Frequently Asked Questions


Is it mandatory to receive an Energy Identity Certificate?
As per the Regulation for Energy Efficiency in Buildings published in Official Gazette No. 27075 of 05.12.2008, existing buildings which were constructed or are still being constructed but had a building certificate before this regulation entered into force on 01.01.2011 are required to have an Energy Identity Certificate by 2017 and new buildings constructed after 2011 are required to have an Energy Identity Certificate at occupancy stage.
Which institutions Issue Energy Identity Certificates?
As per the Regulation for Energy Efficiency in Buildings and "Code of Energy Efficiency" No. 5627 published in 2007, existing buildings which had a building certificate before 2011 are required to obtain an Energy Identity Certificate until 2017. Energy Efficiency Consulting (EVD) companies authorized by the General Directorate of Renewable Energy issue Energy Identity Certificates for existing buildings. Betek Boya ve Kimya Sanayi A.Ş. is authorized by the Ministry of Energy and Natural Resources to issue Energy Identity Certificates for existing buildings.

For new buildings constructed after 2011, architects and engineers having authorization certificate to issue Energy Identity Certificates and Independent Consulting Engineer Certificates received from trade associations or legal entities which have architects and engineers vested with these qualifications issue Energy Identity Certificates. In new buildings, an Energy Identity Certificate is provided to relevant administrations when obtaining occupancy permit. According to the BEP regulation, new buildings which will be given an Energy Identity Certificate should at least have class C energy consumption and CO2 emission.
Under which conditions is an Energy Identity Certificate not necessary?
  • Buildings where production activities are carried out in the fields of industry,
  • Buildings whose intended use period is less than two years,
  • Buildings having a total use area less than 50 m2,
  • Green houses, Workshops,
  • Warehouses which were constructed separately and do not require cooling or heating as well as buildings such as storages, barns and sheepfolds,
  • Buildings with a total construction site of less than 1,000 m2 and which is out of the urban area.
  • Buildings of the Turkish Armed Forces, Ministry of Defence and subsidiaries, Secretariat of the National Intelligence Organisation.
What is the validity period of an Energy Identity Certificate?
And Energy Identity Certificate is valid for 10 years from date of issue.

However, in the case that an application (jacketing, thermal insulation, strengthening etc.) which changes the annual primary energy requirement of the building is performed, the Energy Identity Certificate will be renewed within 1 year in line with this regulation.
Why is it important that a building has a high energy class?
The Energy Class refers to annual energy consumption of the building. For instance, less energy is consumed for heating, cooling and ventilating a class A building compared to a building with energy class G. This affects purchasing-selling and renting prices of building and adds value to the building. It is also predicted that the government will attempt incentive activities (e.g. a new taxation system depending on Energy Class, etc.) in the coming years in order to raise the energy class of buildings in forthcoming years.
Is insulation mandatory for receiving an Energy Identity Certificate?
In our country, we consume 37.2% of the energy in buildings and 70% of the total energy consumed in buildings is used for heating. This situation shows that we consume 26% of the total energy in our country to heat buildings. Considering that we import 75% of our total energy and approximately 100% of our natural gas, this figures show the importance of energy efficiency in buildings.

Since the share of energy consumed in building is significantly high, it is essential to take measures such as thermal insulation to reduce the consumption and to certify these measures with an Energy Identity Certificate. With an Energy Identity Certificate received after thermal insulation is applied, owner or renter of the building or apartments within that building take advantage of 50% energy saving due to thermal insulation and purchasing-selling or renting value of the building or apartment increases.

An Energy Identity Certificate received before thermal insulation will only have an influence on realizing how high the energy consumption is. Since thermal insulation is an application which changes the primary energy requirement of the building, an Energy Identity Certificate received before thermal insulation will no longer be valid.
What are the parameters that affect the Energy Identity Certificate class of the building?
  • If the thickness of the insulation material to be applied on the building is appropriate to the standards of the region, the energy class of the building will be higher.
  • Windows with high insulation performance should be selected.
  • Economical lightening products should be chosen for much-used living spaces.
  • Alternative/renewable energy resources such as solar and wind energy should be utilised more.
  • Efficient combi boilers such as a condensing combi boiler should be used.
  • Automatic, programmable control devices can be used in central heating systems.
  • Using items such as white goods, televisions and split air conditioners in buildings, and the differences resulting from usage habits, will not affect the Energy Class of the building.
