summary This article proposes to study the process of parametric design integrated analysis and structural design. This application model is called Performative Model; the form is generated based on performance criteria. The digital tools facilitate the information flow between designers using parametric model and Finite Element Analysis. To research the method of Performative Model is proposed the development of a conceptual framework of lattice wind tower with the aim of a quantitative and qualitative structure optimization. Therefore, the parametric modeling will be done using Rhinoceros software, the plugin for creating algorithms Grasshoper and structural analysis plugin Scan & Solve.

summary Traditionally media facades have been created using 2D surfaces, not dissimilar to televisions. As computational architecture continues to explore non-Euclidian shapes it is a logical process to investigate the use and possibilities of emerging complex curved surfaces for the display of media content to match architectural design aspirations with demands of ubiquitous city concepts of penetrating surfaces with information. Drawing on existing architectural knowledge of ruled surfaces the paper outlines the implementation of adopting existing principles from architecture and mathematics to contemporary discussions in media architecture. It demonstrates that ruled surfaces can function as media facades by simulating ten different ruled surface types in Grasshopper and overlaying them with different video content. Based on the results the team proceeded to build a 1:1 prototype of a hyperbolic paraboloid to test if the simulated results in the computer matched with the physical model. The prototype was further tested using media content to observe the visibility of the display from various viewing positions. Based on the findings the paper concludes that ruled surface media facades are feasible. This investigation, its proposed hypothesis, methodology, implications, significance and evaluation are presented in the paper.

summary Building energy performance assessments are complex multi-criteria problems. Appropriate tools that can help designers explore design alternatives and assess the energy performance for choosing the most appropriate alternative are in high demand. In this paper, we present a newly developed integrated parametric Building Information Modeling (BIM)-based system to interact with cloud-based whole building energy performance simulation and daylighting tools to optimize building energy performance using a Multi-Objective Optimization (MOO) algorithm. This system enables designers to explore design alternatives using a visual programming interface, while assessing the energy performance of the design models to search for the most appropriate design. A case study of minimizing the energy use while maximizing the appropriate daylighting level of a residential building is provided to showcase the utility of the system and its workflow.

title A Model for Land Use Distribution Forecasting: To evaluate and negotiate with design scenarios
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 3853-394
summary In designing and managing land use distribution, as a complex system, in addition to providing a visionary and intuitive strategy one should consider the rule based optimization processes and the internal autonomous forces. These ensure cities global eligibility besides their local efficiency and compatibility. This essay suggests a model to create negotiation between these two approaches. The tool is developed as an agent based model in a parametric environment and presented through a hypothetical case study. First, the system structure and behavior is defined and then through direct and indirect control tools, challenge was to achieve suggested design scenario without ignoring the self organizing behavior of agents.

title Approximating Computational Fluid Dynamics for Generative Tall Building Design
source International Journal of Architectural Computing vol. 12 - no. 2, 155-178
summary Background literature review, methodology, results, and analysis are presented for a novel approach to approximating wind pressure on tall buildings for the application of generative design exploration and optimisation.The predictions are approximations of time-averaged computational fluid dynamics (CFD) data with the aim of maintaining simulation accuracy but with improved speed.This is achieved through the use of a back-propagation artificial neural network (ANN) with vertex-based shape features as input and pressure as output.The training set consists of 600 procedurally generated tall building models, and the test set of 10 real building models; for all models in both sets, a feature vector is calculated for every vertex. Over the test set, mean absolute errors against the basis CFD are 1.99–4.44% (_:2.10–5.09%) with an on-line process time of 14.72–809.98s (0.028s/sample). Studies are also included on feature sensitivity, training set size, and comparison of CFD against prediction times. Results indicate that prediction time is only dependent on the number of test model vertices, and is therefore invariant to basis CFD time.

summary Despite reservations for the rule-based perspective of design with regards to creativity, the role and the potential of rules is instrumental in reflective design thinking. Rules enable sensible and functional conversations about the process. Working with (and mastering) a small rule set is common amongst artists as well. Escher developed rules based on the shape combinations in Majolica tiles to investigate regular plane divisions in his own work. Dwelling on a rule set allows for explorations in a rich design space that result in new series of works. Escher’s published sketches show that throughout his artworks, keenness in seeing shape relations and an ability in manipulating simple shape rules leads to numerous artworks from the same tessellations. Through a visual and rule-based analysis of artistic tiling in Escher’s work, the paper provides a computational perspective on analytical methods for design.

summary This work explores the possible use of the shape grammar formalism in generating small/medium sized dwellings or shelters as a possible and effective solution for shelter shortages that usually follows in the wake of a natural disaster. The shelters are generated using a set of pre-fabricated elements that add up to form a coherent and functional dwelling. The grammar exemplified here, being a shape grammar, deals specially with generating the underlying functional diagram and the floor plan of one possible solution based on a set of typologies design a priori.

