Re: [EnergyPlus_Support] Re: Fluorescent Vs. LED

["Alex Vlachokostas alexvlachokostas@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Pertinent to the first part of the question: 

The most suited reference that I found is from an 'energy.gov document' 

(Ref: http://apps1.eere.energy.gov/buildings/publications/pdfs/ssl/thermal_led_feb07_2.pdf)  

Based on that document I would use the following for an LED:

-fraction radiant= 0, 

-fraction visible= 0.2, 

-f_convected= 0.80.

I would have the same question, but it seems that data are not available yet.

Therefore my question is: is the field "visible fraction" used in the simulation of the daylight control?

It seems that the lighting level of the installed lamps is determined through the field "Illuminance setpoint" of the object Daylighting:controls:

"This is the lighting level that would be produced at this reference point at night if the overhead

electric lighting were operating at full input power."
