Performance assessment of residential cogeneration systems in Canada using a whole-building simulation approach

A performace assessment study has been performed on the application of Stirling engine (SE) and Solid Oxide Fuel Cell (SOFC) residential cogeneration systems in single family detached houses in Canada. Detailed mathematical component models, calibrated with measured data from prototypes, were combined into the whole-building simulation program ESP-r with synthetic electricity and domestic hot water demand profiles from calibrated event based generators to realistically forecast the Greenhouse gas emission reduction and efficiency improvement of these new technologies. Simulation models and calibration methods are described. Simulation results for different locations across Canada and for cases with variations of the energy demand of the house are presented and discussed. Finally, conclusions and recommendations for potential improvements of the residential cogeneration systems are given.
