[EnergyPlus_Support] Re: Lights luminous efficacy

Stefano,

You can coltrol the luminous efficiency with the Daylighting:Controls object. You set the Illuminance (in lux = lum /m2 ) at the maximum power (in W) for the light.

I see it's possible to size a lighting system either in W/sq.m. or setting the lighting level in W, but is there any possibility to set the luminous efficacy of light sources? I was interested in setting up different scenarios with different lighting technologies.
