The Model Research of LCA Economic Evaluation of Building Exterior Wall

Abstract

Building exterior wall full life cycle assessment is the whole life cycle of various building materials, components production, planning, design, construction, operation and disposal phases in the material energy flow generated by the economic benefit, social benefit and environmental benefit,which is the sum of the evaluation. Full life cycle assessment is a very broad concept, it is to do the comprehensive analysis of the life cycle process, including the environmental systems, energy systems, natural resources, human health and so on. various aspects are to assess the influence of the potential, and ultimately to find ways to improve. Exterior wall full life cycle of economic evaluation model is established, the core content is a comprehensive economic evaluation of the scheme of building external wall structure, economic benefit evaluation of different exterior design, which provides the strong basis for the adoption of reasonable solution.
