「The Company is also promoting ZEH adoption for newly built condominiums. In the fiscal year ended March 2025, 4 buildings were completed, and in the fiscal year ended March 2026, 3 buildings were completed.」

「また、マンション事業においてもZEH－M（ネット・ゼロ・エネルギー・ハウス・マンション）化を進めており、当連結会計年度においては3棟がZEH－Mとなりました。」

「We made home storage batteries a standard option in February 2025. We are also promoting the conversion of condominiums to ZEH-M, and 4 buildings became ZEH-M during the consolidated fiscal year.」

「Our continued efforts to standardize ZEH in 2016, the higher-performance ZEH+ (ZEH Plus) in 2019, and standards exceeding ZEH levels in 2022, ahead of other lightweight steel prefabricated housing manufacturers, and to advance measures toward the government's goal of a decarbonized society by 2050, led to the company's fourth consecutive Corporate Award for Special Excellence in Energy-Efficient Housing.」

「In the condominium business, THE CROSS CITY TOWER (Naniwa Ward, Osaka: 190 units) was completed in September during the second quarter. In August, we also began sales of Sun Maison Kori-en Station (Neyagawa, Osaka: 153 units), which had obtained ZEH-M Oriented certification.」

「In rental and welfare housing, we focused on promoting ZEH for rental multi-unit housing, and the ZEH ratio was 100% in the first quarter of the current consolidated fiscal year (90% in the same period of the previous year).」

「We also promoted ZEH adoption in condominiums and began construction of 2 ZEH-M Oriented properties.」

「In rental and welfare housing, we are promoting ZEH-M rental housing and focusing on proposals for nursing care and welfare facilities that reflect the needs of operators, residents and users from 3 perspectives, drawing on our expertise in designing and constructing various facilities. The ZEH ratio for rental and welfare housing during the consolidated cumulative third quarter, excluding garage houses that cannot be made ZEH-compliant, was 89%, compared with 81% in the same period of the previous year. In the Frontier business, Sanyo Architect Co., Ltd. handles the sale and construction of structural steel frames using our lightweight steel technology, as well as the sale of eco-energy equipment such as solar power systems and storage batteries. We are also focusing on sales of charging equipment for electric vehicles and other vehicles.」

The ZEH ratio for the first quarter of the current consolidated fiscal year was 90%.」

「As a measure toward a 100% ZEH ratio, we established third-party ownership schemes for solar power, including PPA (Power Purchase Agreement) arrangements. By reducing the upfront cost of installing solar power, we believe these schemes can provide a solution to budget overruns associated with recent price increases for customers seeking higher building performance.」

「For rental and welfare housing, the company also standardized ZEH specifications for rental apartment buildings from the current fiscal year, and adoption has progressed steadily. Since June, when contracts began, the company has achieved 100% ZEH compliance excluding garage houses, which cannot accommodate ZEH specifications.」

「As part of our environmental initiatives, we worked to increase the ZEH (net-zero energy house) ratio, which reached 92%, compared with 75% in the previous fiscal year. In rental and welfare housing, we are working to standardize and promote ZEH in rental multifamily housing, in addition to detached housing, as an initiative toward realizing a decarbonized society.」

「In response to the government's October 2020 declaration of carbon neutrality by 2050, we further promoted ZEH-compliant housing, achieving a ZEH ratio of 75% in FY2020.」

「We are also expanding sales through joint campaigns conducted by NISSAN MOTOR CO.,LTD., Mitsubishi Electric Corporation and us using V2H (vehicle-to-home) houses.」

「In the renovation and renewal distribution business (existing-home distribution), we are focusing not only on renovating homes, facilities and stores, but also on Eco & Safety initiatives such as seismic retrofitting, solar power generation, and sales of storage battery systems compatible with the post-FIT environment.」

「For detached houses during the first 9 months of the fiscal year, we began sales of “Suma e-Town Urban Community Kuwana South,” the first project in Japan to be selected under the low- and mid-rise condominium category of the Ministry of the Environment's ZEH-M (net-zero energy houses for multifamily housing) support program.」

「During the consolidated cumulative second quarter, in detached housing we promoted sales by advancing smart homes and low-CO2 homes, including "A Comfortable Life Connected by AI and IoT" using AI speakers and IoT technology, ZEH (net-zero energy houses), and LCCM (life-cycle carbon-minus) housing.」

「In FY2017, in addition to ZEH proposals, we brought to market "A New Way of Living with V2H" (Note 2), which stores electricity generated by solar power in an electric vehicle and supplies power from the vehicle's storage battery to the home during emergencies such as a power outage.」

「For detached homes, the company worked to create one-of-a-kind homes tailored to individual customer needs and develop new customer segments, including by launching “A Proposal for a Life of Enjoyment,” which enables a disaster-prevention shelter to be used as a multipurpose space, and “life style KURASI’TE: A Life Transformed by V2H,” which connects electric vehicles with daily life.」

「We sold a large-scale solar power generation facility.」

The ZEH share of orders reached 52%, achieving the government target 4 years ahead of schedule.」

「We held the Eco & Safety Housing Festival under the banner of a "Zero-Energy Declaration" and worked to secure orders for homes equipped with advanced energy-generation and energy-saving systems and high insulation performance.」

「① Development of self-sufficient homes using renewable energy, including storage batteries linked to solar power generation and solar thermal utilization ② Research into stable renewable energy sources, such as geothermal energy, as an alternative to intermittent solar power generation」
