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.

About CASBEE

CASBEE Sapporo
Aiming to promote environmentally-friendly buildings, CASBEE Sapporo (Sapporo Building Environmental Consideration System) is a system that requires owners of new buildings and buildings undergoing renovations with a total area of 300m2 or more to conduct self-evaluations of the environmental performance of its buildings, and submit the evaluation results (a building environmental consideration plan) to Sapporo City.

CASBEE Wellness Office
CASBEE Wellness Office Certification evaluates building specifications, performance, and initiatives that support the health, well-being, and comfort of the building occupants. In addition to factors that directly affect the health and comfort of people working in the building, the assessment also covers elements that contribute to improved productivity, as well as safety and security.

BELS

The Building-housing Energy-efficiency Labeling System, or BELS, is a Japanese government evaluation system that assesses the energy efficiency of buildings. A third-party organization evaluates both new and existing buildings using a Building Energy Index based on Japan’s national energy-efficiency standards. Until March 2024, BELS ranked energy efficiency from five stars to one star, with buildings receiving two or more stars classified as energy efficient buildings under 2016 standards. From April 2024 onwards, the energy efficiency ranking has widened to seven stars, with buildings receiving one or more stars classified as energy efficient buildings according to 2024 standards.

About BELS

ZEB

A ZEB-certified building aims to maintain a comfortable indoor environment while reducing annual primary energy consumption to net zero. This is achieved through high performance insulation, energy-efficient equipment, and the integration of renewable energy sources. Under the BELS framework, ZEB certification is categorized into four levels (from highest to lowest): ZEB, Nearly ZEB, ZEB Ready, and ZEB Oriented.
