    I am studying BEng(HONS) Architecture and Environmental engineering and am writing a dissertation on sustainabilty codes and regulations.

    I am looking for architects/engineers to fill out a quick questionaire regarding possible barriers to the design of highly sustainable new buildings from the UK's current codes and regulations.

    I would be very grateful if you could fill out the short questionaire below and return it as a comment to the discussion along with your job title. Any responses will be really helpful:


    Please indicate which of the following points, in your opinion are:

    A a significant hindrance to the design of successful sustainable new buildings
    B a possible hindrance to the design of successful sustainable new buildings
    C not a hindrance to the design of successful sustainable new buildings

    Possible hindrances:

    Contradictions between separate regulations, codes and assessment methods.

    The prescriptive style of regulations, codes and assessment methods (most notably code for sustainable homes).

    The stage of the design process at which buildings are first assessed (as a result of the way regulations, codes and assessment methods operate).

    A lack of understanding of sustainable design and technologies at higher levels.

    Statutory minimum standards not being exceeded (a lack of incentive).

    Non-statutory assessment methods.

    Confusion over a large number of regulations, codes and assessment methods.

    Tendency to ‘Green wash’ buildings to meet regulations, codes and assessment methods.

    The ability/tendency to compensate poor performance in certain areas with increased performance in others to achieve targets.

    THANK YOU FOR YOUR TIME

    I once asked our planning officer if I was more likely to get Planning Permission for a highly sustainable design. They said NO because ALL new buildings are considered sustainable - they don't give PP for unsustainable development.

    So...

    Contradictions between separate regulations, codes and assessment methods. = A

    The prescriptive style of regulations, codes and assessment methods (most notably code for sustainable homes). = B

    The stage of the design process at which buildings are first assessed (as a result of the way regulations, codes and assessment methods operate). = A

    A lack of understanding of sustainable design and technologies at higher levels. =A

    Statutory minimum standards not being exceeded (a lack of incentive). = A

    Non-statutory assessment methods. = A

    Confusion over a large number of regulations, codes and assessment methods. = B

    Tendency to ‘Green wash’ buildings to meet regulations, codes and assessment methods. = A

    The ability/tendency to compensate poor performance in certain areas with increased performance in others to achieve targets. = A


    I would also add that a lack of regulation of build quality is also an issue. For example how well insulation is fitted is as important as how much is fitted.

    Depends what you mean by "Sustainable". If you mean CSH level 5/6 then missing from the above list is cost: You can currently build a "sustainable" building for a far lower cost than by using the code. The code also defines "sustainability" rather differently from what you might mean by sustainability.

    So I would answer the question differently depending upon what you're trying to achieve by asking the question. I'd also say that you have quite a few missing factors depending on what the question is.

    Where was this planning officer from?

    Thinking about it, the title of the dissertation may be useful. I am investigating whether there is a gap in thinking between the policy makers and enforcers, and those designing buildings, and if so, is this hindrance to sustainable design. For the purpose of the investigation I am taking sustainability to mean highly efficient use of energy and water which affects a range of design elements from passive design to boiler specification.

    I guescost would be a good point; perhaps a gap in thinking between the two parties concerned would be a misjudgement on the part of the regulation designers, that a category 5/6, which are more ‘sustainable’ than lower levels but non-statutory will regularly be aspired to due to the additional cost. Also does following the code make highly ‘sustainable’ buildings as defined more expensive to create?

    Also what factors would you say are missing?

    There are exceedingly few real or proper sustainable new buildings so clearly there are massive problems.

    Another factor to consider is that land prices are way too high.

    If it's water and energy, then probably you need to consider if your definition of a "sustainable" home fits well with what policy makers think a "sustainable" home is: Less than 50% of the CSH design allocation is to these points.

    As bdp says, policy is to restrict the availability of land on which to build meaning that "sustainable" homes can only be built using a high density philosophy (best single use of land rather than best usage of land). This is related to the older guidance issued by the ODPM prior to the development of more current Government thinking on "sustainability" such as the Energy Bill and the Climate Change Bill.

    Because no-one can agree what "sustainability" means, there are a whole range of different competing interests vying to redefine the word. This leads to a lot of confusion on the part of developers and planning officers.

    CWatter's list is about right

    I would add

    1: No real definition of what "sustainability" is leading to confusion
    2: No real understanding at a local political level of what the government is trying to do
    3: The prohibitive cost of doing what the Government wants (which reduces the rate of replacement of existing stock and thus may well prove to contribute more to global warming than if the Code did not exist)
    4: At some level, the realisation in upper levels that the whole of the Code for Sustainable homes is, to an extent, "greenwash" in that it's not relatively important to produce "sustainable" buildings compared to the problem of pre-1945 housing stock (relative to your definition of "sustainability")

    Then there's the problem of regulation itself: There is a belief amongst some politicians that "sustainable" development can be steered and controlled by regulation. If a clear understanding of what they want to steer (the why) and of the potential technologies to do it (the how), this might have been a good idea. But there's little evidence that this is the case.

    The road to hell is paved with good intentions. I'm not sure I would have chosen such a difficult topic for a dissertation by the way. Just my opinion!

    No building is sustainable if in order to afford to buy it the occupier has to participate non a non sustainable economic model. I have to say that imvho the only sustainable housing happening in the UK atm is in the Low Impact Development movement, at least the LID people are addressing the relationship between people, economy, and environmental sustainablity.
