STEP 1: Convert Input(s) to Base Unit

Maximum Solar Heat Gain Factor: 196 Btu (th) per Hour per Square Foot --> 618.299786027422 Watt per Square Meter (Check conversion here)
Area of Glass: 240 Square Foot --> 22.2967296001784 Square Meter (Check conversion here)
Shading coefficient: 0.75 --> No Conversion Required
Cooling Load Factor for Glass: 0.83 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_{cooling load} = SHGF*A_glass*SC*CLF_G --> 618.299786027422*22.2967296001784*0.75*0.83

Evaluating ... ...

Q_{cooling load} = 8581.82430521124

STEP 3: Convert Result to Output's Unit

8581.82430521124 Watt -->29282.4 Btu (IT) per Hour (Check conversion here)

FINAL ANSWER

29282.4 Btu (IT) per Hour <-- Solar Radiation Cooling Load for Glass
