基于生命周期理论评价建筑物能耗及环境影响

生命周期评价方法（LCA）能够分析整个建筑物各个环节对全社会的能耗和环境的影响，其分析结果可使项目各参与者清楚地了解建设项目各环节的能耗和环境影响。借助生命周期评价方法研究江苏某教学楼从原材料生产到建筑物修建完成整个过程中的能耗及环境影响，发现合理地利用分析结果有助于优化项目的设计、生产和运输方案。从节约资源、能源，保护环境的角度出发提出了扩大生命周期评价方法应用领域的研究方向。

Assessment of building energy consumption and environmental impact based on life cycle theory

Life cycle assessment （LCA） is used to analyze the impacts of the building on energy consumption and environment of the society. The analysis results assist the participants to understand impacts of each stage of the construction projects on energy and environment. The energy consumption and environmental impact of a teaching building in Jiangsu province were conducted with life cycle assessment from its raw material production to the completion. The assessment results help to optimize the scheme of design, production or transportation. The research direction was also proposed to extend the life cycle evaluation methods from the view of resource and energy saving and environment protection.
