summary The optimisation of semi-transparent building integrated photovoltaic facades can be challenging when finding an overall balanced performance between conflicting performance criteria. This paper proposes a design optimisation method that maximises overall energy savings generated by these types of facades by simulating the combined impact of electricity generation, cooling load, and daylight autonomy. A proof-of-concept demonstration of the proposed method is presented for a typical office facade.

summary Designers interested in applying evo-devo-design methods for performance based multi-objective design exploration have typically faced two main hurdles: it’s too hard and too slow. An evo-devo-design method is proposed that effectively overcomes the hurdles of skill and speed by leveraging two key technologies: computational workflows and cloud computing. In order to tackle the skills hurdle, Workflow Systems are used that allow users to define computational workflows using visual programming techniques. In order to tackle the speed hurdle, cloud computing infrastructures are used in order to allow the evolutionary process to be parallelized. We refer to the proposed method as Evo-Devo In The Sky (EDITS). This paper gives an overview of both the EDITS method and the implementation of a software environment supporting the EDITS method. Finally, a case-study is presented of the application of the EDITS method.

title Prototyping of an Adaptive Structure based on Physical Conditions
source International Journal of Architectural Computing vol. 11 - no. 2, 205-226
summary Latest advances in digital architectural design enable applications of computation and fabrication strategies for the development of adaptive mechanisms. Adaptive design processes, influenced by environmental and human related conditions, are only developed partially with regard to the design, fabrication, and multi-objective performance based context. The current paper proposes an adaptive design process that investigates the design of a kinetic structure emphasizing material behaviour, embedded technology and computation. In parallel, it allows design proposals to adapt or transform with regard to geometrical configuration and structural behaviour according to external and internal influences. An adaptive hybrid structure is developed at digital and physical prototype level, where its behaviour is examined in real time under the influence of physical conditions. The development is based on a holistic design approach driven by environmental and human activity related conditions, while focusing on the application of elastic materials and embedded technology.

title Programming In The Model — A New Scripting Interface for Parametric CAD Systems

summary Programming, often called scripting, has become a key feature in most CAD systems and an equally key area of expertise in CAD. However, programming surrenders many of the benefits of direct manipulation and introduces notational elements that are cognitively distant from the designs being created. In addition, it creates barriers to use and is often perceived as being too difficult to apply. We introduce Programming In the Model (PIM) through a prototype, implementing live side-by-side views, multi-view brushing and highlighting, live scripting, auto- translating from modeling operations to script and localized relational information within model windows. A qualitative user study confirms PIM’s features and raises issues for future development. A key result is the need for multi-directional extreme liveness , that is, maintaining consistency of action across views at the smallest possible scale. We argue that PIM principles are applicable in textual and visual programming alike.

title Working with Multi-scale Material Distributions

summary At present, computer aided design (CAD) software has proven ill equipped to manage the spatial variations in material properties. Most digital design packages employ a surface modeling paradigm where a solid object is that which is enclosed by a set of boundaries (known as boundary representations or “B-rep” for short). In surface models, material representations are often treated as homogenous and discrete. Yet, natural materials are capable of structures where the variability of material within a volume is defined at a multiplicity of scales and according to various functional criteria. With the advent of new 3D printing techniques, a new possibility emerges—allowing new multi-material composite objects to be fabricated in a single build volume with a high degree of dimensional accuracy and repeatability. However, a big limitation facing complex high resolution digital fabrication comes from the software’s inability to represent or handle material variability. This paper proposes a new digital interface for working with multi-material distributions at a variety of scales using a rasterization process. Beyond the immediate benefit of precise graduated control over the material distribution within a 3D printed volume, our interface opens new creative opportunities by enabling the use of existing image processing techniques (such as filtering, mapping, etc.) which can be applied to three-dimensional voxel fields. Examples are provided which explore the potential of multi-scale material distributions.

