title	Structural Evolution: A Genetic Algorithm Method to Generate Structurally Optimal Delaunay Triangulated Space Frames for Dynamic Loads
doi	https://doi.org/10.52842/conf.ecaade.2009.173
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 173-180
summary	This paper presents an evolutionary algorithm that draws its power from the literal interpretation of the natural system’s reproductive process at a microscopic scale with the scope of generating optimal Delaunay triangulated space frames for dynamic loads. The algorithm repositions a firm number of nodes within a space envelope, by establishing Delaunay tetrahedra and, consequently, creating adaptable optimised space frame topologies. The arbitrarily generated tetrahedralised structure is compared against a canonical designed one and the results of this comparison indicate that the method proposed has advantageous properties and is capable of generating an optimum structure that exceeds statically the performance of an engineered tetrahedralised space frame.

title	A Form-making Algorithm. Shape Grammar Reversed
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 453-466
summary	Under the assumption that design is a hypothetical test of building, this paper introduces a method of employing architectural knowledge through direct manipulation of geometric objects. Proposing a framework for retrieving and analysing not only what is modelled but also how it is designed, this paper demonstrates that designing can be viewed as an object of research. The paper also discusses the issues pertaining to the implementation of the aforementioned framework.

title	Analog vs. Digital: why bother?
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 117-128
summary	Architects take advantage of a broad palette of tools and media for design, analog and digital, because each tool has its own strengths and weaknesses and provides an additional value—an added level of vision—to the architect. This closely relates to the notion of Critical Points for Change (CPC) a contribution this study makes towards a better understanding of the uniqueness of the conceptual design process. CPC are crucial moments when the architect suddenly becomes able to “see” something which drives him to go back and either alter his idea and refine it or reject it and pursue a new one. They are crucial parts of the design process because they are a vital mechanism for enhancing design. The right choice and smooth combination of design tools, analog and digital, is critical for the design outcome. Using multiple tools allows the designer to overcome the possible influences and limitations imposed by a single tool. The current and evolving landscape is illustrated by coexistence, complementing and evolution of tools. The answer to the pseudo-dilemma of analog or digital is both.

title	Parametrizing Indian Karnata-Dravida Temple Using Geometry
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 409-420
summary	The Karnata-Dravida temple tradition flourished and evolved for 700 years. The evolution of the typology was demonstrated through the structure. However, as the Shastras or ancient texts proclaim, the underlying principles of geometry remain unchanged. Geometry and the unchanging principles of construction made the architects experiment with form, material and ornamentation. Geometry does not only mean shapes or two dimensional diagrams but it is a rule to amalgamate all the elements to form a dynamic form of a temple. The paper validates the use of geometry through an evolving sequence of Karnata-Dravida temples with the help of an analytical model created using the grasshopper software. The components of the model are based on the geometric rule (the basis for parametrizing) and parameters of the algorithm – plan forms, organizational compositions, vimana or superstructure composition – which result in a geometry. Even though building science is an old tradition, the use of computational procedures reveals the predictable nature of temples in the Dravidian clan and enables the analysis of existing temples, development of new possibilities or evolution of interpreted forms. Hence, enriching the existing understandings of previous scholarships in the field of temple architecture with an entirely new system of interpretation. In the age of technology where analytics plays a crucial role in almost all sectors, ancient temple architecture in India unfortunately falls behind when it comes to computational methods of restoration or reconstruction. This research questions the applicability of computational technology as a facilitator in preserving or reconstructing existing temples while maintaining its creative liberty.

summary	The following text reports a workshop activity performed at LAMO3d - Laboratório de Modelos 3d e Fabricaç?o Digital, PROURB FAU UFRJ that addresses the instrumental domain within the new digital manufacturing capabilities such as 3D printing, laser cutting and parametric design, and on the other tries to overcome the activity as a mere technical training. This concern implies a larger effort that goes towards the incorporation of a coherent discourse and has the ability to validate within the contemporary setting these new operative actions.

title	Virtual Reality: Computers Mimic the Physical World
source	New York: Facts on File
summary	In the Science Sourcebook series, a clear and sensible approach to the wonders and mysteries of virtual reality, including its history and some possible scenarios for the future. Grady compares the state of virtual reality to the situation of television in its earliest years: Everyone thought it was great, but it was wildly expensive, and the technology had not yet caught up to the possibilities. He takes a tour through virtual reality's history, and describes its current uses, still in their infancy, in medicine, architecture, business, science, and, of course, fun and games. He writes quite accurately about the function of virtual realityessentially to fool the mind and body into creating a multidimensional experience from computers, software, and devices.

