Currently I'm working on a one zone simulation model in EnergyPlus. The room has one glazed facade, south-east orientated. All other surfaces are assumed adiabatic.
When I look to the illuminance levels at the daylight reference point, these levels stay pretty low. <500 lux during the winter and <1000 lux in summer. I checked my material properties and the 'solar distribution' is set to FullExterior. You can find the .idf file here. Is there something I forgot in my model? Or does anyone know the cause of this?
Kind Regards, Bas
