¹ U value (Heat transfer coefficient) calculated according to ÖNORM EN ISO 6946. A++: U-Werte im Bereich der Markierung A++ (0,13 W/m²K) sind notwendig, um derartige Gebäude zu errichten. RL6: OIB Richtlinie 6 (April 2007); In ganz Österreich seit 1.1.08 verbindlich festgelegter max. U-Wert (0,35 W/m²K) für alle Neubauten sowie instandgesetzte bzw. erneuerte Bauteile.
² For the OI class, the U-value of the component is taken into account in addition to the ecological key figures
