Passive house

The seminar building of Centre Veronica Hostětín is the first public passive house in the Czech Republic

It uses modern technologies together with traditional materials, saves energy, and utilizes rain water. Most of the interior equipment is environmentally friendly too, and it gained the "Environmentally Friendly Service" ecolabel, certificated by the Czech Ministry of Environment.

The idea started with a derelict fram, bought by Veronica in the autumn of 1998 with a vision of a "Centre for ecological model projects for the countryside", a place for sharing practical knowledge. The passive house was inaugurated in October 2006. The project is an example of a unique cooperation of many partners for preparation, financing and realization of the construction.

Dissemination and education

The seminar building of the Veronica Centre serves for education and training of the public and other target groups (public administration, entrepreneurs, craftsmen, scholars,  and students) on sustainable regional development.

The passive house also plays a role of a model of economically and environmentally sound building. It is accessible to expert and general public, and education, information, and knowledge sharing is being organized in the form of open days, topical seminars, and tours, among other things. In 2007, more than 3500 people took part in our model project tours.

It is also possible to get first-hand experience by spending the night in the accommodation part of the Centre Veronica.
