ROCKLAND, Mass. — Airxchange has announced AIRX Estimator for the Environment, a free online estimation tool to quickly calculate the energy savings and positive environmental impact when commercial buildings implement energy recovery ventilation (ERV) technology.

In addition to providing the energy savings, the AIRX Estimator for the Environment helps building owners, facility managers, engineers, and contractors quickly quantify the CO₂ reduction by energy source for specific buildings by inputting three pieces of information:

• City location (currently available for the United States and Canada);

• Number of occupied building hours; and

• Cubic feet per minute (cfm) of outdoor air.

For users not aware of a building’s cfm of outdoor air, the AIRX Estimator provides a cfm estimator based on ASHRAE standards.

“Within minutes, users are able to determine the positive impact ERV can have on their project and the environment,” said Randall Steele, Airxchange vice president and general manager. “As an ambassador for energy efficient buildings, we encourage engineers, facility managers, contractors, and commercial real estate owners to take advantage of this free tool to see the benefits of ERV as an energy-efficient, environmentally friendly, cost-reducing component of HVAC systems.”
