Decision-Making in Green Building Investment Based on Integrating AHP and COPRAS-Gray Approach

Abstract

Along with the trend of developing green building, problems appear when investors try to make the best decision about their green investment. Due to lack of related research on this problem, this project aims to propose a method for green building investment decision making to help investors make choice wisely. Analytic hierarchy process (AHP) and complex proportional assessment of alternatives-Grey (COPRAS-G) methods are adopted in this study with a case study to illustrate its work mechanism and feasibility in reality. Also, this study will provide an effective and accurate decision-making method to assist the investment in green buildings.
