What is the primary benefit of an energy-recovery ventilation system?

The primary benefit of an energy-recovery ventilation (ERV) system is that it minimizes energy loss. An ERV system works by exchanging the incoming fresh air with the outgoing stale air, transferring heat and moisture between the two airstreams. This process allows the system to pre-condition incoming air, which means that it uses less energy to either heat or cool the air before it enters the living spaces. As a result, energy consumption for heating and cooling is reduced, making the building more energy-efficient.

This capability not only enhances energy savings but also contributes to maintaining a comfortable indoor climate, as the incoming air is tempered in accordance with what has already been conditioned in the space. Therefore, minimizing energy loss is a critical function of ERV systems, making it a desirable feature in modern residential and commercial ventilation strategies.
