About Bayer Bauphysik
Bayer Bauphysik Ingenieurgesellschaft mbH is an engineering consultancy based in Fellbach near Stuttgart, founded in 1998 by Dipl.-Ing. Christoph Bayer. The firm offers the full spectrum of building physics services: thermal building physics with thermal insulation verification under EnEV, 2D and 3D thermal bridge calculations, verification of summer thermal performance according to DIN 4108-2, as well as thermal dynamic building simulations. Further areas include building and room acoustics with sound insulation verification according to DIN 4109, vibration decoupling, noise forecasts for traffic, commerce and leisure, and daylight simulations as part of DGNB certifications. The offering is complemented by measurement-based investigations such as blower-door measurements according to DIN EN 13829, U-value, moisture, airborne sound and reverberation time measurements, as well as ventilation concepts and consulting on building waterproofing. Reference projects include administrative buildings, residential developments, hotels, schools, hospitals, swimming pools, sports and cultural buildings, and research buildings, including the Federal Constitutional Court in Karlsruhe, the Mercedes-Benz Museum and Max Planck Institutes. From Fellbach, projects are handled throughout Germany and also internationally.
