I’m in an area that cools down at night so i use that as much as possible:
Once daytime temps drop below indoor temps (usually late evening) i open all windows and arrange a couple fans and run them on low all night. My goal is to move all of the hot air out of the apartment and replace it with cool outdoor air.
In the morning, ideally just before sunrise, i draw most/all curtains, shutter blinds, close windows, and turn off all excess lights. During the day i keep everything closed and the air still, and use as few lights as i can manage.
I can generally maintain about 15 degrees (f) cooler indoors with this technique. I currently live on the third floor which is working against me; this was much more effective (20-25 degrees) when i lived on the ground floor.
If i leave the windows open it or worse forget to draw the blinds it gets much warmer indoors than outside. I think my building must have pretty mediocre insulation and my windows are all single-pane.
