Energy certification of buildings

Regulations for energy overviews for buildings and energy certification of buildings (NN 81/12, 29/13, 78/13), demands that a property owner (located in Croatia) is obliged upon sale or lease, to give the customer the insight of the energy certificate regarding the property in subject.

From July 1st, 2013, an energy certificate must be part of any contract of sale for real estate over 50 m2. From January  1st, 2016 it will be part of contracts concerning all real estates.

Our office is authorized to perform energy overviews and energy certificates, for buildings with simple and complex technical systems, in other words for all buildings. Authority number issued by the Ministry of Environmental Protection, Urban planning and construction is P-304/2013. We issue energy overviews and certificates for existing and new buildings for all regions in Croatia.
Energy overview (is done only for existing buildings as a prerequisite for certification and it consists of:

  • Beforehand preparations,
  • Data collection of information regarding the building
  • Implementation of control measurements if needed,
  • Analysis of energy and water consumption over the last three years
  • Proposed measures in order to improve energy performance of buildings that are economically justified also showing over what period of time the investment will be returned.
  • Reports and conclusions, with recommendations for future implementations that are economically justified in order to improve energy performance of a building.

Issuance of a energy certificate includes:

  • Review of existing project documentation,
  • Calculations regarding energy needs of a building,
  • Calculations of thermal energy for heating and cooling over a yearly base, for reference and actual climatic data,
  • Determination of the buildings energy class,
  • Development of an energy certificate,
  • Public display of the energy certificate.

Frequently Asked Questions

What is an energy certificate of a building and what’s the purpose?

The energy certificate is a document that presents the energy performance of the building in a written and graphical form assigned by regulations and is issued by an authorized person. The purpose of an energy certificate is to provide information to owners and users of real estate about energy performance of the building, the quality of the building outer core and the efficiency of their energy systems.

How much do energy certificates cost?

Our fees are created in accordance with the decision of maximum fees for conducting energy overviews and issuing energy certificates for buildings that can be followed in the wen pages of the Ministry.
If you wish to receive an official offer for energy certification, send a request.

What does an energy certificate for a building consist of?

An energy certificate contains general information of a building, information of the person that has issued the energy certificate, information of thermal technical systems, climate data, information regarding needed energy for reference and actual climate data, explanations of technical terms and applied regulations and standards.
Energy certification for existing buildings contains an economical proposal that justifies measures in order to improve energy performance of a building that are based on a previously conducted overview of a building.

When does an energy certificate expire?

The validity of an energy certificate is 10 years.

What buildings must have an energy certificate?

Every building or individual unit that is being built, sold, rented or leased must have an energy certificate.

Can an energy certificate be issued for only one apartment in a building?

An energy certificate can be issued for only an individual unit (apartment, office, etc.)
In case that the entire building already has an energy certificate, then the certificate issued for the individual unit is valid.

Until when should an energy certificate be developed for an existing building?

Existing building or their individual units (apartment, office, etc.) that are for sale, must have a valid energy certificate, available to be viewed by the customer before entering into a contract of sale, from July 1st 2013. An energy certificate is an integrated part of the sale contract.
When a property is being advertised, the energy class must be notified for the whole build or the individual unit.
Existing buildings or their individual units (apartment, office, etc.) that are for rent, leased, must have a valid energy certificate that is to be shown to the tenant or lessee, prior to entering into a contract of rent or lease, starting from January 1st 2016.

Who can issue an energy certificate for a building?

An energy certificate can be issued only by an authorized subject.
Authorization for conducting energy overviews and issuing a energy certificate is issued by the Ministry in charge of construction.

What is necessary in order to create an energy certificate for an existing building?

To create an energy certificate of an existing building, an authorized person must conduct an energy overview of the building. The investor or property owner must allow the authorized person to conduct an energy overview and to insure data, technical documentation of the building and other necessary documentation, and in particular:

  • data of the consumption of all forms of energy and water of the building prior to the last three years (accounts of the supplier or otherwise)
  • technical documentation of the building and technical documentation of equipment installed in the system that are subject of inspection (architectural design, mechanical plans, electrical plans, etc.)
