Solar heat gain
2.4 kW
Contribution to cooling load (BTU/hr)
8,188.8 BTU/hr
SHGC used
0.4
Formula and working
Q_solar = SHGC × Area × Incident solar irradiance
- 1
Collect the inputs
Solar heat gain coefficient (SHGC) = 0.4; Window area = 10 m²; Incident solar irradiance = 600 W/m²
- 2
Apply the formula
Q_solar = SHGC × Area × Incident solar irradiance
- 3
Result
Solar heat gain = 2,400 W
