Cooling tips

Solar gain through windows, is a major problem.

Agree.

If the sun beats down on a wall, no matter how good the insulation, the heat will get through to the interior, to some extent.

To some extent?
It won't for example pass through 103mm of brick, 50mm air gap, 100mm of Celotex, 100mm block and 25mm of dabbed plasterboard so long as you've got a hole up your arse.

What would be the U value of that. Can you show a calculation? We can then show you the transference rate. Don’t worry we won’t be asking you to have a proctectomy.

Correct.
The internal wall does NOT eventually heat up.

If that were true, we would have zero need for any heating of cooling systems. The fact that we do need these things, proves you are wrong, but what's new?

I suggest you and brig go for a swim in the sea in March. Based on your knowledge you should find it’s just as warm as it is in September.

Just admit that you keep changing the parameters, so as to appear correct.

That, and quit making stuff up for the same end

Will do, when it happens.

nZHBs are getting close

"to some extent".

That extent being, given that the sun won't be beating down for more than a few hours in any 24, inconsequential

I'm touching the surface of a caity wall now with the sun beating down on it ouside. It's as cold as the rest of the walls.
How many days do I need to wait before the temperature changes even 1 degree?

Nonsense.
Windows and doors are the biggest heat loss factors in any building. Perhaps you could show a scenario where there are buildings without them.
Irrespective the heat of the sun won't be felt through a modern robustly insulated cavity wall as long as you have a hole in your ass.

So yes, absolutely - you would need to wait quite some time, but you do get that, eventually, if the temperature stayed higher outside than inside, some, likely quite small, small temperature rise on that wall will happen...
...and it wouldn't need to be that large a wall temp change to start to have a small on effect the temperature of the room - even at a 1 degree rise, that's one hell of a large radiator!

Once heat begins passing through a wall, if the heating stops, the heat in the wall, doesn't suddenly reverse back out.

No I don’t think he does understand that.

Yeah the answer is a number, not an action.

I’d be impressed if you could detect the U value of a wall, just by touching it.

I make it 0.195. You?

The correct answer for today is 16 hours and 24 mins.

The sunnies in here now and when it firzvrespiear well be inbtge shade on our elevation.
16 hours my arse.
