2010 Energy Performance of Buildings Directive

All new buildings, for which a location permit or a building permit is issued after 31st December 2019, must adhere to the nZEB (nearly zero energy building) standard.
All new buildings used by public authorities, for which a location permit or a building permit is issued after 31st December 2017, must adhere to the nZEB standard.
If a public building is undergoing an energy renovation, it is possible to use the measure 'ESIF Energy Efficiency in Public Sector Buildings’, a Croatian Bank for Reconstruction and Development (HBOR) loan instrument to facilitate the completion of funding plans for energy renovation projects of public buildings which have already received funding, but are not fully funded yet.

All private citizens, legal entities, and public authorities which own new buildings.

In order to verify that a new building is going to satisfy the nZEB standard, the main project (in part relating to rational energy use and thermal protection) must reflect this standard as laid out in the Technical regulation on energy economy and heat retention in buildings. Furthermore, a document called the Building’s energy performance register must be attached to the main project. The main project and the Building’s energy performance register are mandatory attachments to a building permit application.
In order to obtain the usage permit for a new building, the investor must obtain the energy certificate beforehand. The energy certificate for a new building is issued on the basis of information from the main project, a written statement of the contractor on completed works and requirements for the maintenance of the building, a visual inspection of the building, and the final report of the supervising engineer. A building can obtain the nZEB energy certificate only if the energy performance of a building and the share of renewable energy sources meet the general requirements for nearly zero energy buildings, in accordance with the Building Act and technical regulations.
