I have used "zone air co2 concentration" as a sensor and "zone ventilation" and "air exchange flow rate" in the actuator. but it doesn't work. I was wondering if someone could help me to solve this problem? Thanks very much!

What does “it doesn’t work” mean? There is not enough information for someone to help you.

it means that when I change CO2 concentration, there is no change in outputs. May I send you the model?

What calling point are you using? Have you tried different calling points?

I changed the calling point, and it worked. Calling point is "BeginZoneTimestepBeforeSetCurrentWeather". There is another problem. I used Zone Ventilation:DesignFlowRate" as Actuated Component Unique Name. But when the actuator is "on" the total energy is 10 times higher than when it is "of".

Did you write an EMS codo to do what you want? Could you share this file with us?
