Help Regensburg with Heat Planning
If you consent, only the data technically required for the building data donation and heat planning will be transmitted to the city administration. This includes, in particular, the full building address, building coordinates, building ID, and the approved input and calculation results. Because the data relates to a specific building, it is not anonymous. Registration or the provision of names and contact details is not required. Submission is linked to downloading the PDF report and takes place when you request the report. The report also contains a randomly generated deletion link that lets you delete the submitted data after a confirmation dialog.
