住宅省エネ2026｜工事写真撮影アプリ

This app is for taking construction photos for each project in the 2026 Housing Energy Saving Campaign.

To use this app, you will need a separate account for this app, in addition to your Housing Energy Saving Portal account.

To use this app, you must log in to the Housing Energy Saving Portal's administrator account and register your usage through the common portal.

(Simply downloading the app will not allow you to use it.)



- Photos taken with this app are saved on the server, retaining the image, location information, and shooting date and time as they were taken.

- Photos are organized into folders by shooting date and location.

- Photos saved on the server can be shared with third parties by sharing the URL of the storage location.

- Shared recipients can view this information using a web browser; no special apps are required.

- Sharing can also be done on a folder-by-folder basis.




- Photos taken with this app can be assigned "previous/next tags."

- If you want to manage multiple photos of the same subject taken on different days, linked chronologically, register the same "previous/next tags."

* When you take a "Post-Construction Photo" from the details screen of the photo you want to link, the same "before and after" tags will be automatically registered to the photo you took.

* Anyone who receives either of the before and after photos can view all of them.


* You can assign "parent and child tags" to photos taken with this app.
* If you want to manage accessories or close-ups of parts of the subject as child photos, register the parent photo's file ID as the child photo's "parent and child tag."
* When you take a "child photo" from the details screen of the photo you want to link, the parent's file ID will be automatically registered as the "parent and child tag" of the photo you took.
* Anyone who receives either of the parent and child photos can view all of them. (Including child photos where the child photo is the parent photo)


* For each project of the Housing Energy Saving 2025 Campaign, construction photos are submitted either by uploading images or by entering the URL of this app.

* When submitting via URL, you can choose to submit by photo or by folder.


* Ownership of photos taken with this app belongs to the secretariat.
* Photos taken with this app are automatically deleted from your device and cannot be copied.
* Photos taken with this app will be deleted if they are deemed irrelevant to the application for this campaign.
