PEB Key Features
- N of dwellings: 12 units
- N of floors: 3
- Average surface area per apartment: average 60 m2
- Outdoors and common areas: parking with charging option for EVs, and green area around the building
The building is part of the ‘Assisted living and welfare technology’ programme. Bærum municipality financed the construction, but users can buy or rent their apartments. There are 12 units with one occupant per unit. The building is managed round-the-clock by onsite staff, 3 during the nighttime and about 12 during daytime.
This demo is characterised by a solid wood structure built in a zero-emission construction site. The building is classified as BREEAM Excellent, the worldwide leading assessment method for sustainability of buildings. The building has 3 geo-thermal wells as energy source and a 20 kW heat-pump. The heat-pump works in combination with an electric boiler which provides hot water and water-based floor heating. There are photovoltaic panels (23 kWp) and battery for storage of energy. Balanced ventilation with heat recovery supplies each apartment and common area with preheated fresh air. Automatic window screens prevent overheating.
