Renovating million homes program to Umeå municipality construction requirements for energy consumption (English)
A lot of houses built during the Million Homes Programme are in need of major renovation. Today’s technology and materials are better than in the 60’s and 70’s. Both Swedish government and the European Union have set climate goals regarding energy consumption by 2020 and 2050. Achieving these goals would require better standards in buildings than the Building regulations demands, such as Umeå municipality’s construction requirements for new buildings.
The report aims to investigate if a renovation of apartment buildings from the Million Homes Programme can reach Umeå municipality’s construction requirements. The goal is to create detail solutions which meet the energy demands. Three important components to reach the demands are U-values, thermal bridges and air tightness. Different constructions have been tested in these three areas by calculations with Isolerguiden Bygg 06, Isover Energi 3 and literature studies.
The results of the calculations show that a lot of energy would be saved with a renovation of the building envelope, from 139 kWh/m2 to 42 kWh/m2. It’s possible to achieve sufficient U-values and reduce thermal bridges in all areas except the foundation. It should be possible to refurbish the foundation but it’s difficult to measure with the methods and tools available. With a major renovation it should be possible to make an old building as energy efficient and air tight as new constructions according to studies and experiments.
