The following table is used to outline total dollar ventilation costs for Heat Recovery Ventilators
(HRV's) and Energy Recovery Ventilators (ERV's) for various geographic regions in the United States and Canada.
Costs are for balanced systems using values based on electricity at $0.086 per kWh and fossil fuel at $0.72 per therm
(100, 000 BTU). It was assumed that electric heat was 100% efficient and fossil fuel heat was 80% efficient. Cooling
equipment had a SEER of 12.
Ventilation energy costs would include both fan energy use and the energy required to condition the air displaced by
the ventilation system.
Straight ventilation costs are also included to show the benefit of recovery.
