Sanken Launches 'Standard-ZERO': A New Home That Eliminates Electricity and Gasoline Bills by Integrating High-Performance Housing, Solar Power, and V2H/EV Technology – Next-Generation Model House to Be Unveiled in Collaboration with Authorized Dealers

Sanken Co., Ltd. (Headquarters: Kakogawa City, Hyogo Prefecture; President: Hiroaki Nakazawa; https://www.e-sanken.co.jp) announces the launch of a new product, 'Standard-ZERO,' which proposes a lifestyle independent from electricity and gasoline bills by combining homes with world-class insulation performance, renewable energy, and electric vehicles (EVs).

This product is a next-generation home designed to achieve a life 'without buying electricity or gasoline' by integrating an 8kW solar power generation system into a HEAT20 G3-level high-performance home and utilizing electric vehicles (EVs) as household energy equipment. A model house allowing visitors to experience this product will be unveiled in summer 2026, with exhibition plans underway in collaboration with Hankan Sanyo Holdings Group, which operates authorized BYD dealers.

■ Social Context | From 'Housing Performance' to 'Living Infrastructure'

In recent years, the role expected of homes has significantly evolved due to intensifying natural disasters and rising energy prices. While homes have traditionally emphasized residential performance such as 'insulation' and 'comfort,' today's priorities include:

- Security to maintain daily life during power outages

- Energy design resilient to electricity and fuel price fluctuations

The perspective of treating homes as living infrastructure is now crucial. The ability to generate emergency power at home during disasters also helps avoid harsh evacuation center conditions, reducing stress by allowing residents to stay in their familiar homes. Against this backdrop, there is growing demand for integrated design of housing, energy, and mobility as a unified system.

■ Concept

'A Life Without Buying Electricity or Gasoline'

Based on the philosophy of Sanken’s housing standard '2050 STANDARD HOUSE,' we propose a new way of living that integrates high-performance homes, solar power generation, and electric vehicles (EVs). By using electricity generated at home for household needs and charging EVs, we realize a circular energy lifestyle encompassing both home and vehicle. As homes become energy hubs connecting power generation, storage, and mobility, we present an unprecedented residential model.

■ Key Features of Standard-ZERO

① World-Class Insulation (G3) for Ultimate Energy Efficiency

Sanken homes adopt a full external insulation method, achieving high insulation and airtightness at the HEAT20 G3 level.

Compared to standard homes (Insulation Grade 2), heating costs in winter are drastically reduced. High-performance homes can reduce electricity bills to approximately one-fourth of conventional homes, minimizing overall household energy consumption.

② 8kW Solar Power for Energy Self-Sufficiency

An 8kW solar power system installed on the roof enables households to generate their own electricity.

Combined with battery storage and V2H (Vehicle-to-Home) systems, this enables energy self-sufficiency during nighttime, rainy days, and power outages, creating a circular energy lifestyle.

③ EVs as Household Energy Equipment

With Standard-ZERO, electric vehicles (EVs) are not just transportation but are used as household energy equipment. By charging EVs with electricity generated from solar power, there is no need to purchase gasoline.

The model house will feature the latest EVs in collaboration with Hankan Sanyo Holdings Group, the authorized BYD dealer in Hyogo Prefecture. For a typical kei car requiring about ¥10,000 per month in gasoline, this could save approximately ¥120,000 annually and ¥3.6 million over 30 years.

④ Using EVs as 'Mobile Batteries'

Electric vehicles (EVs) can supply power to homes via V2H systems.

During power outages, EVs can power lighting, heating and cooling, and communication devices, making homes resilient and capable of sustaining life during disasters.

■ Significant Reduction in Lifecycle Costs

Standard-ZERO prioritizes lifecycle cost reduction over initial investment. Compared to standard homes, it significantly reduces energy costs such as electricity and gasoline, potentially creating a cost difference of over ¥10 million over 35 years. This makes it a valuable 'inflation-resistant home' that minimizes impact on household budgets even amid rising energy prices.

■ Model House Information

Sanken plans to unveil a model house in summer 2026 where visitors can experience the 'Standard-ZERO' lifestyle. In collaboration with Hankan Sanyo Holdings Group, which operates authorized BYD dealers and European import car dealerships, the exhibition will integrate housing, energy, and mobility, offering a tangible experience of next-generation living.

■ Future Developments

Sanken will continue to propose new living environments that integrate high-performance homes, renewable energy, and electric mobility, advancing housing solutions toward a 2050 carbon-neutral society.
