基于LCA研究建筑保温的节能减排效益

STUDY ON THE BENEFITS OF ENERGY CONSERVATION AND EMISSION REDUCTION BASED ON LIFE CYCLE ASSESSMENT

建筑保温是建筑节能重要途径之一,利用生命周期评价方法对某一办公建筑保温进行生命周期节能减排效益研究和生命周期成本评估,结果表明,保温后节能4379.94MJ/m2,大气污染物CO2、SO2、NOX、CO、CH4、PM10分别减排367.749、3.424、2.238、0.534、2.762、7.152kg/m2,具有良好的节能减排效益,生命周期成本减少了294.48元/m2,具有良好的经济性。

Building insulation is one of important means of building energy conservation,life cycle assessment method(LCA)is used to study the life cycle benefits of energy conservation and emission reduction and cost of building insulation using EPS as thermal insulation material,the results show that the amount of energy conservation is 4 379.935 MJ/m2,the amount of emission reduction of CO_2,SO_2,NO_X,CO,CH_4 and PM_10 are 367.749,3.424,2.238,0.534,2.762 and 7.152 kg/m2,the amount of life cycle cost reduction is 294.48Yuan/m2,building insulation has very good benefits of energy conservation and emission reduction and economic benefits.
