We would like to introduce a case where we utilized subsidies from the Child-Rearing Green Project to carry out insulation renovations using the insulation board "Replus Board." This is a wooden two-story house built 41 years ago in Sapporo City, Hokkaido. The first-floor flooring uses "Ractee" with a thickness of 105mm. The first-floor Japanese-style room and the second-floor Japanese-style room use "Replus Board" with an insulation thickness of 45mm for the walls and ceilings. Please refer to the related materials for the construction examples.

As a successor project to the Child-Rearing Green Business, subsidies for the construction of energy-efficient homes and support for energy-efficient home renovations have been announced. The Housing Energy Efficiency 2026 Campaign, a collaboration among three ministries, has strengthened support for housing energy efficiency with a supplementary budget of 378 billion yen for fiscal year 2025. Construction that begins on or after November 28, 2025, will be eligible, and a key change to note is that the condition for starting new construction is now based on the commencement of foundation work. The total budget for new construction and the subsidy amount per unit have also been reduced. In the Future Eco Housing 2026 project, which only targets renovations, eligible homes are limited to those that do not meet the energy efficiency standards set in 1999 prior to renovation. Please refer to the related materials summarizing the information available until December 17, 2025.

Due to the enforcement of the revised Building Standards Act in April 2025, the content of the building confirmation application documents has changed, leading to longer periods for building confirmation approvals due to deficiencies in the application documents. As a countermeasure, the provision of this support service has begun. Implementer: Japan Building Disaster Prevention Association (General Incorporated Foundation) Service Period: November 10, 2025 (Monday) to March 9, 2026 (Monday) Content: Utilizing AI to evaluate the presence or absence of certain required information in the building confirmation application documents related to the construction of two-story wooden single-family homes, etc. Usage Fee: Free (limited to a maximum of 5 times within the last 24 hours per account) For more details, please refer to the Press Release from the Housing Bureau of the Ministry of Land, Infrastructure, Transport and Tourism dated November 10, 2025.

As of April 2025, compliance with energy-saving standards for buildings has become mandatory. Accordingly, compliance with energy-saving standards will be added to the items for completion inspection. During the inspection, you may be asked to present shipping documents from the time of delivery to confirm the specifications and installation status of the insulation materials, so please keep them safe until the inspection is completed. For the insulation thickness and thermal resistance values corresponding to our company's insulation product model numbers, please refer to the attached product specification sheet.

Insulation renovation registered products for the Child-Rearing Green Housing Support Project We have added product installation points and case studies to the introduction page of the interior lining Replus board, which is installed from the inside. With an industry-leading thermal conductivity of 0.019 W/(m·K), it becomes easier to meet the subsidized m3 even with partial renovations. The insulation thickness is available in 30mm and 45mm options. We encourage you to take advantage of this opportunity to utilize subsidies and consider it alongside renovations of water areas and windows.
