Technology Development Centered on “ECO & SAFETY”

「The ZEH (net zero energy house) ratio for detached homes for the current fiscal year was 94%, compared with 95% in the same period of the previous year. We will continue to target 100%.」

「当年度の戸建住宅におけるZEH（ネット・ゼロ・エネルギー・ハウス）比率については94%（前年同期95%）となりました。引き続き100%を目指してまいります。」

「The ZEH ratio, an area of continued focus, reached 93% during the interim consolidated accounting period, compared with 96% in the same period of the previous fiscal year.」

「At the “House of the Year in Energy 2024,” our detached-house product “life style KURASI'TE: LCCM Housing Level Model” received both the “Special Excellence Award” and the corporate “Special Award for Excellence in Energy-Efficient Housing,” marking our 10th consecutive year receiving an award.」

「For detached houses, we are focusing on proposals such as “W-eco design,” which combines environmental considerations with economic rationality to realize our business concept of “Eco & Safety (environment, safety and security),” and the disaster-resilient hybrid construction method of lightweight steel frames with reinforced-concrete construction on the first floor. The ZEH ratio, an area of continued focus, reached 96% during the interim consolidated accounting period, compared with 100% in the same period of the previous fiscal year.」

「The ZEH ratio for detached houses was 97% for the fiscal year, compared with 100% in the same period of the previous fiscal year. We will continue to target 100%.」

「The ZEH ratio for detached houses was 99% for the first 9 months of the fiscal year, compared with 100% in the same period of the previous fiscal year.」

「From FY2016, we launched homes with a UA value of 0.5 (model plan), a higher performance level than the ZEH-standard UA value of 0.6 in our sales areas. From FY2022, we further raised the UA value standard to 0.46 and sell these as high-spec, highly insulated homes despite their steel-frame construction. Following the government's October 2020 declaration of carbon neutrality by 2050, we further promoted ZEH-compliant homes, achieving a 100% ZEH ratio for newly built detached houses in FY2022.」

「Against this backdrop, our group continued working to sell homes exceeding the government-defined ZEH level as standard. Our proposal for “Renewal Cycle Carbon Minus Homes,” which applies LCCM (life-cycle carbon minus) homes designed for new construction to the existing-home sector, was selected for the first round of the Ministry of Land, Infrastructure, Transport and Tourism's FY2022 Leading Projects for Sustainable Buildings and Other Structures (CO2 Reduction Leadership Type). The ZEH ratio for detached houses was 100% during the first 9 months of the fiscal year, compared with 92% in the same period of the previous fiscal year.」

「The ZEH ratio was 100% for the first 6 months of the fiscal year, compared with 93% in the same period of the previous fiscal year.」

「As a further initiative as an Eco-First certified company, we have made performance standards exceeding the ZEH level our standard specifications for detached houses from April. The ZEH ratio for detached houses reached 100% during the first quarter of the fiscal year, compared with 92% in the previous fiscal year.」

「The ZEH ratio for detached houses reached 93%. The company will continue working to raise the ratio and will standardize specifications exceeding the ZEH level from April 2022.」

「The ZEH ratio for detached houses was 92% for the first 9 months of the fiscal year, compared with 85% in the previous fiscal year.」

「The ZEH ratio for detached houses was 93% for the first 6 months of the fiscal year, compared with 75% in the previous fiscal year.」

「For detached houses, on 27 April 2021 we launched “life style KURASI'TE New Healthy Home: Genki Ippai no Kurashi,” designed with consideration for air quality, thermal comfort and spatial comfort so that customers can enjoy a healthy and comfortable life over the long term. While working to propose new lifestyles that reduce health risks, we also sought to increase the ZEH ratio as an environmental initiative, raising it to 92% from 75% in the previous fiscal year.」

「Against the backdrop of the national policy goal of achieving average ZEH performance for newly built homes by 2030, we launched homes on the market from FY2016 with a UA value of 0.5 (model plan), a higher performance level than the ZEH-standard UA value of 0.6 in our sales areas. We sell these as high-spec, highly insulated homes despite their steel-frame construction. Following the government's October 2020 declaration of carbon neutrality by 2050, we further promoted homes compliant with ZEH, achieving a ZEH ratio of 75% in FY2020.」

