Why Use Energy Recovery?

An energy recovery ventilation (ERV) wheel recovers some of the air that has already been treated in the building to save on energy. This is done by recycling energy from the building's exhaust air to pre-treat the ventilation air, reducing the load that the heating and cooling system must handle.


Energy Savings in Both Summer and Winter Heating Operations with Enhanced Humidity Control

Ventilation rates using an ERV, can be increased without significant energy penalty. During the cooling season, the outdoor air is dehumidified and pre-cooled. In the heating season, the costly humidification load is reduced through moisture recovery and the outdoor air is humidified and pre-heated.


Reduced HVAC Refrigeration System

When air is pre-conditioned, the required capacity of a unit is greatly reduced. This means when you invest in highly efficient ERV wheel technology, you can reduce the size of chillers, boilers, humidifiers, and pumps.


More outdoor air in a building means better quality air, which means:

  • less illness,
  • better cognitive function,
  • reduced odors,
  • and reduced allergens.

ASHRAE Standard 62, Ventilation and Acceptable Indoor Air Quality, defines the minimum outdoor air ventilation rates required to achieve acceptable indoor air quality. This standard, which is referenced in part or whole by all building codes in the United States, recommends that outdoor air quantities be increased from 5 CFM per person to 20 CFM per person to avoid adverse health effects. Although most owners, architects and engineers recognize the benefits of bringing in more outdoor air, many are concerned about the impact on equipment and operating costs.
