Title: Using a sustainable business model for implementing a PED concept in terms of balancing excess heat on a district level: Case study on the district Lilla Bommen, Gothenburg
Abstract: Following the directives of European "Horizon 2020 -10. Secure, clean and efficient energy", an European funded program called “Positive Energy Districts and Neigh bourhoods for Sustainable Urban Development” has been developed. The program aims to integrate and balance the energy system at a district level, as there is a potential of having a holistic perspective regarding a district. Vasakronan, a Swedish real estate company, has high sustainability aspirations. In vesting in technical innovation is one way for them to move towards a decreased energy consumption. This thesis aims to help Vasakronan in their decision making process of implementing a micro-grid solution in the district Lilla Bommen, located in Gothenburg. The micro-grid will balance the recovered heating and cooling be tween properties in the area and thereby contribute to Vasakronan’s long-term goal of transforming Lilla Bommen to a Positive energy district (PED). To visualize and simplify the complexity of implementing a technical innovation such as a thermal micro-grid, a Sustainable Business Model Canvas (SBMC) is used as a tool to organize and understand the challenges and possibilities and how they are interdependent. Besides organizing workshops with Vasakronan, a literature study and a case study were conducted. In addition, three reference projects were contacted in order to gather inspiration for Vasakronan to use in their further devel opment process. Finally, the empirical data was organized, analyzed and compared to the theoretical framework, in order to identify similarities and diverseness. The main findings are presented in this paragraph. The SBMC is a helpful tool for the company and the participants gained a deeper understanding of the technical and business aspects. Additionally, several possibilities and challenges were found in terms of implementing a micro-grid. By utilizing resources that otherwise would have been considered as waste, Vasakronan saves economical and environmental resources. Their properties are valued higher due to its sustainability factors. Even though the micro-grid is a suitable solution, Vasakronan still has many challenges to solve as the project is in an early phase. For instance, legal issues must be addressed, an energy mapping of the area and a price model must be made in order to prove the financially viability of investing in a micro-grid.
