Classification of building elements

In the Netherlands the 'Elementenmethode' is used for the classification of building elements. This method, based on the Swedish SfB, is developed into an object orientated classification, used for ordering building objects in e.g. CAD-systems, building estimations and documentation of related information. Although widely spread and used in the Netherlands as is, the method will become 'under construction' in order to include new developments and regulations concerning classification and to make it completely suitable to automation tasks. The responsible organization, the Royal Institute of Dutch Architects, BNA, did put this method on the Web, in order to enable all parties to contribute their comments and suggestions, which will be used for the new version.

This English page doesn't reflect the entire method: the general list of elements is given as well as a typical example. An element is subdivided in variants (see also the example).
