Building Energy Rating Guide

The energy performance certificate reflects the heating efficiency and energy consumption intensity of the building.

E · this building Higher Energy Demand Noticeable heat loss; typical of older housing stock

Key Risk Factors

  • Built in 1954: technical utility systems require periodic updating and capital maintenance.
  • Energy class E: typically higher heating demand than modern A/B developments. The energy certificate has expired, so the current class may differ. Actual heating costs depend on the apartment and how it is used.
  • Parking: on-grade surface parking on parcel/street; no separate underground garage.
  • Valuation nuance: bank collateral value for a specific unit depends fundamentally on interior finish.
