    Energiesprong is about exactly that.
    How are they doing coping with non-identical houses?

    Tom, when you say 'educate' is that what you mean. Or do you mean 'change behaviour'?


    I meant educate the market.

    People continually tell me new builds are energy efficient... because that's what they read and are told, continually.

    People either haven't heard of Passivhaus or they think it's some whacko hair shirt scheme with stale air inside because "you aren't allowed to open the windows". So much FUD.

    First, Energiesprong isn't a manufacturing solution, despite the image you may have (how it's commonly applied in practice in Netherlands) of bolt-on factory-made panels.

    But, in the case of the bolt-on panels, the cos that use that solution tend to laser-scan each property so they have millimetre-accurate as-built data for each one. Then, on automated lines (or even semi-automation-assisted manual lines, like typical conventional timber-panel new-build producers) it's child's play to custom-make all components to exactly fit each case. It's called Mass Customisation, the successor to Mass Production.

    You've not explained what you mean.

    You've evidenced popular ignorance, which we don't need proving, but not said what you mean by 'education', how it might be done, how it would have any useful effect.

    'Enlightened' people assume that providing evidence (or sustained propaganda) to the ignorant 'educates' them, followed by popular support/demand, followed by action.
    Much experience suggests it doesn't work like that.
    Another approach that sometimes works is 'courageous leadership' i.e. to legislate despite lack of any popular awareness or support, and let the public 'learn' retrospectively that it was a good idea (which they'd always thought but didn't like to say!).

    What do we think about this?

    I have no idea how it should be done and didn't imply any way of doing it as it's not my competency.

    Good news about Energiesprong, hopefully they can cross the chasm to the broader market.

    Tom, you're much better informed than I re; Energiesprong, actually before this I'd never heard of them, thanks, and I don't want to sound like killjoy but your description of the UK Energiesprong approach of advice/ enablement as opposed to the Dutch more practical, ( cladding /cassette), approach makes the cynical side of me raise an eyebrow.
    Follow the money, so they say, EU funding? Housing Associations ( taxpayer funded,and maybe with money to spare)? it's not long before someone under the guise of, " the greater good" spots a nice little earner, talking a good talk, and not much walking a good walk.
    The Dutch approach may work in some cases where social housing was due for renovation anyway. For the majority of muddled, chaotic often lovely housing in this Island, I doubt it. Even for the places that would benefit; at the end of the line, there needs to be someone with a drill/saw/hammer and Energiesprong don't appear to supply that.

    The energy efficiency drive within the domestic market in the UK is largely hampered by being relatively immature, driven by goverment incentives ( which draw in inexperienced businesses focussing on gaming the “schemes”, leading to disappointed customers) and payback periods which to most homeowners have no attraction.
    I would guess most households could reduce their bills by 10% for nothing, just by being aware of useage and gain maybe another 10% through simple draught proofing and insulation at fairly minimal costs. But few choose to do so.
    Massive step change won’t occur, condensing boilers will never achieve the quoted savings purely from how they are used, but the government will still calculate notional CO2 savings on “generous assumptions”.
    The real opportunity is in the design and construction of the homes the country requires, but the sustainability codes have been shelved, in face of opposition from a housing lobby uninterested in raising standards and the threat of increased cost.
    I’m a landlord and this year i’ve 9 flats that will be due new EPC’s, hopefully the same assessor is still in business, i’ll be interested to see if my ongoing efforts of small improvements and the new assumptions on solid walls will have made much difference over 10 years. Plus where its felt any sensible gains can be made.
    The flats are in 3 buildings,
    1870 conversion, 4 flats, terraced
    2002 new build , 4 flats detached
    1950 council block, 1 flat top floor corner of low rise detached block.

    From my point of view there are no improvements that will increase rents or encourage tenants to stay longer, and so are pretty much limited to what can be done through replacement of life expired items or changes to fabric during substantial but required redecoration/ refurb.

    When the EPC’s are due, i’ll make sure all the light fittings have energy efficient lamps, but can pretty much guarantee that any tenant replacements over time will cheap incandescents when the time comes.

    In my view the main gains will come from, building regulations for new build, refurbs, boilers etc. Then the slow tightening of standards in the private rented sector , this should be extended to the council/social sector but very much doubt it will in any meaningful manner.

    Substantial gains in a parliamentary timeframe are all but impossible and so will never be a great priority.

    No no, it was the same procedural enablement approach in Netherlands; many participating cos converged on the bolt-on cassette technique, which being photogenic got much publicity - but other approaches too incl doing it all on-site where appropriate, or chosen by the winning tenderer. Energiesprong has done its industry-stimulant job in Netherlands and is disbanded. Now similar enablement approaches, EU-sponsored, going out (with local adaptation) into other EU countries.

    Your 2nd and 3rd paras - the mess you describe is just what Energiesprong enabling support, model methodology if wanted, seeks to cut through.

    The last thing that Energiesprong needs to provide is 'someone with a drill/saw/hammer' - there's plenty of them, albeit of 'it's a jungle out there' variable quality.

    Worth noting the news: https://www.gov.uk/government/publications/industrial-strategy-the-grand-challenges/missions

    Aiming to halve energy usage of new buildings (I think we can do a bit better than that).

    Aiming to halve the cost of achieving the above in existing buildings.

    No detail on that of course.


    The mission is backed by £170 million of public money through the Transforming Construction Industrial Strategy Challenge Fund. We expect this will be matched by £250 million of private sector investment, meaning over £400 million will be invested in new construction products, technologies and techniques.
    LOL. Chicken feed.

    I had a look at Energiesprong UK website. There are a lot of pretty pictures some of which look like they were maybe from Holland. The UK award, I think, was for 10 homes in Nottingham with work undertaken by Melius Homes. A nice neat, easy I suppose, terraced row; what would be helpful is some info on the project cost per home.

    "UK must secure billions in investment to meet climate targets, MPs warn"
    https://www.theguardian.com/environment/2018/may/16/uk-must-secure-billions-in-investment-to-meet-climate-targets-mps-warn

    "Foreign investment in the UK has fallen 92% since 2016."
    https://inews.co.uk/news/uk/foreign-investment-in-the-uk-has-fallen-92-since-2016-why/

    Investment generally is down since the Brexit vote. Bank of England reported Wednesday that Brexit has caused a reduction in GDP of £40bn representing a loss of tax revenues equivalent to £300 million a week (not far short of the £350m a week some claimed we would "save").

    Boris, who is currently on a jolly around south America, denied the report and said he thought he needed a private jet as the RAF aircraft he normally uses is busy.
