Sammanfattning: Modern energy saving technologies are become increasingly mature, easier to implement and financially profitable. Both the European Union and the Swedish government have directives with goals regarding energy savings for the year 2020 and 2030. Here, making buildings more energy efficient plays a large role as around 40% of the total energy usage in Europe can be related to buildings. Constructing new, nearly zero energy houses is currently very popular, but as a vast majority of all buildings in a country like Sweden are older buildings, built before 1980, a majority of the used energy will come from these buildings. Hence, there is plenty of incentive for carrying out energy saving actions and investments in older buildings. From previous research and interviews with energy consultants, it can be concluded that energy saving actions are not being carried to the extent that is possible. This thesis aims to find out why this is and mainly what the main obstacles are when implementing energy saving solutions in older buildings. A case study, consisting of eight interviews with energy consultants and real estate owners was carried out in order to get an understanding of the current situation and the different stakeholders views on this issue. The results showed that, at least in the represented cases, there is a will among real estate owners for moving forward with energy saving. An understanding has also recently emerged where most real estate owners realize that there are great financial incentives connected to implementing energy saving solutions to current, older buildings. However, increased will of making a change has not yet resulted in a majority of buildings having installed energy saving solutions. One factor for this is that each building is its own individual case and therefore needs to be handled individually due to different conditions and are therefore suitable for different energy saving actions. Other factors include lack of technical and financial understanding among some real estate owners, slow decision making processes and ownership types. The research explores theories related to decision makings to provide a comprehensive overview regarding the current situation of energy saving in Sweden, as well as a contribution to the theoretical literature regarding decision making
