政部、住房和城乡建设部的要求,“十二五”期间各地的工作目标也只是完成老旧住宅节能改造任务的35%。由此可见,既有建筑节能改造是一项量大、任务重的长期工作。从我国绿色建筑的发展来看,虽然目前发展势头良好,各地不论是政府还是企业都十分重视绿色建筑,积极申报和评选不同星级的绿色建筑。但是与发达国家相比,我国起步较晚,还处于示范推广的初期和起步阶段,符合标准的绿色建筑数量少、规模小、发展不平衡,要大面积地建设绿色建筑,我们还有很长的路要走。

       “十二五”期间是我国转变经济发展方式、加快经济结构战略性调整的关键时期。建筑节能作为我国减缓和适应全球气候变化、促进可持续发展的重要举措,任重道远。
