A multigeneration system, which consists of wind turbine, concentrated solar collector, organic Rankine cycle, and ground source heat pump, is proposed, analyzed and assessed energetically and exergetically for residential applications. The useful outputs of the system are electricity, hot water, heating and cooling. The proposed system is designed for a green building and evaluated with energy and exergy efficiencies. The effects of varying several parameters on the energy and exergy efficiencies of the system are investigated. Furthermore, the levelized cost of electricity and net present cost are determined, and the proposed system is optimized based on these parameters. The optimization determines the net present cost to be $345,481 and the levelized cost of electricity to be $0.181/kWh. The energy and exergy efficiencies of the overall system are found to be 46.1% and 7.3%, respectively. (C) 2016 Elsevier Ltd. All rights reserved.
