Yep. If the building can retain heat in winter it should be able to prevent it from getting in and be capable of providing circulation and heat escape in summer time.
(Suspect in this case it’s probably more an expectations vs. Reality thing though).
It's a new build from a smaller developer. I don't think much if any thinking went into it. We've already applied solar reflective film to all south facing windows and the air con was the last resort in order to cool down the house in summer. Often seeing internal temps of 28+...
Excellent.
The problem with new bulls is that they’re so efficient at retaining heat that summer can be unbearable.
Been brilliant to have instant cooling capabilities. Cost efficient to. Cooling a room by 5 degrees for a day is less than 1kw of energy.
