Re: [EnergyPlus_Support] glare

[Rob Hitchcock <RJHitchcock@xxxxxxx>]

Danny,

The glare index calculated by EnergyPlus only indirectly accounts for 
electric lighting illumination by including the daylight reference point 
illuminance set point in the glare calculation (see the Engineering 
Reference documentation "the background luminance is approximated as the 
larger of the background luminance from daylight and the average 
background luminance that would be produced by the electric lighting at 
full power if the illuminance on the room surfaces were equal to the 
setpoint illuminance").  EnergyPlus does not calculate luminance or 
illuminance from electric lighting.  So, if I understand your question 
correctly, the only specification of ambient luminance due to electric 
lighting, is the input value for reference point illuminance set point.
