BACS Requirements in Poland

Article 13 of Directive (EU) 2024/1275 mandates BACS in non-residential buildings where technically and economically feasible.

In Poland, energy performance is governed by the Ustawa o charakterystyce energetycznej budynków (Act on Energy Performance of Buildings) and supporting regulations from the Ministry of Development and Technology. The świadectwo charakterystyki energetycznej (energy performance certificate) system is the primary compliance mechanism.

The technical standard is EN ISO 52120-1 (formerly EN 15232). Class C is the minimum acceptable BACS level.

Reaching EN ISO 52120-1 Class C is not about installing a single control panel — it is about what the system can demonstrably do. A compliant building automation and control system in Poland must be able to continuously monitor energy use, benchmark that consumption against expected performance, detect faults and efficiency drift, give facility teams actionable information, and adjust HVAC operation to actual demand rather than fixed schedules.

Many Polish commercial buildings constructed during the rapid 2000s–2020s expansion have a basic building management system (system zarządzania budynkiem), but a BMS label alone does not guarantee Class C capability. Time-clock heating control and standalone thermostats do not meet the standard. The practical question for owners is whether their existing controls can monitor, report, and optimise — or whether they only switch equipment on and off.

• Ustawa o charakterystyce energetycznej budynków is the primary transposing legislation. Amendments for the 2024 EPBD recast are in preparation.
• NFOŚiGW (National Fund for Environmental Protection) administers programs like Czyste Powietrze and energy efficiency grants for commercial buildings.
• BGK (Bank Gospodarstwa Krajowego) offers preferential financing for energy efficiency investments including building automation.
• Large commercial building stock — Poland has significant office, retail, and logistics space built in the 2000s–2020s that may lack adequate BACS.
• EU Cohesion Funds remain a major source of co-financing for energy efficiency upgrades in Polish commercial buildings.

Because transposition of the 2024 recast is still in progress, the exact enforcement mechanism and any national deviations should be confirmed against the Ministry of Development and Technology before making investment decisions. The directive's 70 kW deadline of 31 December 2029 is the planning anchor, but Polish secondary legislation may add detail on inspection and reporting once finalised. Building owners who act early can sequence the upgrade alongside other planned refurbishment and make the strongest case for co-financing.
