Zero Emmission House

"Making the first inhabitable zero emmission (ZEB-OM) single family house in Norway"

In 2017 the ambitious owners of Bråtaveien 3 set on the agenda to show that building a zero-emission private house (ZEB-OM) is achievable for middle class couple with children. The two floors, 200sqm compact volume contains a single-family house and a rental unit.

The building is placed in the northern side of the site, maximizing the garden to the south. East-west orientation with its long façade directly towards south, aim to harvest as much solar energy as possible. Both southern roof and façade are covered with PV panels. The second-floor cantilever allow winter sun to penetrate and warm up the concrete thermal mass but keeping unwanted summer sun away.

The heart of the house is a 7,5m high, open central winter-garden that unite the house’s rooms both horizontally and vertically. Emphasis has been on finding good area-efficient solutions and planning an integrated energy concept.

"Building a house that produces more electricity than it consumes in one year in a colder part of the world is, as we see it, proof that this is not only a concept that can be done, but that should be the standard for ensuring a sustainable housing situation in Norway."  Owner

Environmental solutions used in the project, are among others:

  • CLT construction.

  • Geothermal heat pump.

  • Decentralized balances ventilation directly inserted in the external walls with integrated heat recovery

  • G-value for windows of 0.55.

  • Energy recovery system from greywater

  • Energy-efficient LED lighting is required

  • photovoltaic system connected to the public electricity grid

  • shower heads with low water consumption.
