Our lecturers have a scientific background with many years of relevant training experience. They combine theoretical input with a strong focus on practical implementation.

Architect Georg Wolfgang Reinberg, (born in Vienna in 1950), is based in Vienna. He studied Architecture at Vienna Technical University and Syracuse University (NY, USA) and received grants from Schütte and Fulbright.

From 1983 till 1986 he was assistant of Professor Anton Schweighofer at the Vienna Technical University. Since 1980 he is working as an independent Architect and runs his own “Ziviltechnikerbüro” since 1985. From 1983 to1990 he was member of “Arge Architekten Reinberg, Treberspurg, Raith”. He is managing his office together with his wife Martha Enriquez-Reinberg, lic. Arch. 2006 the name of his firm was changed into "Architekturbüro Reinberg ZT GmbH". This office which recently has 8 stuff members, is working in design as well as detailed planning and construction management.  Architect Reinberg has realized more than 100 ecologically oriented projects.

In connection with those projects Reinberg has engaged in various research activities.

He won numerous competitions, honours and prizes.

He has taught at Solarbauschule Vorarlberg (1994 – 95). He is lecturing at the Vienna Technical University (since 1995); is visiting Professor at the Danube University in Krems (Solar Architecture, since 1997) and teaches at the University of Applied Sciences in Vienna (FH Campus, since 2013). He is also teaching and giving lectures internationally.

Georg W. Reinberg has published - among others - the following books: “Ecology and Architecture: Architecture by Georg W. Reinberg”, 1998; “Georg W. Reinberg: Solar Architecture”, 2005; “Ecological Architecture-Design, Planning, Realization”, 2008.

Marcus Hummel joined the EEG in 2009. He holds a degree in process engineering (Energy and Environmental Engineering) at the TU Wien. In his diploma thesis he developed a "Model for scenario analyses about the technical possibilities of renewable energy systems" working as a research assistant at the Institute of Industrial Ecology in St.Pölten. One year he studied at the University of Granada in Spain.
His research interests include technical and environmental as well as economical and political aspects of energy systems. Focus lies on the understanding of possible future developments of energy systems using techno-economic modelling approaches. The aim is to help develop sound political measures for the transition to sustainable energy systems in a low-carbon society.
Special working focus lies on industrial energy systems as well as the space heating and hot water in buildings market. Due to the existing overlapping concerning buildings as well as processes his work also covers the service sector. His research topics cover both energy efficiency improvement and renewable energy integration.
Marcus Hummel works on national and international research projects and takes care of project acquisition and coordination.
Since 2010 he takes care of the "Energiegespräche" (Energy Talks) at the Vienna Museum of Technology, a quarterly event for discussing recent energy related topics in public.
Marcus Hummel and Raphael Bointner together lead the Student Chapter of the Austrian Association for Energy Economics (AAEE). The aim is to connect PhD-Students in the field of Energy Economics on the national as well as international level and to foster scientific discussion in the field. Highlight is the organisation of an international PhD-Day once a year at EEG.
