Lamia Messari-Becker

Prof. Dr.-Ing. Lamia Messari-Becker (born 1973, married, two children)took over the professorship for energy-efficient building technology at KIT, the Karlsruhe Institute of Technology, in April 2025. Prior, she had been Professor of Building Technology and Building Physics at the University of Siegen since 2013.

Prof. Messari-Becker is a policy advisor, including a former member of the German Government’s Expert Council on the Environment (2016-20), a member of the Federal Ministry of Building’s Expert Group on Future Construction (since 2017), a member of the Convention of the Federal Foundation for Building Culture, and a member of the renowned Club of Rome (since 2020).

Lamia Messari-Becker: “The energy transition and sustainable building: Heat pumps are one option. Other options would be there if you only wanted them. I have always said: wind and photovoltaics must be joined by other renewable energy sources – biomass, biogas, geothermal energy and waste heat. We need a real heat turnaround.”

Prof. Messari-Becker is an alumna of the U.S. government’s International Visitor Program. For years, she has played a key role in shaping the sustainability debate in the building industry.
