BACS Requirements in Italy

Frequently asked questions

Common questions on the obbligo BACS, deadlines, incentives, and the APE in Italy.

Esiste in Italia un obbligo BACS (automazione degli edifici)?

Yes. EPBD Directive 2024/1275 Article 13 requires building automation and control systems in non-residential buildings (edifici non residenziali) whose HVAC systems exceed defined thresholds: above 290 kW since 31 December 2024, and above 70 kW from 31 December 2029. Italy transposes EU energy-performance directives mainly through Decreto Legislativo 192/2005 (as amended by D.Lgs. 48/2020) and the DM 26 giugno 2015 (Requisiti Minimi), and must align these with the 2024 EPBD recast. So the BACS obligation builds on an established Italian legal framework rather than appearing from nothing.

Quali edifici rientrano nella soglia dei 70 kW?

The threshold is the combined effective rated output of the building's heating, ventilation, air-conditioning, and combined systems. Any non-residential building over 70 kW is in scope from the end of 2029. This covers offices (uffici), retail and shopping centres (centri commerciali), hotels and tourism (alberghi), hospitals and care homes (ospedali, RSA), schools and universities (scuole, università), public-administration buildings, and industrial buildings with significant HVAC load. Italy's climate zones (A to F) mean the load mix varies by region — southern buildings often carry high cooling loads, northern buildings high heating loads — but both count toward the threshold.

Cosa si intende per BACS conforme?

A compliant system must reach at least Class C of EN ISO 52120-1 (formerly EN 15232), the standard that ranks automation from Class A (high performance) to Class D (non-efficient). Class C is the minimum, so Class D systems or buildings relying on simple timers and standalone thermostats are the primary upgrade targets. Functionally, the system must continuously monitor energy consumption, benchmark it against expected performance, detect faults and efficiency drift, give operators actionable information, and enable demand-based control of HVAC. A basic time-clock control does not qualify because it cannot monitor, report, or adapt.

Quali incentivi coprono l'automazione degli edifici (Conto Termico, Ecobonus)?

Italy has some of the EU's more generous incentive mechanisms. The Conto Termico 2.0, managed by GSE, can cover up to 65% of eligible costs for energy-efficiency interventions in public buildings and up to 40% for private buildings, including BACS installations. The Ecobonus provides tax deductions (historically around 50–65%) for energy-efficiency improvements in existing buildings, applicable to automation upgrades, and residual Superbonus measures may apply to comprehensive retrofits that include BACS. ENEA administers much of this and publishes technical guidance. Incentive rates and eligibility change with each finance law, so confirm the current conditions before budgeting.

What happens if a building misses the 2029 BACS deadline?

From the deadline, an in-scope building without a compliant system is non-compliant with Italian energy-performance law as it transposes EPBD Article 13. Enforcement runs through the existing regime around the APE (Attestato di Prestazione Energetica) and the inspection of heating and air-conditioning systems. Beyond the legal exposure, the practical costs are immediate: continued energy waste, a weaker APE class (which affects value and rental appeal), and missed Conto Termico / Ecobonus windows. Because automation projects take months to scope, fund, and commission, owners above 70 kW who wait until 2029 are likely to run late.
