The primary benefit of an energy recovery ventilator (ERV) compared to a simple exhaust fan for providing ASHRAE 62.2 required ventilation is:
A
ERVs provide more outdoor air than exhaust fans of equivalent size
B
ERVs are less expensive to install than exhaust fans with equivalent CFM capacity
C
ERVs recover 70 to 80% of the energy (both sensible heat and moisture) from exhaust air and transfer it to incoming outdoor air, dramatically reducing the heating and cooling penalty of mechanical ventilation
D
ERVs filter outdoor air more effectively than exhaust fans alone
