Abstract
The Nordic single-family house renovation market is dominated by a craftsman based
approach with individual solutions, traditional warehouses ”do-it-yourself-shops” and some
actors marketing single products. To speed up the implementation of sustainable renovation
of single-family houses there is a great need for full-service packages including consulting,
contract work, follow-up, financing and operation and maintenance. There are few Nordic
examples of such service models for renovation of single-family houses which entered the
market recently. The success of these concepts is yet to be evaluated.
One successful full-service package described in the report is a campaign by an energy
company in Sweden who convinced 78% of 456 owners of houses with resistance heaters to
connect to its biomass based district heating network. The campaign was successful because
of its package offer and information provision with emphasis on economic aspects and
functional reliability.
The existing technical renovation concepts, typically focussing on application of only a few of
the available technical solutions, have not been successful in realizing large scale energy
efficiency gains. Renovation of single-family houses might be carried out based on design
solutions with good combinations of the possible range of technical solutions including e.g.
“passive (insulation) measures” and “solar measures” in order to reach a low primary energy
level. Key aspects of reaching a low primary energy level in connection with renovation are described in the form of typical energy renovation measures and technical principles of low energy renovation including recommended extent of measures. Full service and technical renovation concepts should make it easy, simple and secure for the consumer to invest in a low energy renovation of their house. The building sector needs easy to use knowledge and initiatives which ensures that they can offer solutions which fulfil the demand for quality, economy and a simple process. To speed up the implementation of sustainable renovation of single-family houses, society needs to stimulate the process including better incentives structures, e.g. increased tax on energy and/or subsidy programmes. Combined with an outlook for rising global energy prices, sustainable renovation of single-family houses then has the potential to become an important market area
in the future
