Abstract:
Exergy can be used for the optimization of energy losses in different energy system. Exergy is also used for design and performance evaluation of energy systems. In this paper it is investigated the Serbian residential building with photovoltaics and solar collectors on the roof. The building has electrical space heating. Exergy optimization (including embodied exergy) was performed with the aim to determine the maximum value of the generated electricity. The residential buildings with variable temperature in DHW system are investigated. It is also analyzed building energy consumption with or without embodied energy of solar systems and isolation. The buildings were simulated in EnergyPlus, Open Studio plug-in in Google SketchUp was used for buildings design and Hooke-Jeeves algorithm for optimization. GENOPT was used for software execution control during optimization.
