CASBEE Certification System

CASBEE is broadly used by many construction companies, design offices, real-estate developers, etc. as a voluntary-basis evaluation tool for checking the environmental performance of their buildings.
Reflecting the growing needs for a certification of the assessment result, we started the CASBEE Certification System in 2005.
As of April 2015, the total number of the CASBEE certified buildings is over 450. The list of buildings are shown in the following links.

All the information is written in Japanese. we are now preparing for the English list.

Utilization by Japanese local governments

As of March 2015, 24 Japanese local governments have introduced CASBEE system as their environment measures for encouraging green buildings. The governments require the building owners to report the assessment results by CASBEE before its construction.

The number of reports submitted to the local governments is over 14000 (as of March 2014).
The details are shown in Table 1.

CASBEE Accredited Professional Registration System

CASBEE is based on assessment as quantitative as possible, but it includes qualitative items in the system. In such items, it requires specific expertise and knowledge for its assessment. So we established CASBEE Accredited Professional Registration System in 2005.
There are three licences in CASBEE-APs, 1] Building AP, 2] Detached House AP and 3] AP for Market Promotion.

To become a CASBEE-APs, it is needed to take the training courses, pass the examination and complete registration. The candidate for Building AP must be Japanese first-class architect to take the examination.
For now, There are over 12000 CASBEE-APs in total. (as of March 2015)
