CV
Prof Rüdiger Lorenz studied physics at RWTH Aachen and has been Professor of Building Physics and Building Climatology at the University of Applied Sciences Potsdam since 2004. He teaches in the Departments of Civil Engineering and Architecture as well as in the Restoration programme at the University of Applied Sciences Potsdam and is head of the associated building physics laboratory. For 8 semesters, he was also a guest lecturer in the international Master's programme Integrated Architectural Design/International Facade Design and Construction at the Ostwestfalen-Lippe University of Applied Sciences and works as a consultant.
From 2016 to 2022, he was also active as Vice President for Special Tasks – campus development. In this role, he advocated for the long-term functional development of the campus in terms of resources and sustainability in new construction and renovation projects at the University of Applied Sciences Potsdam.
He has many years of experience in property consultancy for new buildings and refurbishment projects on building physics, building climate control and façade technology. After a research project on building simulation at the University of Siegen, he switched to commercial consulting in 1994. He worked in three different engineering offices in Ratingen, Cologne and Berlin until 2011. He completed his 12-year tenure as head of the Building Physics and Building Climatology working group at Prof. Michael Lange GmbH with, among other things, the design and building physics/building climate development of the Schild Hybrid façade for the new ECB high-rise building in Frankfurt.
As a scientific member of the Climate Protection Council of the City of Potsdam, headed by Mayor Jann Jakobs, he campaigned from 2008 to 2018 for a resource- and climate-friendly development of Potsdam and contributed to the Potsdam Masterplan "100% Climate Protection by 2050". He continues his efforts to promote forward-looking urban development in organisations such as Energie Forum Potsdam e.V.

Award
Brandenburg State Teaching Award 2021 "Digitale Lehr- und Lernszenarien – die Chance in der Krise nutzen"
https://mwfk.brandenburg.de/mwfk/de/wissenschaft/landeslehrpreis/#
with the contribution "Labor Bauphysik":
Basic teaching, lecture components and practical exercises in the building physics laboratory were replaced by instructional videos with discussion rounds and a virtual laboratory environment. A repurposed whiteboard tool (MIRO) simulated the real laboratory situation by positioning graphic images of prepared device components in a plan display and connecting them logically instead of handling the devices manually.
In order to convey device handling and the assembly process more dynamically, static camera systems were used as well as camera systems carried "on the man". https://youtu.be/LPfAy-oebDE
