1. Overview of Assessment Certification in "CASBEE for Real Estate"
   CASBEE is a system to comprehensively assess and rank the quality of buildings including indoor comfort and considerations to the landscape, in addition to environmental considerations through energy saving or use of materials and equipment with less environmental load. It has been promoted and operated by the Institute for Building Environment and Energy Conservation (hereafter referred to as "IBEC") under the leadership of the Ministry of Land, Infrastructure, Transport and Tourism. CASBEE for Real Estate has been developed with the aim of utilizing the results of CASBEE environmental assessment on buildings for real estate assessment, and its assessment criteria have been established exclusively around items closely related to real estate assessment based on the assumption that they will be used by stakeholders involved in development and transactions of real estate.
   Moreover, the assessment certification in CASBEE for Real Estate is conducted by a third-party institution designated by IBEC for the purpose of operating and promoting CASBEE fairly, as well as securing credibility of assessment results and transparency. Buildings assessed as having appropriate performance under the assessment criteria are rated in five stages comprised of "Rank S (Excellent)," "Rank A (Very Good)," "Rank B+ (Good)," "Rank B- (Slightly Poor)" and "Rank C (Poor)."
