The aim of the project is to create a sustainable development platform for sustainable urban development with focus on the housing issue and clear barriers for SME growth in the housing sector.The project goal is to establish a new and lasting collaboration platform for sustainable urban development with focus on the housing issue, and to clear barriers for SME growth in the housing sector.Participation in the development of a new and sustainable collaboration platform for sustainable urban development. The project group discusses how and where in the project SME or client should first participate based on SME’s needs and communicates contact with the respective partners. The target group will be able to benefit from and use the results of the project by being part of the collaboration platform. The continued management of the platform will be discussed and developed by the steering group during the project. More partners than before are engaged in each activity. The project will develop a model with criteria for sustainable housing that municipalities and other regional actors can use to contribute to a more sustainable housing. More companies will have access to test infrastructure in the test bed that has been started together with Stockholmshem in Solberga The innovation procurements started in stage 1 will be completed in stage 2. Further innovation procurements within, for example, exterior walls with improved energy performance, waste heat recovery and sustainable local energy systems To drive and develop the region’s work to form a cluster in sustainable urban development within the framework of the EU’s Smart Specialisation Strategy Sharing knowledge from housing research and sustainable community building to SME and the county’s actors Business will participate in the project. More companies gain access to test infrastructure through the WP test bed. Innovation procurements are initiated by housing companies’ challenges and answered by sme. Knowledge must be transferred between researchers and sme. Among the expected results are at least 2 case studies with a documented method that demonstrates CO2 reduction and reduced segregation established cooperation for communication between the project and its collaboration partners, and from these to SME and the housing sector. 1-2 new test beds with low-carbon technology started more SME companies have entered public and private procurement at least 3 activities established that can contribute to a co-ordinated and coordinated sustainable housing development in the Stockholm region at least 5 activities and educations that increase the level of knowledge for actors in the housing sector For example, are expected long-term effects that Green BoStad Stockholm will be an established working method and platform in sustainable urban development in the region where collaboration between industry, academia, public sector and civil society prevails. GBS will contribute to players in the Stockholm region using innovative, low-carbon technology in new builds, conversions, renovations and temporary housing. After the programme period, the role of innovation procurement has been strengthened, resulting in lower thresholds for SME companies’ entry into public and private procurement.
