Are you saying the sun directly shines into the windows at that hour? Your windows must be on a slant, or you're confusing it with an ultrabright background full of reflection.

https://www.energy.gov/energysaver/energy-efficient-window-coverings

The modern energy efficient windows have a transparent metal film in them that totally blocks UVA/B radiation, and that technology works very well to prevent heating and damage from that part of the spectrum..

None of the sun blocking performance is to be confused with the basic thermal conductivity/ resistivity of the window. That has to do with heat leakage by conduction and is an entirely different matter.

The modern variable speed a/c technology should be controlled in such a way that it only runs high speed continuously when the measured temperature exceeds the setpoint by about 3oF, otherwise if runs at less capacity. An extended high capacity run means it's either trying to catch up with an extended setback, or the capacity can't keep up with the heat gain from the record outside temperatures.

Alternatively, why not make air conditioned beds (bed+tent+A/C)thus no
need to cool the whole apartment. It would also be easier to get some
relief to old buildings without A/C. Make the tent walls thick to
reduce heat transfer, inhibit any light entry and attenuate street
noise.

With such beds, one could have a nap during siesta or work night shift
and and sleep during the day.

The right blinds would stop that; the other trick, is broad eaves over the windows,
so in winter (sun low in the sky) you get direct sunlight through windows, but in summer
(sun high in the sky) they're in shade most of the day. It earns you about 5 degrees F
both for heating and cooling.

That's interesting, because the ancient architecture in that country
shows that they knew how to cool down their houses passively.

You have not considered the latitude and the orientation of the windows.

They also block UHF/microwave signals and it can be hard to use

LOL- there's an industry pushing trillion dollar annual that disagrees with your assertion.

In U.S. window area on average runs 10% of the floor space. It's uncanny how uniform that is. People beat it with sun rooms, picture windows and other unnecessary stuff. For the most part there're no reports of loss of cell phone reception in the majority of dwellings.

loss of cell phone signal is another fake distributed by morons

Don't bother. Recent estimates are the Earth's core is hotter than the surface of the sun. Everybody except you can understand that's not exactly conducive to absorbing heat from the surface.
