Proof and digital verification solutions
The Spanish Certificados de Ahorro Energético (CAE) system is based on forgery-proof digital evidence, in particular certified time-stamped photos. With a regulatory framework that facilitates the traceability of installations and simplifies the burden of proof for each standardized sheet.
Real Decreto-ley 18/2022 requires that all CAE applications be accompanied by photographic evidence validated by a qualified time stamp(sello de tiempo calificado), guaranteeing:
✔️ Authenticity of work carried out (prevents fraud).
✔️ Integrity of proof (impossible to modify after registration).
✔️ Full traceability thanks to eIDAS-compliant time stamping, registered in the Registro de Certificados de Ahorro Energético (RCAE).
The legal basis for this requirement is Article 10 of Real Decreto-ley 18/2022(Prueba documental de la medida de eficiencia energética) , which is based on EU Regulation 910/2014 (eIDAS) on electronic evidence.

Qualified time stamping(sello de tiempo calificado) is based on three key elements:
🔹 An electronic time-stamp certified by a qualified eIDAS provider(Prestador de Servicios de Confianza Cualificado).
🔹 A secure time-stamped record containing the file’s metadata.
🔹 Validation by an energy certification authority before the CAE is issued.
