Britain's building regulations are biased against AC, despite the Climate Change Committee declaring that all new hospitals and schools should have AC as standard.
The rules force housebuilders to maximise passive means of cooling before considering AC.
The result? Most new homes have tiny windows, but still can't cope in Summer.
While housebuilders in London have been told to maximise 'dual aspect' which cuts into valuable floorspace, while failing to cool our homes in 30C heat.
Britain is a hot country now. But we don't build for the heat. Overheating regulations prioritise passive cooling and treat air conditioning as a last resort.
It's not enough any more. Active cooling should be normal in new homes.
