Surely you are not an idiot.
If the outside temp is 90F and you turn off your AC the inside tempt will be 85F by the time sunrise rolls around. At that point no one can turn on their PCs or any other equipment or even sit in the “empty” rooms — the AC is playing catchup.
Unless the AC is massive, like what is used to freeze food, it will play catchup all day until sundown.
Repeat.
In such warm areas AC has to run continuously. Even with excellent insulation.
I did NOT mean to imply that businesses should completely shut off their A/C’s overnight, but they could raise the temperature control by about 5-10 degrees.
Well-insulated buildings can certainly retain enough residual cool air overnight when the direct sunlight isn’t affecting them, even when outside temps are hot. Anyway, I’m talking about timer-equipped thermostats which can cut back on A/C about 8:00 pm and turn them by down to the desired temperature a few hours before working hours. This is already done by many businesses to save on electricity expense.
And the completely vacant office spaces don’t need A/C on at all. There are many BILLIONS of cubic feet of these.
