About TAS Bauphysik
TAS Bauphysik GmbH is an engineering consultancy based in Leonding near Linz that offers building physics planning services and measurements in the specialist fields of thermal, moisture and acoustics. Its service portfolio includes energy performance certificates, two-dimensional and three-dimensional heat flow analyses for thermal bridge assessment, thermodynamic building simulations, airflow simulations (CFD), daylight simulations, water vapour diffusion calculations and hygrothermal simulation calculations using WUFI®. In the field of acoustics, the company designs noise control measures for industrial and commercial installations, performs three-dimensional sound propagation calculations and plans the building and room acoustics of buildings. Together with the Bautechnisches Institut Puchenau (BTI), TAS Bauphysik operates an accredited sound test laboratory for standard-compliant sound transmission measurements on wall and ceiling components, doors, windows, glazing assemblies and residential ventilation units. The company's roots go back to 1984/85; since 2001 it has traded as TAS Bauphysik GmbH.
