CASBEE

‍

‍

The Comprehensive Assessment System for Building Environmental Efficiency (CASBEE) is a Japanese sustainability assessment method for buildings. It was developed by the Japan Sustainable Building Council (JSBC) in 1999 and is the most widely used sustainability assessment system in Japan. CASBEE assesses buildings on a wide range of environmental factors, including energy efficiency, water conservation, indoor air quality and environmental impact. CASBEE certification is also a valuable tool for promoting sustainable development in Japan. By encouraging the construction of high-quality environmental buildings, CASBEE certification helps to reduce the environmental impact of the built environment.
