    Skywalker, how do you get people to spend £1500 or more without cultural change, no carrot and no stick?

    How about using the proceeds from a revised stamp duty scheme to fund grants for rennovation. Perhaps arrange it so that you pay say 1 or 2% on a new house but 4 or 5% on an energy innefficient house. Then set up a matching grant scheme so that when you buy an energy innefficient place you either pay the 4% stamp duty or you can avoid it by taking up a grant and rennovating to a mandatory standard. This would encourage redevelopers to do a proper rennovation job not just a lick of paint and a cheap new kitchen.

    You don't! (at least not directly)

    The government spends it out of it's nuclear power station fund thus needing at least three less power stations (by my fag packet calculation).

    I'm past wanting to muck about waiting for people to do things or trusting deveolpers - there is not time.

    What I set out is dead simplistic I know but even if it cost three times as much (in order to be properly monitored and quality controlled by say local building controll and set up costs, allow for difficult cases etc.etc.) what is wrong with just getting on with it. It would be a major programme and affect every houshold (other than the irrelevant number of people that live in real passiv houses and maybe a few thousand other' dwellings) upoin which you could then run an intensive cultural change programme.

    CWatters, aahhh no please no more grants, we have those at the moment, quotes for accredited solar DHW range from £4000 to £10000, I can get the same stuff from Navitron for £1500 to £2000, the grant? £400? For every £1000 HMG spends on the clear skies program how much do you think ends up as a grant? I'd guess 20%

    I have a problem with this whole tax and grant idea, Governments seem to be good at taking our money away with the utmost efficiency, sadly they seem to be not quite so efficient when it comes to spending it...

    Yes

    No middlemen, no grants, just do it. Direct payment to local authorities, mandatory powers to execute programme. Whilst you have to pay someone to install the stuff, the materials costs are known and a well trained chimpanzee can install it (no sucking of teeth & 100% mark ups).

    You don't actually need to spend public money to solve the problem. You can recycle it through the utility companies. We all already pay about £30 a year to pay for the energy efficiency improvements funded by the EEC shceme - soon to be called CERT (Carbon Emmision reduction Target). One thing I included in a response to the draft proposal for 2011 onwards is government intervention to remove the lower unit rate once you reach a certain threshold as your standing charge has been covered. The extra money raised will be better handled by the utilites as they'll do it more efficency than government who would employ about 50 people just to count the money. It also removes the imbalance that people on low income running essential service like lights and a cooker, pay higher per unit charges over all than someone on high income running a bank of recessed halogens, 3 PCs+ network, 40" Plasmas, exterior floodlighting, a tumble dryer and dishwasher, and a spa bath, American Fridge (A Rated american fridges use twice as much as an A rated traditional slim upright - the rating is done on energy use per m3 being cooled!??).

    This EEC/CERT scheme is huge, billions get spent every year. And the utilities have a hard time giving it away! Something I'm trying to help solve at the moment ;-) The biggest problem is 40% of the improvements have to be in the priority group - people who in live in fuel poverty - which means those on beneifts, tax credits or pensions. However I'd like to get those people just outside the group including working people with no spare cash to be covered too. they are finding it increasingly hard to find someone in the priority group who hasn't got cavity wall insualtion or 250_ mm of loft insulation. Whilst people like my brother and best mate who earn nearly 30k a year can't afford the £250 to pay for loft insulation as they have to pay £200 a month on their credit card bills.

    I'm working on a new scheme proposal with a group of other people to get energy advice out to the masses. Having just moved house and tried the exisiting services I'm not too impressed. I've gone via EST and the Energy Advice centres and also tried my utility company. No one has yet returned my call. Meantime my house is dropping to 13 degrees over night unless I keep the heating on. :-(. Thankfully I've pinched the programmable room stat from my old house and so it now only fires the boiler once temp drops below 16 degrees. But I want cavity fill - NOW! I don't want to burn gas to stop the house from freezing - I want it to be warm!.