title	A creative form-finding tool: Deformation of plastic sheets due to the influence of temperature and gravity
source	International Journal of Architectural Computing 2024, Vol. 22 - no. 1, 1-27
summary	A form-finding technique based on the deformation of plastic sheets by the action of gravity and temperature increase is proposed, allowing the exploration of complex geometries to support form-giving processes within architecture projects, both by students and practitioners. Using an analog and computational approach, the ideal material for the technique was selected from a multifactorial experiment. Semi-structured analog experimentation was carried out based on inputs, rules, and outputs previously identified, and the resulting models were morphologically analyzed, to later translate the components of the analog experimentation into a computational algorithm to carry out computational experimentation. The technique can be used as a generator of novel forms possessing adequate transformational qualities. Finally, potential applications of the technique and avenues for future research are presented

title	Beauty - the indispensable category explained, justified and critically employed
doi	https://doi.org/https://doi.org/10.1007/s44223-024-00078-9
source	Architectural Intelligence Journal
summary	Beauty as the manifestation of aesthetic responses and valuations is a human universal. All societies operate with (a version of) the category of beauty. We all navigate the world aesthetically. Architecture and the design disciplines together shape the outward appearance of the social world. Therefore, beauty as the engaged response to appearances should be an indispensable category of all design discourses, including architectural discourse. However, beauty is an increasingly embattled and by now nearly extinct category within a conscientious architectural discourse that is rightly aspiring to rational accountability and evidence-based propositions. Beauty has been eliminated from the discipline’s discourse because it is seen as subjective and irrational, as an irresponsible diversion or distraction from architecture’s societal tasks. However, beauty is clearly not being abandoned by the end-users of design. Nor are aesthetic choices absent from actual contemporary design practice. Beauty is just no longer being explicitly referred to.

title	Designing Out Urban Heat Islands - Optimisation of footpath materials with different albedo value through evolutionary algorithms to address urban heat island effect
doi	https://doi.org/10.52842/conf.caadria.2019.2.603
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 603-612
summary	The Urban Heat Island (UHI) effect is pronounced in dense urban developments, and particular an issue in the case study city of Parramatta, where temperature increases are impacting use of public space, health, and economic productivity. To mitigate against elevated temperatures in built up areas, this research explores the optimisation of paving material layouts through using an evolutionary algorithm. High albedo (reflective) materials are objectively cooler than low albedo (absorbent) materials yet tend to be more expensive. To reduce the amount of heat absorbent pavement materials whilst keeping in mind material costs, a range of materials of different albedo levels (reflectivity) can be assigned on the same path using an evolutionary algorithm to optimise the coolest materials for the cheapest price. Over the course of this paper, this research aim will be approached using visual scripting software such as Grasshopper to simulate daylight analysis and to generate an optimisation algorithm. Previous research on the topics of UHI have revealed different methods for solving specific problems, all focusing on using software analysis to determine an informed decision on construction. The paper contributes via a computational approach of material selection to battle urban heat island effects.

summary	The SHADOWPACK package of computer programs has been developed to facilitate shading evaluations, for the direct component of solar radiation, with general 3D models. An interactive solid modelling program allows the user to construct and view the 3D model before saving it for further analysis and display. Other programs permit the graphical display of the shading situation throughout the year, the quantitative assessment of energy received on different faces of the model, and the display of the distribution of energy received on particular faces by means of contour plots. The use of the computer graphics approach has proved particularly convenient because of the similarity between the techniques used for graphical and numerical algorithms

title	A Knowledge Based Computer- Aided Solar Design System
source	ASHRAE Transactions (American Society of Heating, Refrigerating and Air-Conditioning Engineers). Atlanta, GA: 1990. v.st.-96-2: [5] p. : ill. includes bibliography
summary	A knowledge based computer-aided architectural design system (KB-CAAD) for the schematic design and evaluation of passive solar buildings is presented. The presented tool is based on the integration of knowledge based and procedural simulation methods with any available CAAD system for building representation. The knowledge base contains the heuristic rules for the design of passive solar buildings. Whenever possible, the knowledge base guides the designer through the decision making process. However, if 'rules of thumb' are not acceptable for the particular design problem, the KB-CAAD tool guides the architect towards the optimal solution, by using a procedural simulation model. It is demonstrated, through a case study, that the proposed knowledge based design system not only leads to the design of better solar buildings, but that it takes less time and man-power to introduce the geometrical data that would be needed for a regular non-solar building representation

summary	This work discusses how locative media and the democratization of geoprocessing technologies have reconfigured our experience with the urban space, opening up new territories for the construction of the public. It also discusses perspectives and challenges that speculative practices with locative media bring to disciplines such as design, architecture and engineering, and to the production of more sustainable ways of life. For that matter, this work presents some experiments with locative media and digital cartographies that aim to give visibility to our social relation with the urban space and to support processes of sense-making about issues of public interest.

title	The Fear Of The Digital: From The Elusion Of Typology To Typologics
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 255-266
summary	It might seem that architecture has been forced to choose, once again, between two worlds of existence. One of them might be the construction of the tangible, the other, a “formal fantasy” that will never reach a legitimate status among the “tectonic” or the “structural”. This vague spectrum has confirmed the fear of loosing typology as a proof, of loosing a foremost validation for architecture. But one could see the virtual as a possibility to generate a structure of discourses and interactive tactics to reformulate the typological. This meaning that the virtual could transcend the so called “graphic” stigma and actually produce the discourses and spatial strategies to radicalize typology and move towards a radicalization of content.
