[ZEB] Accelerated decarbonization renovation project for commercial buildings
Updated: July 2026, 8
In order to reduce CO2 emissions, many existing buildings do not meet current energy-saving standards, so it is essential to promote the decarbonization of these buildings.
In order to achieve ZEB, a decision has been made to accelerate support for the introduction of high-insulation exterior buildings and highly efficient air conditioning equipment.
Subsidies will be provided for the equipment and construction costs associated with improving the insulation of the exterior (insulated windows and insulation materials) and renovating high-efficiency equipment (air conditioning, lighting, hot water).
Construction plans for up to four years from fiscal year 2024 will also be covered.
This allows for a long construction period and allows for flexible construction planning.

Do you have this problem?
The application guidelines are complex, and it's time-consuming to check whether your equipment is eligible. It's a pain to check each and every insulated window and high-efficiency air conditioning unit you want to install to ensure they meet the strict standards.
I'm too busy with my main job to have time for the procedures. We cannot allocate resources to the complex paperwork and schedule management specific to grant applications.
The required documents are numerous, and I'm worried about being rejected due to incomplete documentation. This subsidy program has strict rules, and even minor deficiencies or omissions in the application documents can result in rejection, leading many to feel anxious about preparing the necessary paperwork.
