Promotion of sustainability is one of the great challenges facing humankind. Since the building industry started to move toward the promotion of sustainable building in the latter half of the 1980's, various techniques to evaluate the environmental performance of buildings have been developed.
In Japan, a joint industrial/government/academic project was initiated with the support of the Housing Bureau, Ministry of Land, Infrastructure, Transport and Tourism (MLIT), in April 2001, which led to the establishment of a new organization, the Japan GreenBuild Council (JaGBC) / Japan Sustainable Building Consortium (JSBC), with its secretariat administered by the Institute for Building Environment and Energy Conservation (IBEC). JaGBC, JSBC and subcommittees are together working on R&D of the Comprehensive Assessment System for Building Environmental Efficiency (CASBEE). Today, the enhancement and diffusion of CASBEE are being promoted under the MLIT Environmental Action Plan (June 2004) and the Kyoto Protocol Target Achievement Plan (approved by the Cabinet on April 28, 2005). In recent years, several local authorities introduced CASBEE into their building administration. Consequently, environmental performance assessment of buildings in now carried out in many buildings in Japan.

JaGBC/JSBC is continuously developing and updating the CASBEE system.
Since we started the development of CASBEE in 2001, we have compiled the following tools.
- CASBEE for New Construction *
- CASBEE for New Construction (Brief version)
- CASBEE for Existing Building
- CASBEE for Renovation
- CASBEE for Heat Island
- CASBEE for Urban Development *
- CASBEE for an Urban Area + Buildings *
