Summary

This preliminary study is part of a bigger cloud-based Smart Dual Fuel Switching System (SDFSS) for hybrid heating, ventilation and air conditioning (HVAC) systems. The SDFSS being developed enables flexible and cost-optimized control between the natural gas furnace and air source heat pump (ASHP), allowing simultaneous reduction in energy costs and greenhouse gas (GHG) emissions. To meet the optimal energy consumption requirements and satisfaction of the residents, the employment of smart sensors and software are broadly used. By using experimental data retrieved from an actual near net-zero energy house (nNZEH), this study investigates the GHG emissions as well as the energy costs from the combined electricity consumption of the ASHP and the natural gas consumption from the furnace. The results demonstrate the potentials for large-scale implementation and deployment of such smart control strategy for hybrid residential HVAC system of natural gas furnace and air source heat pump in reducing overall GHG emission in a cost-effective manner in cold climate of province of Ontario, Canada where relatively expensive but clean source of electricity is available. These results demonstrate the potential for large-scale implementation and deployment of a SDFSS in colder climates such as in Canada.
