"Parametric modelling techniques for EeB: Semantic Web PMO format that shows the parametric extension of IFC towards storage of the parametric knowledge in an open format. There is a close relation with the configurator of parametric solutions developed in WP6."

A general issue for STREAMER is that no existing BIM tool supports a standard for importing and exporting parametric BIM models. The IFC standard, being supported by all major BIM tools and used as central format for exchanging BIM data in STREAMER, is not able to represent advanced parametric models. The development of "Parametric IFC" has started (see chapter 2), but is still in a state where it is neither supported by any existing BIM tool nor can be used for one of the design tools prototypically developed in STREAMER WP6. Thus, the usage of traditional parametric modelling techniques and tools in STREAMER is limited.

The intended goal of this deliverable is to support the EDC to translate a Programme of Requirements (PoR), into a spatial arrangement. This is the main function of the EDC. The EDC demands a set of general design rules which represent the "tacit knowledge" of design experts to be able to translate a PoR into design proposals. These design rules are imported into the EDC.

For reasons mentioned above, the scope of this deliverable has been extended with the development of design rules. The deliverable will thus focus on the current state-of-art in parametric modelling, the possibilities of using parametric modelling in STREAMER, AND design rules.
