Evaluation and Sensitivity Analysis of the Energy Consumption of the Chinese Construction Sector Based on Input-Output LCA Model

  • 摘要: 建设活动消耗了大量能源,研究建筑业能耗测算方法并分析其影响因素有助于建筑业的节能减排. 采用投入产出生命周期评价模型测算建筑业能耗,分析建筑业能耗对部门间联系、部门能源强度和建筑业规模等因素变化的敏感性,提出部门对建筑业能耗的技术责任系数和结构责任系数,以判断部门在降低建筑业能耗中的责任. 结果表明,2010年我国建筑业能耗为1.07×109 t(以标准煤计);技术责任系数最大的部门是黑色金属冶炼及延压(0.489 8),其次是非金属矿物制品(0.479 8)和化工(0.211 8)等;除建筑业外,结构责任系数较大的部门包括非金属矿物制品(0.276 4)和黑色金属冶炼及延压(0.246 0)等;建筑业能耗对黑色金属冶炼及延压(0.243 8)和非金属矿物制品(0.203 4)等部门能源强度的变化最敏感. 降低建筑业能耗应注重促进高能耗建材生产节能、强化建设活动科学管理、推广高性能低能耗材料应用、提高基础设施建设水平和深化住房市场化改革等方面.
