BEPAS—a life cycle building environmental performance assessment model

This paper presents a building environmental performance analysis system—BEPAS, which was developed based on the life cycle assessment (LCA) framework. In BEPAS, environmental impacts were investigated in three main aspects of a building that were closely related to environmental performance—building facilities, building materials and location. In addition, a set of environmental databases were developed, covering the environmental performance profiles of these environmental aspects. The BEPAS can be used to assess the environmental performance of a new or existing building. This paper also discusses a case project in order to illustrate the assessment procedures and test the effectiveness of the system in application.
