What is an erv?

An ERV, or Energy Recovery Ventilator, is a type of mechanical ventilation system that helps improve indoor air quality while also reducing energy consumption. ERVs work by transferring heat and moisture between incoming and outgoing air streams, allowing for the pre-conditioning of fresh air before it enters the building.

ERVs can help reduce the burden on heating and cooling systems by using the energy in the outgoing air stream to warm or cool the incoming air stream. This can lead to significant energy savings, as well as improved indoor air quality by reducing the buildup of pollutants and excess moisture.

ERVs are commonly used in commercial buildings, hospitals, schools, and other large facilities where indoor air quality is a concern. They can also be installed in residential buildings to help maintain a healthy indoor environment.

Overall, ERVs are a cost-effective and energy-efficient way to improve indoor air quality and reduce energy consumption in buildings.
