A brand new window with thin-layer glazing combines energy efficiency with the aesthetics of a baroque window.

Restoring historic buildings and saving energy at the same time is now a reality. Passive house window expert Franz Freundorfer developed the heat-saver for the Waaghaus in Bolzano, a building from the 13th century. Combining and old traditions the scientists want to bridge the gap between the conservation of historic buildings and improving .

Also, the Palazzina della Viola, built in Bologna in 1497, was given a make-over. Preserving delicate original material had limited the , but even though the heating and cooling loads were reduced by 12% and 30% respectively. The indoor climate conditions were improved for achieving comfort and artwork-preserving conditions. Today,the building is the headquarters of the University´s Department of International Exchange, serving seven thousand students every year.

Passive house window expert Franz Freundorfer developed the heat-saver together with researchers and experts of the 3encult project for the Waaghaus in Bolzano, a building from the 13th century.
