How can I design automatic slats that will minimize Heating + Cooling Loads + Electric Lighting in a classroom?
I would like to know the influence that automatic slats would have on the total electric consumption of a school, specially on Summer.
For this season, the interesting topic to assess is how closed should the slats be, remembering that if the solar radiation is being a representative load, the slats will close, but the luminosity will also decrease and, reached a certain level, the lights will rather be turned on, representing an extra consumption.
In a nutshell: for certain weather conditions, it would be better to leave the slats open altogether and meet the cooling loads alone, with no need to turn the lights on.
Is there a way to address this problem with Energyplus?

Is your question how to model automatic slats that open/close continuously (or stepped) based on luminosity?
Or how to model "magic" slats that would open/close at each time step as needed to minimize energy consumption/cost?
Also, define "closed".
A blind comprised of slats has typically two main parameters: the slat angle, and how much of the blind covers the window (typically you can retract the blind from the bottom up, as well as vary the slat angle). Out of the box (no EMS) in E+, you can vary the slat angle very easily, varying the blind coverage is harder.
@Julien Marrec: I don't really know which would be better to model. My only goal is to reduce the costs and meet the glare comfort at the same time. Regarding the 'closed' concept, I guess the best would be, for starters, to fully retract them at night - so that heat would escape through the windows more easily during that period; and keep them closed with a specific angle during the day. This would be the Summer scenario. The opposite would be applied for Winter.
