scope:

This guideline applies to energy recovery ventilation component applications and combinations of energy recovery components with unitary heating, ventilating, and air-conditioning equipment incorporating mechanical ventilation with outside air.

This guideline applies only to energy recovery applications utilizing components tested and rated in accordance with AHRI Standard 1061 (SI) -2011.

Because non-certified data is required for the calculations, the results should not be considered to be "certified".

Purpose.The purpose of this guideline is to establish a method of calculating the energy efficiency of applied Energy Recovery Ventilation components and of heating, ventilating, and/or air-conditioning systems utilizing such components at selected operating conditions. It also provides guidance on proper sizing of cooling and heating equipment when such energy recovery components are applied.

Intent.This guideline is intended for the guidance of the industry, including engineers, installers, contractors and users. It provides a means for calculating the impact of applied energy recovery equipment on the energy efficiency of the heating, ventilating and air-conditioning system at a single selected operating condition. The guideline is not a rating system for Energy Recovery Ventilation (ERV) Equipment, nor does it provide a means of estimating annual energy use.

Review and Amendment. This guideline is subject to review and amendment as technology advances.
