Sweden’s first energy producing house

The Rockwool Group has lengthy and well-documented experience of building well-insulated low-energy and passive houses in a number of countries in Europe. Now the time has come to take the next step with the energy-plus-house Villa Åkarp, which is under construction north of Malmø, Sweden. When completed, it will generate more than one and-a-half times as much electricity as it uses.

Energy consumption
The heating system in Villa Åkarp consists of a combination of solar panels, a storage tank and normal radiators. The 10 m2 solar panels on the roof will heat the house and provide hot water. 32 m2 of separate solar cells will produce electricity all year round. In the summer excess electricity amounting to 4,000 kWh will be sold to an electricity company. During the winter, 2,600 kWh will be bought back.

Insulation
One type of insulation being used in Villa Åkarp is a three-layered external wall system of 540mm façade and stone wool insulation, called Flex Systemvæg, which prevents thermal bridges around doors and windows. A balanced ventilation system helps to ensure that there is fresh air in the house and, together with the insulation, creates a good indoor climate, low heat consumption and stable temperatures throughout the building
