<p><p><p>The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression for</p><p>buildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to the</p><p>largely transmission losses of these buildings. Many of the buildings from this period have similar constructions and therefore</p><p>the same techniques can be used to renovate several of them. This project only considers the climate scale, although there</p><p>are many more factors to concern for to efficient the buildings of Miljonprogrammet.</p><p>This thesis presents examples of renovations carried out using two of the three renovation systems.</p><p>The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,</p><p>consumption of energy and the investment costs. The new U-values the building is given is matched to the values of</p><p>recommendation for passive houses. Our reference house is a two story apartment building, located in the village of</p><p>Lammhult, with brick facades at the ends and plaster at the long sides. One of the long sides contains balconies. The three</p><p>systems are additional insulation, prefabricated additional insulation and replacement of the facade. We consider which</p><p>renovation systems are best in different conditions, also considering the treatment of the tenants.</p><p>The result of the study shows that with additional insulation and prefabricated additional insulation the buildings transmission</p><p>losses will be major lowered. The investment cost and payoff time for the prefabricated version is much lower. If the standard</p><p>of passive house is wanted the replacement of facade technique should be used. This method requires that the tenants move</p><p>out during the renovation work. The investment cost for this method is significantly higher but the payoff time is equal with the</p><p>additional insulation methods payoff time</p><p> </p><p> </p><p>.</p></p></p>
