北京市“十三五”时期民用建筑节能潜力研究

STUDY ON POTENTIAL ENERGY CONSERVATION CAPACITY OF CIVIL BUILDINGS IN BEIJING DURING THE 13TH FIVE-YEAR PERIOD

运用"自下而上"节能措施法,通过新建建筑采暖节能、既有建筑节能改造、可再生能源建筑应用、公共建筑节能监管等节能措施,得到"十二五"外推、强化政策以及极端政策三种情景下,将分别产生节能潜力391.31,602.95和804.41万t标煤。采用"自上而下"能耗分析法,得到由人口总量和建筑面积总量控制能够产生的节能潜力236.67万t标煤,仅次于城镇新建建筑采暖节能潜力。因此,在"十三五"建筑节能工作中,不仅要重视建筑节能措施本身,还要考虑相关宏观因素的作用,从更大范围和更广视角来对待建筑节能工作。

Three potential energy conservation capacities of 3.9131mt, 6.0295mt and 8.0441mt standard coal will be realized respectively under extrapolation, strengthening and extreme policies established during the 12th Five-Year Period, by using bottom-up energy-saving method and adopting such energy saving measures as new building heating energy conservation system, energy-saving reconstruction of existing building, application of regenerative energy building and supervision of energy conservation of public buildings, etc. Bottom-up energy consumption analysis indicates that the potential energy conservation of 2.3667mt standard coal realized through control of total population and building area is slightly less than the potential energy conservation capacity of buildings newly constructed in cities and towns. For building energy conservation during the 13th Five-Year Period, emphasis shall be made not only on building energy-saving measure itself, but also on effect of related macro factors, so asexecute building energy conservation in wider scope and vision.
