HFAB:s dwelling stock on this area are going through a bigger renovation and in relation to this they are looking on the possibilities to make this building more energy efficient. That is why this examination paper has as purpose to answer the question if it is possible to make slab blocks built in the sixties more energy efficient. This is done by calculate energy efficient measures on a chosen apartment block at Maratonvägen in Halmstad, in an energy and expense perspective.</p><p>Method</p><p>The examination paper is based on different methods, mainly calculation but also qualitative conversation studies, economic calculations and literature studies. Energy calculations has been done with the computer program VIP+, which is doing the calculations based on a energy balance in consideration to the building construction. The calculation in the program is also done with consideration for climate and thermal bridges. The investment calculation is done with the pay off-method. The litterateur study is built on searches in the databases HULDA, LIBRIS and Internet. Since the development in this particularly area is progressing fast we have focused on information published after the year 2002 and forward. The dialogue interviews are founded on an interview guide. This to collect as much information as possible and be able to adjust the questions depending on the answers.</p><p>Conclusions</p><p>The conclusion that is presented in this examination paper is among others that there are good possibilities to make slab blocks built in the sixties more energy efficient. VIP+ is reliable as a calculation method for this examination paper. A change of a window with u-value 0,9W/°C is the most energy-efficient measure that we calculated and that solar-heating is a good way to provide the building with hot water.</p><p>Key word</p><p>Energy-efficiency, VIP+, energy-efficiency measures, slab blocks built in the sixties, Maratonvägen,</p>
