This thesis investigates the current state of information sharing between district heating (DH) operators and customers in Sweden, with a focus on addressing the lack of coordination between the primary (operator) and secondary (customer) sides of DH systems. The study aims to investigate existing research on information sharing, examine the benefits of two information-sharing scenarios, and provide insights and recommendations for future partnerships between operators and customers. The study utilises qualitative methods consisting of semi-structured interviews with industry experts, which include district heating system operators, apartment rental companies, and energy management companies. It is complemented by a review of previous studies on DH systems. The results underscore the importance of enhanced communication and data exchange for optimising DH performance and sustainability. The study shows a lack of information sharing between district heating operators and customers, pointing to ownership issues, perceived lack of value, absence of suitable business models, and resource constraints as primary barriers. Insights and recommendations provided by stakeholders offer actionable strategies for facilitating future information sharing. Simplifying processes, developing transparent data management systems, and creating suitable business models are seen as key priorities.
