Abstract
A ventilation method and system is described for providing adequate ventilation to an indoor environment while avoiding certain periods of times where ventilation air conditions or other control variables tend to be less optimal or preferable for ventilation, but while still meeting established or future ventilation air standards. The described system and method utilize incremental target cycle times determined based on a regression analysis estimating expression of fractional on time as a function of effectiveness multiplied by fractional on time for a corresponding cycle periods.
