Energy efficiency of buildings in Serbia: State-of-the-art and perspectives

  • In the present paper, state of the art of Energy Efficiency of buildings (residential, business, industrial) in Serbia is given. Special attention will be paid to energy efficiency of already existing or new buildings. Average energy spending in buildings in Serbia is over 150 kWh/m2 per year, while in the developed European countries it is below 50 kWh/m2. This fact forces us, engineers of all specialties, to intensify activities to achieve standards of EU countries. In the present paper the contribution of ventilation losses, thru the windows of low quality, whether they are purely made, or from bad materials, or with no adequate glass, is examined. Besides ventilation losses, which are in our buildings of major importance, special attention will be paid to conduction losses, which are consequence of a quality and energy efficiency of facade. With the measurements obtained on representative building in the Block 34 in New Belgrade, build in the sixties of lust century, all above statements are proved. Massive apartment building construction, during the era of socialism didn't pay attention to energy efficiency. Besides the measurements performed in New Belgrade, the measurements on typical Belgrade attic is given. From this measurements it is shown that attics are much more dangerous to energy losses than apartments itself. Special attention is given to examination and application of plastic windows. All research and measurements explained in the paper are performed in the past five years with the support of Ministry of Science of Republic of Serbia. In the paper, problem of heating, energy efficient light and possibility of solar energy use will be discussed as well. Finally we have to say that Ministry of spatial planning and environmental protection accepted achievements of the scientist in the field of energy efficiency and they incorporated for the first time Certificate of energy efficiency of buildings in Serbia in Building act (Official gazette of RS 72/09).
