Team X4S

At Biberach University of Applied Sciences, Energy – and Civil-Engineers, Project Managers and Architects have formed a strong interdisciplinary team. Together we will work as Team X4S – Extension for Sustainability to achieve the project demands. Not only students and professors from all fields are working together but also researchers from various institutions collaborate on the ambitious and interdisciplinary project and share their specialist expertise.

Our team coordination and project management is conducted by Master student Lena Frühschütz and Prof. Andreas Gerber, both from the institute of Energy Engineering.
