摘　　要：既有建筑绿色化改造中使用较多的保温材料是EPS板,对外墙保温改造使用EPS板产生的环境效益给出量化结果具有重要意义。采用生命周期评价(LCA)方法,结合实际调研,从EPS生产、销售运输、既有建筑使用EPS、回收运输、回收生产、回收得到PS颗粒等6个方面,用Ebalance软件对EPS板全寿命周期能源消耗及环境排放进行计算。结果表明,在全寿命周期中,1 kg EPS板可减少酸化潜值0.331 kg SO2当量、减少不可再生资源消耗55.0 kg Coal-R当量、减少能源消耗27.7 kgce当量、减少富营养化潜值0.0218 kg PO43-当量、减少全球变暖潜值61.6 kg CO2当量,既有建筑应进行外墙保温改造。EPS board is the most used material in green renovation of existing buildings. It is of great importance to calculate the environmental influence of EPS board in external wall insulation. This article calculates the energy consumption and environment emissions of EPS board in its life cycle by software of Ebalance and in the method of Life cycle assessment （LCA） combined with research,which is in the aspect of EPS production transportation of sales,EPS used in existing buildings, transportation of recycling,recycling production and PS particles, The calculation results estimate that 1 kg EPS can reduce 0.331 kgSO2 eq, 55.0 kgCoal-R eq, 27.7 kgce eq,0.0218 kgPO4^3- eq, 61.6 kgCO2 eq and the renovation of existing buildings is necessary.
