Hi all
I have a question regarding the daylight factor calculation using the DElight option.
from the DElight output file I got:
Exterior Horizontal Illuminance Components
Overcast_Sky Clear_Sky Clear_Sun
SunAlt 3: 1879.43 1503.00 7347.28
SunAlt 2: 1545.33 1244.38 5682.48
SunAlt 1: 1018.92 1161.06 3027.33
SunAlt 0: 366.91 949.26 360.10
These values seems to be in footcandles, although the illuminance setpoint at reference point is in lux,
Is there is a way to have the output data in lux?
The other issue is that the horizontal illumiance from overcast sky will always be the same,
However, the results show different values with different SunAlt …. I guessed that values at SunAlt1 to 3
are obtained from the whether file, and the value at SunAlt0 is from the theoretical CIE overcast sky .. but
