    If a developer states:

    "We reduce the energy demand and carbon footprint of heating our homes by improving wall and roof insulation, before fitting complex technologies. This means that residents benefit from consistent energy bill savings while their long term maintenance burden and costs are kept to a minimum."

    What do they mean, exactly?

    And if one of their reps tells you that these same energy efficient homes "are built to Code 3 standard, compliant with current Building Regulations".

    Would you be justified in giving him a quizzical look and asking him if he was having a laugh?

    It means we just scraped past the regs but you the prospective householder can feel warmth (not literally) and wellbeing

    Umm is that before or after the free 42 inch TV?

    how do you spell skeptcals?

    It is just fluff for the lay person.

    And, if an average 'joe' chooses to buy a Code level 3 house over something older and less efficient, it is a tiny step in the right direction!

    Hi,

    It comes back to a point I made in another thread about perception of regulations (dodging thereof). The converse is that compliant with regulations is touted as good, if they marketed as exceeds by xyz or whatever, it would show they recognise the regs are the bare min we should accept.
    Cheers

    My sentiments entirely, Timber.

    If you're meeting the minimum required BY the Regs, you're only doing what you HAVE to do by law, so such touting of the minimum standard as being somehow meritorious shouldn't be allowed. It's an inference too far.

    It's claiming merit for not breaking the law.

    There are no more "energy savings" to be had than you'd get from buying any other house built to the same standard.

    And what "complex technologies" are they fitting into a Code 3 house?

    I think most will be familiar with the minimum expected in the most basic of new houses these days...

    The home will have to be 25% more energy efficient than one built to the 2006
    Building Regulations standards. This could be achieved by:
    • Improving the thermal efficiency of the walls, windows, and roof as far as
    is practically possible (by using more insulation or better glass for example);
    • Reducing air permeability to the minimum consistent with health
    requirements (a certain amount of air ventilation is needed in a home for
    health reasons);
    • Installing a high efficiency condensing boiler;
    • Carefully designing the fabric of the home to reduce thermal bridging
    (thermal bridging allows heat to easily escape between the inner walls
    and the outer walls of a home);
    • Possibly using district heating systems or low and zero carbon technologies
    such as solar thermal panels or biomass boilers to help heat the hot water.
    The home will have to be designed to use no more than about 105 litres of
    water per person per day. This could be achieved by fitting a number of items
    such as:
    • 6/4 Dual Flush WC;
    • Flow Reducing/Aerating taps throughout;
    • 6-9 litres per minute shower (note that an average electric shower is about
    6/7 litres per minute);
    • a smaller, shaped bath – still long enough to lie down in, but less water
    required to fill it to a level consistent with personal comfort;
    • 18ltr maximum volume dishwasher;
    • 60ltr maximum volume washing machine.
    Other minimum requirements are required for:
    • Surface water management – this may mean the provision of soakaways and
    areas of porous paving;
    • Materials – this means a minimum number of materials meeting at least a ‘D’
    grade in the Building Research Establishment’s Green Guide (the scale goes
    from A+ to E);
    • Waste management – this means having a site waste management plan in place
    during the home’s construction, and adequate space for waste storage during
    its use.

    ............

    But to get to Level 3 you need a further 46.7 points. So the builder/developer
    must do other things to obtain the other points such as:
    • Providing drying space (so that tumble dryers need not be used);
    • Providing more energy efficient lighting (both internally and externally);
    • Providing cycle storage;
    • Providing a room that can be easily set up as a home office;
    • Reducing the amount of water than runs off the site into the storm drains;
    • Using much more environmentally friendly materials;
    • Providing recycling capacity either inside or outside the home;
    • Enhancing the security of the home;
    • Enhancing the sound insulation used in the home.

    ...Anyone care to point me to the "complex technologies" in that last list?

    Code 3 energy standards can be achieved with good insulation, airtightness of 3 or less, MVHR and a gas combi boiler. We completed 23 units on that basis last year.

    No need for any eco bling renewables - just straight forward good design.

    Note: these were social housing units done to a minimal budget.

