I have always maintained that the incredible levels of insulation being fitted to properties now are going to create another climate emergency, one where we will instead move net zero ambitions back 50 years as we retro fit air con to every property as temperatures increase, and we all burn trillions of GW of electricity to stay cool.
One of my clients has just been asked to fit 150mm of celotex in a roof space by building control, as if we had an imminent ice age coming, so we have had to change the design to fit 2 extra windows and added air con to cool it down.
This week in this heat you see residents in flats in cities, being baked alive in modern high rise flats full of glass, where windows barely open for fear of them all jumping out.
Not only will the air con ban need to be removed, there will be a 25 year roll out now to cool our homes down as winters are milder and springs and summers get hotter. Someone got too excited increasing insulation standards by 600% for the odd 2 cold weeks in January we get, when the other 50 weeks are mild to baking hot.
The Conservatives have pledged to scrap what they describe as London’s “de facto ban” on air conditioning in new homes
