Publication Open Access Investigating the role of Entropy in Design Evaluation Process: A Case Study on Municipality Buildings(2017-07) GÜZELCİ, ORKAN ZEYNEL; 187152The concept of entropy, which can be used to measure physical disorder, has been rediscovered by Shannon to measure the irregularity in information. Entropy measurements are made by considering one or more factors. Specific features such as color, shape, element type, height, material related with architectural compositions can be considered as factors and the amount of information carried by the building depending on one or more of these factors can be measured. In this study, it is questioned whether there is a relationship between entropy values of municipal building competition projects, which are measured in relation to the factors, and the building is considered successful by the competition jury. In order to conduct this examination, the entropy values of the projects, which respected to the same architectural program and won various awards in the project competitions were calculated. Before making comparisons, measurements were made according to solid-void ratios on the plan layout, the shapes of closed and discrete spaces, and the distribution of functions. A discussion was made on the usability of entropy method in the design phase, which gave solid and precise results according to the results of the comparisons.Publication Open Access Computational Interpretations of 2D Muqarnas Projections in 3D Form Finding(2016-11) Alaçam, Sema; GÜZELCİ, ORKAN ZEYNEL; 152924; 187152In the scope of this study, we developed an algorithm to generate new 3D geometry (interpretation) of a given or generated planar projection of a muqarnas in a digital 3D modelling software (Rhinoceros), its visual scripting environment (VSE) Grasshopper and also Python programming language. Different than the traditional methods, asymmetrical form alternatives are examined. In other words, 2D projections of muqarnas were only used as an initial geometrical pattern for generative form finding explorations. This study can be considered as an attempt to explore new relations, rules and vocabulary through algorithmic form finding experiments derived from 2D muqarnas projections.Publication Open Access An Experimental Study On Creating Process Of Geometric Patterns(2015-12) GÜZELCİ, ORKAN ZEYNEL; GÜZELCİ, HANDAN; 187152; 201115Artists and designers use geometric patterns to cover surfaces since ancient times. In the 13th century the architectural works show artists have a broad knowledge of creating geometric patterns. Mathematicians conduct researches and achieve creation principles of these patterns barely in the 20th century. In this context, the principles of patterns can be known by its designer but cannot be distinguished easily with a deductive approach. Geometric shapes that are typically repeating in order form a geometric pattern. Patterns are seen as an integrated composition of geometric shapes. Nowadays, computer-based programs help to create various patterns fast and efficiently. Mathematical operations are defined to make transformations on shapes. Executing simple transformations like moving, copying, mirroring and rotating on an initial shape creates 2D geometric patterns. The first objective of this study is to search the generation process of geometric patterns and find out which parameters are used to create these patterns. This study aims not only to create shapes or geometric pattern alternatives but also to teach generation principles of geometric patterns to design students experimentally by a generative code. In the scope of this study, 2D geometric patterns are studied which are analyzed by a deductive approach. According to analysis, the following parameters are used in generation process; Specification of initial shape / Position of initial shapes / Distance between repeated shapes / Number of the repetition of x and y-axis / Determination of the angle transformations By changing these parameters experimentally in coding interface, the transformation of patterns and variety in pattern geometry are examined. Before changing parameters, the main structure of code modified three times. At the first coding, hexagon shape is created by using simple lines. By copying hexagon ten times on “x” and “y” axis and moving one shape (hexagon) many different patterns are created. Besides, sub shapes are emerged in the pattern, which are not hexagons anymore. At the second coding, changing the edge number of initial shape is transformed hexagon into a pentagon. The angles between pentagons edges are modified, and pentagons become stars with different angles. These star geometries also rotate on the axis to generate different geometric patterns. During the third modification of code, hexagons edge number is set as a variable. Changing the edge number creates a pattern that includes lines, triangles, square, pentagon, hexagon and polygons with more edges than six. As a result of modified parameters like sizes, positions, edge numbers and angles many unpredictable patterns emerge. This study shows the efficiency of coding on pattern generation. Emerged shapes can be used again as an initial shape, and new patterns can be generated with a high variety.Publication Open Access Digitizing the Unexplored: Bridging the Concrete Experience and Abstract Geometry Through Physical Experiments(2016-04) Alaçam, Sema; GÜZELCİ, ORKAN ZEYNEL; 152924; 187152Ways of promoting creative approaches in the context of embedding digital design approaches in education are increasingly becoming a popular topic in architecture schools. On one hand, digital design methods, approaches and tools are diversified, while on the other hand, the danger for students losing control over the design process by appears as a new phenomenon. We argue that experiential dimensions of empirical observation conducted with physical experimentation might be helpful for students to comprehend digital topics creatively. With a particular emphasis on engagement of physical experimentation and computational thinking, this study aims to present a pedagogical model which has been applied from 2014 to 2016 within a postgraduate course. The potentials and limitations of the introduced pedagogical model are investigated through students' bottom-up and top-down algorithm development processes and the outcomes of the digital modelling exercises.Publication