Scroll right down to see participating locations and times

The International Passive House Open Days are an excellent opportunity to learn about Passive House and energy-efficient buildings.

Learn first-hand what it is like to live in a Passive House and what the building or retrofitting process was like. Enjoy the comfortable interior temperatures, take a look at the ventilation system, ask questions and consider the possibilities of Passive House for your own building projects.

Some participating locations will have professionals on hand with the knowledge and tools to explain the technical details of Passive House projects.

Passive House Owners

The Open Days really come alive if there are many participating projects to view. Only through the generosity of current Passive House owners can others experience the benefits of Passive House first-hand. PHINZ understands the effort this can take and fully appreciates those willing to spread the word through the most motivating avenue of all: hands-on personal experience.

Projects can be at any stage – from under construction to fully occupied. Registration is free of charge.

When you participate in the International Passive House Open Days 2022, you can add your project to the International PHI world map.

Have you participated in previous Passive House Open Days and your project is not on the map? You can contact PHI directly at to have your past project added.

Clad in steel on the south side and dark timber cladding on the north. The living room and balcony cantilever out above the garage with views down the stream to the Pauatahanui inlet.
