[Radiance-openstudio] OpenStudio-E+ daylighting calculation

[Mostapha Sadeghipour]

Hi Silvia,

Back to your second question:

" In this case are interior artificial lighting consumption results derived
> only from light schedule or are they based also on EnergyPlus daylighting
> calculation?"


It could be either way based on your idf file setting. You may want to
check Daylighting:Controls in EnergyPlus Input-Output Reference (page 376)
for more details.

Best,
Mostapha
