About us

The Chair of Circular Engineering for Architecture (CEA) conducts research to adapt reused architectural materials and projects for the circular economy through digitization. Construction projects are often complex, multi-variant problems that are handled by numerous parties in separate silos. The construction industry can learn from other industries when it comes to adopting digital technologies and circular strategies. Automating the reuse of materials in architecture can bridge this gap by connecting stakeholders across the value chain.
