In this study, efforts to improve energy efficiency in seven housing cooperatives associated to the citizens' initiative HS2020, were studied. The aim of the study was to identify and compile the energysaving measures that have been carried out by the housing cooperatives since 2013. Furthermore the study aims to investigate how much the presented measures can lower the energy consumption. Two of the housing cooperatives served as examples and the expected saving from the energy saving measures were investigated using the simulation program VIP Energy. To better understand the motives and incentives for the work, interviews were made with the board members of the housing cooperatives. The results of the study show that four out of the seven investigated cooperatives have already reached the goal of a specific energy uselower than 100 kWh/m2/year. The most effective energy-saving measuresare the installation of exhaust air heat pump and the lowering of the indoor temperature. The simulation results for the installation of heat pumps showed that the heating demand was reduced by 55.4 percent, and the specific energy consumption was reduced by 30 percent. In summary, the HS2020 is on the right track to reach the goals set for 2020, but further work is required to get there. It is of utmost importance that the cooperatives strengthen their expertise in energyrelated questions, and HS2020 has an important role in this work.
