What do you mean by shaded windows. Is that something external like an awning.
Also, what do you mean by adequate ventilation. Are we just talking about sufficient opening windows. Or some sort of mechanical ventilation as well.

It has just occurred to me that you might be referring to something analogous to the greenhouse effect.
Curtains, blinds, a canopy, modern glazing.
Windows/doors open. Trickles open. Anything which creates air movement.
Eh?
None of this part of your post makes any scientific (or otherwise) sense. Which laws of physics do you subscribe to?
Give me a scenario or explain what you mean by eventually? Quantify in temperature what you are theorising.
None of the well insulated internal walls in my house are anything other than cool to the touch, even on the hottest days.
Adequately ventilated, during the heat of the day - no, that cannot work as a way to keep the house cool. If it's 35C outdoors, and you allow that 35C to be ventilated through the house, the house interior and fabric, will acclimatise to that same 35C. In the heat of the day, better to limit ventilation to a minimum, to limit indoor heat gain. Maximise ventilation, once the outdoor temperature drops, on a night, to cool the inside of the house down, ready for the next days heat.
Additionally, limit solar gain, by the use of awnings/shutters/blinds.
Eh? A well insulated adequately ventilated house will be cooler than outdoors.
Absolute nonsense.
More nonsense.
Quite. This is exactly where the solar gain is. Not through the well insulated bits. Full marks.
If it's 40C outdoors, the very last thing you need indoors, is to give 40C free entry into your home. Air movement cools the body down very effectively, a fan can do that very well indeed. You allow free ventilation into the home, once the home's internal temperature is higher than the outdoor temperature, which usually means during the night hours.
Quantify eventually. What temperature do you expect the internal wall surface to be during the heat of the day, on a robustly insulated cavity wall?
A well insulated ventilated house will NEVER reach 40 degrees C in the UK as long as Satan has a hole up his ass. You are talking absolute rubbish.
Give a scenario or explain what you mean by eventually? What is the time limit for example? Quantify in temperature what you are theorising. What temperature rises on the internal surface are you suggesting?
so are your well insulated internal walls the same temp at 4 am as they are at 7pm or are they hotter ....Feeling cooler is not saying they have not heated up as day has gone on
I, and others, have done our best to explain the principle to you. Your lack of education on the subject is very obvious.
Without some active means of internally adjusting the temperature up, or down, what ever the temperature outdoors - it will eventually cause the interior to increase, or decrease, to match it. Insulation, can only ever slow that process down.
No. You have avoided it.
Behave.
In a well insulated ventilated house? Not through the insulated walls it won't. In a greenhouse or conservatory yes.
