[EnergyPlus_Support] Re: Moveable Reflector

["luke_dorna" <luke.dorna@xxxxxxxxx>]

Have you looked at the windowmaterial:blind object? It's not perfect, but it does have the tracking functionality and the ability to assign transmission schedules. 

You might at least be on the way towards an approximation.

Since it looks like this module doesn't exist (yet?) and jumping into the Fortran is a little over my head (and not in the budget) I decided to approximate it using reflective shading surfaces with transmittance schedules to control which are on/off. However, it turns out this doesn't work either, because the reflectance doesn't change even when the transmittance does - so even though they may seem like they're turned off, they're still reflecting the same way.
