Urban Energy Systems  <<

Many municipalities have decided on ambitious goals to become climate neutral within the next few decades. Although Germany and most other European countries have significantly and measurably increased their renewable energy fraction in the electricity – less so in the heating sector, urban energy demand has not decreased significantly.

On Thursday, June 2, experts convent at the German Center for Research and Innovation (GCRI) in New York to discuss research on energy efficiency strategies and urban refurbishment scenarios. The speakers addressed city-wide energy demand and consumption mapping and monitoring, planning tool development based on 3-D city models, the optimization of building performance by advanced automation concepts, and the integration of renewable energy sources in urban energy networks.

Prof. Charles J. Vörösmarty, Professor in the Department of Civil Engineering and Director of the Environmental CrossRoads Initiative at the City University of New York, provided a global outlook on urbanization and densification problems and their relation to energy. He discussed the impact of heat waves and climate change on cities, resulting peak power increase, and energy supply solutions.

He was joined by Prof. Dr. habil. Ursula Eicker, Professor at the Centre for Sustainable Energy Technology at HFT Stuttgart University of Applied Sciences in Germany. She presented an analysis of the urban energy status quo in Europe, especially in the building sector. She described efficiency scenarios in the building stock and in investment and energy life-cycle costs. Further, Prof. Dr. Eicker spoke about local renewable generation potential. Lastly, she presented the first net zero-carbon case study city Wüstenrot as an example. Prof. Dr. Eicker is a physicist, professor, and research director at the HFT Stuttgart. Her research emphasis is on urban energy systems with low-energy buildings and renewable energy integration, energy management, control and simulation, and the role of solar technologies in sustainable urban development. She currently manages several international research projects on energy-efficient cities and renewable energy supply systems.

Michael Bobker, Director of the CUNY Building Performance Lab and Senior Fellow at the CUNY Institute for Urban Systems, spoke about the New York energy infrastructure, especially with regards to heating and cooling. He discussed the transformation of the heating sector from steam to electricity-based supply, focusing on the consequences for renewable supply by solar and wind farms.

Prof. Dr. Volker Coors, Professor of Geoinformatics and Computer Science at the HFT Stuttgart University of Applied Sciences, discussed smart data for smart cities. He spoke speak about the role of IT for urban modeling and urban optimization. He also described 3-D city models and services based on international standards. His research focuses on 3-D geographic information systems and information logistics, in particular data management and visualization of large 3-D urban models. He is currently involved in several international research projects and provides supervision in the areas of 3-D GIS systems for urban energy demand modeling and city model interfaces and information management for the CI-NERGY (Smart Cities with Sustainable Energy Systems) project, a Marie Skłodowska-Curie Initial Training Network (ITN).

This event was co-sponsored by the German Center for Research and Innovation (GCRI) and HFT Stuttgart University of Applied Sciences. The German Center for Research and Innovation provides information and support for the realization of cooperative and collaborative projects between North America and Germany. With the goal of enhancing communication on the critical challenges of the 21st century, GCRI hosts a wide range of events from lectures and exhibitions to workshops and science dinners. Opened in February 2010, GCRI was created as a cornerstone of the German government’s initiative to internationalize science and research and is one of six centers worldwide.
