The article compares carbon dioxide (CO&sub2;)-based method with cubic-feet-per-minute- (cfm-) based method in monitoring ventilation. The two methods may be used in order to provide healthy and productive indoor environment under ANSI/AHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality. According to the author, the CO&sub2;-based method is dynamic while the cfm-based method is static.
