CAADFutures 2015 - Shape grammars for architectural design: the need for reframing
Download as PPTX, PDF6 likes2,034 views
The document discusses the role of shape grammars in architectural design and the potential for computer implementation to aid in this process. It emphasizes the need for reframing the design space to improve the effectiveness of shape grammars and presents two approaches: using them as analytical grammars or as original grammars. The authors analyze existing systems and their implementations, advocating for a qualitative evaluation of shape grammar interpreters in design support.
CAADFutures 2015 - Shape grammars for architectural design: the need for reframing
- 1. Shape Grammars for Architectural Design: The Need for Reframing Pieter Pauwels, Ghent University Tiemen Strobbe, Ghent University Sara Eloy, ISCTE - Lisbon University Institute Ronald De Meyer, Ghent University 1
- 4. The designer as a reflective practitioner – D. Schön, 1983 the architectural design process 4
- 5. information / experience The designer as a reflective practitioner – D. Schön, 1983 the architectural design process 5
- 6. information / experience The designer as a reflective practitioner – D. Schön, 1983 the architectural design process build up of design grammar (known / trusted patterns) 6
- 7. information / experience The designer as a reflective practitioner – D. Schön, 1983 the architectural design process build up of design grammar (known / trusted patterns) What if we put the patterns of this grammar in a database in a computer and let that computer use it? 7
- 8. ice ray lattice grammar Palladian grammar Terry Knight grammar Koch snowflake grammar shape grammars – geometry/syntax 8
- 9. shape grammars – meaning/semantics 9 Malagueira house grammar FLW grammar
- 10. conceptual differences geometry meaning • geometric rewrite rules • ambiguous • emergence • ‘easy’ to implement • little to no help for an architectural designer • semantic (graph) rewrite rules IF{‘left’} THEN {…} IF{‘right’} THEN {…} IF{‘street side’} THEN {…} IF{‘ courtyard’} THEN {…} • unambiguous • emergence? • ‘harder’ to implement • does it help the architect? 10
- 11. So, how to use implemented shape grammar interpreters for architectural design support? the question for this presentation 11 In a broad sense. There are many flavours here.
- 12. the method - literature study - What systems have been implemented - Which uses were targeted by those systems - analysis of our own implemented shape grammar interpreter + our experiences in implementing and using it ==> qualitative evaluation by comparison 12
- 14. a computer-implemented shape grammar: design paths in a design space Finite set of shape rules R 14
- 15. shape rules R root design state I design paths visual representation graph representation 15
- 16. shape rules R graph rewrite rules: IF { GRAPH } THEN { NEW GRAPH } 16

- 18. THE NEED FOR REFRAMING 18
- 19. information / experience the presence of shape grammars in the architectural design process build up of design grammar (known / trusted patterns) 19

- 21. 21 traversal through design space The design space is defined by the shape rules and the initial design state
- 22. information / experience at computer run-time build up of design grammar (known / trusted patterns) 22 shape rules R following a design path FIXED design state
- 23. 23 changing design space => PROBLEM: THERE IS NO WAY TO GO BEYOND / CHANGE THE INITIALLY DEFINED DESIGN SPACE

- 27. CONCLUSION: TWO IMPLEMENTATION AND USAGE APPROACHES 27
- 28. information / experience option 1: implemented shape grammars to be used as ANALYTICAL grammars build up of design grammar (known / trusted patterns) 28 shape rules R following a design path FIXED design state
