【 摘 要 】

The use of natural resources for building construction represents, in terms of mass, one of the biggest challenges in resource consumption. On the other hand, construction and demolition waste is one of the most important waste streams generated in the EU, about 25% - 30% of all waste generated in the EU, and consists of numerous materials with potential for recycling. Recently, a research project EFIResources was completed, which focussed on the development of a performance based approach for sustainable design, enabling to assess resource efficiency of buildings, in the early stages of building design, and supporting European policies related to resource efficiency and circular economy. Therefore, the main aim of this paper is to present the developed approach, which is based on the benchmarking of the environmental performance of buildings, in a life cycle perspective. Moreover, this paper includes a discussion of the different methods that are available for the allocation of credits and/or debits due to the recycling process, between the system producing the secondary materials and the system receiving them, in line with current EU policies.
