    Free Online Tool Estimates Savings, Environmental Impact of ERV

    Sept. 16, 2013
    AIRX Estimator for the Environment calculates the energy savings and environmental impact possible when energy recovery ventilation is utilized in commercial buildings.

    Airxchange Inc., the Rockland, Mass.-based manufacturer of energy-recovery-ventilation (ERV) components, recently announced the release of AIRX Estimator for the Environment, a free online tool designed to quickly calculate the energy savings and environmental impact possible when ERV technology is utilized in commercial buildings.

    AIRX Estimator for the Environment quickly quantifies carbon-dioxide reduction by energy source using three pieces of information:

    • City (currently available for the United States and Canada only).

    • The number of hours the building is occupied.

    • Outdoor-airflow rate (cubic feet per minute).

    If outdoor-airflow rate is not known, AIRX will estimate one based on ASHRAE standards.

    Airxchange also provides AIRX calculators for direct-expansion, central-plant, and electric heat systems. They are available at http://bit.ly/AIRX_Estimator.
