Binalarda Enerji Performansı Yönetmeliği (Regulation on Energy Performance of Buildings)

Overview

The Regulation on Energy Performance of Buildings is published by the Turkish Ministry of Environment, Urbanisation and Climate Change, in a consolidated text with the 2025-2026 amendments. Its basic rule is that a building permit is not issued if the architectural, mechanical and electrical projects do not meet the regulation's energy-economy requirements (Article 5(2)). Energy performance is thus checked at design stage as a permit condition.

The regulation defines the Energy Identity Certificate (EKB). The EKB is calculated with the Ministry's method and is valid for 10 years from issue (Article 25). It contains annual energy for heating, cooling, ventilation and hot water (kWh/yr) and primary energy by energy type (Article 26(1)). It is the main instrument for documenting building-services energy.

The nearly-zero-energy building provision requires buildings of 2,000 m2 total construction area and above to be built as NSEB, with a BEP-TR pre-calculation form submitted together with the permit drawings (Article 23(2)). NSEB buildings must reach energy class B or better and cover at least 10 percent of primary energy demand with on-site renewables (Article 23(1)).

The limit of the document is that the calculation focuses on building services (heating, cooling, ventilation, hot water); nothing in the record covers the IT process load of data centres. Related documents named are Energy Efficiency Law No. 5627, EN ISO 52000-1 and ISO/IEC 30134-3. In data centre projects the 2,000 m2 threshold and the NSEB requirement should be checked early.

Key points

1. A building permit is not issued if architectural, mechanical and electrical projects do not meet the energy-economy requirements (Article 5(2)).
2. Buildings of 2,000 m2 total construction area and above must be built as NSEB, with a BEP-TR pre-calculation form submitted with the permit drawings (Article 23(2)).
3. NSEB buildings must reach energy class B or better and cover at least 10 percent of primary energy demand with on-site renewables (Article 23(1)).
4. The EKB is calculated with the Ministry's method and is valid for 10 years from issue (Article 25).
5. The EKB includes annual energy for heating, cooling, ventilation and hot water (kWh/yr) and primary energy per energy type (Article 26(1)).
6. The text is consolidated with the 2025-2026 amendments.

Using it in design

• In the building/sustainability module (TR profile), add an NSEB check for buildings of 2,000 m2 and above: target class B and at least 10 percent of primary energy from on-site renewables.
• Estimate the PV area needed.
• Keep the IT process load separate from building services in the BEP-TR-style calculation.
• Provide an output that adds the BEP-TR pre-calculation form to the permit file.

Who should read it

Architects and mechanical-electrical engineers designing data centre buildings in Turkey, and consultants managing the permit process.
