What is the Energy Performance Certificate (EPC) and How to Get It?

The Importance of Energy Performance in Turnkey Projects in Antalya

Today, energy efficiency and environmental sustainability are among the top priorities in the construction sector. In this context, the Energy Performance Certificate (EKB) — a mandatory document for obtaining a building occupancy permit (iskan) — serves both as a legal requirement and as a long-term investment in property value. This comprehensive guide answers all your questions about the EKB, with a specific focus on Antalya.

1. What is the Energy Performance Certificate (EKB)?

The Energy Performance Certificate is an official document that indicates the energy efficiency of a building. It evaluates several key parameters such as:

• Annual energy consumption

• Heating and cooling systems

• Insulation quality

• Lighting systems

Based on these factors, the building is assigned an energy class from A to G.

The primary goals of the EKB are to:

• Increase energy efficiency

• Reduce greenhouse gas emissions

• Help consumers make informed decisions

2. Why is EKB Mandatory in Antalya?

In warm and humid climates like Antalya, building energy efficiency directly impacts living comfort. Therefore, the EKB is not only a legal obligation but also a practical necessity.

Buildings that require an EKB include:

• All buildings with permits issued after 2011

• Public and commercial buildings over 1,000 m²

• Buildings undergoing renovation that affects energy systems

To obtain an occupancy permit in Antalya, the energy performance certification process must be handled professionally. This process is often integrated with the structural (static) and mechanical design phases.

3. Connection Between EKB and Structural Design in Antalya

A building's static project defines its load-bearing system, but aspects like:

• Orientation

• Material selection

• Façade openings

• Thermal bridges

have a direct impact on energy performance. In Antalya, these structural details are crucial inputs in the EKB simulation. Parameters such as insulation thickness, window-to-wall ratios, and shading elements affect the building's energy class.

4. The EKB Process in Turnkey Projects

In turnkey construction, EKB responsibilities fall on the construction company. The process includes:

• Project Design Stage: Coordinated planning with architectural, structural, and MEP (mechanical, electrical, plumbing) designs

• Energy Expert Assignment: Certified EKB consultants or engineering offices in Antalya are appointed

• BEPTB Entry: Building data is input into the national BEP-TR software for energy simulation

• Certificate Preparation: The document is finalized and submitted to the municipality

Many turnkey contractors in Antalya deliver EKBs along with other official documentation to clients.

5. What is Energy Class and How Can It Be Improved?

The EKB assigns an energy class (A-G) based on:

• Insulation quality

• Window specifications and heat transmittance

• Efficiency of heating/cooling systems

• Use of renewable energy sources

• Lighting systems (LED, motion sensors, etc.)

Tips to improve your energy class in Antalya:

• Use adequate thermal insulation

• Install high-performance PVC windows

• Integrate solar energy systems

• Select efficient HVAC and water heating systems

6. How Is the EKB Prepared?

The certificate preparation involves several stages:

• Architectural Analysis: Floor plans, orientation, window areas are reviewed

• Material Inputs: Wall, roof, floor, and window materials are entered with U-values

• Mechanical Systems: HVAC and ventilation systems are assessed

• Software Simulation: Energy modeling is conducted via BEP-TR 2 software

• Approval and Submission: The document is printed and submitted to local authorities

7. Working with Authorized Companies in Antalya

Firms authorized to issue EKBs must be accredited by the Ministry of Environment, Urbanization, and Climate Change.

In Antalya, such companies provide:

• EKB preparation for new buildings

• Energy analysis for existing structures

• Pre- and post-insulation efficiency comparisons

• Official documentation and municipality follow-up

Partnering with a qualified EKB provider ensures a smooth and compliant process.

8. Can Existing Buildings Get an EKB?

Yes. For any building to be sold or rented, it must have an EKB — even if it was built before 2011. These are categorized as "existing building" certificates and may receive lower ratings.

Steps include:

• Site inspection and data collection

• Thermal insulation analysis

• Review of HVAC systems

• Energy simulation

⚠️ Note: Certificates issued without insulation upgrades may fall into lower energy classes.

9. Validity of the Energy Performance Certificate

An EKB is valid for 10 years. However, updates are necessary if the building undergoes:

• Insulation upgrades

• HVAC system changes

• Floor or façade extensions

• Solar system integration

Given the climate variability in Antalya, it's advisable to review the certificate every 5-6 years.

10. Can You Sell or Rent Without an EKB?

No. As of 2020, buildings without an EKB cannot be legally sold or rented. This makes the certificate crucial in Antalya’s real estate market.

The property owner is responsible for:

• Providing the EKB to the buyer or tenant

• Displaying the energy class in listings

11. Real Estate Projects in Antalya with EKB

New projects in Antalya — especially in Lara, Konyaaltı, and Döşemealtı — are often delivered with A or B class certificates, offering:

• Lower utility bills

• Higher indoor comfort

• Increased property value

• Better marketability

12. Frequently Asked Questions (FAQ)

Q: Is the EKB mandatory?
A: Yes, for buildings with permits issued after 2011.

Q: How long does it take to get an EKB?
A: On average 3–5 business days if the designs are ready.

Q: Can insulation upgrades improve the rating?
A: Yes, effective insulation can raise the energy class.

13. Conclusion: Legal and Efficient Buildings Start with EKB

The Energy Performance Certificate is essential for every building constructed, sold, or rented in Antalya. Whether you're a homeowner or a developer, the EKB ensures legal compliance and long-term energy efficiency.
