This thesis investigates energy efficiency improvements of an apartment building located in Tunabackar, Uppsala. The residential area is owned and managed by Uppsalahem AB. Investigated measures aim to reduce energy use in buildings from the 1950s. The survey can hopefully provide insights to Uppsalahem for future renovations. The project has focused on measures to preserve cultural values in the area. A general cost analysis of the measures was also conducted to find out whether the measures were financially profitable investments. The results are based on simulations, site visits, thermography and cost calculations. The results show that the reference building's energy use decrease by 25-57% depending on renovation package. Package 1, consisting of window renovation and additional insulation of attic floors. The largest heat savings are achieved with package 3. The package consist of exhaust air heatpumps, solar cells and solarthermal panels and reduces the heat use with 57% compared to the base model. Based on the results, package 2 is recommended for installation. Package 2 consists of exhaust air heatpumps and solar cells, and the package reduces the energy use with 53% to a cost of X kr. The cost estimate differs between different action packages with over 2.5 million between the cheapest and most expensive package.
