This paper presents an optimum selection of a cogeneration system for heat and power generation at University of Technology Sydney, based on technological, environmental, social and economic factors. Five potential cogeneration concepts were developed based on internal combustion (IC) engines, External combustion engines including Stirling engine, Organic Rankine cycle (ORC), Kalina cycle, and Fuel-cells, which were compared. The Organic Rankine Module (ORC) was finally selected. The selected cogeneration concept offers a shorter payback period, lower IRR and net-energy savings, lower CO2 emissions, as well as higher electric-power generation capacity. The outcome of implementing a cogenerated Photovoltaic system is presented to serve supplementary electricity and heat to potentially be used to power double effect absorption chillers. Economic and environmental benefits of integrating a cogenerated Building Photovoltaic system for application at the UTS buildings were studied. Their application under surplus conditions during winter and summer are studied for heat and power generation. The technical and social benefits along with major economic and environmental benefits of co-generation systems and their viability are also considered. This paper presents the outcome of our work-in-progress.
