Processes for ambitious energyefficient housing renovation are at present often too fragmented between many SMEs and clients have difficulties handling all information. This brings communication, planning, coordination and execution problems. It is also difficult for customers to find single responsible parties offering integrated housing renovation as a service. Since innovative client-oriented services are already emerging in various European countries, also Belgian enterprises should explore business development opportunities for more client-oriented housing renovation. The potential for so-called “One Stop Shops” that unburden the customer was explored in a European project, which led to defining tools for business modeling of customeroriented integrated housing renovation services. The developed tools and new networking methods were recently used in the international “Business Zoo” workshop to explore business development opportunities and barriers together with Belgian and international enterprises. The experiences of ten working groups during this workshop are explained in this paper. The working groups detected various opportunities and barriers for Belgian business model development for integrated housing renovation as a clientoriented service. They developed initial business model canvases for integrated housing renovation.

How do we get from demonstration projects to a volume market for very low energy demand in advanced housing renovation? The contributors to this report have been working with this issue for many years. Some worked in both IEA SHC Task 28 Sustainable Housing (2000-2005) and in SHC Task 37 Advanced Housing Renovation with Solar and Conservation. This work resulted in the handbook Business Opportunities in Sustainable Housing (from Task 28) and in this booklet. Building stock analyses from Task 37 show that many countries have a huge theoretical potential for reducing the energy consumed in the existing building stock. The question is: How do we speed up the transition from demonstration projects to volume market? This report looks both at a traditional market development perspective and interventions by public actors. By doing this, the report aims to provide a better understanding of what drives advanced housing renovation, and provides a reference document designed to inform and recommend directions for policy makers and central decision makers. For successful market development, it is necessary that the right private and public actors cooperate, coordinate their measures and perform them at the right time. Those saying that the market is not ready for this are quite right if they mean the majority of the market. Any new product or service has to be adopted first by the innovators in the introduction phase and thereafter the early adopters in the growth phase before it can reach the early majority in the volume market. This applies to both the supply and demand side. This booklet investigates these three phases through four marketing perspectives: attractiveness, competitiveness, affordability and availability. Separate chapters highlight the driving forces, barriers and critical success factors that are recognised in each phase. This chapter is a short summary of the findings. To fully exploit the potential of this report it should serve as input for a strategic process carried out by public or private actors which consider taking an active part in developing the market for Advanced Housing Renovation.

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.
