The 住宅省エネ2025工事写真撮影アプリ is designed specifically for capturing construction photos related to the Housing Energy Efficiency 2025 campaign. This application requires a unique account separate from the Housing Energy Efficiency Portal, which must be obtained through an application process. Users can store images with their associated location data and timestamps on a server, with the ability to organize photos into folders based on the date and location of capture. Furthermore, photos can be easily shared with third parties through a URL, eliminating the need for special applications.

This app also provides advanced photo management features such as 'before and after' tags for chronological tracking of photos taken on different days, and 'parent-child' tags for grouping related images. Users can submit their construction photos either by uploading images or by entering a URL, offering flexibility in submission methods. However, it is important to note that ownership of the photos belongs to the administrative office, and images are automatically deleted from the device and server after the campaign ends.
