Cloudy Day @ 85°F Ambient
Total Clg Load = 1300 btu/hr
CFM requirements = 43 cfm
Percent of design cfm* = 22%
Percent of total (3 ton) cfm = 3.6%

Sunny Late Afternoon @ 85°F Ambient
Total Clg Load = 9,498 btu/hr
CFM requirements = 300 cfm
Percent of design* = 150%
Percent of total (3-ton) cfm = 25%

Cooling Load Calculation: Procedure Selection

(Adequate Exposure Diversity - A calculation of the total glass load to see if any hourly total exceeds the 12 hr average by more than 20 or 30%)
