Energy efficiency of the buildings in Serbia

Around 70% of energy in Serbia is lost through walls and window. The current situation in Europe is 20 to 30% better, with the tendency of further intensive improvement. Wasted energy is wasted money. European residents are very careful about real estate purchases. Building with higher energy efficiency have higher market price. This trend will spread to the Serbian market because the energy prices have a clear and constant growth trend.

According to the Energy Performance of Buildings Directive all new buildings should be so-called zero-energy buildings that produce and consume their own energy. A similar trend awaits Serbia in a relatively near future .

While modern architecture is going to deal with the issue of how to make the best thermos from their apartment, the question is what to do with old energy-consuming buildings. In Serbia, 33% of buildings are older than 50, and 45% are older than 25 years. According to the analysis of the German Organization for International Cooperation (GIZ), most of these residential buildings and houses in Serbia belong to the lowest energy class.

Nevertheless, there is a great potential for energy savings in Serbia and the implementation of energy efficiency measures in the construction and maintenance of buildings, especially if we consider the fact that electricity consumption is twice as high as in the European Union.

The European investment calculation is as follows: On the invested EUR 1, it returns EUR 7.5 in a relatively short period of 3 to 8 years.

In line with European trends, Serbia is expected to achieve energy savings of 9% by 2018 in comparison to 2008.

Primary measures for improving energy efficiency are focused on converting existing facilities into "small" energy consumers. This is achieved by placing adequate isolation, replacing the exterior joinery, and by improving the heating system.

One of the most favorable ways to improve the energy efficiency of windows is the installation of thermal insulation films. During warm days, these films refuse solar heating, while during the winter they prevent heat loss. Thus, by installing window films, you can reach annual energy savings up to 15%.
