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 1917: technical utility systems require periodic updating and capital maintenance.
Estimated energy class E: typically higher heating demand than modern A/B developments. No official certificate on record; the class is inferred from the construction year. Check the actual class and heating costs against the certificate and real bills.
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.
