Using a One-Stop-Shop Concept to Guide Decisions when Single-Family Houses are renovated

One way of reducing the use of fossil fuels in Denmark is to explore possible energy savings in the building stock, especially the large number of single-family houses built from 1960 through 1980. Energy renovation in this housing segment is progressing slowly. The aim of this project was to determine how a one-stop-shop (OSS) or full-service concept could be used to guide the extensive energy renovation of single-family houses. The purpose was partly to identify the benefits and disadvantages of using the concept and partly to evaluate the potential of the OSS concept for increasing the degree of renovation. The scope of the project was to carry out renovations on up to three houses. The project revealed that the concept on its own was not enough to motivate the house owners to engage in extensive renovation. However, interviews with the house owners indicated that the renovations that took place had probably been expanded and improved with the use of the concept and that the renovations in general benefitted from an independent adviser.
