Passive House Open Days 2026
Event details
Dates: 26 – 28 June 2026
Submissions close: 29 May 2026
What is it?
The Passive House Open Days is an event organised globally by the International Passive House Association, where owners open their homes and offices to the public to experience first-hand what a Passive House building feels like and to learn more information about building to the Passive House standard.
From 26 – 28 June 2026, Passive House homeowners and businesses invite the public to experience Passive House buildings, both residential and non-residential, for themselves, to enjoy the comfortable interior temperatures, view the ventilations system, ask questions and consider the range of possibilities of Passive House for your own building projects.
Why participate in this?
This is an excellent opportunity to share your journey to design and build a world class home or office, promote this way of building and what you have loved about the process and living in a Passive House.
Designers, builders, consultants, trades persons and suppliers involved in the project may be onsite to share their knowledge and experience about ultra comfortable, healthy and energy efficient buildings and answer any questions about the project.
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.
Have you participated in previous Passive House Open Days and your project is not on the map? You can contact PHI directly at info@passivehouse-international.org to have your past project added.
- To participate in the Passive House Open Days 2026, please register your project with us by completing the registration form.
You can submit a live, in-person tour or event or offer online tours, Q&A sessions or webinars. Projects can be at various stages – from fully occupied to under construction. Registration is free of charge .

Martins Farmhouse
Passive House Classic
This award-winning home was completed in 2023 and was New Zealand’s second Passive House to be constructed using strawbales. It also makes use of the light earth method and natural clay plasters serve as the airtight layer. The combination of natural materials and rigorous building science produced a deeply welcoming home that is warm, quiet and peaceful. The brief called for a home nestled in its rural landscape, highly durable and modest in size. Martins Farmhouse is an excellent example of biophilic design: a building which is integrated into the natural world and which is experienced with all the human senses. The owner is a Passive House communicator and advocate who has written and edited many publications in this field. Building industry professionals—engineers, builders, designers, quantity surveyors etc—who are interested in exploring the benefits of the Passive House standard are especially welcomed.
