[ZEB] Apartment complex/Subsidy
Updated: July 2026, 1
The Ministry of the Environment has announced its budget for fiscal year 7.Click here for details
A zero energy building (hereinafter referred to as ZEB) refers to a building whose energy consumption is reduced to zero through energy conservation and the use of renewable energy.
ZEB is a subsidy that can be used to introduce energy-saving, high-performance building materials and equipment to existing, newly built, expanded, and renovated buildings.
Since it is difficult to get as close to zero as the definition of ZEB, ZEB also has systems called Almost ZEB and ZEB Ready.
The subsidy rate is 2/3 of the eligible expenses and the upper limit is 500 million yen, which is a high subsidy rate and amount that is attractive, but the hurdles to apply are high and the preparation period is long.

For manufacturers considering ZEB
The Japanese government states that the ideal state of housing and buildings in 2030 is to ensure that newly constructed housing and buildings have energy-saving performance at the level of ZEH and ZEB standards, and that 6% of newly built single-family homes have ``Solar power generation equipment must be installed,'' ``Energy saving standards must be raised to ZEB standard energy saving performance and compliance must be made obligatory by 2030 at the latest.'' As part of this intensive period for strengthening countermeasures, all policies will be mobilized to accelerate efforts.
In order to speed up this promotion, there are preferential treatment measures such as a subsidy system for those who are currently aiming to become ZEB.
At least 40 application forms are required to apply for ZEB, which is a heavy burden for people who are busy with new construction or renovations, so we provide consulting in collaboration with engineers with specialized knowledge. We support optimal ZEB conversion.

Trouble that may occur when applying for ZEB subsidy
Currently, buildings that fall under ZEB can receive subsidies from the government.
However, there are many documents required for application, and the recruitment period is very tight.
Therefore, there are many problems such as the following.
○The recruitment period was very tight and I was preparing the attached documents.The application deadline has passed!
○Even though I needed to prepare a seal certificate,I wasn't prepared!
○Documents were not made known to business operators,I couldn't apply in time!
○Although I had to apply for construction completion,そのThe deadline has passed,I couldn't receive the subsidy!
etc.

ZEB judgment criteria
ZEB | Buildings with net zero or negative annual primary energy consumption |
Nearly ZEB | A building that satisfies the requirements of ZEBReady as a building that is as close to ZEB as possible, and that uses renewable energy to bring annual primary energy consumption close to zero. |
ZEB Ready | As an advanced building with ZEB in mind, it is equipped with highly insulated outer skin and highly efficient energy-saving equipment. |
| Name | Reduction rate from standard value | Form of energy creation | Method of calculation | |
Excluding energy creation | Including energy creation | |||
| ZEB | 50% or more and | 100% or more | In addition to self-consumption, charging also applies. (Installation location is on the premises) | Evaluated at the time of design, excluding "other loads," using calculations based on the "Ministerial Ordinance Establishing Building Energy Consumption Performance Judgment Standards" (Ministry of Economy, Trade and Industry/Ministry of Land, Infrastructure, Transport and Tourism Ordinance No. 1 of 2016) or an equivalent method. |
| Nearly ZEB | 75-less than 100% | |||
| ZEB Ready | 50-less than 75% | |||

Regarding the cost of ZEB conversion
Implementing ZEB conversion may increase the initial cost, but since subsidies can be used to cover construction and equipment costs associated with ZEB conversion, and the running cost reduction effect is also improved, implementing ZEB conversion has a greater cost advantage. There are also cases.
Below are examples of cost benefits obtained by converting existing buildings to ZEB.
The investment recovery period required for ZEB has been kept to around 10 years.

Condominiums cannot apply because they are not eligible for subsidy.
If the certified copy of the building register shows that the building is for civilian use, such as an "office," then the application can be made by treating it the same as a new building and making the calculations.
