[Equest-users] Increase in energy with reduction in U-value?

[Nick Caton]

It's the same reason your body will burn more calories if you wear a
sweatshirt/sweatpants while jogging in warm weather.

 

Too much insulation means you're preventing internal heat gains from
escaping via the building envelope when it's cooler outide (notably at
night time during the swing seasons), which means you must spend more
energy than may be necessary otherwise to cool the building.

Subject: [Equest-users] Increase in energy with reduction in U-value?

 

Hi everyone,

I can't understand how a decrease in U-value for the wall and roof of
building can lead to increased energy consumption.
Has anyone come across this phenomenon in eQuest? Or can anyone offer an
explanation how this is possible.
Any help would be highly appreciated.

Cheers,
Kishan
