Dr. Clemens Rohde

Fraunhofer Institute for
Systems and Innovation Research ISI

Coordinator of Business Unit Energy Efficiency

Experience

Clemens Rohde studied civil engineering at the Technische Universität Darmstadt and graduated at the end of 2002. From 2002-2007 he continued to work at the TU Darmstadt as a research assistant and was involved in national and international projects in the field of environmental engineering. His focus here was on waste management and technology as well as life cycle assessment in product development and waste management. In 2007 he obtained his PhD and then worked for 3 years as a senior researcher and faculty manager in the faculty of civil engineering and geodesy at the Technische Universität Darmstadt. 

He joined the Competence Center Energy Policy and Energy Systems at the Fraunhofer Institute for Systems and Innovation Research ISI as a research assistant in September 2010. He has been the coordinator of the Business Unit Energy Efficiency in the Competence Center Energy Technology and Energy Systems since January 2012.

His research areas include assessments of energy efficiency potentials in industry, private households and the tertiary sector, the analysis of technological and organizational measures to improve energy efficiency in the aforementioned sectors and energy efficiency indicators on the national and international level.

Clemens Rohde is an internationally recognized expert on energy efficiency with numerous presentations and publications on the topic. He is consulting the German federal government, the European Commission and the IAE.

Academic Teaching

2009-2012, he taught the module “Planning, construction and operation of waste treatment facilities” at the Technische Universität Darmstadt.

Since 2012, he has taught  “Energy and Resource management“ as part of the project seminar “Basic Principles of Foundations in Planning, Design and Construction“ at the Technische Universität Darmstadt.

Since 2013, he has taught the Energy Efficiency module at the Technische Universität Darmstadt.
