Green Star SA, Green Building Council rating

The Green Building Council of South Africa has set the following obectives for their GREEN STAR SA RATING TOOLS, this segment is extracted from their website:

1. Establish a common language and standard of measurement for green buildings
2. Promote integrated, whole-building design
3. Raise awareness of green building benefits
4. Recognise environmental leadership
5. Reduce the environmental impact of development

Looking at their objectives 1 and 2, we note the reference to common language and integrated whole-building design establishment. Fortunately these objectives are well supported by BIM and IFC.

Most good BIM systems now support the IFC standard, which unlike traditional methods of file translation between CAD systems, offers full data accessibility between BIM software platforms, ie. if one BIM package sees an element as a “steel IPE”, then so does the other BIM system, if they communicate via IFC. This is a very important link between these BIM platforms, as it allows both platforms to immediate “treat” the element in terms of its correct and intended definition. This becomes increasingly important, if we consider an application such as energy efficiency rating. Imagine a process between the architect who suggests a column is required, the structural engineer who specifies the exact detail of the column and the mechanical engineer, who has to calculate the heat transfer performance of the column in the context of the building project. Here the use of 3 true BIM platforms, that can communicate via IFC, will ensure that all 3 consultants can add value directly to each others input content, without any remodeling or confusing cross referencing.

This process would be enhanced in its accuracy, if verified by a model checker, to ensure that all parties could be satisfied that the content of the “greater BIM model” they are working on is constantly checked for accuracy and consistency.

    I find myself frequently in discussions around the legitimacy of BIM. “People” often wonder whether projects are truly 100% handled in true BIM and whether a true BIM implementation on a project infact has any benefit to a project.

    To answer such questions, I can offer a lot of theory usually, but most often I choose to refer to reality, as it is “PROOF” not theory.

    Here I often an example again of such reality:

    Ark by Rice Daubney is a current example of full BIM implementation, well worth analysing, more about the Ark project is available at:

    Related to green energy, not directly to building projects, is the National Treasuries DISCUSSION PAPER FOR PUBLIC COMMENT
    Reducing Greenhouse Gas Emissions:
    The Carbon Tax Option

    This is a fascinating document, released for public comment before end February 2011. Have your say and help guide our government in this important decision, read more at:

    Many people are working to solve the problems humanity faces today.
    According to my memory, it has taken us more than a decade to take note and accept the outcry of “those whacko greenies” to “change our ways because we are driving humanity towards extinction”.
    At last it feels like a general awareness of the severity of the dangers we face is common knowledge and is bringing about tangible change to the our daily lives.
    * CFC gasses are banned from manufacturing processes and consumables by legislation in almost every country today.
    * Deforestation is controlled to ensure the sustainable supply of raw materials AND hopefully contribute to reversing global warming or stabilizing the planet’s o-zone layer.
    * New technologies, building materials & -practices continually added to enhance the performance of buildings and achieve lower energy consumption.
    * This list can go on forever . . . . and yet not be complete.

    Will this change the way our buildings look and work? If you just look around a bit (globally that is) you will see that it already is. This video shows us just a glimpse of what really is possible “by studying the way nature solves problems” – and I like what I see. Michael highlights several leading projects that pushes the boundaries “beyond sustainable design, achieving restorative design” with “resources in closing loops”. Michael closes his talk with these exciting words: “let’s be positive and let’s make progress with the most exciting period of innovation we’ve ever seen.

    Through the technology of BIM, the “Design Industry” (Architecture, Engineering, Landscape, Interior, Manufacturing, Construction, Maintenance, etc.) has the opportunity to contribute so very much to the whole process. BIM as we know it today, simply is the best way to date to face the challenges this industry facing. And just like ourselves, BIM itself will also evolve through all our collaborative efforts.

    Much is being done but so many are still not involved.
    How long before 100% of the South African “Design Industry” joins in riding this wave that is about to change the face of this planet – I hope!
