What’s Required

This decree transposes the EU Energy Efficiency Directive. It requires large enterprises and energy-intensive companies to perform energy audits every four years, covering buildings, industrial processes and transport.

Alternatively, companies may comply by implementing and certifying an ISO 50001 energy management system.

Audits must identify energy-saving opportunities, quantify consumption and document improvement measures.

Important Deadlines

  • First audit required by December 2015.

  • Recurring audits every four years (2019, 2023, 2027, etc.).

  • Continuous compliance for companies newly reaching “large enterprise” thresholds.

Current Status

  • Fully in force and tightly enforced by Italy’s energy agency (ENEA).

  • Integration with the revised EU directive will expand the scope and tighten audit requirements.

Penalties for Non-Compliance

  • Substantial administrative fines for missing audits or non-submission.

  • Fines apply per site or per missing audit cycle.

  • Repeated non-compliance can trigger enhanced supervision.

Examples of Known Violations

ENEA regularly reports companies fined for failing to meet audit deadlines or submitting incomplete reports. Violations mostly affect industrial firms with complex facilities.
