In Ålidhem in Umeå there is a transformation to a sustainable neighborhood, with its own solar cells and environmentally friendly insulation methods. Within the project Umeå University, Umeå Energi, Umeå municipality and the housing company Bostaden AB cooperates and in the end they will create one of the biggest solar cell facility in Sweden. Now, the solar installations will be completed as the housing company Bostaden AB has set up solar panels on the roofs and balconies.
Electricity generation higher than expected
The housing company Bostaden AB has set up solar panels on the roofs and balconies of two blocks in Ålidhem, and it turns out that the electricity generation is higher than expected. The solar parks total electricity generation is expected to represent more than a third of the building electricity needed in the two blocks.
The largest low energy housing construction in Northern Sweden
In 2008, an entire block in Ålidhem burned down. At that time the idea was born to create Northern Swedens largest low energy housing construction in the district, and simultaneously upgrade the buildings that were built during the 60s and 70s.
Three important improvements
Among the improvements planned for Ålidhem, three important points can be highlighted.
Environmental sealing methods
In Ålidhem, the municipal housing company Bostaden AB, will reduce energy use, including the use of environmentally friendly insulation and sealing methods in the existing apartments.
The flat roofs of Ålidhems buildings will be turned into pitched roofs with integrated solar cells. The goal is that the viewers experience of the characteristic flat roofs should be preserved from the ground level. Additionally, solar panels on the balconies are tested.
In a glassed winter garden, the inside temperature will be held comfortable with recirculated return heat from related low-energy buildings.
