Basically none of us hackers out there saving 10-20% on this and that is going to make a difference whatsoever. It might make us feel good I guess.
What would help is higher regulatory energy standards and better enforcement. I’d settle for making sure builders actually use insulation and don’t leave obvious thermal bypass/bridging across it.
My 20 year old new build property leaks heat due to it being a “plasterboard tent” (thermal bypass due to missing sealing around dot-and-dab drywall). If a building inspector had actually checked this before signing it off, it’d have been rejected.
Yes but the point is you realise all this. And if it was important enough to you (v cost) then you would sort it. Most people wouldn't be interested at all.
Yes regulation and other stuff is sorely needed. But in the context of what an individual can do 10%-20% is nothing to be sniffed at. And I suspect that severely underestimates the savings compared to the average person, let alone the worst offenders.

If collectively it means 0.00000001% change I don't find it provides much "I did a good thing" value and the time would have been better spent fundraising, petitioning politicians, or maybe even just raising awareness towards say... improving a law that makes a collective 1% difference.
