    What do we think of
    https://www.theguardian.com/politics/2019/oct/23/labour-unveils-plans-for-carbon-neutral-energy-system-by-2030s ?

    Don't say its pie in the sky - it cd be done if life-or-death - which it is.

    We cd question the 85,000 Green New Deal-style jobs - more or less?
    And to what standard would "insulation upgrades for every home" be done? as we know, there's a lot more to gren retrofit than that.

    Interesting in contrast to this story:

    https://passivehouseplus.ie/news/part-l-building-regulations/new-building-regs-tragic-for-external-insulation-market

    Definitely needs careful management if it becomes a real policy...

    That article maybe applies to Ireland - I don't see the article in my UK edition of PH+.

    You mean the existing regs Tom, or those in consultation?

    But the labour plan appears to be currently vapourware. The grauniad doesn't give any links to any facts (or even policy statements) I think?

    "Rebecca Long-Bailey, the shadow business secretary" announcing that "Labour will unveil plans" - hasn't happened yet.

    Doesn't Labour have a shadow Environment Secretary, to announce this? Bring back Ed Milliband - he was UK's most clued up Env Sec yet, before getting promoted beyond his competence.

    We're just waiting for remedial work to our blown cavity wall insulation to be done. Whilst adding insulation to cover the top of the inner leaf, we found that the cavity insulation didnt got to the top and was up to 3 feet short! Injection holes had been drilled and filled, but nothing blown in!!

    I suspect that a national insulation program would grind to a standstill after a short while as all the newly qualified installers were called back for remedial works!!

    So what sense does it make to ask us to comment on it or even think about it yet?

    I presume this kills my idea of having partial EWI (on the gable ends of my house only) as this would be more than 25% of the total wall area?

    As said above,

    The most frequently passed law is the law of unintended consequences !!

    As said in the article it will kill off a large part retro-fit insulation market. Retro-fit EWI already has a ROI that it hardly makes sense to do it and this regulation will make it even less so.

    FT, I think you slightly misunderstand the point I was (half) making. The story does indeed apply to Ireland, my point was that a well-meaning central government policy has ended up effectively killing off domestic demand through unintended consequences. It's not a stretch to seeing the same thing happen in GB...

    The wider question is how to roll out an EWI scheme that doesn't require complete overhaul of the thermal envelope (which people clearly can't afford in some cases), whilst ensuring that they can do those works at some unspecified point in the future and that it won't cause poor ventilation/thermal bridging/mould etc. during the interim.

    I suspect, based on other forum threads that it might be OK to leave the windows if the EWI is coupled with (temporarily inefficient) MVHR, for example, but there are a lot of variables to consider.

    Yeah I see - but I think that e.g. JeffB is thinking it applies to his project (or maybe he's in Ireland?) - don't want to start a myth!
