Activities and Achievements (excerpt)
■しかくBEST
BEST (Building Energy Simulation Tool) is an effective computer simulation program for building energy research and evaluation. BEST is capable to analyze not only the performance of building envelope and HVAC system, but also lighting, water use, and additional equipment loads such as elevators.
■しかくCASBEE
CASBEE (Comprehensive Assessment System for Built Environment Efficiency) is a method for evaluating and rating the environmental performance of buildings and the built environment.
CASBEE has been designed to both enhance the quality of people's lives and to reduce the life-cycle resource use and environmental loads associated with the built environment, from a single home to a whole city. Consequently, various CASBEE schemes are now deployed all over Japan and supported by national and local governments.
■しかくJ-CAT
J-CAT (Japan Carbon Assessment Tool for Building Lifecycle) is a tool (calculation software and manual) developed by the Zero Carbon Building Promotion Committee to calculate GHG (greenhouse gas) emissions, including CO2, throughout the entire building lifecycle. Its first edition (trial version) was published in May 2024 and the second edition (official version) was launched at the end of October 2024.