title Integrated Generative Technique for Interactive Design of Brickworks

summary Bricks have been used in the construction industry as a building medium for millennia. Distinct patterns of bricks depict the unique aesthetic intentions found in Roman, Gothic and Islamic architecture. In contemporary practice, the use of digital tools in design has enabled methodologies for creating new forms in architecture. CAD and BIM systems provide new opportunities for designers to create parametric objects for building form generation. In masonry design, there exists an inherent contradiction between traditional patterns in brick design, which are formal and prescribed, and the potential for new patterns generated using design scripting. In addition, current tools do not provide interactive techniques for the design of brickwork patterns that can manage constant changes parametrically, to inform and influence design process, by providing design feedback on the constructive and structural aspects of the proposed brick pattern and geometry. This research looks into the parametric techniques that can be applied to create different kinds of patterns on brick walls. It discusses a methodology for an interactive brickwork design within generative techniques. By integrating data between two computational platforms – the first based on image analysis and the second on parametric modeling, we demonstrate a methodology and application that can generate interactive arbitrary patterns and map it to the brick wall in real-time.

summary In continuation to the Deceptive Landscape Installation research project (Agkathidis, Kocatürk 2014), this paper investigates the implementation of generative design techniques in undergraduate architectural design education. After reviewing the main definitions of generative design synoptically, we have assessed the application of a modified generative method on a final year, undergraduate design studio, in order to evaluate its potential and its suitability within the framework of a research led design studio, leading to an RIBA accredited Part I degree. Our research findings based on analysis of the design outputs, student performance, external examiners reports as well as student course evaluation surveys indicate a positive outcome on the studio's design approach, as well as its suitability for an undergraduate design studio. They initiate a flourishing debate about accomplishments and failures of a design methodology, which still remains alien to many undergraduate curricula.

summary Innovative design approaches are needed for mass housing implementations. Especially increasing interaction between user and designer is major important in the design decisions of these buildings. For this, it is seriously necessary to benefit from technological advances in computational designs, because digital tools like shape grammar, cellular automata, genetic algorithm, l-systems and agent-based models in this field provide not only to save time and to manage the relationships but also to generate many different alternatives. Accordingly, a digital support tool for designers has been developed by using cellular automata approach and scripts of 3Ds Max software. It produces samples of housing design plans which is generated by cellular automata approach according to the data of users' preferences. In this paper the interface and contributions of the developed model are introduced and discussed.

title Experimenting with CAAD: As a means to solve conceptual design by architecture and architecture technology students
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 227-239
summary This study sought to characterise students’ design activity while designing with Computer Aided Design (CAAD) professional programs and its impact on the students’ design process. The design protocol participants were final year students (architectural design and architectural technology), who have spent at least four years in a school of architecture and were confident CAAD users. The analysis represents four CAAD-based protocols of final year students at a school of architecture. The analysed protocols varied in more than one aspect. This variation includes: (1) programs, (2) the mode of using programs whether single or multiple, (3) protocol segments (total number, duration and frequencies), and (4) design categories and total time spent in designing. In light of the study results, the participants demonstrated that, for the same design problem, restraining the conceptual design medium would not necessarily bind them to a certain design strategy. However, there are some disciplinary differences between AD and AT final year students, on how CAAD is used during to solve conceptual design.

summary Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

summary Surrogate models (SM) present an opportunity for rapid assessment of a building's performance, surpassing the pace of simulation-based methods. Setting up a simulation for a single concept involves defining numerous parameters, disrupting the architect's creative flow due to extended simulation run times. Therefore, this research explores integrating building energy analysis with advanced machine learning techniques to predict heating and cooling loads (KWh/m2) for single and multi-zones in buildings. To generate the dataset, the study adopts a parametric generative workflow, building upon Chou and Bui's (2014) methodology. This dataset encompasses multiple building forms, each with unique topological connections and attributes, ensuring a thorough analysis across varied building scenarios. These scenarios undergo thermal simulation to generate data for machine learning analysis. The study primarily utilizes Random Forest (RF) as a new technique to estimate the heating and cooling loads in buildings, a critical factor in building energy efficiency. Following that, A random search approach is utilized to optimize the hyperparameters, enhancing the robustness and accuracy of the machine learning models employed later in the research. The RF algorithms demonstrate high performance in predicting heating and cooling loads (KWh/m2), contributing to enhanced building energy efficiency. The study underscores the potential of machine learning in optimizing building designs for energy efficiency.

summary Model checking is one of the core methodologies of Building Information Modelling (BIM). It allows us to quickly evaluate models based on custom criteria. While there are known examples of the integration of model checking into the course content of design studios, there is no literature on utilizing this methodology to help in the grading process of BIM software courses. This paper presents a project that applies model checking to the task of rating the learning success of students in such a course. The main project goals were increasing the objectivity of the ratings and reducing the time necessary to process a large number of submitted models. The paper describes a possible approach to categorizing and organizing model checks in an educational context and outlines a proven and tested workflow for automating the rating and feedback process.
