One of the great triumphs of genuine private/public co-operation has been the work of the non-profit Zero Carbon Hub. Ever since its formation in 2008, it has proved to be the acknowledged entity to which everyone turns – companies and Ministers alike – to consider how best to progress towards ensuring that only the most energy and carbon-efficient new buildings are constructed.
But the vast majority of the buildings we shall be living and working in forty years from now have already been built. Precious few of these are even vaguely zero carbon; most waste bucketfuls of energy every day. By common consent we have one of the oldest, and certainly one of the least energy efficient, building stocks in the entire western world.
It is clear that one of the main challenges over the ensuing decades will continue to be to dramatically improve the energy performance of these buildings. This will need to happen at a rate long aspired to. But – as has been shown in the case of the flagship Green Deal Finance policy – right now falling woefully short of even its cost-effective (let alone technical) potential.
