What is CASBEE Kitakyushu? CASBEE Kitakyushu is a type of “Comprehensive assessment system for building environmental efficiency” that combines nation level assessment based on CASBEE for New Construction (brief version) and assessment specific to Kitakyushu with prioritized points. Academic experts and people from related departments discussed in the board to extract corresponding items from CASBEE for New Construction (brief version) as prioritized points.
