Resale File Preservation — Energy performance certificate
Primary official evidence
Preserve a file that can be handed to the next buyer: reference record, verification results, corrections, supporting documents and last-check date. A strong file shortens future due diligence and avoids rebuilding the property history from scratch. An EKB is a regulatory energy-performance document, not a guarantee of the utility bill for one unit. Verify certificate number, address, block, building type and class against the property being reviewed. The Ministry updated the Binalarda Enerji Performansı Yönetmeliği in June 2025 with newer efficiency criteria and expansion of near-zero-energy requirements, so review the certificate date and the regulatory regime under which it was issued. Preserve the final evidence and resolution history that explains the decision, but refresh facts that can change when a later resale review begins.
Key verification points
An EKB is a regulatory energy-performance document, not a guarantee of the utility bill for one unit.

Timing and change risk
Start by reconciling “Use the certificate as an input for comparing likely operating performance across similar alternatives, not as a guarantee of a future bill.” with “An energy-performance certificate should be read together with the building’s registered legal and technical status; material system changes may require a project and permit amendment depending on the case.”, then use “Before signing a contract or amendment that changes rights or obligations.” as an independent cross-check if they conflict. The evidence must relate to the same property and transaction period.
Decision standard
