Result of certificate

The asset rating delivers an actual value for the primary energy demand that is even below the benchmark for new constructions. That is mainly due to the low primary energy factor of the district heat (0,6) and relatively high benchmark values. However, the asset rating gives the impression that the performance of the building is quite good.

The operational rating delivers a completely different picture. The energy consumption of the building is rated as medium looking at the slide ruler. The heating energy consumption is even slightly higher than the reference building.

Even considering that asset and operational rating references diferent kind of energies (primary or end energy respectively) they don't seem to be comparable. Further investigation will be done in the framework of Building EQ.
