One-stop-shop service for sustainable renovation of single family house : Summary Report

The Nordic project “Successful Sustainable Renovation Business for Single-Family Houses (SuccessFamilies)”, with participants from Denmark, Finland, Norway and Sweden, deals with development of business models for full service energy efficient renovation of detached houses in Nordic countries. The background to this project is that the majority of these houses are more than 30 years old and need to be renovated, which provides opportunity for implementation of energy efficiency measures. The renovation market is dominated by handicraft-based individual solutions. There is a need for onestop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, independent quality control and commissioning, and financing. There is a significant business potential for such a model as the volume of renovation market for single-family houses can reach hundreds of million Euros per year in each Nordic country. The project team analysed emerging business models to offer full-service renovation packages in the Nordic countries. A comparative assessment shows that different types of actors (renovation company, insulation company, energy utility, building product warehouse) can provide such a service. There are differences in how customers are contacted, while the similarities are more on how the service is provided. A main challenge is how to secure independent advising. Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. Various options to overcome the barriers to promote energy efficient renovation of detached houses are discussed in the final report.