title Multi-Objective Heuristic Computation Applied To Architectural And Structural Design: A Review
source International Journal of Architectural Computing vol. 11 - no. 4, 363-392
summary Heuristic computation techniques have been used in a wide range of fields, demonstrating their capacity to solve highly complex optimization problems. This article presents the most common techniques and their extension into the multi-objective optimization field, and emphasizes in the application of them in structural and architectural design by presenting examples within topics like: topological, shape and dimensional optimization of truss structures, roof optimization for sunlight conditions and area minimization, grid structures, façade design, life cycle cost and environmental impact, energy efficiency and construction costs, morphogenetic structural optimization for shell structures, acoustical optimization, evolutionary architectural design, architectural layout design optimization, RC frames optimization, and land use zoning, within others. Finally, the conclusion leads to the recognition of heuristic computation not only as an optimization tool, but also as an important component of a design methodology for creating innovative, creative, efficient, well performing, and aesthetically pleasant architectural/engineering objects.

Internal and external stimulus from users and the environment guide, trigger and inform encoded decisions throught the spectrum of scales. The design of seamlessly embedded correlated networks of heterogeneous performative systems enablingsensoring, processing and actuation provides connectivity and redundancy through the ability to accommodate for synchronized and continuous real time reconfiguration and adaptation.

title Techniques for More Productive Genetic Design: Exploration With GAs Using Non-Destructive Dynamic Populations
source ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 227-234
doi https://doi.org/10.52842/conf.acadia.2013.227
summary The products of generative design are ever more commonly explored and refined through evolutionary search techniques. Genetic algorithms (GAs) belong to this class of stochastic procedures, and are particularly well-suited to the way designers investigate a problem. GAs search by mixing and matching different parts of a solution, represented as parametric variables, to find new solutions that outperform their predecessors. Generally the method proceeds through generations of populations in which the better solutions out-survive their less desirable siblings. Inherent to this approach, however, is the fact that all but the select solutions perish. This paper discusses a non-destructive GA that uses dynamic populations drawn from a bottomless pool of solutions to find the most productive breeding pairs. In a typical GA the survival or destruction of a solution depends on a well-defined fitness function. By not enforcing the destruction of less fit individuals, the possibility is held open to modify the fitness function at any time, and allow different parts of the solution space to be explored. This ability is ideal for more complex multi-objective problems that are not easily described by a single fitness function. Generally, design presents just such a problem.

summary The BIM software (Building Information Modeling) enables a holistic model -a complete description of the model-building for a complete analysis and validation prior to build, as well as the plotting of final design in architecture and its subsequent maintenance. Users can extend virtually unlimited capabilities. For this reason we have chosen a BIM with programmability by the user to create a calculation module to validate, the heat transfer and possible condensation on both walls and ceilings. The Revit Architecture BIM was chosen using the API (application programming interface) in C#. In this paper, we analyze the experience gained and the results achieved. The objective is to create a calculation and graphing module thermal transmission and condensation.

summary Design computation based on data flow graph diagramming is a well-established technique. The intention of DesignScript is to recognise this type of data flow modeling as a form of ‘associative’ programming and to combine this with the more conventional ‘imperative’ form of programming into a single unified computational design application. The use of this application is intended to range from very simple graph based exploratory ‘proto-programming’ as used by novice end-user programmers to multi-disciplinary design optimisation as used by more experienced computational designers.

summary Automation is transforming a significant number of industries today. This paper discusses how the Design and Construction industry is also entering into a new era of automation. In the paper I observe that designers are automating by using parametric tools (BIM, scripting, etc.) while contractors are moving into pre-fabrication and modularization. Both conceptualizations are incomplete. The paper presents how we are in the first steps of creating learning algorithms that develop specific intelligence in design synthesis and how the design field will became even more sophisticated as a second generation of multi-material 3D printing techniques produce new materials.

summary This ongoing investigation aims to learn from nature novel material organizations and structural systems in order to develop innovative architectural system. We developed a multidisciplinary approach, using scientific analysis and design research and prototyping. We focus on the study of a “living fossil” fish, whose armor system is so efficient it has remained almost unchanged for millions of years. We investigate its morphological characteristics, its structural properties, the assembly mechanisms and the underlying material properties in order to derive new principles to design new enhanced structural systems. We use micro computerized tomography and scanning electron microscopy to observe microstructures, parametric design to reconstruct the data into digital models and then several 3D printing technologies to prototype systems with high flexibility and adaptive capabilities, proposing new gradual material interfaces and transitions to embed performative capabilities and multifunctional potentials.

