Change Control — Energy performance certificate
Primary official evidence
If registry, project, numbering or share data changes after verification begins, preserve the old and new versions with date and reason. A valid change may be legitimate; relying on a superseded version is the real risk. 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 old and new material versions with the date and reason for change, then reassess every conclusion affected by that change.
