Dear Community,
I am trying to simulate a non conventional adaptive facade that controlled by Air temperature. Since the shape is quite complex, I used the transparency schedule of the shadings. I used EMS to create sensor to get the temperature, and actuator to overwrite the schedule that control the shading. I also set the EMS-computed schedule to track the result. For this stage, I used 0 as the value for the initial schedule, and 1 as the value for the overwrite schedule to easily see the difference if I run the simulation with or without the EMS.
Based on the EDD file and SQL file, the sensor and actuator was executed and the result was as expected. But, strangely, the resulted Annual Load was similar with simulation or without EMS. If I change the transparency value in the initial schedule, the result changes. But if I change the transparency value for the overwrite schedule, it did not change the annual load result, even through the actuator variables did change.
Is there any suggestion why the EMS generated schedule did not able to overwrite the shading schedule? Is it due to the naming or the number for variables that I use?
here I attach some part of my Shading, Output, and EMS script.
