The following study is part of a research project at Uppsala University. The purpose of the research project is to investigate careful energy efficiency measures, which can be implemented in 20th-century single-family housing, in order to contribute increased knowledge on how the single-family housing stock can be made more energy-efficient. This report contributes knowledge about single-family housing from the 1960´s in Uppsala, with a focus on measures that make the buildings live up to the requirements of the Swedish building regulations (BBR 29). The report covers two single-family housing areas in Uppsala, Sunnersta and Valsätra, for each area a typical house has been selected for further studies. One has a wooden facade and the other has a facade of bricks. The proposed renovation packages are divided into three levels: MIN, MAX, and MIX, which describe the scope of the measures. The first package of measures (MIN) includes milder changes in the facade and the plinth. The second package of measures (MAX) includes major procedures in all parts of the building to ensure maximum energy savings. The last package (MIX) is a combination of the two action packages MIN and MAX. All the packages are simulated in BIM Energy and the simulated packages of measures for both type houses meet the energy performance requirements in BBR of 90 kWh/m2Atemp and year. However, only the action packages MAX and MIX for type house I meet the requirement regarding the U-average of 0,30 W/m2K. In the package MAX, both type houses achieve energy classification A, while the packages MIN and MIX for both type houses achieve an energy class of at least C. The energy prime is reduced by milder procedures in the framework of the buildings. To lower the U-average requires major changes in the design of the buildings. The requirement for the U-average doesn’t need to be achieved to have an energy prime which is in accordance with the requirements from the BBR. The type houses meet today’s energy performance requirements and can be adapted to stricter requirements in the future. Type house I has a greater opportunity to meet future U-average value requirements than type house IV. The action packages can to a high degree be used in the reference areas. The MAX and MIX packages have a greater impact on the character of the area in Sunnersta and Valsätra, while the MIN package to a greater extent takes the surrounding area into account