    On the tax issue linked to SAP- there should be a link but in the guise of incentives. British gas have been running a pliot where council tax payers get a rebate for a couple of years if they make the sensible improvements recommended to them. I can see this could cause problems if there was no penalty side - otherwise everyone's council tax rate would have to go up to make up the shortfall!? The other link to investigate is rather than a specific tax rate for each SAP - set a target to achieve. So say you have a Victorian terrace with a SAP of around 35, the target should be 50 which includes loft insulation, a new boiler, TRV's and double glazing where allowed. Any shortfall should be taxable - ie. you pay to get the measure installed, or you pay tax for nothing. As other measures get cheaper you can riase the bar, on what is expected as a minimum. So by 2020, that 10 year old gas boiler will need replacing with a heat pump, and you should have had your floors insualted from below. This is necessary - I've been talking to lots of people lately - one thing I keep hearing is "I don't believe in climate change". And "I won't do anything until the government tell me I have to". So there. I doesn't matter whether or not they believe it. They'll have to put in insulation a modern efficient boiler and TRV's.

    Stamp duty reductions on energy measures are a great idea. I'd planned to use my savings to put in a heatpump in teh new house and then realised that my £277k house is liable for stamp at 3% not 1%. So £8310, not £2770. Be lucky if I get a new gas boiler now! the good thing about stamp reduction is that the government aren't collecting the money and (inefficiently) redistributing it. You choose how you will do it.

    I should add - becusae of my green interests I just trained to be a domestic energy assessor. Absolutely no interest in HIPs, I needed a tool to measure a homes efficiency - without having to resort to drilling holes, pressure testing and thermal scans. RDSAP (Reduced data SAP) as it's called, isn't perfect, but it's a good start and can be completed in less than an hour (on site). Expect V2 to include the floor type, and possibly direct entry of U values [as long as someone can agree what to do with multi foil :-(] . At the moment the software makes assumptions based on age, so you get an ear bashing by the owner as the EPC report says "Assumed Suspended Timber", when you as the assessor know full well it was concrete! :-( And someone who has an Eco house with over specified insualtion, only gets a U value for the building regs in force at the date the house was built :-(. However this is less than 1% of homes.

    I'm working with a group of other assessors to make the EPC more suitable to people who aren't moving - so you can use it as a tool to help people understand their bills and emissions. Maybe eventually - it could become available nationally. One thing I want to illustrate to people is the concept of savings. Assuming you have it, is £1000 better left in your savings account, or invested in insulation - the rates of return on energy efficiency measures can be into double figures. The only problem is - you can't get the money back so this works best with older families who have no intention of moving (and sufficent spare cash to have left over for a rainy day).

    Finally - long term plan - if you told people about it, (awareness), told them they have to do it (taxation), you then probably need to do it for them. Look up the word ESCo. This will be big business. OFGEM recently took away the 28 day rule. So you can now enter into a long term contract for energy services - which isn't just for energy. It can also include insulation, renewables, advice, monitoring etc etc. Removing the 28 day rule means you can't switch supplier, but it could provide them an incentive to "give" you free measures.

    Whilst I take the point on HMG running projects I'm not sure I trust the utilities to go out of their way to spend money they have in their bank account either.

    If there are allready schemes that can contribute to this then great but to modify existing european programmes is a glacial process at best and my experience of european funding is worse than that of UK governement funding (or at least just as bad) in terms of bean counting/reporting/conferences/monthly returns & crazy output monitoring.

    I prefer to approach this from a national interest point of view rather than spending years working out who can or can't afford it. The simple fact is that if implemented it would reduce the amount of energy this country needs to function, reduce CO2 emmisions by a significant amount and make homes more sustainable. Whilst it is a bit of a trite comment I still think making buisiness repsonsible for people buying less of their product is plain stupid.

    However - you post raises the issue of awareness. EST is starting to become my first port of call if I want to know something. And I then follow links and cross references from there. The typical householder isn't going to want to draft seal under skirting boards, and take the floor boards up to fill with rockwool. Not yet. However these jobs are best suited to DIY as they will cost too much if done professionally to have a payback. But what will make them even think to look to the EST for this advice?

    </blockquote>

    I do. We've already been promise several million if I can get a formal proposal in place and the right people behind it. About 75% of the way there before we get to project initiation.

    If you have an idea and want some money - write an outline proposal, take a look here and get a meeting... with all the utility companies.
    http://www.energysavingtrust.org.uk/cafe/funding/funding/index.cfm?mode=view&id=60

    However some of them have allocated their budgets already.