    Add some PV and Code 4 is achieved. We did 36 units in 2010 to this spec. Simples.

    I would prefer a low energy home to an energy efficient one -- a lot of educating needs to be done yet.

    That's the distinction I tried to make to that rep, Tony. He just looked blankly back with an expression that made it clear he wished I'd just disappear. :bigsmile: I had the mischief in me, but had to get on to somewhere else so had to suppress it.

    Disappointing thing is that if the scheme is turned down it won't be because it falls short of what's possible and desirable.

    I still see developers advertising "double glazing throughout" as if it is a benefit!
  3.  
    It might still be seen by some as a selling point, but they could have mass produced UPVC 3g for the same money, so even those marketing / sales folk aren't exactly upto date. But if the buyer dosn't even know then they win. So I would like to inform the public more. Its a bit like working in an office where one bod knows how to get the whatever going (MS office / coffe machine)and when challenged always sayes Oh I thaught everyone new that - which translates to I kept that a secret.
    So the more the public is informed the more they can raise their expectations.

    I though it was now a requirement for a DISPLAYED EPC?

    There is a new development going up near me and the estate agent didnt even know what en EPC was, let along what the new houses were going to achieve!

    If developers were forced to display,state,advertise the EPC as per fridges etc in Currys... Then quickly buyers will become informed and empowered to make more informed decisions with regards just how "energy efficient" their new home shall be.

    I even noticed that Porsche were advertising the energy rating/efficiency really in the same way as fridges last time I walked past their Mayfair showroom.

    I house must have an EPC (at least in England) before sale AFAIK.

    I have repeatedly written to one of the larger Internet house finder that doesn't even display them, let alone let you search/filter by rating.

    No big secret I suppose: it's RightMove.

    Really I think it should be forbidden in most circs to advertise a property without its energy label, and by extension I believe that it should be a filter criterion.

    I hope they've added it and I'm just too stupid to find it, but I suspect that they JustDontCare(TM).

    Rightmove aren't the estate agent. They do show EPC for many of the properties. The first had the EPC at the end of the description and the second had a link to EPCregister.com a Directgov websiten which gave me a .pdf of gobbledegook but also had a link to EPC advisor which apparently can give you hints on how to improve the rating of that particular home.

    That said it would be nice to have as a search option on right move and I think that would be worth campaigning for.

    I've been spending a lot of time trying to choose a new car at nextgreencar.com and something along those lines would be good.

    That might be a good thing. It's somewhat shocking that the word 'energy' doesn't even appear on the front page as far as I can tell.

    Exactly. The requirement is that the estate must have one available (actually, I think the requirement is that the appointment to get an EPC has been booked). Not much to do with Rightmove. And impossible to provide a search facility unless the agents were to correctly enter the numbers into a database. Which given their lack of ability to even list which rooms a house has consistently is probably not going to happen. Rightmove is so much better than anywhere else because of the drawn area search that I'd forgive them almost anything.

    Yeah, it was. Remember the conversation over a link you'd posted to a R4 prog and I said I particularly liked the expression.

    Today's You & Yours was interesting today. More or less saying what you've been banging on about for so long, that the price of energy will "have" to go up and then we all have choices to make...

    But they are as much use as a Chocolate Fireguard. When they did mine I asked if they were interested in the glazing units used and type of insulation etc and they said no - the software did not want this as a parameter! Utter waste of time IMHO.

    Just downloaded RDSAP 2009 from my Assessor site to check it out.

    Tried to enter my own property details: the RDSAP really is a useless piece of carp and in my opinion incapable of producing even an approximate EPC for a dwelling which has had any work done to it. I would not debase myself to use it on any of my Client's houses, I'll leave it to the estate agents which it seems to be targetted at.

    My biomass boiler which has a certified seasonal efficiency of 85% was not listed on the database and was then allocated a default efficiency of 63%.

    And yes the software is not interested in the actual U-value of my double glazing and the area of glazing is not measured but estimated by the assessor on a scale which includes 'typical' :shocked:

    rdSAP is the rating that is used to decide who is eligible for FITs, RHI, Green Deal ??
