ENERGY OPTIMIZATION OF SERBIAN BUILDINGS WITH PV PANELS AND DIFFERENT HEATING SYSTEMS

Abstract

Today, renewable energy plays an elementary role in resolving environmental pollution and global warming problems. Solar energy has become a promising alternative source due to its advantages: abundance, pollution free, and renewability. In this paper, possibilities to decrease energy consumption of residential buildings are analyzed. The buildings with electrical energy generated by PV system and different space heating systems (electric heating, district heating) are investigated. The major aims are to determine the area of the PV array installed on the roof and to minimize the energy consumption. Then, it is possible to achieve the zero-net energy building (ZNEB) or positive-net energy building (PNEB). The buildings were simulated in EnergyPlus environment. Open Studio plug-in in Google SketchUp was used for buildings design, Hooke-Jeeves algorithm for optimization, and GENOPT software for software execution control during optimization.
