Discharge coefficient on window

[emmanuelgeraghtyec]

Hello Everyone,


I'm conducting an Overheating Risk Assessment on a room and would be grateful if someone could suggest the opening category and discharge coefficient.

The room will be naturally ventilated and the ventilation opening will comprise an opaque window and perforative decorative metal screen.

I would be grateful if someone could suggest the typical opening category and Discharge Coefficient for the perforated metal screen.

Thank you very much for your time.

I would have attached a screenshot but for some unknown reason, this application won't let me. Any suggestion on this is greatly appreciated.
