Between the years of 1965 and 1975 some one million apartments were built on an industrial scale in Sweden. The intent was to provide the quickly growing population with modern housing featuring reasonably sized apartments and good functionality; such as central heating and modern kitchens and bathrooms.
Some forty years later many of these large multi-family dwellings are in dire need of substantial renovation and improvements to extend their life expectancy and improve their desirability.
Improved energy performance is under the current circumstances a demand from both the national government, EU and the property owners. Previous historical experiences from trying to reduce energy use in buildings has made concerned parties aware that care must be taken to, among other things, avoid reductions in indoor air quality and minimizing the risk of moisture damage in structures.
This paper is an overview of some common features of these Swedish multi-family dwellings and some of the approaches and problems related to improving their energy efficiency, while trying to avoid negative impact on the indoor climate and maintaining components in a functionally sound state.
Included is also a brief overview of some currently ongoing research projects related to the improvement of the 1965 to 1975 Swedish multi-family dwellings.
The eventual challenge is to find a way to adapt these buildings in a controlled manner so that they will be energy efficient, economical, functional and provide the residents with an appropriate indoor environment while being aesthetically pleasing.
