A Quick Guide to Validate Air-to-Air Exhaust Energy Recovery

Air-to-air exhaust energy recovery ventilation (ERV) is a powerful energy efficiency technology. In Minnesota cold climate, ERV systems can displace 70% to 80% of the total ventilation load, making their operation as important to overall building energy use as heating and cooling equipment. They do this by exchanging energy between outgoing exhaust air flow and incoming fresh outside air.
