　More Comfortable and Environmentally Friendly Homes for Local Lifestyles

In recent years, the performance required of homes has changed significantly due to factors such as scorching summers and cold winters. In addition, with rising prices and energy costs, more households are becoming conscious of their utility bill burden in daily life.

Sayama Fudosan has reviewed the specifications of its housing brand "SAN+" with the aim of further promoting environmental considerations through local housing and providing high-performance homes where people can live comfortably even in climates with large temperature differences.

Furthermore, based on customer feedback such as "I want to live more comfortably," "I want to reduce household chores," and "I want to spend time in an open space," we have strengthened not only insulation performance but also equipment specifications that lead to easier daily living. We aim to improve customer satisfaction from both performance and comfort aspects.

In SAN+ home building, Sayama Fudosan, which handles land and subdivided land proposals, and its affiliated company Apple Home Co., Ltd., which handles design and construction, collaborate as the SAYAMA Group to promote community-based home building.

　Main Features of the New Specifications

1. Upgraded to High-Insulation Specifications Aiming for HEAT20 G2 Standard

The new specifications further enhance insulation performance from the conventional ZEH standard, evolving into a high-insulation home aiming for the HEAT20 G2 standard.
By improving the overall insulation performance of the home, it contributes to creating an indoor environment less affected by outside temperatures, and energy savings due to improved heating and cooling efficiency can also be expected.

As a trial calculation, the UA value is 0.44. The annual primary energy consumption is 54.4 GJ/year, a 31% reduction compared to the 2016 energy-saving standard, with an annual utility cost difference of 113,450 yen, and an estimated utility cost reduction of approximately 5.47 million yen over 35 years.

*The above figures are trial calculations by LIXIL Energy-Saving Housing Simulation. (Calculation date: 2025/11/19)

Comparison target: Equivalent to H28 energy-saving standard (Grade 4 assumed)

Calculation conditions: Region 6 (Saitama Prefecture) / Assumed total floor area 99.4m2, 4 people / Cooling 27℃, Heating 20℃ / No solar power, no HEMS (0 electricity sales)

Note: Conditions such as unit price and ventilation (Type 3) are based on the document. Values may vary depending on architectural values, plans, lifestyle, etc., and are estimates, not guarantees.

2. Expanded Standard Equipment to Enhance Livability

In addition to performance, the new specifications also enhance equipment directly related to daily life as standard.

• Dishwasher: Contributes to reducing household chores and saving time for busy dual-income and child-rearing households.

• High Studs (Ceiling height 2.7m): Creates a sense of vertical spaciousness, producing an open living space.

• High Sashes (2.4m): Designed to enhance natural light and a sense of openness, bringing brightness and spaciousness to the interior.

• Electric Shutters: Smooth daily opening and closing, considering security and comfort.

• Fami-Lock: Makes front door locking/unlocking convenient, allowing for smarter family entry and exit.

　Limited-Time Campaign to Support the Step Towards GX-Oriented Homes

In conjunction with the launch of the new specifications, a campaign will be held from April 1, 2026 (Wednesday) to June 30, 2026 (Tuesday), offering a 10% discount on eligible optional costs for GX-oriented homes. This offer is limited to the first 20 applicants.

While interest in high-performance homes is increasing, the cost of adding equipment can sometimes be a barrier to consideration. This campaign provides an opportunity to more easily consider home building that includes higher energy-saving performance and energy-creation equipment.
