External Certification and Evaluation

As a pioneer in J-REIT focusing on mid-sized office buildings, the Investment Corporation (“KDO”) will continue to advance environmental and energy conservation measures as well as efficient energy use for its own office buildings with the support of outside consultants and proactively acquire the following external certification and assessment to promote initiatives for sustainability.

GRESB Real Estate Assessment

GRESB GRESB (Global Real Estate Sustainability Benchmark) is an annual benchmark assessment established primarily by major European pension fund groups in 2009 that measures sustainability performances in the real estate sector.
GRESB attracts a lot of attention because leading institutional investors have joined the high-visibility survey and used GRESB to select and dialogue with investment targets. Therefore, there are many real estate companies, REITs and private funds worldwide that annually participate in the GRESB Real Estate Assessment.
Among many environmental certifications for individual real estate, GRESB is the only assessment that evaluates companies or funds, and GRESB Ratings assigned for participants, which is relative performance ranking (5 Stars are the highest).
KDO earned a "Green Star" designation for the tenth consecutive year by achieving high performance both in “Management Component” that evaluates policies and organizational structure for ESG promotion, and “Performance Component” that assesses environmental performance and tenant engagement of properties owned.
Also KDO acquired the highest “A” Level for Public Disclosure on ESG.
