Alternatively, an intermittently operating mechanical ventilation system may be used if the ventilation rate is adjusted accordingly. For example, a 121 cfm mechanical ventilation system would need to operate 12 hours per day, as long as the system operates to provide required REM/Rate - Residential Energy Analysis and Rating Software v14.3 This information does not constitute any warranty of energy cost or savings. © 1985-2013 Architectural Energy Corporation, Boulder, Colorado.
