Re: [EnergyPlus_Support] Interior Blind - BlockBeamSolar
Arno,
There are several factors interacting under your desired control
strategy. You are deploying your interior blind only when beam +
diffuse solar incident on the window is > 180 W/m2. You should output
this variable so that you can assure that your blind is being properly
deployed. Also, the BlockBeamSolar control uses the input data in the
Material:WindowBlind object, which you have not included in your email
message. The Material:WindowBlind construction must be complete and
accurate enough for EnergyPlus to determine the appropriate slat angle
to block beam when the blind is deployed.
