I was wondering if anyone could assist me with this issue.
Actually, I'm not sure how to model variable windows properties (such as U-Value), while such properties would change per timestep. More detailed, I already created a template and now I need to have such window properties (like U-Value) parameterized within the IDF file (e.x., a P1, P2,..). The reason behind that is I should store such (P) variables with new values (which are generated through MATLAB Genetic Algorithm!).
In particular, I need to model for instance four variables, such as P1, P2, P3, and P4; which stand for U-Value of four windows that I have modeled for this case study. In this case, I'll ask EnergyPlus to store new values into those variables and then run my IDF file. This approach would let me have the window properties dynamic and varying per timestep.
Having all said, I'm not sure about the EMS part. For instance, what should I have as the sensor? From the EMS Application Guide, I realized that the EMS Sensor should be picked from the RDD file. However, I'm not able to find window U-value as an output there, as basically window U-Value is not an output!
Just to clarify more, all I need with such EMS setup is something like this (through EMS Program): "set U-Value= P1". But then, I'm not sure how to define the proper setup (such as sensor, actuator, or so on).
I'm really struggling with this EMS setup and any help would be highly appreciated!
