Received the 2024 Minister of the Environment’s Award for Climate Action in the Advanced Adopter and Leading Applications Division (Mitigation category)

The GREEN renovation initiative for the Sustaina Branche Hongyotoku, a rental condominium project was awarded the 2024 Minister of the Environment’s Award for Climate Action in the Advanced Adopter and Leading Applications Division (Mitigation category).
Sustaina Branche Hongyotoku is the first property in Japan that has been completely renovated and converted from company housing to a rental condominium that achieves net-zero CO2 emissions when the building is in use. The project aimed to increase the value of existing condominiums and create new housing value. Under the “GREEN renovation,” a complete electrical renovation was undertaken, and Non-Fossil Certificates (with renewable energy designation) were introduced. In addition, features to enable the property to use non-fossil energy were incorporated, such as the installation of solar power generation equipment on the property’s roof, external walls, and balcony railings, the use of pure hydrogen fuel cells, and a centralized Eco-Cute water heater powered by excess power. Furthermore, the project received BELS certification as a result of achieving the heat transmission coefficient of the building envelope(UA value) and primary energy consumption corresponding to ZEH-M Oriented specifications.
Some units in the project were set aside as RESIDENCE LAB experimental residential housing for use in research and development that contributes to decarbonization and extending the longevity of buildings.
