The House of Energy, one of the world’s most sustainable buildings located in Bavaria is the first of its kind, a mixed residential and commercial project that has met the criteria for a Passive House Premium certification. On 14 and 15 November 2015, the building will open its doors to the public within the framework of the International Passive House Days 2015, so that everyone has the chance to experience its structural quality and excellent indoor air quality. The Passive House Premium certificate will also be officially presented to the building owners at this event.

 

The project was developed by the building services company Airoptima, which now has its headquarters in the world's first Passive House Premium. With a total area of about 900 square metres, the House of Energy also has space for the operations manager's flat, a training centre, and a permanent exhibition on the topic of "Construction and Refurbishment". The three-storey solid construction was certified by the company Herz & Lang.

 

 

Background

 

The Passive House Premium class was launched together with the Passive House Plus in April 2015 with a new version of the design tool PHPP. In both cases the building owner is offered reliable guidance when combining efficiency with renewable energy. However, energy generation and demand are calculated separately – in many climate zones, renewable energy is mostly generated in summer, but the greatest demand usually exists in winter, and seasonal storage would be associated with losses. For the individual energy applications, PER (Primary Energy Renewable) factors are specified which state how many kilowatt hours of renewable primary energy have to be generated for one kilowatt hour of energy that is required.
