1. Purpose
In the various manufacturing fields including the building field, the form design is devised by the designer. However, the designer's idea range depends on his personal background such as education or environment, so it has been pointed out that his design idea is controlled by his background. The facade of the building controls the visitor's impression, so the image of the design is very important. Various studies such as the constitutions or histories of the facade are performed, but the facade design support system has not been developed. Therefore, if there is an idea generation support system which is defeating a conventional idea of the designer and expresses the detail of the facade, it would be effective. The purpose of this study is to develop the idea generation support system giving “discovery” to the designer for the facade design of an office building. The purpose of the previous research was to verify the difference in the evaluation number of individuals of IDE. This study analyzes the form elements constituting a facade and proposes new algorithm IDES based on IDE, in order to create many various design forms efficiently. The multiplicity of design by IDES and the effectiveness of the system are verified in comparison with those by IDE.
2. Methods
58 form elements are extracted by collecting and classifying the image of an existing office building. 58 form elements are replaced to the individual's vector of IDE and IDES, and became incorporated into IDE and IDES algorithms. 3D images of facades by IDE and IDES algorithms are expressed by VRML. The verification of this system was performed by 20 students learning architecture.
3. Conclusions
In IDES, 80% of all creations were created as different designs without duplicate compared with the IDE. IDES is effective algorithm as design idea support system, because the “very good” design was created about 2 times compared with the IDE. The classification of form elements extracted in the previous research is proper, because the facade designs created by this system are realistic and diverse.
