Performance-based parametric design explorations: A method for generating appropriate building components

Performance-based parametric design explorations depend on formulating custom-designed workflows that require reading, writing, interpreting and manipulating databases, as part of the design process. The possibilities of customization and parameterization offered by the user-friendly interfaces of advanced building-performance simulation software and digital design tools have now enabled architects to carry out performance-based design explorations without the help of simulation experts. This paper presents a customized workflow methodology to explore design alternatives for producing shading devices that can optimize daylight, while blocking out excessive solar heat gains, in an office building in a hot and humid climate. The design alternatives were generated by evolutionary algorithms in accordance with daylight performance requirements and simulated to assess their shading and daylight efficiencies.


Parametric Urban Design Thinking: Shared Patterns in Design by Algorithm and Design by Drawing
Çalışkan, Olgu; Ongun, Gokhan (2021-12-01)
The paper suggests a focused examination of the processes of drafting-based design and parametric design in urbanism. It discusses how spatial design's settled cognition would differ by using algorithmic systems through the altered relationships between the basic operations in design. To reveal the commonalities and distinctions between the two design methods, the authors present the detailed documentation of the workshop series, which experimented with both techniques within similar design contexts. By the...
Layout optimization of trusses using simulated annealing
Hasançebi, Oğuzhan (2000-09-08)
This paper addresses to the development of a simulated annealing (SA) based solution algorithm which is automated to achieve the simultaneous optimum design of truss type structures with respect to size, shape and topology design variables. The proposed algorithm is designed in such a way that together with applicability to practical design problems, it is also aimed at producing efficient and improved design solutions for the problems of interest. From the practicality point of view, the task is chosen as ...
Creative Design Exploration By Parametric Generative Systems In Architecture
Gürsel Dino, İpek (Middle East Technical University, Faculty of Architecture, 2012-01-01)
This paper discusses parametric design systems as a generative tool in architectural design. Parametric tools are algorithmically based, and therefore offer increased computational control over design geometry during design activity. Their adaptability and responsiveness to changing design criteria and requirements make parametric models especially useful for design exploration in complex and dynamic design settings. In performance based design, parametric control of form is particularly valuable, such that...
Visual Structuring for Generative Design Search Spaces
Abbas, Günsu Merin; Gürsel Dino, İpek (2016-06-17)
With generative design strategies, the act of design, the problem-solving process, and the interaction, understanding and representation of design artefacts have changed. As such strategies entail a large number of possible design solutions, they also expand the design search space immensely. In addition, due to the automated design generation process, the interaction of the designer through the design process has decreased. This research problematizes two major points as (1) the broad design spaces of gene...
Parametric Design in Urbanism: A Critical Reflection
Çalışkan, Olgu (2017-01-01)
Parametric modelling run by the explicitly defined algorithms generating synchronically auditable dynamic forms and patterns, has become a prominent method especially in architecture. Though the use of parametric models has got wider in urban design, the critical reflection on the actual and possible application of the method in urbanism has fallen limited so far. The paper tends to relate parametric design with the contemporary understanding of urbanism with regards to the idea of design control in the the...
