Summary

Italy’s Legislative Decree 192/2005 establishes the national framework for building energy performance. It sets minimum energy standards for new buildings and major renovations and requires an Energy Performance Certificate (EPC) for regulated transactions such as sales and rentals. Owners, landlords, and developers must ensure compliance, keep documentation, and follow HVAC efficiency and inspection rules where applicable. Non-compliance can lead to administrative fines and permitting or transaction-related consequences. The decree remains a cornerstone of Italy’s building decarbonisation pathway.

What’s Required

Legislative Decree 192/2005 is Italy’s core framework for building energy performance. It sets minimum energy-performance requirements for buildings and introduces the system of energy certification used for sales, rentals, and major renovations.

In-scope parties (owners, landlords, developers, designers) typically must:

  • Ensure buildings meet minimum performance requirements for new builds and major renovations.

  • Obtain and provide an Energy Performance Certificate (EPC) for property transactions (sale/rent) and in other regulated cases.

  • Comply with rules for HVAC system efficiency and related inspections where applicable.

Important Deadlines

  • Ongoing obligation tied to building permits, major renovations, and transactions (sale/rental).

  • Periodic updates occur through secondary decree,s aligning thresholds and calculation methods with EU revisions.

Current Status

In force and continuously updated through implementing decrees. It remains the backbone of Italian building energy policy and is increasingly connected to renovation incentives and decarbonisation measures.

Penalties for Non-Compliance

  • Administrative fines for missing/incorrect APE documentation.

  • Sanctions for non-compliant works where the minimum requirements are not met.

  • Potential invalidity risks or enforcement actions in transactions, depending on the breach type.

Examples of Known Violations

Common enforcement issues include missing APEs in rental listings or sales, incorrect certificates, and non-compliant renovation documentation.
