I am working on a control algorithm designed to engage window blinds when a certain solar penetration depth is met using the Energy Management System in EnergyPlus.
I am curious if anyone has had success with calculating this variable before? I believe it will require the solar altitude angle and the solar azimuth angle. Depending on where the sun is at throughout the day the penetration depth will change also depending on the window orientation (changing from facade to facade).
An example of the issues I am running into is with say a 10'x10' building with 5'x5' windows centered on each facade. When the solar azimuth is at 89degrees, the east facade will see a very deep penetration, whereas the north facade will see a very minimal penetration depth. I am looking for a way to calculate the depth which also allows me to discern between the two different penetrations (depending on building orientation).
Any help is appreciated. Thank you!
