Welcome Messages Ingo Weidlich (HafenCity University) Dear colleagues, On behalf of the Scientific Committee of the 16th International Symposium on District Heating and Cooling, it is a pleasure for me as Chairman of the Committee to welcome you to participate in the Symposium in Hamburg, Germany on September 9-12, 2018. This symposium is the world’s meeting place for district heating and cooling experts for more than 30 years now. It is one of the most reputed international events for communication of academic and industrial research. We are planning pre-tour, side events and workshops. In 2018, the 16th International Symposium on District Heating and Cooling will be hosted by the HCU Hamburg. District Heating has a strong history in Hamburg since it was first implemented in 1893. Today the district heating network of Hamburg has a length of 812 km with 460.000 connected residential units. 8 Power plants have a district heating output of 5 TWh per year. Ongoing discussion on ownership models for the district energy grids in Hamburg makes the related topics more visible to the public than in other cities. Furthermore, Hamburg is one of Germany’s leading cities for innovation in district energy generation, distribution and sector coupling. Trends of the energy transition in Germany are challenging for Hamburg as well as for many other cities. These trends can be observed also worldwide and they are the most promising precondition for an intensive professional exchange at the 16th International Symposium on District Heating and Cooling. I hope many researchers, stakeholders, and interested people will use this great opportunity to participate with papers, posters or just by attending the Symposium. Please feel invited warmly to already engaged in DHC and anyone who is new in this field to present, listen, learn, debate, network during this special traditional academic Symposium. Welcome to The 16th International Symposium on DHC! Ingo Weidlich Chairman of the Scientific Committee Welcome Messages 7 1. Welcome Messages Gudrum Maass (EUWP) Dear Conference Participants, I would like to personally welcome you to the 16th International Symposium on District Heating and Cooling. This Conference has already a history having been organized for the first time in 1987. Since then it has taken place on a bi-annual basis. The issues which have been discussed, have developed over the time, the most important change was most probably to open up and include cooling technologies in the portfolio. Since 2015, the International Energy Agency Technology Collaboration Programme on District Heating and Cooling (IEA DHC) has been responsible for initiating, supporting and guiding this symposium. This seems to be very appropriate since it is the only non-profit research network with global outreach for technologies relating to DHC. The Programme is dedicated to helping to make district heating and cooling and combined heat and power powerful tools for energy conservation and the reduction of environmental impacts of supplying heating and cooling. The Conference Programme shows that themes will be discussed which are presently at the forefront of the discussion in the energy sector, such as digitalisation and sector coupling. Also, systemic approaches are of increasing importance to address energy issues which leaves room for network technologies such as DHC. Progress in this sector is urgently needed. The findings of the IEA´s latest analysis of Tracking Clean Energy Progress have shown that most technologies are not on track to meet long-term sustainability goals. This is in particular true for the building sector. This Symposium really is an excellent platform to bring together academic and industrial researches from different countries to exchange information on most recent research and development trends in DHC. In the future, it will be increasingly required to reach out to decision-makers, in particular at the local level. Hamburg seems to be a good place to start this dialogue. I would like to thank you for your interest in this Symposium. Without the expertise, knowledge and vision of the participants in such an event it would not be possible to shape the way into a new energy future. Enjoy the Conference Gudrum Maass Chair of the IEA Working Party On Energy End – Use Technologies (EUWP) 8 The 16th International Symposium on District Heating and Cooling 1. Welcome Messages Jens Kerstan (BUE) By a referendum held in 2013, the citizens of Hamburg issued a mandate to local politics to buy back the energy grids, which had been privatized about a decade before, and to strive for an energy supply based entirely on renewable energies. This has put the energy grids and especially the district heating system in our city at the centre of public interest. At the time the 16th Symposium on District Heating and Cooling takes place in Hamburg, the city will be at a crucial stage in the realization of this political agenda. If Hamburg as a city will achieve its climate protection goals depends to a large extent on the decarbonisation of heat supply. In Hamburg, public enterprises have positioned themselves as pioneers of the energy transition. Hamburg’s district heating system is the second largest in Germany, its beginnings dating back more than one hundred years. The possibilities and the difficulties of transforming urban infrastructures are exemplarily visible here, and the Hamburg example shows the importance of municipal action just as clearly as its dependence on given political and legal frameworks. Jens Kerstan was born in 1966 in Hamburg. After graduating from Hansa High School in Bergedorf, he completed his civil service in mobile disability care and in the psychiatric and youth psychiatric service. From 1988 to 1994 Jens Kerstan studied economics at the University of Hamburg. After completing his studies, he worked as a project manager in marketing at Hauni Maschinenfabrik AG. From 1995 to
