Home Energy Conservation 2025 Campaign FAQ

Updated: July 2025, 8

I have compiled a list of frequently asked questions.

Please use this as a reference for your application.

Q. Do I need to register to apply?

Business registration is required for the Home Energy Saving Campaign.
First, please register an umbrella account (one account per business).

Q.What is a contact account?

The person who will actually make the application must be registered.
You cannot apply just by registering a central account.
Once you have registered your account and linked it to the parent account, you can submit your application.

We have compiled a video that shows you how to get an account, register, and link your account.

We act as an agent for applications for business registration (general account and person in charge account).

You can check the progress of your budget on the homepage.

※For those applying for Childcare Green Housing※
　Whenever possible, new homes should be built within one month of the completion of foundation work.
　For renovations of existing housing, we ask that you submit your application for subsidy within one month of completing the work.
(Applications for grant funding submitted long after the completion of each construction project may be given a lower priority.)

Q. Can subsidies be combined?

Subsidy systems of local governments can be used in conjunction with other systems, except for those funded by national funds.

For example ...
Advanced Window Renovation 2025 (national government) and Cool Net Tokyo* (local government)）
　　　　　*Project to promote the spread of insulated and solar-powered homes that are disaster-resistant and contribute to health

△ Advanced Window Renovation 2025 (National) and Insulation Renovation (National)
　　　Window renovations are applied for as an advanced window renovation, and floor insulation is applied for as an insulation renovation.

✖ Advanced window renovation (national) and insulation renovation (national)
　　　Apply for advanced window renovation and insulation renovation

　Please note that if the subsidy items overlap, they cannot be used together.

✖ Child-rearing green housing (national government) and ZEH subsidies (national government)　New construction
