Jan 2012: Building Information Modelling creates more sustainable buildings.
Building Information Modelling (BIM) is a three-dimensional computer modelling tool that encompasses building geometry, spatial relationships, geographic information and quantities. Unlike most two and three dimensional design software, BIM gives its objects more than just dimensions. For example, attached to a door created using BIM will be details such as the material it is manufactured from, which direction it opens in, the hardware attached to it, its maintenance requirements etc.
In addition, BIM can extend far beyond building design to address tasks such as cost management, project management and even asset management, which is one reason why the UK government is so keen for the construction industry to adopt it.
A big advantage of BIM in the design phase of a project is that it provides immediate feedback on design alternatives early in the process. Many digital building models contain too little information for detailed building performance analysis and evaluation. However, BIM represents the building as an integrated database of co-ordinated information by linking the model to analysis software. This means that building owners can examine the implications of design decisions, such as the effect of orientation on the building’s energy consumption, to optimise its design. BIM lets designers study multiple “what if” options simultaneously within a single model.
The information available from BIM and ‘in use’ intelligence, from the building management system and such like, will demonstrate whether performance targets are being met in terms of carbon emissions and embodied carbon – and whether the building is performing as expected
