Abstract

Focusing on the evaluation items of CASBEE（Comprehensive Assessment System for Built Environment Efficiency）, we measured the importance of total of 20 items for environmental performance using conjoint analysis. It was confirmed that consumers place importance on environmental performance, where they can feel the merits of “comfort” and “convenience”. Additionally, we compared the level of each performance evaluation item of the actually supplied apartment buildings with the importance of consumers, and made a proposal for the spread of the environmental certification system.
