CASBEE Family and tools

CASBEE is comprised of assessment tools tailored to different scales: construction (housing and buildings), urban (town development) and city management. These tools are collectively known as the CASBEE Family.

Tools for city scale

1) CASBEE for Cities

Conducting city assessments and disclosing those results to the public are important for supporting citizens' understanding of the actual condition of their city. Such assessment and disclosure could introduce a market mechanism that can be expected to provide city governments with strong incentives to improve their city conditions and also recognize that local policy and strategy can be the most appropriate way to address specific urban and environmental problems.
CASBEE for Cities is a system for comprehensively evaluating the environmental performance of cities, using a triple bottom-line approach of "environment," "society" and "economy." We have developed this new tool in 2011 with the cooperation of the Promotion Council of Low Carbon Cities (PCLCC) (Secretary: The Regional Revitalization Bureau of Cabinet Secretariat). The PCLCC consists of Eco-Model Cities and other local governments, government-related organizations, relevant ministries and agencies, private companies and other bodies in Japan.
CASBEE for Cities measures the current BEE of the city concerned and estimates the future BEE after the implementation of policies. By comparing the two values, CASBEE for Cities quantitatively evaluates (estimates) the effectiveness of city policies and presents the results in an easy-to-understand format. We hope this new tool will help administrative officers and other stakeholders to share a common understanding of the current state of cities and cooperate in setting and pursuing goals in order to create a low-carbon society.

2) CASBEE for Cities -Pilot version for worldwide use

CASBEE for Cities (Pilot version for worldwide use) is a tool specifically developed for city-scale assessment applicable to various types of cities in both developing and developed countries around the world. Thus assessment items and indicators for the tool were carefully selected by referring to previous studies and documents published by international organizations such as the UN's Sustainable Development Goals (SDGs) indicators and ISO 37120 (Sustainable development of communities - Indicators for city services and quality of life). As most of the indicators implemented in CASBEE are based on SDGs indicators and ISO 37120 indicators, the tool users such as local governmental officers, citizens and other stakeholders can understand the actual conditions of their cities and progress toward achieving global SDGs. Such visualization of city status would help tool users in detecting the problems to be urgently solved in their cities and to make their cities more livable and sustainable.This tool is currently a pilot version, and the official version will be released in the near future.
