Department III
Department III – Building Physics, Technical Building Equipment
Department III covers the entire spectrum of building physics – from structural and system-based fire protection to thermal and sound insulation – and the multifaceted field of building services. Seven sections address the regulatory concerns in this area using their wealth of expertise.
In addition, Department III coordinates the granting of project-related approvals (ZiE) and project-related construction technique permits (vBG) for the state of Berlin.
