Felix Wellnitz

Prof. Dr.-Ing. Felix Wellnitz is a Professor of Building Physics at Berlin University of Technology's Department of Architecture and Building Technology. His academic career includes previous positions as Professor for Indoor Climate and Building Renovation at OTH Regensburg (2014-2018) and teaching assignments at GUC Berlin and FH Potsdam. He serves as a freelance architect and certified expert for thermal/moisture protection with specialized expertise in energy consulting for listed buildings.

Education:

• Ph.D. in Engineering, Bauhaus University Weimar (2014)
• M.Sc. in Building Protection, University of Wismar (2012)
• Diploma in Architecture, TU Darmstadt (2004)

Wellnitz's research focuses on sustainable preservation of architectural heritage, building physics innovations, and energy-efficient retrofitting. His work bridges historical preservation with contemporary climate challenges, particularly through advanced materials like aerogel-based insulation systems. Key research themes include:

• Climate-responsive restoration of modernist landmarks
• Building diagnostics and monitoring in cultural heritage
• Thermal performance optimization in historic structures
• Integration of renewable energy in sensitive contexts

His publications demonstrate consistent focus on reconciling monument preservation with energy efficiency requirements. Recent work emphasizes practical applications of building physics principles in World Heritage sites, climate adaptation strategies for postwar modernism, and policy frameworks for sustainable renovation.

Research Projects:

• High-performance insulation in Bruno Taut's Waldsiedlung Zehlendorf (World Heritage application support)
• Sustainable renovation of Hans Scharoun's Haus Schminke (€67,000 grant)
• Climate optimization of Asam Church in Weltenburg (€40,000 grant)
• Energy modernization of Margaretenau residential district (€3.45 million BMWi grant)

He leads the Building Physics laboratory at BHT and collaborates with institutions including the Haus Schminke Foundation and Benedictine Abbey of Weltenburg. Professional memberships include the Berlin Chamber of Architects, WTA Scientific-Technical Working Group for Building Preservation, and Sep-Ruf-Society.
