Overview
CASBEE (Comprehensive Assessment System for Built Environment Efficiency) is a Japanese certification program designed to evaluate and promote sustainable buildings. Initiated in 2001 by the Institute for Building Environment and Energy Conservation (IBEC) and supported by Japan's Ministry of Land, Infrastructure, Transport, and Tourism, CASBEE assesses buildings based on energy efficiency, resource efficiency, and overall environmental impact.
The CASBEE Certification for Real Estate evaluates buildings' environmental performance, focusing on management, environmental quality, and energy use. Certificates range from "C" (Poor) to "S" (Excellent), and buildings are encouraged to achieve higher ratings for sustainability.
CASBEE is widely recognized in Japan, with many large corporations participating, including real estate developers and construction companies. The program also collaborates with various international entities to promote green building standards globally. By adhering to CASBEE standards, businesses can reduce environmental impact, increase property value, and promote healthier living spaces.
Requirements & Verification
Evidence Requirements
Applicants must submit documentation demonstrating the building's environmental performance across CASBEE's assessment categories, including energy consumption data, resource use records, indoor environmental quality evidence, and building management practices. Assessment is conducted by an accredited CASBEE certification body using the CASBEE for Real Estate tool and supporting documentation provided by the building owner or manager.
Prerequisites
Assessment Process
Certification is conducted by IBEC-accredited third-party certification bodies. Assessors evaluate submitted documentation against the CASBEE for Real Estate criteria, covering environmental quality (Q) and environmental load reduction (LR) across multiple sub-categories. The assessment results in a BEE (Built Environment Efficiency) score and a rating from C (Poor) to S (Excellent). On-site verification may be required depending on the certification body and building type.
Renewal & Compliance
CASBEE certifications are typically valid for a defined period and require periodic reassessment to maintain certification status. Building owners must resubmit updated performance data and documentation to an accredited certification body. Specific renewal intervals and requirements may vary by certification body and building type.

Employer Recognition
Consider Alternatives If...
Organizations outside Japan may find limited market recognition compared to globally dominant standards like LEED or BREEAM. Those seeking a widely internationally recognized credential should consider whether CASBEE's primarily Japan-focused recognition meets their needs.
