Developing an integrated offer for sustainable renovations

Within an ERANET-ERACOBUILD project, this study investigates the opportunities and barriers to establish a “one stop shop” with an integrated supply side, to counteract the fragmented offer in sustainable renovation of single-family houses and to increase the level of knowledge, skills and innovations. Aspects of providing reliable information and guidance for house-owners are also included. Starting from a survey directed to the Flemish construction sector, we tried to distill the viewpoint and willingness of enterprises to cooperate in such a one-stop-shop idea. The survey concludes that the increase of holistic very low energy renovations is expected in a short time and that a large percentage of companies is willing to work together. However, socio-technical and know-how barriers to accomplish this still remain. With these results - and an analysis of existing websites providing an interface between suppliers and owner-occupants - business models, training and other activities will be set up to establish a one-stop shop model within the continuation of this project. A test case is foreseen
