为了评价、比较相同节能效果的不同建筑围护结构的环境表现,基于全生命期环境评价理论,论文建立了建筑围护结构全生命期环境影响计算模型,可以用单一结果“环境指标”来计算、表征全生命期5个不同阶段、11个环境影响类型的环境影响。并对居住建筑节能65%的外窗、填充墙进行了环境评价、分析,能够在工程实践中指导部品选型和进一步优化建筑部品的环境表现。
In order to evaluate and compare the environmental performance of different building enveloping structures with the same energy saving effect and based on the life-cycle environmental assessment theory, the paper establishes a calculation model of environmental impact during the whole life cycle of the building enveloping structure, and can use the single result “environmental index” To calculate and characterize the environmental impact of five different stages and 11 environmental impact types during the whole life cycle. And the living building 65% of the energy-saving windows, wall filled with environmental assessment, analysis, engineering practice can guide parts selection and further optimize the environmental performance of construction parts.
