I don't think this is getting the coverage it needs. Scottish government to require passivhaus standard for all new build homes. This is big. Really big. Growing out of lessons from the 70's oil crisis. Passivhaus buildings use very little energy to heat, or to cool. We've known how to do this for decades. It's gross negligence from all western governments that the same is not true of all new builds in the developed world.

@quixoticgeek
It's encouraging. Do we know the implementation date?
And as some have commented, the logistics (supply, standards, training etc.) will need close attention.
In #GreaterManchester, developer lobby are squealing about a 2028 net zero buildings policy, now in a policy climb-down subject to that get out of jail card, "viability".
And what will Scotland do about existing housing stock?
@markhburton @quixoticgeek thank you for pointing the issue with existing home stock. I live in such a building and it’s definitely not easy, nor cheap (!!) to renovate to Passivhaus standards, especially if you have to incur addt’l costs for asbestos removal or installation of heat pump heating in lieu of previous underfloor electric systems
This unfortunately indicates there will be an “energy divide” against poorer families.
@PaulWeber @markhburton @quixoticgeek
It is not mandatory to have an underfloor heating to benefit from heatpumps in existing older houses. However, a very good and state-of-the-art insulating would be necessary at least.
And yes, that will not cheap at all, indeed.
