Question-and-Answer Resource for the Building Energy Modeling Community

Equipment efficiencies in the reference building models are determined according to energy standards, and are based on equipment size. Likely the differences you're seeing is due to the auto-sized equipment capacities in different climate zones yielding a different equipment efficiency as specified in the energy standard.
The efficiencies for different systems and capacity ranges is documented in the Commercial Reference Buildings report, starting on page 35.
