Environmental Certifications
CASBEE
The Comprehensive Assessment System for Building Environmental Efficiency, or CASBEE, is a Japanese government certification that evaluates and rates buildings’ environmental performance based on their energy and resource efficiency, recycling activity, environmental load, and aesthetic appeal.
CASBEE-certified buildings are scored for their environmental performance in five categories and receive a total environmental performance ranking (from highest to lowest): S, A, B+, B.

BELS and ZEB
BELS is a public evaluation system that assesses the energy efficiency of nonresidential buildings. A third-party organization evaluates the energy efficiency of both new and existing buildings using a Building Energy Index based on Japan’s national building energy efficiency standard. BELS ranks energy efficiency from five stars to one star.
A ZEB-certified building aims to maintain a comfortable indoor environment while reducing its annual primary energy consumption to zero via the use of insulation materials and energy-efficient facilities as a part of transitioning to renewable energy. Based on the BELS system, the ZEB certification ranks buildings (from highest to lowest) as ZEB, Nearly ZEB, ZEB Ready, and ZEB Oriented.
