The House of Energy. First Passive House Premium certificate
Much better known as the House of Energy, the building is sited in Germany. The building is a mixture of residential and offices building. It has a surface of 900 sq meters and also space for the operations manager’s flat, a training centre, and a permanent exhibition on the topic of “Construction and Refurbishment”.
The heating demand is only 8 kWh/m2 and has at the same time a photovoltaics surfae of 250 sq meters. To obtain the Passive House Premium certificate, the house has the following features:
- Triple-glazed windows
- Excellent level of thermal protection

If extra electricity is generated, the surplus is fed into the grid. That means, not only has the building a low energy consumption, but it also generates electricity for other buildings.
Both Passive House Premium and Plus were launched on April 2015. The energy requirements to obtain the Plus certificate is 45 kWh for overall reneable demand and at least the generation of 60 kWh/m2 with renewable sources. In the case of Premium certificate, the energy demand is 30 kWh/m2.
