Building Systems Technology, Department Energy Efficient Buildings

Research focus

  • Concepts for energy efficient buildings
  • Application of renewable energy in buildings
  • Building stock analysis (size and development, energetic performance, installed H/C-technologies)
  • Modelling/simulation and analysis of building energy demand
  • Evaluation of energy systems (focus building-grid interaction, sector-coupling)
  • Renewable energy and energy efficiency technology development assessments

Curriculum vitae

Benjamin Köhler was born in 1986 and studied industrial engineering with a focus on energy and environmental management at the University of Applied Sciences in Flensburg and the Hogeschool voor Economische Studies (HES), Amsterdam. Since 2012 he is working as a researcher and project manager at Fraunhofer ISE. His current work is focused on the analysis of energy efficiency measures in residential and non-residential building stocks as well as the simulation of heating and cooling demands buildings/ building stocks. Concerning energy efficiency the focus is on thermal insulation and energy efficient supply technologies, for which he analysed technical and economic development potentials until 2050. He contributed to the BMWi initiative "Grid-Interactive Buildings", the project "Carbon Neutral Buildings in 2050" and the ISE study "100 % Renewable Energy for Electricity and Heating in Germany”.
