What would you like to add?
📖 Record an event
What happened to the building? Renovation, maintenance, system replacement — with date and scope.
The event becomes part of the building history and survives a change of ownership.
🔐 Who has access
Every access you granted, what it was granted for and how long it lasts. Revoking takes effect immediately; the data itself stays untouched.
No access granted yet.
New access codes are issued by your energy consultant — that keeps a stolen PIN from creating access.
📥 Incoming reports
What tenants, agents or your property manager have reported. Accepting turns a report into a task for your energy consultant; it does not change the passport by itself.
No open reports.
🏠 Photo of the house
Upload a photo of your house. It appears on the passport card once your energy consultant has approved it (four-eyes principle).
