A building facade has 48 m2 of glazing area. The properties of glass used in the glazing are as follows:
U-value: 5.2 W/m2 °C
Light to Solar Gain (LSG) Ratio: 1.5
Visual Light Transmittance (VLT): 0.6
The average solar radiation on the glazing is 400 W/m2. If the outdoor and indoor set point temperatures are 35 °C and 20 °C, respectively, then the total heat gain (in kW) through the glazing by conduction and radiation is (rounded off to two decimal places).
