Allocating weightage to sustainability criteria’s for performance assessment of group housing developments: Using fuzzy analytic hierarchy process

Abstract

Sustainability assessment is a method to assess the effectiveness of sustainability performance. The construction industry largely acknowledges Green Building Rating Systems (GBRS) as a tool for evaluating sustainability performance. With an emphasis on group housing constructions in India, the present study created a methodology for evaluating sustainability performance. An in-depth analysis of the GBRS and published literature, followed by expert interviews, created a methodology with five building life cycle stages and fifteen criteria’s focusing on sustainability. Stakeholder perception was collected, and the data was assessed using the Fuzzy Analytic Hierarchy Process, to determine the priority weight of sustainability criteria and sub-criteria (FAHP). The development of a comprehensive system to account for sustainability on both the intergenerational and intragenerational levels for sustainability assessment is required. This study serves to be the first study to develop a comprehensive sustainability assessment system specific to group housing in India throughout the building life cycle stages.
