Abstract
The midpoint impact assessment methodology and several weighting methods that are currently used by most building Life cycle assessment LCA researchers in China still have some shortcomings In order to make the evaluation results have better temporal and spatial applicability the endpoint impact assessment methodology was adopted in this paper Based on the endpoint damage oriented concept four endpoints of resource exhaustion energy exhaustion human health damage and ecosystem damage were selected according to the situation of China and the specialties of the building industry Subsequently the formula for calculating each endpoint the background value for normalization and the weighting factors were defined Following that an endpoint damage oriented model to evaluate the life cycle environmental impact of buildings in China was established This model can produce an integrated indicator for environmental impact and consequently provides references for directing the sustainable building design
