Renovation of Haus am Schottentor in Austria

The roof of this listed building had been renovated multiple times in the past. The roof was originally built to be highly vapour-proof, as was the standard at the time. Solving the construction physics requirements was the job of Buschina & Partner Ziviltechniker GmbH. The particular challenge lay in the fact that

• the outer shell of the building cannot be altered
• a solution that worked from a construction physics perspective had to be found for the attic conversion with interior thermal insulation
