Regarding your energy performance certificate, no specific input from Vaanster is required. Your advisor can indicate that the central installations are inaccessible and mark the status as "unknown" in the assessment.

Why is the space inaccessible?

The reason for limited access stems from the unique ownership structure. While technical spaces are typically accessible when owned by the building owner, Vaanster's installations are legally distinct. These systems are owned by Vaanster through a specific legal right of superficies, which means they are not considered part of the building's standard infrastructure. Consequently, the energy performance advisor will document the reason for restricted access in the project file.
