Author: Saša Rajković

The terms set in RS 52/2010 are used when constructing new buildings or when reconstructing buildings or one of its elements, if this reconstruction affects at least 25% of the thermal envelope, and the change is technically possible (§ 2 of RS 52/2010). Exceptions are listed in § 3 of RS 52/2010.

These rules govern, when it comes to RES-H, that hot water is normally provided using solar panels or alternative installations using RES (§ 13 RS 52/2010). Furthermore, it sets out in § 16 RS 52/2010 that the energy efficiency of buildings is achieved if, in addition to the requirements of § 7 RS 52/2010 (which sets the energy efficiency technical parameters that buildings need to meet):

  • Either at least 25% of total energy consumption for the operation of facilities in a building is provided with the use of renewable energy in the building itself
  • or that the proportion of final energy consumption for heating and cooling and hot water production in the building is produced in one of the following ways: 
    • At least 25% of solar radiation,
    • At least 30% of gaseous biomass,
    • At least 50% of solid biomass,
    • At least 70% from geothermal energy,
    • At least 50% of the heat of the environment,
    • At least 50% of CHP plants with high efficiency
    • The heating and cooling of the building is supplied to at least 50% from energy-efficient installations.

Irrespective of the requirements stated above, single-family houses meet the criteria when using at least 6 m2 (bright areas) of solar collectors with an annual yield of 500 kWh.


This obligation is addressed to all owners/tenants or renovators of buildings. 

Competent authority
