The purpose of this research is to investigate the technical, economic, and environmental aspects of the use of distributed and renewable production resources which causes reducing the reliance on fossil resources and greenhouse gas emissions. Also, examining the participation rate of renewable energies in supplying electricity, heating and cooling required by consumers, as well as technical and economic examination of the establishment of hybrid systems. Design Builder software has been employed to simulate and obtain the building’s electrical, heating and cooling loads. In the next step, after simulating the exist in conditions, the potential of renewable energies such as solar and wind energy and their combination with the simultaneous production system to supply the building’s load was investigated. HOMER Pro software has been employed to simulate renewable energies. The results indicate that the energy system in Tarifa with 0.318 $/kWh has a more expensive Levelized Cost of Energy (LCOE) rather than Basrah with 0.205 $/kWh. Additionally, the Net Present Cost (NPC) for Basrah and Tarifa is $ 5,557,327 and $ 6,542,097, respectively. Optimized system con-figurations reveal that this system in Basrah generates 728,341kg of CO2 annually while in Tarifa produces 280,702 kg of CO2 annually. The optimal size of the wind turbine, photovoltaic, diesel generator, battery, and converter, are 102 Units, 495 kW, 1200 kW, 994 Strings, 416 kW for Basrah and 87 Units, 393 kW, 910 kW, 785 Strings, and 471 kW for Tarifa.
