Mandatory Energy Audit for Heating and/or Cooling Systems Over 70 kW
If your organisation operates a heating and/or cooling system with a capacity exceeding 70 kW, commissioned before 1 January 2022, it is important to note that the deadline for the mandatory energy audit is 31 December 2025. The audit is required under the provisions of Government Decree No. 666/2020 (XII.28.).
Who Is Affected by This Obligation?
The regulation applies to all organisations and institutions with buildings that operate heating or cooling systems above 70 kW, including:
- Companies and industrial operators
- Housing associations and property manager
- Municipalities and public institutions
- Any other operators of building energy systems
Purpose of the Audit
The energy audit aims to provide a reliable overview of the energy efficiency of the relevant equipment and systems. Its goal is to support the optimisation of energy consumption and operational costs.
When Must the Audit Be Carried Out?
The exact obligations depend on the date the system was commissioned and the type of operator:
| System type | Deadline |
|---|---|
| 2022. Systems commissioned before 1 January 2022 | 2025. By 31 December 2025 |
| New systems | Within 1 year of commissioning |
| Repeat audit of existing systems | Every 8 years, or every 4 years for large enterprises |
Key Information
- The audit requirement applies to all heating and cooling systems above 70 kW.
- Systems are affected if they serve building heating or cooling purposes, even partially.
- Heat generators used solely for technological purposes are exempt from the obligation.
- The audit must be conducted exclusively by a certified expert registered by the National Climate Protection Authority.
- Results must be recorded in the Climate Gas Database.
- Even in cases of exemption, the system must still be reported — this remains a legal obligation.
- Failure to comply may result in regulatory fines.
Legal Framework
The mandatory energy audit is prescribed by the following legislation:
- 2015. Act LVII of 2015 on Energy Efficiency in particular Chapter VIII/A, Section 25/A
