• Klems BSDF for daylighting system
• Reinhart sky subdivision (2305)
3-phase-DC method
for each system position (tilt angle):
1 DC for sky (upper quarter-sphere)
1 DC for ground (lower quarter-sphere)
1387 DCs for sun (façade-based
Cartesian grid 5°/5°)

Daylight coefficient approach
• 1 factor for diffuse sky
• 145 sun factors (Tregenza / CIE 108-1994)
Time step evaluation
Emeasurement point = fD * Eh, diffuse + f‘S*Eh, direct
f‘D factor for diffuse sky
Eh,diffuse diffuse illuminance from weather data
f‘S sun factor for current sun position
Eh,direct direct illuminance from weather data
fD = Emeasurement point / Eh, exterior, diffuse sky
fiS = Emeasurement point / Eh, exterior, sun position i
for i = 1, … ,145
