This study investigates the potential of installing an integrated solar powered Organic Rankine Cycle (ORC) with electric energy storage (EES) to provide clean energy to commercial buildings in different climate zones in the US. Reducing the primary energy consumption (PEC), lowering the carbon dioxide emissions (CDE) and increasing the operational cost savings are primary objectives. Firstly, a large office building for eight US climates is studied. The EES is sized to store all the electricity generated by the system. Secondly, the system is studied for sixteen different commercial buildings, in the best climate zone, by considering two operational strategies. Finally, the influence of variable expander efficiency on the system performance is investigated. Results indicate that Phoenix is the best location in the US, among the evaluated locations, to install the ORC-EES. The model for the full-service restaurant shows higher savings and more electricity supply percentage than the other buildings. The model under the variable expander efficiency lowers the yearly PEC by 1.6% and CDE and operational cost savings both by 11%.
