The Air conditioning and Refrigeration Institute (ARI) issued a white paper on Energy Recovery Ventilation (ERV).

The white paper, entitled "Characterizing the efficiency of energy recovery ventilation and informing the design of HVAC systems", supplements the ARI guideline V: "Calculating the Efficiency of Energy Recovery Ventilation and its Effect on Efficiency and Sizing of Building HVAC Systems". It describes equipment sizing and system efficiency, essential for design, product selection, and system optimization, when energy recovery is used. Energy Recovery Ventilation conserves energy and reduces electricity demand associated with the heating, cooling, humidification and dehumidification of buildings. ERV technology promises significant benefits and is available today on a wide variety of product platforms. This new guideline should help to ensure that this technology is fully utilized and properly integrated into the HVAC system. More information, as well as the white paper and the guideline, can be found on the ARI web site:
