Qsi = 1.1 x ACF x CFMi x STD

Qsv = 1.1 x ACF x CFMv x STD

Where:

 

 Qsi        = Sensible heat gain due to infiltration, Btuh
 Qsv        = Sensible heat gain due to ventilation, Btuh
 CFMi        = Flow of infiltration air, CFM
 CFMv        = Flow of  ventilation air, CFM
 ACF        = Altitude correction factor from Table 10B, dimensionless
 STD        = Outdoor design temperature minus indoor design temperature, oF
 1.1        = A constant, Btuh/CFM-F
