Does the zone have an HVAC system that controls to a set point? If so, does the HVAC energy use change?
Are you calling the EMS program at the correct place in the simulation? You could try different calling points.

Did you report the transmittance using a report variable?
Did you report the direct solar through the window?

Hi everyone!
I want to simulate an overhang that closes and opens depending on the brightness of the sun and inside temperatures.
I want to implement it in a dynamic way!
They previously told me i have to use an EMS. Now is the problem the EMS still works in a non-dynamic way i think, cause the results stay the same as with a simple working shedule. The EMS works proparly when it has to determine if the overhang should open or close (transmittance = 1 or 0), but the next step would be that the inside temperature of the building varies with this opening and closing.
And this just doesnt seem to happen.
How do I implement this overhang in a proper way?
Greetings
