    Does anyone have an opinion on the Code for Sustainable Homes document released by the government in December?

    Do you think it will encourage the growth of sustainable housing?

    Mark Brinkley seems to think otherwise.
    Are you sure?

    Hi Nanuls,
    I work for several developers and they all seem to be gearing up for Code level 3 as a way of getting planning permissions, some clients are also asking for level 4 and one is enquiring about level 5!
    Just need to iron out a couple of probs with the software that has been issued, currently very difficult to source products that will meet Code level 3 water usage.
    Think the Code is here to stay and can only be a good thing provided it is phased in level by level and not jumped to level 6.
    Thinking about, I think the answer is both yes and no. Yes, the Code will be an effective tool. And actually setting it at 6 levels is a good idea, because it naturally gives people targets to aim at. And Level 6, the top level, is really exacting by anybodies' standards.

    But on another level, there is a paradox which the Code doesn't really address. Can new housing ever really be 'sustainable'? The problem isn't with the word 'sustainable', it's with the word 'growth'. All new development adds to the stress on the environment, however you chose to look at it. Making it 'sustainable' only really reduces the amount of added stress.
    Hi, I am interested to know whether 2 of the Code levels are roughly equivalent to the AECB gold/silver standrds?
    If so which levels? I seem to remeber reading something about this on another thread
    * AECB Silver levels of energy performance (CSH Level 4), giving 70% savings in CO2 and 75% in primary energy - compared to the average stock equivalent
    * AECB Gold levels of energy performance (CSH Level 6) giving 95% savings in CO2 and 85% in primary energy

    The AECB are holding an Early adopters' workshop 10th may, Milton Keynes. They will be examining the standards and there relationship with the CSH.

    Is there a code for refurbishment of existing houses? This is more my area of interest and it would be handy to have a benchmark or something to work towards.
    Why not refer to the AECB Silver and Gold standards? They will certainly get you on the right path for reducing your carbon emissions, and given that addressing domestic hot water consumption is a part of that process, you'll end up with water conservation measures to boot.

    Do you think the AECB standards will endure now that the CSH has been produced?
    I think that the AECB standards dovetail in quite well with the CSH as it acts like a form of Part L. I believe that by having a prescriptive standard as a referance point it will help to avoid the re-inventing the wheel for each and every project by each and every developer/design team. Admittedly the AECB standards are not a "final" answer in the grander scheme of all things sustainable (they don't cover certain issues covered by the CSH, and the CSH isn't perfect) but it could be understood to be a major part of it. In a nutshell I believe that the Silver and Gold standards are good staging posts for energy consumption when proceding along the route to Level 6.

    Thanks for all your help I'm very grateful, does anyone know if the Code is applicable to Wales, Scotland and Northern Ireland?

    No - it is just for England and I expect that Scotland, Wales and Northern Ireland will want to do something different just to show that they are different. That is a bit unfair to Scotland as their Building Regulations are quite different to England and Wales, but Northern Ireland are pretty much the same as E&W.

    There is a BRE EcoHomes XB which is for existing stock. Don't think it will change into a Government code.

    Full details on Code Levels and all the technical stuff is in the 200 page Technical Guide that you can download from the Planning Portal. http://www.planningportal.gov.uk/england/professionals/en/1115314116927.html

    Does anyone think that the legislation will be of particular relevance to certain sectors, e.g. affordable housing?

    Not many benny, H/A's will lap up the Code, infact they won't get any funding in 2008 if they don't.
