CASBEE for Cities

CASBEE for Cities


CASBEE for Cities is a rating system for evaluating the environmental performance of cities. It helps to identify environmental, social, and economic characteristics of a city and quantify the effectiveness of its policies.  Intent of this rating system is providing effective rating information to the administrative officers and other stakeholders so that they can share a common understanding regarding the current state of cities and cooperate in order to create a low-carbon society.

How It Works

The CASBEE assessment was developed in accordance with three main concepts: (1) Evaluating a built environment through its entire lifecycle, (2) Evaluating a built environment from the two aspects of quality and environmental load, (3) Evaluating a built environment according to the Built Environment Efficiency (BEE). BEE is an assessment index, which was newly developed based on the idea of eco-efficiency.

Tool Outcome

The evaluation process resulting of the application of this rating system is divided into five grades; Excellent (S), Very Good (A), Good (B+), Fairly Poor (B-) and Poor (C), with each grade represented by a certain BEE value. Besides the certification, the application of CASBEE for Cities can also help in understanding the actual conditions of cities and their progress toward more sustainable development.
