Gallery: Arlevagen is a Charming Low-Energy, Green-Roofed Housing Devel...

 
Each lot is oriented to the east and west, and each home is placed to the northernmost edge to provide a large south-facing yard.

Arlevagen is a development of 8 houses located on a hillside in Floda with beautiful views of lake Sävelången. Helhetshus designed the development in order to offer affordable, energy-efficient, modern homes. Each lot is oriented to the east and west, and each home is placed to the northernmost edge to provide a large south-facing yard. The homes sit half on the ground and half stilted on the hill, which creates dramatic volumes inside and better views out towards the lake. A low-maintenance sedum roof tops off each house to provide extra insulation and water infiltration.

The homes are roughly shaped like boomerangs and are angled towards the south to capture sunlight. A car port and storage building sit on the north side of each house connected by shared roofs that create protected decks at the main entrances. The houses come in 4 different sizes: 127 square meter or 141 square meter ground floor area, with or without a loft of 45 square meters. Inside, the private rooms and bathrooms are situated on the west side, and the public spaces (laundry, kitchen, dining and living room) are on the east. A central staircase leads up to the lofts, which overlook the living areas. The interiors are flooded with lots of natural light, and the bright walls and floors reflect that light throughout the houses.

The homes feature wood construction with 350 mm thick walls, which are coupled with extra insulated slabs and roofs to make them well-insulated, low-energy residences. Each house also features a heat-exchanging system that reduces total energy use to less than 10,000 kWh/year.

    The Design seems great. It is supposed not to be only power-saving house, functionality and aesthetics are critical for marketing such initiatives. It is mentioned that it is affordable, but how? I would like to know the costs of building compared with costs of the regular houses of the same level in different areas in Sweden. that will give an idea about how affordable they are.

    Bridgette Meinhold, green roofs like this are wonderful! I would love to know more about the insulation throughout the building, though. What is the air exchange rate? Because in a cold climate like Sweden you need metrics to measure the building’s tightness. Sustainable design uses highly efficient, low-resource impact materials that durably maintain the building envelope integrity over time; reducing energy needed to heat and cool its space.
