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 1900: 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.

Sale prices — notarised apartment sales, Maa- ja Ruumiamet; estimates — the Estiq AVM model; rents — Estiq market database (24 months); wages — Statistics Estonia (PA117); building data — building register (EHR); association costs — housing associations' annual reports; noise and air — national noise maps and air monitoring. Figures refresh with every data load and each states its period and sample — see the methodology.

Building data reconciled against the EHR and Land Board (Maa-amet) registries. AVM methodology by Martin Koppel, Estiq real estate valuation advisor (methodology aligned with the EVS 875 standard). This is an automated model estimate, not an EVS 875 appraisal report. Updated 19.10.2026.
