I open it fully if the car is really hot, like over the weekend, and the windows to let all the hot air out, tbh I mostly drove around town this weekend so had the windows down, sunroof slid back and the A/C just blowing on my sweaty feet, sod the MPG's!!
If not I just let the bulk of the heat out then close up everything and let the A/C do it's work, why do you ask??
On a hot day if I'm leaving the car outside, I put the sunroof in tilt mode so hot air doesn't build up inside the car. The gap is only small but but you're not sealing in the heat with everything closed and the car is still locked and secure.
