2012 Passive House Days reviews

Czech Republic


The Czech Passive House Association Centrum Pasivníhu Domu welcomed over 700 visitors in 48 houses. "We noticed that people are getting more informed", says Jana Stará, organiser of the event. "They come with practical questions or even own projects to consult. Our visitors were mostly people who already live in passive/energy efficient house, are just building one or plan to do so in near future."


The three day event included guided tours with architects, theoretical seminars as well as practical illustrations of Passive House technologies and materials.



Hungary's Passive House Days event turned out to be more successful than ever with several media coverages in the mainstream media and hundreds of visitors. "Our bus tours were completely booked up," says László Szekér, director of iPHA's Hungarian Affiliate PAOSZ. "Next year we decided to offer several bus tours, because one was not enough."




The Irish Passive House Days were put on by iPHA's Affiliate, the Passive House Association of Ireland (PHAI). There were six official open houses, covering a broad geographical spread of the country.  Some participants opened for one day, others for all 3 days.

Reports indicate that there was a high level of interest with most hosts entertaining between 10 and 20 visitors. Many of the visitors were prospective self-builders who were interested in learning more about Passive House principles, and in some cases the specifics of certain aspects of the project e.g. heat recovery ventilation, windows etc.  Other visitors to the open houses included a mixture of architects, engineers and students.




Italy's various Passive House Days event included a guided tour through a 7 floor residential Passive House refurbishment project in Chiasso, located near the Swiss-Italian boarder. The event, organised by iPHA's PassREg partner eERG-PoliMI, attacted 30 designers, architects, engineers as well as building owners from Northern Italy and Ticino in  Switzerland. The building is to be certified as a Passive House; a photovoltaic installation on the roof and façade will cover the remaining energy demand.




The Slovak Passive House Days, put on by iPHA's Affiliate iEPD, involved 23 houses (mostly residential) and 3 architectural studios. More than 650 visitors came to experience the comfort Passive Houses offer, speak to residents about their experiences and ask architects and designers about the components and methods used in making these buildings Passive Houses.




Three Spanish Passive Houses opened their doors for the very first time this year, welcoming a total of 100 visitors. The Spanish Passive House Association Plataforma PEP was pleased to see not only construction experts and technophiles but also many visitors without any technical background interested in finding out what Passive House is all about and curious to learn how these buildings stay warm without heating and how the heat recovery ventilation works.     




The Swedish Passive House Days were put on by iPHA's Swedish Affiliate, IG Passivhus Sverige. 120 visitors came to see the currently four internationally Certified Passive House buildings, including two kindergardens, a single-family house and a tennis hall.

Here are some of the comments from visitors: 


United States


The Mamaroneck Passive House in New York was open to the public all day Saturday 10 and Sunday 11 November and had an incredible turn out. Close to 200 people diverted from their week- end routine to come and visit the construction site and see the finished skeleton of the house only waiting for siding outside and for blown in cellulose and Sheetrock inside.


Contractors, engineers, realtors, students, manufacturers, the French American School Board and plenty of homeowners and neighbors flocked to the house with the new hope of finding some reasonable solutions to both Sandy's shake ups on top of a day to day healthier lifestyle. Read more
