Abstract
A method of ventilation includes receiving at least one signal indicative of an operation of one or more exhaust fans causing air to be exhausted out of a building. The method further includes determining, by one or more processing devices, a total expulsion rate of air being exhausted out of the building by the one or more exhaust fans based on the signal, and determining, by the one or more processing devices, a target fan speed of one or more intake fans configured to draw external air into the building. The target fan speed of the one or more intake fans is determined to achieve an inflow rate that is substantially equal to the total expulsion rate. The method also includes controlling the one or more intake fans using one or more control signals in accordance with the target fan speed.
