轉變經濟發展方式 建筑節能任重道遠  
“ 建筑節能要合理改造已有建筑,大力發展綠色建筑、智能建筑,最大限度地節能、節地、節水、節材。”7月19日,在溫家寶總理主持的國家應對氣候變化及節能減排工作領導小組會議上,將建筑節能列入“十二五”期間重點領域節能減排之中,要求加大工作力度。由此可見,建筑節能作為全國節能減排戰略中的重要內容之一,任重道遠。

       為提高能源利用效率,降低建筑能耗,減少CO2排放,減緩地球溫室效應,從1986年開始,我國就陸續開展了新建建筑節能、既有建筑節能改造、可再生能源建筑規模應用、發展推廣綠色建筑等一系列工作,全面推進建筑節能工作,并取得了一定的成效,為全國節能減排作出了重要貢獻。

       但是,我們仍要看到當前建筑節能還有許多工作需要做。就既有建筑來說,我國既有建筑存量大、能耗高,尤其是北方采暖地區冬季的供暖能耗,占到北方城鎮建筑能耗的40%。“十一五”期間我國完成了1.8億平方米既有建筑的節能改造,雖然超額完成了國家1.5億平方米的任務,但是我國北方具備改造價值的老舊住宅達12億平方米。按照財政部、住房和城鄉建設部的要求,“十二五”期間各地的工作目標也只是完成老舊住宅節能改造任務的35%。由此可見,既有建筑節能改造是一項量大、任務重的長期工作。從我國綠色建筑的發展來看,雖然目前發展勢頭良好,各地不論是政府還是企業都十分重視綠色建筑,積極申報和評選不同星級的綠色建筑。但是與發達國家相比,我國起步較晚,還處于示范推廣的初期和起步階段,符合標準的綠色建筑數量少、規模小、發展不平衡,要大面積地建設綠色建筑,我們還有很長的路要走。

       “十二五”期間是我國轉變經濟發展方式、加快經濟結構戰略性調整的關鍵時期。建筑節能作為我國減緩和適應全球氣候變化、促進可持續發展的重要舉措,任重道遠。