「To help realize the government’s proposed “Society5.0,” we will seek to increase earnings by proposing “Eco & Safety” lifestyles to customers through services supporting smart lifestyles using AI and IoT, promoting sales of products meeting ZEH standards, expanding our nursery-school business and pursuing regional revitalization initiatives.」

「Against this backdrop, based on its business concept of “Eco & Safety,” the Group is promoting sales through the introduction of new products that contribute to preserving the global environment and ensuring people’s safety and peace of mind.」

「As a result, we received the “Excellence Award” at the “House of the Year in Energy 2018,” organized by the Japan Center for Area Development Research, a general incorporated foundation, which recognizes outstanding energy-efficient homes. This marked our fourth consecutive year receiving an award, including the “Special Excellence Award.” We also received the “Excellence in Corporate Performance Award” for the second consecutive year.」

「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.」

「For detached houses during the first 6 months of the fiscal year, we worked to promote sales by advancing smart homes and low-CO2 homes, including “comfortable living connected by AI and IoT” using AI speakers and IoT technology, ZEH (net-zero energy houses) and LCCM (life-cycle carbon minus) homes. In addition, “Kokochi shAir,” a system that sends air adjusted to a comfortable temperature in the living room and other areas to an air-conditioner-free dressing room or washroom, received the 12th Kids Design Award.」

「To help realize the government's “Society5.0,” we aim to increase earnings by proposing “ECO＆SAFETY” lifestyles through services supporting smart living using AI and IoT, promotion of sales of products compliant with standard ZEH, expansion of our childcare-center business and initiatives for regional revitalization.」

「For detached houses, based on our management principles of “creating comfortable spaces” and “proposing an engaging life,” we expanded proposals for lifestyles incorporating homes equipped with V2H (Vehicle to Home), which enables power supply from an electric vehicle, as part of standard ZEH compliance, as well as shelters that can be used for disaster preparedness during natural disasters and as multipurpose spaces under normal conditions. In addition, our ZEH-standard detached-house product, “life style KURASI’TE (2016 model),” received high recognition from a third-party organization. At the “House of the Year in Energy 2017,” it was the only steel-frame housing manufacturer (※) to receive the “Special Excellence Award,” achieving double honors together with the “Excellence in Corporate Performance Award.”」

「In line with the government's goal of making more than half of newly built homes ZEH by 2020, we made the “life style KURASI’TE” series compliant with ZEH standards. The ZEH ratio of custom-built homes, based on orders received during the year, reached 52%, achieving the government target 4 years ahead of schedule.」

「During the third quarter, we proposed housing based on the needs of residents, including the “Two Households, Three Generations Living Together: Let’s Live Together! Rebuilding Plan” campaign for people considering living with their parents, children or grandchildren, and the “Eco & Safety Housing Festival,” where visitors could experience homes designed for energy generation, energy conservation, safety and security. Each event was held in 4 areas: Tokyo, Aichi, Osaka and Fukuoka.」

「In addition to our conventional sales method centered on housing exhibition centers, we used cost-effective advertising that took customer attributes, such as demographic trends and family composition, into account. We also held the “Eco & Safety Campaign” from July through August as an event useful for housing and daily life, and actively proposed homes designed with consideration for the environment and durability.」

「Our detached-house product, “life style KURASI’TE,” was substantially upgraded in terms of its core performance, including insulation performance, and made compliant with ZEH standards. We also held the “Eco & Safety Housing Festival,” under the banner “Zero-Energy Declaration,” in Tokyo (July), Nagoya, Osaka and Fukuoka, and worked to secure orders for homes equipped with advanced energy-generation and energy-saving systems and high insulation performance.」

「We will continue advancing technology development under “ECO ＆ SAFETY.” In addition to energy generation, storage and conservation as eco-technologies, we will promote new initiatives using passive eco-design to realize comfortable lifestyles. Going forward, we will make zero-energy houses (ZEH) promoted by the government the standard.」
