Building Energy Rating Guide

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

A Nearly Zero Energy Building Extremely low energy demand
B Low Energy Building Very high thermal performance
C Energy Efficient Good standard efficiency
D Average / Refurbished Moderate heating expenses
E · this building Higher Energy Demand Noticeable heat loss; typical of older housing stock
F–G High / Very High Consumption Requires substantial energy efficiency renovation

Key Risk Factors

  • Built in 1988: technical utility systems require periodic updating and capital maintenance.
  • Estimated energy class E: expected winter heating expenses are higher than modern A/B developments.
  • 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.

Does the Estiq online valuation replace a bank-certified appraisal?

No. Estiq AVM is a data-driven statistical benchmark. Mortgage financing applications require a certified appraisal report performed by a licensed appraiser in accordance with EVS 875 standards.

The Estiq AVM reports a confidence band by comparable-transaction volume: ±5–8% where comparables are plentiful, ±10–14% with moderate data, ±18–25% where data is sparse. Accuracy is higher in active areas and lower for atypical properties. It is a statistical benchmark, not an EVS 875 report. See the methodology page.
