Institute of Energy Efficiency and Sustainable Building


Univ.-Prof. Dr.-Ing. habil. Christoph van Treeck

Short name:



The Institute of Energy Efficiency and Sustainable Building (E3D) consists of around 20 academic and non-academic staff and about 20 student assistants. It belongs to the Faculty of Civil Engineering and covers various disciplines in the scope of engineering and the natural sciences. The interdisciplinary approach allows different perspectives upon the key fields of research.

The Institute mainly focuses on three topic areas: indoor climate and energy efficiency, modeling and simulation, building envelopes and building technology.

Here, the main focus lies on modeling and simulations of building-specific physical processes in the field of energy efficient and sustainable construction and maintenance of buildings, technical installations and urban quarters – including life-cycle analysis. The E3D-team uses and refines IT-based methods in the areas of Building Information Modeling (BIM) as well as geographic information systems (GIS), thermal and energy simulation methods, the object-oriented simulation language Modelica, and multi-physics simulations.

Another focus lies on modeling and simulating user behavior and the impact of climate upon people in terms of thermal comfort. To this end, the Institute also conducts volunteer studies in climate-conditioned rooms. Our work addresses thermal ergonomics regarding vehicle air conditioning in the context of electric mobility, as well as interdisciplinary work on interactions with physiological, psychological, and demographic aspects. In addition, the Institute is involved in projects focusing on energy monitoring.

E3D is based at the new Melaten Campus – within sight of the E.ON Energy Research Center, to which we are connected in the scope of several cooperative projects. As for the aspect of lectures, the Institute offers ten courses in the field of energy-efficient building, for students of Civil Engineering, Environmental Engineering, and Industrial Engineering.

Profile Area ECPE

The provision of sustainable energy and materials is clearly one of the major global challenges which were identified in the future strategy of RWTH Aachen University. The profile area Energy, Chemical & Process Engineering (ECPE) addresses the two most important pathways to achieve this goal: Improvements in energy and material efficiency and the transition to renewable sources.

More information on the profile area's key topics can be found here.

RWTH Aachen Profile Areas

RWTH Aachen University is convinced that in order to solve today's complex and multi-faceted problems, universities have to develop appropriate, integrated approaches. The Profile Areas are designed to address interdisciplinary topics and thus to enhance the University’s capability to engage in significant research activities and take on large-scale projects.