Restricted Design Tactics for Enhancing the Adaptability of Primary and Middle Schools to the New Needs of Postpandemic Reuse(Emerald Group Publishing Ltd., 2021) Sen Bayram, Asena Kumsal; Alaçam, Sema; GÜZELCİ, HANDAN; Akkuyu, Elif Işık; Sencan, İnanç; GÜZELCİ, ORKAN ZEYNELPurpose - The aim of this study is to present design tactics (DTs) for supporting the adaptability of existing primary and middle school buildings into the emerging needs of coronavirus disease 2019 (COVID-19). The study introduces a novel algorithmic model for postoccupancy evaluation of the existing school buildings and provides solutions to enhance the adaptability of these buildings. Design/methodology/approach - This study employs the DTs defined by the authors, integration of DTs to the algorithmic model and tests the usability of the proposed model in the selected sample set. The sample set consists of four primary and middle school buildings with different architectural qualities. The degrees of flexibility of the existing sample set are evaluated depending on the outcomes of the implementation. Findings - The degrees of flexibility are achieved as a result of execution of the algorithmic model for each selected school building. Initial results of the case studies show that the flexibility of a school building is highly related to affordances and design decisions of the plan layout which were considered in the initial phases of the design process. Architectural qualities such as open plan and having sufficient voids in the interior and exterior space become prominent factors for ensuring flexibility. Originality/value - Developing a systematic approach to the adaptation problem of primary and middle school buildings to postpandemic reuse is a novel research topic. Apart from this contextual originality, the proposed taxonomy for postpandemic reuse in terms of three levels of adaptation is a new conceptual framework. Moreover, the proposPublication Open Access Enhancing Flexibility of 2D Planar Materials By Applying Cut Patterns For Hands On Study Models(2016-11) Alaçam, Sema; Bacınoğlu, Zeynep; GÜZELCİ, ORKAN ZEYNEL; 187152; 152924Active experimentation during intertranslations between digital and physical modelling allow designers to explore new geometrical possibilities. Particularly, while changing the strength of the material, cut operations augment bending performance of the planar surfaces. Keeping in mind the potentiality of bending behavior as a generative tool for computational process, this paper presents the findings of three phased experimentation: implication of cut patterns to 2D planar material, mapping 2D patterns onto 3D surfaces and exploring new 3D free-form surfaces.Publication Embargo A proposal for personalized advanced traveler informatıon system(Istanbul Kultur Univ, Atakoy Campus, Bakirkoy, Istanbul, 34156, Turkey, 2015-10) GÜZELCİ, ORKAN ZEYNEL; 187152Nowadays, with technological developments and the popularization of mobile communication devices Advanced Traveler Information Systems become more popular for people who are traveling in the city. When Advanced Traveler Information Systems analyzed, in general, it is possible to see that systems produce monotype and not personalized route suggestions. These monotype routes ignore many parameters involved in the transportation process. Transportation activity has a complex structure that is affected by many physical and non-physical parameters varies from one to another. In the study, this complex structure is described through the transportation system of Istanbul. As a result of examination with a critical point of view, the necessity of a new Advanced Traveler Information System in Istanbul's Urban Transportation is highlighted. For more realistic route alternatives that consider all parameters and personal preferences affecting the transport infrastructure of the city, a conceptual framework of a new Advanced Transportation Information System developed.Publication Embargo Tree-Step Experimentation on Embedding Curvature to Rigid Planar materials Through Cut Patterns(2017-11) Alaçam, Sema; Bacınoğlu, Zeynep; GÜZELCİ, ORKAN ZEYNEL; 187152; 152924This study presents the outcomes and findings of a three-step experimentation to integrate analog and digital design and modeling techniques, with a particular focus on augmenting the affordance of bending behavior and curvilinearity of rigid planar surface materials. In the scope of the experimentation process, cardboard was used as a material, cutting and bending actions were utilized as techniques and laser cut and visual scripting environment were involved as tools. The potentials of subtractive material techniques such as cut, bend, kerf operations are examined. The experimentation covers hands-on pattern generation, embedment of cut patterns to 2D planar material, re-mapping 2D patterns onto 3D surfaces based on the insights gained in the previous phase and exploration of new 3D free-form surfaces both in physical and digital environments. The three-step experimentation model presented has potentials to contribute to the pedagogical studies focusing on explorative and creative approaches for integrative design formation and fabrication processes.Publication Embargo A Study on Measuring Complexity in Muqarnas Patterns(2019-04) Alaçam, Sema; GÜZELCİ, ORKAN ZEYNEL; 187152; 152924Throughout history, mathematicians from different cultures and places traced other scholars' work to make a contribution and extend the knowledge of the geometry field. In the Islamic world, artisans combine the theoretical knowledge about geometry and making skills to build more sophisticated and complicated geometric patterns. Today, the underlying principles of geometric patterns are still a research subject of many physicists and mathematicians. Geometric patterns are used both in design and construction phases of muqarnas which is a specialized spatial element in Islamic Architecture. In the scope of this study, after a comprehensive analysis, new muqarnas patterns are generated by using algorithms.Publication Embargo Kişiselleştirilmiş Bir Akıllı Ulaşım Bilgilendirme Sistem Önerisi(The Turkish Online Journal of Design Art and Communication, 2015-10) GÜZELCİ, ORKAN ZEYNELNowadays, with technological developments and the popularization of mobile communication devices Advanced Traveler Information Systems become more popular for people who are traveling in the city.
