Re: Lets do the maths
What do you use for energy storage etc?
The big problem with AC and cooling is the same as heating in cooler climates. YOu can do all sorts of funky things with new builds BUT that is not the problem, it is all the existing buildings that cannot be upgraded due to the design or construction.
Some might be fixable but the costs are astronomical so it is not worth doing and the alternative of pulling all the old building down and replacing them is equally unviable.
That said there are loads of houses built in the 1970s to early 2000 that are just appalling. The problem is that the house owner cannot afford to demolish and start again and the Government is unlikely to throw money at the problem in the form of grants because is will be so disruptive.
Then you have all the stuff from the 50s and earlier without any form of insulation or cavity walls. Pretty much there the only option is to start again so you are back to square one.
