About Bauphysik Feit
Bauphysik Feit GmbH is an engineering consultancy for building physics planning and consulting based in Klosterneuburg near Vienna. The service portfolio covers thermal building physics (thermal insulation, thermal bridge calculations, heat flow analyses, summer overheating protection), blower-door tests, energy performance certificates under EAVG/OIB and calculations of heating energy demand. A further focus is moisture protection with detailed design, condensation protection, water vapour diffusion calculations, moisture measurements and data logger evaluations. In the field of sound insulation, the consultancy offers building and room acoustics, including airborne and impact sound insulation verification, reverberation time assessment, structure-borne sound protection and room acoustic planning for event venues, cinemas and hotels. Building thermography is certified to DIN EN 473 (DIN 54162). Reference clients include Microsoft, ÖBB, the WKO Vienna, the Austria Center Vienna and the Federal Monuments Office; the consultancy has worked with architects such as David Chipperfield, Zaha Hadid, Coop Himmelb(l)au and Hans Hollein. The firm is run by Ing. Lukas Feit, the second generation of the family business.
