Create dynamically adjustable louvers/fins for EnergyPlus

Hi @marped,

It will be partly as you explained. However some parts can be made more simple:

@marped

Conduct a whole year daylight simulation to register when illuminance levels on the exterior window surface exceeds as given threshold level.That can be turned into a list of hourly true/false indexes for the whole year. Now I can know when the shading should be activated.

This is not the case. You can simply ad to all shade generators the same shade control type and set point. For each window and orientation this will be calculated.

@marped

This could be solved mathematically by taking in the azimuth of the sun. You might chose that the lamellas should rotate 10 degrees of the suns azimuth. Before noon, the lamellas should turn right and after noon they should turn left to block out the sun. All this information should then be converted into schedules with hourly data which don’t contradict one another, which would be extremely time intensive.

These scedules you can generate directly from the EPW file. If take steps of 10 degrees you will need 18 schedules. If you take bigger steps you will need less schedules.

@marped

Furthermore, schedules should then be made seperately for the east, south and west orientations, as illuminance levels differ depending on the orientation of the investigated surface.

As all different orientations are related to each other, you can simply define for each timestep a set of orientaions based on the facade orientation. This will save you time and make the script less complex.

I agree it is a bit a work around.
