Author(s) : LIU M., LI B., YAO R.

Summary

Climate change, air pollution, ozone depletion and other environmental issues are worldwide hot points which makes make development become a focus. Green building is a sustainable label in building industry and since 1990s, the developed countries have developed respective building environmental assessment system based on their own background. Firstly, this paper introduces two main methods for building environmental assessment system, and they are checklist and life cycle assessment. After analyzing the existing environmental assessment system, this paper summarizes the main shortages and puts forward a new assessment methodology-exergy assessment. Exergy is a thermodynamic term and widely used in energy field. It can be used to measure resource quantity and quality. Thus, exergy is introduced to measure building environmental impacts by separating the environmental impacts into three parts: energy-related resource, non-energy-related resource and environmental pollution. The paper gives a brief presentation on the measurement of the three parts' environmental impacts. Finally, the paper develops a building environmental assessment system based on exergy and life cycle analysis.