    It doesn't need to be directly related to electric or gas. They will be given CERT credits for different measures. But outside of theis they have other funding available. The thing to understand is what drives utilities is market share. They all want to increase customer numbers and increase their energy sales. What is becoming obvious is that "green" is the new black. Driving customer demand. Some is greenwash like adverts featuring pictures of windmills that they need to build to meet their commitment under the Renewable Obligation - where tradeable ROCs come from, but the canny energy companies are starting to understand they need to offer some deep green services to cover all the niches. Some are willing to spend what to you and me is huge amounts of money on green services, effectively as a marketing budget. It has to have some commercial benefit - but not necessarily in tangible terms. This is outside of their statutory obligations. So the thing is - get in there and see if you can help them spend their huge budgets on sensible stuff, and not waste it on greenwash.

    I almost don't know where to start with that response!

    One thing I would say is manage your aspirations carefully with regard to large funding bids (did it for years - considerable ups and downs on the way). A 'promise' in funding terms is a letter saying we agree to give you £XX anything else is a possibility (strong or weak but a possibility) in particular if you have significant 'ifs'.

    One of the problems with funding schemes is the process involved in distributing and aquiring the funds. The distributor has to administer, pubicise and report on the scheme and therefor has costs to cover (staff & 'on' costs) these are generally taken from the same fund which the applicants are bidding for resources from. The applicant has to fund the aquisition process (staff & building costs) and recover their end of the admin during the scheme and cover the management cost of implementation; if not from the 'fund', usually made difficult, from so called 'match' funding (other sources) used to lever the bigger funds. Most usually with large schemes, like the one you are proposing, it is delivered by third parties (even if within the same organisation) who then have to bid in to the original applicant for thier part of the project wiht the cost load put on the funding stream.

    What I am trying to say is you cut out all this interim stuff (which takes time and money), have a very simple scheme (loft insulation in all homes to as near as practical to XXXmm), funds supplied to local authorities through the normal channels (minimal extra management cost) delivered by the local authority using their normal mechanisms (delivery staff employed directly with minimal 'on' costs due to the scale of most local authorities) using the normal tender procedures, using extra building inspectors to monitor the scheme on the same basis as other improvements. Then the only agenda is to get the insulation installed, the only 'winners' are the people in the houses and the government. The power generators lose around 10% of their income.

    Easy ;-)

    Cwatters comment on the "local vernacular" hits a sore spot, they (planners) use it all the time without any real justification other than refusal or adding £££ to the cost.
    I wanted to convert a small stone shed into office space, The architect specified rebuilding with breeze block inner layer 50mm insulation ( a joke now, but good 10 years ago) and local limestone outer face (using existing materials) hardwood DG windows and replaced slate roof with kingspan under and their reply was..... "not in keeping with the local vernacular". its next to our block shed and steel roof, with a transport garage next door, brick and asbestos roof with a small white washed/slate roofed cottage next to that

    Peter

    I think that there is a real problem in that most of the measures (beyond, dare I say, loft insulation) are not allways really simple in a refubishment. Quite often you need to do a fair bit of demolition to remedy airtigtness, wall insulation (other than cavity)and floor insulation. Along with that getting your head around cold bridging and how to remedy it in a refurb is very tricky. What makes it more complicated is making an old house airtight can have negative consequences if entered into unwarily, as can insulation without a clear understanding of the structure and ventilation requirements. It all gets technical really fast.

    The benefit of this forum is that you get a range of opinions from people who are either pretty good at what they are talking about and/or are actually doing it. Also all are patient and polite with newcomers.

    I would be interested to know if it is in part the very active renovation threads on this forum which has led the GBP to produce a renovation volume of the GBB. Clearly we cannot begin to adress houshold sustainability without dealing with the existing stock in some way as well as promoting all new build to very high standards.

    The simple truth is that HMG, like most of them, has only just got round to low energy lightbulbs. Most of us got to them in the 80's and have moved on a bit.

