CASBEE (Comprehensive Assessment System for Built Environment Efficiency/Building Environment Efficiency) is a method for assessing and rating the environmental performance of buildings and the built environment in Japan under the auspice of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
Certification for CASBEE for Real Estate is a system in which a third party examines and certifies assessment results prepared in accordance with CASBEE for Real Estate, one of the CASBEE certification systems. It was developed to promote the use of the results of building environmental assessments in CASBEE as an environmental assessment in the real estate market. The assessment criteria have been developed focusing on items that are strongly related to real estate evaluation so that people engaged in real estate development and transactions can utilize CASBEE. The assessment items are made up of 21 items in five categories of “Energy/Greenhouse Gas,” “Water,” “Resource Utilization/Safety,” “Biodiversity/Site” and “Indoor Environment.” CASBEE takes into account the same environmental performance items that are attracting attention from companies in Japan and abroad as common international items proposed by the UNEP SBCI (United Nations Environment Programme Sustainable Buildings and Climate Change Initiative). Of the properties owned by MPR, the following properties have acquired certification.

BELS (Building-Housing Energy-efficiency Labeling System) is a third-party certification system that gives ratings to houses and buildings that respond to the obligation to make efforts to display energy-saving performance based on the Act on the Rational Use of Energy. Houses and buildings are assessed based on the coating material performance and the BEI (Building Energy Index) value calculated using the amount of primary energy consumption based on the building energy consumption performance standard stipulated by the national government.
Assessment and labeling based on this system is to be carried out by registered housing performance evaluation organizations, designated confirmation inspection organizations, or registered building investigation organizations that are members of the Evaluation Association of Japan, and that have been notified as organizations that carry out BELS operations. The assessment/labeling under this system is conducted by organizations that have submitted notification as an organization which carries out BELS related operations among the registered housing performance assessment organizations, designated confirmation inspection organizations, or registered building investigation organizations that are members of the Association for Housing Performance Evaluation and Indication. The Certification rank is represented by the number of stars (1star - 5 stars). The following MPR properties have received certifications.

DBJ Green Building Certification is a certification system established in April 2011 by the Development Bank of Japan to support environmentally and socially conscious real estate (green building). In addition to the environmental performance of the subject property, a comprehensive assessment that includes the various responses to stakeholders such as disaster prevention and consideration to the community, as well as the consideration for social requests by stakeholders and responses to the diversifying tenant needs is used to assess and certify the real estate needed by society and for the economy.
