Frequently Asked Questions


Who can participate in the Passivhaus Open Days? 

All building owners/building users of Passivhaus buildings or those renovated to the EnerPHit standard, which have been calculated with the Passivhaus Planning Package (PHPP) can participate. Projects can be at various stages - from fully occupied & certified to under construction and aiming for certification.


Do visitors have to register?

We encourage all visitors to register for tours. Booking details will be specific to each tour & run by tour organisers, NOT the Passivhaus Trust. The properties that are opened are often private homes. Registration provides us and the owner with a level of assurance that the process is being managed with care. Some tours may operate a walk-in tour - please check all tour details.

Host Attendee

Is there a participation fee?

No, registration and participation in the Passivhaus Open Days is free. (There are fees on Eventbrite to run free events, however alternative free platforms are available.)

Do I need to show a ticket to enter?

No, the host will have a list of names to confirm your registration.

Is there a limitation on attendee numbers?

No, however, we recommend a maximum of 10-15 attendees per host to safely guide large groups through a property. Participants must stay within the site of the host. 

When will the event address be sent to me?

To protect the privacy of some homeowners addresses are sent just before the event takes place at the discretion of tour hosts.

Which rooms in my building will visitors look at?

Those running the tours decide which rooms are shown to visitors and at what times. This will be dependent on several factors such as whether residents are in-situ etc.

Is there any insurance coverage for visitors?

No, there is no special insurance coverage. If something in the building/apartment is damaged, the visitor or, if applicable, their liability insurance is liable.

How do I market my tours?

The Trust will promote & support the event but further help its appreciated to attract new people & maximise exposure. You could share your viewing via: 

  • Social media

  • Through your website / Newsletter

  • Your local council newsletter

  • Your local area's environmental network/action groups


Can I run a site visit separate to the Open Days?

If you simply cannot make your tour dates align with the open days, yes, you can run a solo site visit. But, it will miss the branding of the Passivhaus Open Days, and inclusion in an international cohesive event run by a global joint community.
