DAIKYO Promotes Standardization of GX ZEH Specifications for Highly Efficient Housing with

TOKYO, Japan – January 27, 2026 – DAIKYO INCORPORATED (“DAIKYO”) announced today that it has decided to adopt “GX ZEH (Green Transformation Net Zero Energy House )”—a new energy-saving housing standard with thermal insulation and energy-saving performance above the ZEH standard—as standard^*1 for the condominium brand THE LIONS.

GX ZEH is an energy-saving standard with performance at a higher level than the existing ZEH standard. With a significantly higher thermal insulation performance of the building envelope compared to the existing standard and the adoption of high-efficiency facility systems, it achieves significant energy conservation while maintaining a comfortable indoor environment. Furthermore, solar power generation facilities and other renewable energy are used to seek net zero annual primary energy consumption.
Coming into effect from April 2027, the GX ZEH standard is a new environmental indicator that will be at the center of the decarbonization policies stipulated by the Ministry of Economy, Trade and Industry toward achieving carbon neutrality by 2050. Ahead of the standard’s application, DAIKYO is adopting the GX ZEH standard in new condominiums that will be developed in the future. The first property to implement this newly decided policy is “The Lions Miyagaoka 2-Chome” (tentative name) currently being developed in Hokkaido.
So far, DAIKYO has formulated a policy of adopting the ZEH standard as its standard specifications in 2021—ahead of the industry—to achieve both improved environmental performance and a comfortable living environment, and the company has promoted the development of condominiums with ZEH specifications. It will continue to contribute toward reducing the burden on the environment through creating advanced and safe housing that has both energy-saving performance and living comfort.
DAIKYO will continue to create homes that further enrich the lifestyles of customers through THE LIONS brand.

■Key Features of the GX ZEH Standard
1. Thermal insulation performance
The performance grade of thermal insulation and such in the housing performance labeling system has been raised from Grade 5—the existing grade for ZEH standard—to Grade 6. This enhances the building envelope performance to reduce heat loss, significantly improving the thermal environment of living spaces. As a result, the energy efficiency of air conditioning is improved, allowing both comfort and energy-saving performance to be achieved.

2. Energy-saving performance
The primary energy consumption grade in the housing performance labeling system has been raised from Grade 6—the existing grade for ZEH standard—to Grade 8, increasing the primary energy consumption reduction rate from 20% to at least 35%. This is expected to significantly reduce utility costs as well as contribute toward decarbonization through reducing CO₂ emissions.

■ZEH-M projects by DAIKYO and ANABUKI CONSTRUCTION
DAIKYO INCORPORATED and ANABUKI CONSTRUCTION INC.—which undertake housing development in the real estate business of ORIX Group—have built a total of 83 condominium projects with ZEH-M specifications (on a completion basis, as of the end of December 2025).
In July 2018, DAIKYO achieved a primary energy consumption reduction of at least 75% at Lions Ashiya Grandfort and received Japan’s first BELS evaluation certification for Nearly ZEH-M^*3. Currently, it is promoting the development of condominiums with specifications that fulfill the ZEH-M Oriented standard.
Furthermore, The Lions Setagaya Hachimanyama—Japan’s first^*4 condominium meeting the top ZEH category of ZEH-M with all units also fulfilling the ZEH standard—was completed^*5 in September 2025.
DAIKYO will continue to actively carry out condominium development aimed at achieving both environmental consideration and higher quality of residential living.
