Cost to Operate Ventilation
RED worked with AirCycler and Panasonic to publish two estimating tools for determining the annual cost to operate ventilation systems (RED engineered and authored all the calculations). Each web application includes eight options, from exhaust-only to heat recovery ventilation. The low cost of operation might surprise you. Please give the AirCycler app a try:
AirCycler Annual Ventilation Cost Calculator
Because of the override options, these web applications will give you the annual ventilation cost you need for almost all available ventilation options. Each app includes a Background and Assumptions document link. As far as we know, there are no other apps available for these estimates.
