How can energy efficiency be a part of a wider restoration of a housing area built between 1945 and 1975 (part of the Swedish ‘million program’)?
The purpose of this rapport is to increase the knowledge of the communal savings associated with increasing the energy efficiency of existing building.
And to inform and present the economic benefits and disadvantages around the investment decisions of increasing the energy efficiency of the Swedish ‘million program’.
The method builds on a literature study that has been combined with interviews to make sense of and gather information about how increased energy efficiency can affect socioeconomic aspects.
Implementing energy efficiency provides great potential for the business economics and social environmental improvements, but the decisions are many and the possibilities vary among house owners.
There are more than energy investments to be considered in the rehabilitation of the Swedish ‘million program’. Most of the investments are difficult to make precise calculations and absolute assumptions about. The two big society associated savings aspects are the benefits for the tenants and the potential energy savings. In addition there are savings associated to care, tax revenues and
immigration. The abstract savings are there, but without insight into the subject they may be hard to detect.
The commune can through elderly accommodation save SEK 350 000 every year for each person. The state can earn approximate SEK 240 000 on each apartment in tax revenues from the restoration. And the local residents can get a new fresh neighborhood. In addition, the energy savings on a building from the ‘million program’ saves 137 SEK/m

The energy efficiency should not be seen as an alternative when restoration of a building is being done. Instead it should be seen as an obvious thing to do because the cost is low compared to the investment - both for the residents and the society.
