Christian Thommessen studied mechanical and business engineering at the University of Duisburg-Essen. Since 2017 he is PhD student at the Chair of Energy Technology and works within a Graduation program for Sustainable Energy Systems in Neighborhoods by the Ministry of Culture and Science of the German state of North Rhine-Westphalia. His studies deal with district heating systems and the optimization of operation – from supply through distribution to consumption.

Abstract:

There are many requirements for district energy systems. Urban planning has to meet the expectations of various disciplines and business actors in order to implement energy-efficient supply solutions both in new buildings and in existing urban districts. Smart district energy concepts are characterized by their technical feasibility, legal admissibility, social acceptance, economic efficiency and sustainable supply security. If a district energy concept does not fulfill one of these aspects it will not be implemented or at least an implementation will be difficult. Furthermore, after planning and implementation, the requirements must be satisfied during operation as well.

State-of-the-art research focuses on single topics. The contribution of my presentation is a review of all general requirements and their interdependencies regarding smart district energy concepts.