summary Architecture and Technology’s relationship nowadays has arrived to multi-disciplinary practices; they are growing exponentially while keeping away from to architectural discourse, are remarkable for its expressive power and the ability to solve complex problems. This opens the possibility for the generation of the organic, a path discarded by the Modern Movement in the past.Our approach explores three active premises called Morphogenetic Meta-Patterns: discrete processes (systemic guidelines) for the development of performance-based generative systems. These processes arise from Generative Design and their associated paradigms in the creation of a Framework between architecture and related disciplines.

summary The goal of this article is to conceptualize and structure a theoretical proposed framed of ethics in digital technology in architectural design. The methodological vision of this proposal is one of complex epistemology, which seeks to understand applied ethics in a multicultural reality and the digital processes that reformulate contemporary architectural vision. The proposed “Method 7.1: Re-action in Multi-re-form” is based on Edgar Morin’s “Method 6, Ethics”, and Victor Martin’s “Applied Ethics.” The Method 7.1 is formed by seven ethical dimensions that constitute a pattern of complex thought that systematizes the values for the production of techno-architecture.

summary The paper presents a model-based methodology to support multidisciplinary collaboration for the application of photovoltaic systems to buildings. It focuses on the representation of domain specific knowledge necessary for the design of novel PV racking and mounting structures, based on principles of multi-functionality and functional integration. The proposed representation is based on a language for modeling functional requirements in terms of causal behaviors. These behavioral models provide common ground not only for multidisciplinary design, but also for the elaboration of performance metrics and verification procedures for evaluation of design alternatives. The paper concludes with a discussion on the potential of Model-based approach to support innovation in Design.

summary I have conducted a study to explore aerodynamic performance as a driver for skyscraper design, utilizing up-to-date parametric design and computational fluid dynamics (CFD) technologies readily available to architects. Previous scientific research has suggested strategies in modifying the form of skyscrapers for the purpose of improving their aerodynamic performance. I have incorporated six of such strategies into parametric design tool to produce a matrix of 60 prototypes. These prototypes are subjected to qualitative and quantitatively evaluation iterations to yield the most optimized design, with considerations given primarily to aerodynamic performance, and secondarily to structural robustness, program potential, and image attractiveness. The selected design option is further developed into a skyscraper concept. A multi-staged aerodynamic performance-driven design process is the most important result of the study. In addition, two valuable insights have been obtained: first, to inject a new inspiration into the design of skyscrapers, I have implemented the MultiDisciplinary Optimization (MDO) methodology from the aerospace industry. Second, I am able to support form-generation parametric design by quantitative evaluation process.

summary In urban design, researchers have developed techniques to automate both the generation and evaluation of urban street patterns. In most cases, these approaches are investigated in isolation from one another. Recently, a number of researchers have attempted to couple these approaches, in order to enable larger numbers of street patterns to be generated and evaluated in an iterative loop. However, to date, the possibility of fully automating the generative-evaluative loop using optimisation algorithms has not been explored. This research proposes an explorative design method in which urban street patterns can be optimised for multiple conflicting performance criteria. The optimisation process uses evolutionary algorithms to evolve populations of design variants by iteratively applying three key procedures: development, evaluation, and feedback. For development, a generative technique is proposed for constructing street patterns. For evaluation, various performance measures are used, including in particular Space Syntax based Axial Line analysis. For feedback, a Pareto-ranking algorithm is used that ranks street patterns according to multiple criteria. The proposed method is demonstrated using an abstract scenario in which orthogonal street patterns are evolved for a small urban area.

The paper signifies the halfway point in a project initiated at the Azrieli School of Architecture and Urbanism at Carleton University starting in 2013. The printer, entitled 3DB, intends to print concrete elements for the Architecture, Engineering and Construction industry. The printer frame was designed to fit within the bed of a typical half-ton pick up truck or contract trailer. The paper describes the design, simulation and construction of the steel frame, gantry and extruder and makes speculation on future research including improved design of the extruder and nozzle mechanism.
