300 apartments - Alingsås, SE
Redevelopment of Brogården
|
In 1963 - 1975, one million homes were built in Sweden. Brogården was built in 1971 - 73, and was the last residential area in Alingsås built under the million-home programme.
The apartments are of a high standard, with generous and easily-furnished rooms, but are regarded as quite draughty. Problems include bricks in the facade being damaged by the freezing winter conditions and having to be replaced. The rent for the apartments includes heating, hot water and electricity. This means that tenants have no idea of how much energy they use, which means that there is no financial incentive for them to reduce their consumption.
It is now time to carry out a comprehensive upgrading, and the decision to renovate the buildings using passive house technology is a natural one, since climate issues currently pose the greatest threat to the environment.
The construction work started in March 2008 on one building in Knektegårdsgatan 35. Once the first building has been completed, an evaluation will be carried out before we moving on to renovate 300 apartments in total at Brogården.

Photo of Brogården. Here the roof has been fitted with an extra layer of loose wool insulation and made airtight with the installation of paper insulate, which covered the sides, as well. A three centimeter thick layer of insulation has been placed on top, followed by the original roof, which was retained as it was in good working condition. The eaves were extended after the renovations, since suspended balconies had been installed and a new (thicker) wall constructed. Photographer: Joakim Carlander
