Cooling tips

Its well known that highly insulated buildings heat up due to overheating.

Nonsense.
Please read more thoroughly. And at least understand what you do read.

The grass hardly grows in this weather so no energy used there to cut it.

It has been the easiest year I can remember for grass cutting, it took so little effort on the tractor, to get the first cut done - and since then it has hardly needed doing at all. Last year, it was a twice-weekly job, just to keep control.

 

[noseall]

But why. What is the science behind it.

MBK has shown you a report that says flats overheat. It's more to do with the idiosyncrasies of the structure and poor ventilation.

Largely irrelevant to regular housing. Inadequately insulated/ventilated lofties are the worst culprits in that respect.

I already knew from the news that flats have a particular problem.

But my first thought is that some of the other factors MBK raised in his other reply seem sensible. I am going to try really hard to get my head around it.

- human occupants.
- Infrastructure inside the home
- Solar gain on windows.

My first thought is that sounds sensible. I am going to try really hard to get my head around it.

Maybe it could be from the fact that you have to open doors to go in and out which lets the heat in and it stays there or opening windows and also sunlight through windows.

I often think that solar gain is the big factor. It certainly feels that way!

What sensible factors has MBK raised?

This is only my first instinctive thought, and it takes me ages to think through things like this. But he seems to be saying that if you have a highly insulated building, then any heat generated inside the structure, by sources such as human activity, solar gain, and electrical appliances, will take a lot longer to dissipate because of the insulation all around the house.

Only if it is poorly ventilated and in extremes - i.e. all windows would need to be closed, no shading on the windows, a lot of glazing on the South side, doors closed throughout the whole day, poor glazing i.e. no Solar or low E glass etc, no trickles.


However the insulation continues doing it's job.

I am thinking of the situation we occasionally get when you get a run of very hot days with very still nights. Even if you open all the windows at night, there is almost no heat loss. But as you pointed out earlier, the insulation means that the house would not have got as hot in the first place. Anyway, this is all far too complex for me and there are too many unknowns.

Yes so if you had no windows and never opened the front door or letter box then or had any appliances that produce heat - then a well insulated house will stay nice and cool in the summer.

our workshop is in a disused supermarket, that seems to be largely made of concrete - the hottest it ever gets inside is about 17 - (freeze your nuts off in the winter) but fantastic in hot weather - going out of the door last week was like stepping into an oven

Idiosyncrasies aside - mitigating heat gain is far easier when a house is robustly insulated than when it is not. There is zero benefit regards anything thermal, to not insulating a house.

That's all you need to get your head around.

Yes but remember the likes of noseall deliberately grab the wrong end of the stick just to start arguing.

Next time, I'll poke him in the eye with it.
