Alternative renovation systems to reduce the transmissionlosses on buildings from 1965-1975 (English)
Abstract [en]

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression for

buildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to the

largely transmission losses of these buildings. Many of the buildings from this period have similar constructions and therefore

the same techniques can be used to renovate several of them. This project only considers the climate scale, although there

are many more factors to concern for to efficient the buildings of Miljonprogrammet.

This thesis presents examples of renovations carried out using two of the three renovation systems.

The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,

consumption of energy and the investment costs. The new U-values the building is given is matched to the values of

recommendation for passive houses. Our reference house is a two story apartment building, located in the village of

Lammhult, with brick facades at the ends and plaster at the long sides. One of the long sides contains balconies. The three

systems are additional insulation, prefabricated additional insulation and replacement of the facade. We consider which

renovation systems are best in different conditions, also considering the treatment of the tenants.

The result of the study shows that with additional insulation and prefabricated additional insulation the buildings transmission

losses will be major lowered. The investment cost and payoff time for the prefabricated version is much lower. If the standard

of passive house is wanted the replacement of facade technique should be used. This method requires that the tenants move

out during the renovation work. The investment cost for this method is significantly higher but the payoff time is equal with the

additional insulation methods payoff time
