Johannes Pelda is research associate at the HAWK University of Applied Sciences and Arts in Göttingen, where he elaborates options to a more flexible operation of regional energy systems mostly connected with district heating networks. He is responsible for modelling and simulating of these energy systems. Currently, he focuses on renewable thermal energy sources for district heating networks, its performance as well as efficiency. His former work was related to energy efficiency of industry where he conducted energy audits based on DIN EN 16247-1 and implemented DIN EN ISO 50 001. Meanwhile, he gained experiences with industrial and sewage heat potential. Before that, he graduated from the Europa-Universität Flensburg and received his Master degree in Energy and Environmental Engineering. Previously, he studied Environmental Engineering at the OTH – Technical University of Applied Sciences, where he was engaged with analysis of sewage water for the PILLS-Project financed by the INTERREG IV B programme and where he optimised industrial processes.
Kirsten Loewe is research associate at the HAWK University of Applied Sciences and Arts in Göttingen. She works in different projects concerning environmental technology, focused on the production of biogas from various substrates and the purification of wastewater. She is responsible for different coordinative issues in lab and pilot plants, client order handling and drawing up of proposals. Meanwhile, she gained experiences with industrial production processes when working in the chemical industry as a Technical Control officer. Before that, she graduated from the Giessen-Friedberg University of Applied Sciences and received her Diploma (FH) in Environmental Engineering.
Ernst Gebetsroither has been working as a Scientist at AIT Austrian Institute of Technology GmbH, Center of Energy, since 1999. He studied music research and history of art (1990-1991), ecology (biology) (1991-1997) and mathematics and physics (1998-1999), all at the University of Vienna. He focused in his PhD studies on the combination of multi-agent system and system dynamics modelling (2007-2010) at the Mathematics Institute of the University of Klagenfurt (his PhD:“ Combining Multi-Agent Systems Modelling and System Dynamics Modelling in theory and practice.“). He has about 15 years of experience in modelling and simulation and works as a lecturer in this field at the University Vienna. He also has expertise in renewable energy systems as this was the main theme in his magister thesis guided by Prof. G. Faninger. Within 2007-2008 he was funded to work at the Institute of Artificial Intelligence (IIIA) of the „Universidad Autónoma de Barcelona“ by the „All-round Excellence“ Initiative, of AIT. There he worked on Agent-based Simulation. He was leading the project MoZert funded by the Austrian climate and Energy Fund („NeueEnergie2020“) elaborating the effects of personal carbon allocation schemes for the socioeconomic situation of households and the energy system in Austria. Between 2007-2009 he was lecturer at the University of Applied Sciences Technikum Wien (Master course Environmental Engineering and Management). Since 2010 is he also lecturer at the University Graz at the Institute for Systems Science, Innovation & Sustainability Research (ISIS). Main Focus of his expertise is in Modelling and Simulation combining different methods with the integrating GIS data.
Romana Stollnberger is working for the Austrian Institute of Technology (AIT), Center of Energy in the business unit „Sustainable Buildings and Cities“ as Junior Research Engineer since September 2016. She holds a degree for spatial planning from the Technical University of Vienna. During her studies, Romana worked for AIT since June 2014 and also wrote her diploma thesis (2015-2016) with the topic „Industrial and commercial waste heat potential and its usage for an energy efficient urban development in the city of Vienna“. Her main areas of research are sustainable development of cities and regions, spatial energy planning for smart cities and GIS-based analysis of spatial systems.
Roman Geyer is as a research engineer at the AIT Austrian Institute of Technology, Center for Energy, since May 2016. His areas of responsibility include not only scientific collaboration but also leading tasks and projects of national and international projects with focus on district heating and cooling (DHC). Roman has more than five years of experience in development/leadership of projects, both in national and international context. He is mostly experienced in the energy sector with focus on power plants. Additionally, he gained also expertise in the fields’ fiber optic infrastructure and metal industry. Roman holds a master’s degree in Renewable Urban Energy Systems of the University of Applied Sciences Technikum Wien.
Ralf-Roman Schmidt has been working at the AIT since June 2009, where he is responsible for the field district heating networks. He studied production engineering at the University of Bremen with a focus on process engineering and production processes. From 2004 to 2009, he was engaged in the numerical simulation and experimental analyses of thermodynamic and fluid mechanic processes in heat treatment of metals at the IWT Bremen (Foundation Institute of Materials Science), a German research institute. In 2013 he received his PhD-degree in this area.
