Green construction assessment for environmental management in the construction industry of Hong Kong

Abstract There is a growing concern on environmental impacts resulted from construction activities. Environmental assessment (EA), a tool for reviewing, monitoring, checking and evaluating environmental performance for the construction industry, has been advocated. Although there is a plethora of environmental assessment tools, most of them are not designed for construction. This paper proposes a system called “green construction assessment” (GCA) for construction. Two types of environmental indicators are embraced: management performance indicators (MPIs) and operational performance indicators (OPIs). Using a multi-criteria decision system, the non-structural fuzzy decision support system (NSFDSS), the weights for each criterion and sub-factors are developed, producing a yardstick for assessing the environmental performance for construction activities at the construction stage. Further, three projects were used in the verification of the GCA model. Positive results have been obtained that verifies the reliability of the proposed GCA model for construction in Hong Kong.
