Energy class in Germany (Energieausweis)
Official certificate: Energieausweis
Germany 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+ | ≤ 30 |
| A | ≤ 50 |
| B | ≤ 75 |
| C | ≤ 100 |
| D | ≤ 130 |
| E | ≤ 160 |
| F | ≤ 200 |
| G | ≤ 250 |
| H | > 250 |
How the estimate works in Germany
In Germany, 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 1,400 local climate zones in Germany.