    From a new boy on this site I just wonder if anyone has seen the Energy Efficiency Reports which come as part of HIP's nowadays? The last couple I saw had me in hysterics. They only play lipservice to energy efficiency. Apart from the dumbed down 'white goods energy consumption ABC style rating' it has recommendations such as change lightbulbs to low energy versions. All well and good but the last one I saw went on to say that you would get your money back in 13 years - wow. Most people move every 5 years or so. That is hardly an endorsement or an incentive. People are inherently selfish (not everyone but please excuse the cynic in me) and with such a long pay back time will not see the incentive to invest in energy saving where someone else will benefit. No one even asks to see these reports let alone takes any notice of them.
    If you are going to play sticks & carrots you need to do it through the tax system. If you went to buy a house and the council tax was going to cost a lot less because it was heavily insulated you might well prefer that property over a similar one being penalized due to poor insulation. Of course this would necessitate a bit of joined up writing between assessors, councils and government and a realistic assessment of very different property types and listed buildings, etc. Above all, owners need cash/tax incentives to carry out work. Perhaps then you might get some of Skywalkers simple quick results taking place. You need a stick AND a carrot. Tax incentives for doing it. Tax penalties for not doing it.

    Skywalker,
    Hope you didn't get the wrong idea with my last post, I was merely pointing out that those of us frequent this site are the most likely to visit the EST site, it is the majority of the nation that need to be pointed in the right direction.
    I disagree that a room by room solution envolves a degree of demolition, there are new board type materials on the market now that offer a degree of insulation and air tigthness for floors and walls, not I grant you as good as cavity insulation and lifting the floors to add insulation. Air tightness can often be resolved with mastic and crazy foam, it's not a purist solution but it is cost effective and that is the important aspect as Jeff aludes to, cheap simple solutions made widescale across the country have got to be better than headline expensive solutions. Thermal bridging issues are perhaps a step too far but good double glazing can compensate.
    Treated room by room the problem is not as difficult as you make out, the secret is not to set your sights too high.

Nothing against CFLs - my house it full of them - but I think using them as the answer to climate change is wearing a bit thin. At least they are cheap and easy to install. And we still have about 100 million left to replace. OR something more than that. I think they sell 100 million standard bulbs a year :-(

    Jeff, have you seen a real EPC - or just read about them in the press. An EPC doesn't have payback times on them. Measures are broken down into "Low Cost" (Under £500) "Higher Cost" (£500-1000) and "Further" for things like PV and Solar H/W. The Fridge rating is show alongside the Actual SAP score, and potential SAP score - which you'd get if you implemented th Low Cost and Higher cost measures (but not the Further).

    So in my house Current SAP was 58 and could be bought upto 70 by
    Lower cost:
    increasing loft insulation from 100mm to 250 saving £24 per year (SAP upto 59)
    Replace all non low energy bulbs saving £26 per year (SAP upto 61)
    Higher Cost:
    Upgrade existing gas boiler to condensing boiler saving £133 per year (SAP up to 70).

    I'd call that informative not useless.

    What's even more useful - is knowing that installing a PV system (£8000 by my rough calcs) would save me only £34 per year. So I won't be buying one of those then! IT's still useful info - as it says - stick to the sensible stuff.

    Finally I've included a sample of the text describing the measures just to show that theres some substance to what is contained...

    Upgrade loft insulation to 250mm
    Loft Insulation laid in the loft space or between roof rafters to a depth of at least 250 mm will significantly
    reduce heat loss through the roof; this will improve the levels of comfort, reduce energy use and lower fuel
    bills. Insulation should not be placed below any cold water storage tank, any such tank should also be
    insulated on its sides and top, and there should be boarding on battens over the insulation to provide safe
    access between the loft hatch and the cold water tank. The insulation can be installed by professional
    contractors but also by a capable DIY enthusiast. Loose granules may be used instead of insulation quilt;
    this form of loft insulation can be blown into place and can be useful where access is difficult. The loft space
    must have adequate ventilation to prevent dampness; seek advice about this if unsure.

    Upgrade existing gas boiler to condensing boiler
    A condensing boiler is capable of much higher efficiencies than other types of boiler, meaning it will burn
    less fuel to heat this property. This improvement is most appropriate when the existing central heating boiler
    needs repair or replacement, but there may be exceptional circumstances making this impractical.
    Condensing boilers need a drain for the condensate which limits their location; remember this when
    considering remodelling the room containing the existing boiler even if the latter is to be retained for the time
    being (for example a kitchen makeover). Building Regulations apply to this work, so your local authority
    building control department should be informed, unless the installer is registered with a competent persons
    scheme{1}, and can therefore self-certify the work for Building Regulation compliance. Ask a qualified
    heating engineer to explain the options.

