How to assign a schedule to the louvre shades?

Hey @berrakbalci ,

This is by design in EnergyPlus and it is outside of our ability to change in Ladybug Tools:

The energy results of the building with transparent shades are still not the same as the no-shade scenario.

See this post:

Transparent shades

Hi @berrakbalci , What you are asking here is probably more for the unmethours forum than this one. Or you could probably find your answer by digging through the EnergyPlus Input/Output Reference. If I had to guess what is going on, it looks like this section of the Input/Output reference is probably what’s causing the cooling load to go down with 100% transmittance shades: Shading devices are assumed to be opaque to long-wave radiation no matter what the solar transmittance value is. So, …

EnergyPlus shades are always opaque to longwave radiation and there’s no way to change that unless you remove the shades entirely. The situation is what it is and you can always ask on Unmethours or the EnergyPlus Github if they would ever consider changing this. I imagine that it hasn’t been prioritized in E+ development because longwave heat transfer tends to be very small compared to shortwave heat transfer.
