Demonstration and Promotion of Environmentally and Disaster-Conscious Offices

「Under the Seventh Medium-Term Management Plan and the Environmental Action Plan “Endless Green Program 2026,” the Group has positioned ZEH and ZEB rates as key performance indicators (KPIs) for its products and is advancing related initiatives.」

「“Premist Miyazakidai RISETERRACE (Rise Terrace)” (Kanagawa Prefecture), launched for sale in July 2024, was the first condominium for sale developed by the Company to receive both ZEH-M Ready certification and certified low-carbon housing certification. Sales have progressed steadily, supported also by its location, which combines a natural environment with convenient access to daily necessities.」

「We set a target of ensuring that, by FY2030, 100% of all buildings newly provided by the Group meet ZEH or ZEB standards, in principle, and that all buildings are equipped with solar power generation systems. As a specific example, in October 2022 we launched “TORISIA,” a rental housing product that meets the ZEH-M Oriented standard as a standard specification. For condominiums for sale, we decided to adopt ZEH-M specifications, in principle, for all “Premist” properties commencing construction from FY2024 onward.」

「As part of our carbon-neutral strategy, we have actively made proposals concerning the conversion of buildings to ZEBs and the installation of solar power generation equipment.」

「By FY2030, in addition to reducing CO₂ emissions across the entire value chain by at least 40% from FY2015 levels, we aim to achieve a 100% ZEB and ZEH rate in Japan and contribute to the wider adoption of renewable energy by installing solar power generation systems, in principle, on the roofs of all newly constructed buildings.」

「By 2030, we aim to ensure that, in principle, all buildings newly provided by the Company meet ZEH or ZEB standards. We will also proceed with installing solar panels on all buildings.」

「In support services for offices, factories and other operating sites, we strengthened efforts to commercialise industrial parks developed by the Company and attract companies. We also held an online ZEB seminar to promote energy-efficient buildings as part of the transition to a decarbonised society.」

「The Company is promoting energy conservation and carbon reduction throughout the development by linking an “energy centre (natural gas cogeneration system)” with AI. Premist Tower Shin-Sapporo (Hokkaido), which incorporates panel heaters, heat-exchange ventilation equipment and other technologies, was selected by the Ministry of Economy, Trade and Industry for its ultra-high-rise ZEH-M demonstration project.」

「In the Tokyo metropolitan area, Premist Heiwadai (Tokyo) was selected by the Ministry of Economy, Trade and Industry for the ZEH-M Ready program, in recognition of its initiatives to supply solar-generated energy to each condominium unit and reduce carbon emissions.」

「In the Tokyo metropolitan area, Premist Heiwadai (Tokyo) was selected by the Ministry of Economy, Trade and Industry for the ZEH-M Ready program, in recognition of its initiatives to supply solar-generated energy to each condominium unit and reduce carbon emissions.」

「In the Chubu region, Premist Inagawa (Shizuoka Prefecture) was selected by the Agency for Natural Resources and Energy of the Ministry of Economy, Trade and Industry as Shizuoka Prefecture’s first high-rise ZEH-M demonstration project, in recognition of its provision of comfortable living spaces to customers and its environmental initiatives.」

「We are also accelerating these initiatives in our products, including by making all detached houses meet ZEH (net zero energy house) specifications from April this year.」

「In support services for offices, factories and other operating sites, we have strengthened proposals for companies establishing or relocating sites, proposals to convert offices and factories to ZEBs, and efforts to attract companies to industrial parks developed by the Company.」

「We began a demonstration project at Daiwa House Saga Building for an office that is self-sufficient in electricity generated from renewable energy. The building was selected by the Agency for Natural Resources and Energy of the Ministry of Economy, Trade and Industry for the FY2017 Net Zero Energy Building Demonstration Project. By introducing environmentally friendly technologies, including solar power generation (83.2kW), lithium-ion storage batteries (75kWh), and an air-conditioning system using well water and solar heat, it achieved a ZEB (net zero energy building) capable of operating independently without relying on electricity purchased from a utility company.」

「By combining “passive control,” which harnesses natural forces, “active control,” which generates, saves and stores energy, and “smart management,” which controls these systems appropriately, CO2 emissions can be reduced by up to 53% compared with the reference values under the revised 2013 energy conservation standards.」
