IMPLEMENTATION OF A MODEL THAT COUPLES A CENTRAL GROUND SOURCE HEAT PUMP AND A BOILER FOR SIMULATION USING THE EE4 CBIP COMPLIANCE CHECKING SOFTWARE

Robert Calla, Kamel Haddad, Dominique Lachance

Abstract: Commercial building HVAC systems that integrate a central ground source heat pump with a backup boiler (combo systems) are becoming increasingly more popular in Canada. Natural Resources Canada (NRCan) has developed and implemented a combo system model into EE4 CBIP, the compliance checking software for the Office of Energy Efficiency's (OEE) Commercial Building Incentive Program (CBIP). Considerations in the development and implementation of such a model into EE4 CBIP were: DOE2.1e simulation engine constraints, approximating the heat pump using an electric boiler with corrected COP's accounting for several heat pumps working in sequence, validation methodology, and issues in modelling the reference case for compliance. Future work involves expanding the model to estimate energy savings from using central ground-source heat pumps for preheating domestic hot-water.
