Can Wind Speed be modified through EMS code or We can only Modify it in the Weather Data File?

I am trying to Determine the Effects of Wind Speed on my Simulation. For this I would need to Frequently change the Zone Outdoor Air Wind Speed. Can I do this by an EMS code? or Do I need to Modify the Weather data file every time with the desired Wind Speed?

Any Help will be greatly appreciated.

Yes, it is possible. See If you generate the edd file, you will find an actuator of the kind:

EnergyManagementSystem:Actuator Available,Environment,Weather Data,Wind Speed,[m/s]

Thank you for the quick reply on my question. Bu I am afraid I have a followup question. How Can I generate this EDD file? I checked the Files generated after one of my simulations in EPlus, an EDD file is not one of them. Do I need to adjust something in my IDF file to generate EDD?

Thank you again for your help.

I recommend you to read the EMS Application Guide and take a look at the example files with EMS (or the sample programs in the Guide).

There's an example of a minimal EMS program here (which is needed to generate the EDD file).