    The next step is to make sure the new owner gets their hands on the report. Something that isn't happening at present. However the key stakeholders involved are keen to help make this happen.

    I'm a purist, wow!

    I suppose over the past year or two I have immersed myself in how to renovate my 1932 colander as well as is practical.

    I get you point totally about cheap and simple. Small levels of insulation where there are none are fine if doing more is genuinely hard as the biggest gain is in the first few 10's/100mm - lots more is however lots better in the long term. With airtightness it is a rather different as something is either airtight or it isn't. I'll meet you half way on dealing with drafts.

    Thermal bridging can be a big problem where you have a well insulated area either interspersed with thinner strips of insulation or bordered by less well insulated materials = condensation most of the time. It would be a shame if many people did their first but of 'green' DIY only to find they were then farming grey moulds.

    As for bleedin' spray faom a free can is probably a good idea just for people to practise with the stuff - nightmare.

    Draft proofing is way and away the most cost effective thing to do.

    Insulation 250mm deep should go between and over the ceiling joists.

    I couldn't agree with you more Tony. Being in the process of following your advice and starting to reap the benefits in terms of making my place air tight and as a result budgeted for and air tightness check & mechanical heat recovery ventilation if needed - I am convinced.

    But as an initial countrywide step do you mean draft proofing as most people would understand it (doors/ windows/loft hatches/spare chimneys) or do mean the more thourough floors/joists/service entries/strucutral joints (envelope sealing) route that really adresses air change rate. The latter is more problematic at a national level due to the different construction methods faced with renovation (suspended wooden floorboards in older houses to the plasterboard tent issue you have highlighted). I would be inclined to think that a really good go at simple/DIY (doors & windows) draft proofing would be a cheap (£50-100?), quick, simple win but I'm reaching the edge of my knowledge/learning in terms of how much difference that will make in an average property with many other routes for infiltration.

    In other words is there a similar simple to apply scale (other than if you can feel a draft seal it). I have read that best practice air leakage rate is 3m3/h/m2 & good practice is 5m3/h/m2 however unlike insulation it is hard to translate this into something tangiable and simple for the DIYer to measure (like a beufort scale for houses).

    skywalker - have you considered taking the airtightness training - I found a company offering it for £145 + VAT- http://www.chilternfire.co.uk/training/thermalserv_training/air_leakage_testing_explained.html. Haven't been able to get a price on hiring the equipment yet but purchasing is a b it pricey - like 4 figures pricey! But with hiring the idea is you can keep retesting and see how far you still have to go without paying £100 everytime you want it testing. Combine some canned smoke to see where the escape points are and you can do regular tests for little extra outlay. Not sure if it would qualify you to offer a service, but at least you'd be able to do DIY!

    The link looks more like awareness/preparation training rather than training to become qualified to do the test at any meaningfull level. I suspect you need an engineering qualification or a very good understanding of the physics of air movement in buildings/gas analysis in realtion air dilution/atmospheric pressure before attempting to understand the output of a proper air tightness/ventilation test.

    All that said I plan to walk around with a joss stick on a very windy day/very cold day with the house very warm before I put back all my floors just to find any massive gaps I may have missed. I will get a pressure/ventilation test if my heating bill does not improve as it should or I start to get a local rise in fungal/algal biodiversity (again prior to fixing down my new floors - in many months time).

    I do not need a pressure test yet as I am well aware that I just about warm the air up to a nice level as it whistles through my house on its way to the Peak District or Lincolnshire (although as each day passes it gets a little better).

    Draught proofing of windows, doors and loft trap are the first step, commonly not done, for the majority.

    Step two is air sealing arround and under frames, round service entries from lofts, floors and walls.

    Step three is air leakage sealing under floors, behind walls etc to get to a reasonable level of non air leekyness.

    Most haven't done step one yet and just because you have replacement windows does non necessarily mean that you are there yet.

    Cool

    So for my average government fund of £1500 per household in the UK I get loft insulation and draught proofed windows, service entries, doors & loft access (including management costs). This should give an average energy saving of between 20 -30% per houshold and off the back of this action a programme of carrot & stick is launched for the trickier/more disruptive stuff to engender a lasting cultural change in our approach to home improvements and secure a minimum reduction in household energy use in the existing stock to 50% of todays figures by 2010-15.

    How are we doing Bowman?

    When do I get to meet Sarah Beeny??
