Fuzzy Logic and Analytic Hierarchy Process–Based Conceptual Model for Sustainable Commercial Building Assessment for India

Abstract

The impact of buildings on the environment has created the need for green or sustainable buildings, which aim to reduce energy and resource consumption. Sustainable building assessment methods have emerged in recent years as a means to evaluate the performance of buildings across a broad range of sustainability considerations. This research presents a conceptual model for the assessment of sustainable commercial buildings with the use of fuzzy logic and the analytic hierarchy process (AHP). It covers 100 sustainability criteria. The proposed building evaluation model depends on two types of parameters: endogenous (constants: global weights of criteria) and exogenous (variables: performance score of building for each criterion). A building’s sustainability score reflects the interplay between these two parameters. Global weights of criteria can be developed through AHP. The performance scores of criteria can be determined through fuzzy logic. The proposed approach of building evaluation can produce significant benefits that are not likely to result from conventional practices.
