Energy class in Austria (Energieausweis)

Official certificate: Energieausweis

Austria uses the Energieausweis certificate to classify the energy performance of buildings.

The scale is absolute: thresholds are expressed in kWh/m²·yr.

Official Energieausweis scale

Class Max energy (kWh/m²·yr)
A++ ≤ 10
A+ ≤ 15
A ≤ 25
B ≤ 50
C ≤ 100
D ≤ 150
E ≤ 200
F ≤ 250
G > 250

How the estimate works in Austria

In Austria, the Energieausweis class is based on absolute primary energy consumption (kWh/m²·yr). EnergyClass calculates the building's estimated energy need and compares it to official thresholds to assign the class.

Data available for 1,035 local climate zones in Austria.
