【摘要】：资源耗竭潜力因子ADP(Abiotic Depletion Potential)是目前评价产品生命周期资源消耗水平的常用因子,但不够细致全面,存在一定的局限性。考虑到资源特点多样性,将资源分为可再生资源、可回收的不可再生资源和不可回收的不可再生资源3类,并针对性地提出资源耗竭度RDD(Resource Depletion Degree)和资源耗竭当量系数EF(Equivalent Factor)的计算公式,构建评价框架对自然资源耗竭性进行分类评价。将评价方法运用于建筑行业某住宅,得到其物化阶段5种资源消耗水平,验证了该评价方法的可行性及RDD因子相对于ADP因子在资源耗竭评价方面的优越性。
[Abstract]:Resource depletion potential factor (ADP (Abiotic Depletion Potential) is a common factor in evaluating the level of resource consumption in product life cycle, but it is not comprehensive enough and has some limitations. Taking into account the diversity of resources, which are classified into three categories: renewable resources, recyclable non-renewable resources and non-recyclable non-renewable resources, The calculation formulas of resource exhaustion degree (RDD (Resource Depletion Degree) and resource exhaustion equivalent coefficient (EF (Equivalent Factor) are put forward, and the evaluation framework is constructed to evaluate the natural resource depletion. The evaluation method is applied to a residential building in the construction industry and five levels of resource consumption are obtained in the physical and chemical stages. The feasibility of the evaluation method and the superiority of the RDD factor compared with the ADP factor in the evaluation of resource depletion are verified.
