[Equest-users] one fluorescent light source's daily profile with dimming

[David Griffin]

Sehar,

Since eQUEST uses the split flux method of calculating daylighting, you can take one zone with windows and apply the dimming control to it - getting a scalable answer to your question (i.e. the resulting data can give you the answer with the following method: #of lights in space/total Watts for given hour). If different fixture types are used in the same space, a weighting factor can be added to the previous stated equation to get the requested result. I hope this helps.

Thanks,

Subject: [Equest-users] one fluorescent light source's daily profile with dimming

My modeled building has dimming control for the building's fluorescent light sources near the windows. The hourly report shows the daily profile for the lights. This profile consists of electricity consumption for all the light sources in the building. I want to view electricity consumption of only one light source (near a window) being dimmed by a photo sensor.

One option I can think of is to model the building with only one light source near the window and have dimming control for it. The hourly report will then show daily electricity consumption for this light source alone.

Can someone please suggest how a building can be modeled with one light source or any other way to do this??

Regards
