A Particular Glazing System Has Center Of Glass Characteristics As Follows U Value W M C 2 7 Visible Transmittance 0 1 (57.32 KiB) Viewed 45 times
what's the total solar heat gain (W/m2)
A particular glazing system has center-of- glass characteristics as follows: U-Value W/m²-°C 2.7 Visible Transmittance 0.78 SHGC Incidence Angle (Beam Radiation) 0⁰ 40° 50⁰ 60° 70° 0.70 0.67 0.64 0.58 0.45 80⁰ 0.23 Hemispherical Diffuse 0.60 Consider the following scenario: Beam solar radiation (measured in direction of travel) 2 660 W/m² strikes at incident angle 45°. Diffuse solar radiation = 155 W/m² (measured in the plane of the glazing). There is no interior shading device.
