CASBEE® (Comprehensive Assessment System for Built Environment Efficiency) is an evaluation system that ranks buildings and structures in terms of their environmental performance. In addition to each building's ability to reduce its environmental impact across a variety of areas including energy and resource conservation as well as recycling, this system comprehensively evaluates the environmental performance of each building and structure including its aesthetic appeal.

Under the DBJ Green Building system, the Development Bank of Japan (DBJ) certifies real estate properties with high environmental and social awareness, based on five evaluation ranks (one star "★" to five stars "★★★★★"), using a comprehensive scoring model developed independently by DBJ.

BREEAM In-Use certification is the green building rating system for existing buildings by the Building Research Establishment of the United Kingdom and one of the few environmental certification programs to cover manufacturing and R&D facilities, etc., on which IIF focuses.
Data is obtained from nine elements, including "Water," "Energy," "Resilience," and "Health & Wellbeing" from an environmental and sustainability perspective, and the rating results are displayed in six levels (Outstanding, Excellent, Very Good, Good, Pass, Acceptable).

For more details on the certification program, please refer to the BREEAM website.

BELS certification is provided under a public evaluation system, which evaluates the energy conservation performance of non-residential buildings. In the BELS system, five levels of energy conservation performance are evaluated by a third party based on various criteria, irrespective of whether they are new buildings or existing buildings. BELS certification, which is the first public evaluation system specific to energy conservation performance in Japan, is expected to promote further improvements by providing appropriate information and promoting the energy conservation performance of buildings.

ResReal is the certification system that quantifies and visualizes the resilience of real estate against natural disasters. In addition to the four factors of "robustness (location and building)," "redundancy," "readiness," and "substitutability," the system also considers advanced initiatives such as the installation of rainwater harvesting tanks and collaboration with local communities, as well as stockpiling and disaster drills to ensure a comprehensive and quantitative evaluation.The certification assesses the resilience of real estate for each natural disaster,such as floods (external and internal flooding), earthquakes,tsunamis, storm surges, and landslides^*.

• *Only "flood" among the above natural disasters starts certifying from the end of January 2023.
