    The Regs: Eurocodes

    18 March, 2010 | By Geoff Wilkinson

    "For those who haven’t been following the story, it dates back to 1975, when the European Commission decided it would eliminate technical obstacles to trade and establish a set of harmonised technical rules.

    In 1989, CEN (the European Committee for Standardization) set about the preparation and publication of the Eurocodes as European standards. CEN has prepared a huge suite of structural Eurocodes comprising 58 parts covering basis of design, loading, the major construction materials, geotechnics and design in earthquake areas.

    Under the agreement with CEN, the national standard bodies will withdraw conflicting national standards in March 2010. Practically, this means that from 1 April 2010, the national codes of practice for the design of buildings in the UK will be the Eurocodes.

    Meanwhile, David Sharpe, associate at engineering consultancy Pell Frischmann, said: ‘The costs and decrease in efficiency are significant for SMEs. All of our structural software needs to be relevant to the Eurocodes. All of our technical staff need to combine formal CPD with on-the-job training, to learn how to apply the new codes to current designs.’

    I wrote: "Yes, we all know about Eurocodes. But the local building code in the UK is called "Building Regulations" and it is most certainly not withdrawn. Neither is the code in Germany, which operates on very different principles AIUI. Building codes are legal frameworks, not technical standards."

    And bot de paille responded: "Sorry djh but that is just not correct. You are confused like many because they are still called building regs and not Eurocodes."

    Well, I know you are incorrect. So we're just going to have to agree to disagree about this issue. :devil: :cool:

    Here are pointers to the building regulations

    and here is a page that clearly indicates the position of Eurocodes as [just] one part of the regulatory guidance

    Thats it!!!! I'm voting UKIP and building with strawbale:devil:

    Just joking lads

    If UKIP got in you would be at the mercy of large landowners for your straw. :wink:

    ??? I dont understand, whats the joke?

    All the EU interference that is going to save us from ourselves :rolling:
    There is a live webinar presentation on the 29th January for Ecodesigner Star for Archicad. This promises to be an interesting presentation and discussion for anyone who wants to find out what BIM can do for sustainable design. I have already signed up and based on previous webinars, would recommend it to anyone else. I'm sure it will be informative and help give a good idea of what all the fuss is about. Normally there is also the chance to pose questions at the end.

    Personnaly, Im looking to see confirmation that it will be possible to export directly to PHPP xml spreadsheet, something that was possible with earlier versions of Ecodesigner.


    This live online seminar will present GRAPHISOFT's brand new EcoDesigner Star building energy modeling solution.

    EcoDesigner Star enables architects to use ArchiCAD's building information model (BIM) directly as a building energy model (BEM). This ensures streamlined collaboration between designers and energy consultants. Furthermore, EcoDesigner Star offers standard-compliant energy analyses on the BEM and produces a detailed building performance report, all within the familiar ArchiCAD design environment.

    We will present the M Labs research center, designed by Eurobuild, a company specializing in the design of low energy buildings. Eurobuild was one of the first design teams to utilize the easy-to-use, accurate, and streamlined EcoDesigner Star energy analysis workflow to generate reliable building energy evaluation on the M Labs project, at every stage of the design workflow.

    Anyone interested in BIM software design and BEM (building energy modelling) might want to check out this video presentation of Ecodesigner Star. It gives a good explanation of what BIM and BEM are and presents a project that was built in the UK, Eurobuilds M Soft research centre in Kent. Eurobuild used the software during the design.

    Of note, Ecodesigner exports to PHPP,can carry out thermal bridging calculations from detail drawings (3mins40sec), and can do direct solar irradiation and shading analysis for any opening (27min 30sec).
    Have people seen this?: http://www.passitherm.com/psi-therm/

    The Psi-Therm 3D in particular looks interesting, I'm wondering if it's as good as it looks...

    Where did that come from? Some back bedroom in Scotland? Any good?

    Having talked to ANSYS people recently, 3D (as opposed to 2D like Therm) heat flow is a major computing task, and costs £7000-plus from them, for stripped-down version without fluid/airflow.

    However, they were confident (in principle, not having tried it) that it would cope with interseasonal heat storage into uninsulated ground! But then, that's what people have managed to get Tas to do, but EDSL, Tas' supplier, disown the results as unverified use of their physics model.

    Psi-Therm...set themselves apart from the competition by providing the user with ease of use and quick performance speeds.

    Sounds like my kind of software. Why do they all develop exclusively for Windows though??

    Because other platforms are rubbish, especially anything with Mountain Lion (suitable for a cougar) on it, only good for painting by numbers. :bigsmile:

    I have to agree with them :)

    It's perhaps not 100% relevent but I saw a really impressive demo of Sketch Up plug in for PHPP at the AECB conference (sorry if it's been mentioned elsewhere). Definitely encourages me to get to grips with Sketch Up - at the moment my 12 year old is far better at SU than I am.

    Any idea when this plugin will be released? They've been hinting at it for at least a year and I'm still holding out to see a demo as the clincher on whether to buy PHPP and teach myself...

    It says it is set to be released summer 2013 i.e. nowish.

    Automatic recognition of temperature zones, element types and area groups
    Schedules of areas, windows / doors and TFA components and recognition of external shading objects
    Rendering of heat-loss areas to indicate their area group or status
    Export geometry and shading data to PHPP via PPP file format, with conversion of elements to meaningful dimensions and quantities that can be manipulated in PHPP
    Tools to insert and edit window & door components, with user-defined properties or from standard libraries
    Simple energy balance within the tool and warnings about high-levels of glazing that would lead to overheating
