The Flemish region continues its commitment to carbon neutrality with enhanced energy requirements for non-residential buildings. From 2025, energy performance certification for non-residential buildings (PEB NR or kNR) will become mandatory for all large units with a floor area of at least 1,000 m². Here are the main deadlines and requirements to bear in mind.
Objective of PEB NR certification
PEB NR certification is designed to inform potential owners, buyers and tenants about a building's energy performance. It also serves to encourage owners to improve the energy efficiency of their properties, thereby aligning the building stock with long-term sustainability and carbon reduction objectives. A minimum energy label must be achieved after a period of five years following the sale or letting of a property.
Chronology of Obligations
Since 2023: PEB NR is mandatory for non-residential units when they are sold (including transfers via surface rights or emphyteusis) or when new rental contracts are concluded.
2025: As of January 1, 2025, all large non-residential units with a floor area of 1,000 m² or more must have a valid PEB NR certificate.
2026: From January 1, 2026, this obligation will extend to medium-sized non-residential buildings, i.e. those with a floor area of less than 1,000 m².
2028: All large public and government buildings will have to comply with a PEB NR label rated at least “E”. Since 2024, these structures have already been required to hold a PEB NR, replacing the former PEB Public certificate.
2030: From January 1, 2030, all non-residential buildings, regardless of size, will have to present a valid PEB NR certificate with a minimum label of “E”.
Implications for owners and real estate players
These new obligations mark an important step towards the energy transition in Flanders. However, they also pose logistical and financial challenges for property owners, who will often have to undertake renovation work to improve the energy performance of their buildings.
For real estate companies and investors, anticipating these deadlines is essential. It is advisable to carry out energy audits beforehand, and to plan improvement work to comply with the standards while optimizing costs.
Conclusion
The growing energy performance requirements in Flanders reflect a clear desire to accelerate the sustainability of the non-residential building stock. For owners and professionals in the sector, complying with these regulations represents an opportunity to contribute to a greener future, while increasing the value of their real estate assets.
