Energy recovery ventilation (ERV) is especially beneficial in settings that require constant fresh air without energy loss. This system works by transferring heat and moisture between incoming and outgoing air streams, allowing for the exchange of stale indoor air with fresh outdoor air while minimizing the loss of energy. This is crucial in environments where maintaining a comfortable indoor climate is essential, as it helps reduce the energy needed for heating or cooling the air.

In environments needing consistent ventilation, ERVs can significantly improve indoor air quality while being energy efficient. They bring in fresh air and help regulate the temperature and humidity levels, making them ideal for spaces that demand constant air exchange without the typical energy cost associated with heating or cooling that incoming air usually incurs.

While extreme temperatures and specific humidity levels might influence an HVAC design choice, the primary function of an ERV is to efficiently manage fresh air intake and the concurrent energy loss. Thus, its use in facilitating constant fresh air without compromising energy efficiency stands out as the primary benefit of the system.
