title Information Controlled Erosion
source ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 145-150
summary This paper documents research of a design process that interrelates a single information model to 5-axis, waterjet cutting technology. With the intention of creating an optimized design, data is streamed through a building information model that controls geometry parametrically by a component/system relationship. At the scale of a 4’x8’ panel, material properties and pattern variability act as underlying initiators of design rather than post-rational information. In a manner uncommon to the discipline, the information model is being used as a generative tool, rather than as one for mere documentation. The research assigns a limestone wall type to the panel—a material predominantly used in areas where it is indigenous and typically desirable for its texture, color, and thermal properties. The intention is to develop potentialities through material specificity in the information model’s conceptualization. The water-jet process is then used to erode the limestone to achieve varying fields of scalar voids. In addition, the thickness of wall cladding attenuates for figuration and interest. The final stone panels transition from a rain screen system to a solar screen that modulates light, thereby linking environmental intentions to current technological capabilities. The information model is exported for analysis of daylight and structural dynamic qualities and quantities as part of the workflow. Parameters within the information model database facilitate a dimensionally controlled iterative process. Moreover, fabricating with building materials via the information model expedites a design and makes possible for materiality to move beyond merely conceptual representation.

summary Intelligent Virtual Environments integrate AI techniques with 3D real-time environments. As such, they can support interactive problem solving, provided the underlying AI techniques can produce solutions within a time frame matching that of user interaction. In this paper, we describe an intelligent virtual environment based on Constraint Logic Programming (CLP), integrated in a real-time 3D graphic environment. We have developed an event-based ap-proach through which user interaction can be converted in real-time into appro-priate solver queries which are then translated back into automatic reconfigura-tions of the Virtual Environment (VE). Additionally, this framework supports the interactive exploration of the solution space in which alternative solutions (configurations) can be found. We demonstrate the system behaviour on a con-figuration example. This example illustrates how solutions can be interactively refined by the user through direct manipulation of objects in the VE and how the interactive search of alternative solutions in the VE is supported by these type of systems.

title Modulating Thermal Mass Behavior Through Surface Figuration
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 202-211
summary This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

title Erratic - The Material Simulacra of Pliable Surfaces
source Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 145-152
summary This paper examines how designers can invigorate designs with a sense of liveliness and indeterminacy through manipulation of pliable materials. Two approaches to material manipulation are defined and juxtaposed in the paper: The control associated with Frei Otto's elegantly tensioned membranes and the noise associated with Sigurd Lewerentz's intensely material brick walls. These historical approaches become pertinent in relation to current opportunities offered by material simulation software in architecture. Simulation may be used to increase control over the materialization of design, but is at the same time a way to introduce the noise of real-time, real-world experiments into digital design. The paper presents this discussion in parallel with documentation of the research project 'Erratic', a recent installation carried out by the authors' practice Norell/Rodhe. Constructed from polyurethane cold foam, the project combines analogue experiments with digital simulations to target architectural qualities like mass, figuration and relief.

title Generative Natural Flux
source International Conference on Generative Art
summary I believe to interpret the thought of all the participants to this fourth conference on Generative Art affirming that generative art is a deep creative experience and, somehow, visionary too. This experience, in fact, anticipates the possible evolution of the fields proper of humancreativeness, rediscovering paths and approaches to ideation that have been proper of one of the most fertile moments of the human history and culture as Renaissance. In this paper I would like to deal with some aspects, and also some different approaches of generative creativeness. In particular, the importance to use specific reading keys, bothsubjective and objective, the possibility to reach concrete and feasible design results entering a complex figuration of possible incoming worlds. In other terms, to reach projects directly interfaceable with productive reality. Lastly, I will evaluate if and how it is possible andprofitable to use the random factor in evolutionary processes, investigating on the differences that the use of such factor involves in the creative and design experience and the quality of the obtainable results.But how can we define generative creativeness?

title The digital visualization of the future architecture and the intellectual operations
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 257-263
summary It is sustained here that the designer before carrying out any trace (digital or similar) on the architectural design to solve, the person carries out a series of intellectual operations that allow him/her to carry out this traces with more precision, delimitation, knowing the space that will be realized in future. This work explains how the digital visualization of the architecture will be carried out in a future, based on the construction of the knowledge that Piaget proposes about the cognitive structures and the significant learning, as well as the metacognición that Vygotsky and Ausubel; the topic of the language is also approached, because it is thought that the language is very related with the figuration element that is presented in the document as one of the intellectual operations and the pattern that Wittgenstein exposes in its book “Tractatus, logical-philosophicus”, where he explains how the figuration is given by means of the interrelation among the elements of the figure and how it comes from the linguistic question. This helps to understand the design process in its initial stage (mayeutic) and has a pedagogic application. [Full paper in Spanish]

summary This proposal is a continuation of a body of work we call ‘objects wrapped in objects’, which deals with discrete, chunky objects gathered and squished together in a sack. This strategy creates complex interstitial spaces and layered interiority, making the contemporary museum a space of surprises and discrete experiences rather than an endless continuum of paths. Tristan Garcia, the object-oriented philosopher, talks about the infinite regress of things inside of things inside of things, except the world, which everything is inside of and therefore cannot itself be inside of something else. For him, the concept of a ‘sack’, literally, is a diagram of the conundrum of how things can simultaneously be autonomous from one another but also contain other things. This conundrum is the core of our proposal, in that the building should appear simultaneously as multiple autonomous objects but also as a larger, emergent object with its own properties. The vibration between these two ways of existing creates a visual indeterminacy that is alluring and durable.On the south side facing the Park, the sack is sliced open to reveal an incongruent inner world of stepped and stacked public space. This space is formed by way of an inner liner, which delaminates from the sack surface. Permanent gallery spaces are housed in the space between liner and sack. The building is re-enclosed with a glass membrane which is not coincident with the sack silhouette, creating an open-endedness or deferral of interiority in the project. Black jack-like objects house various other functions such as the temporary galleries, theaters, research area, library, and offices. The interstitial spaces between objects and sack are technically exterior space, but they are enclosed with infill glazing deep inside reveals. These spaces are inhabitable and contain the primary circulation of the building.The sack is articulated with architectural tattoos that subvert subdivision logics in favor of the freeform figuration allowed by composite construction. Tattoos are executed in such a way as to blur the edge between discrete objects and visually re-establish the larger object, as if qualities from the black objects begin to loosen and drift onto the sack. Finally, the building is squished into a ‘ground object’ which is in turn squished into the land. The looseness between building and ground object allows for passage underneath the building. The looseness between ground object and land emphasizes the object-hood of the building complex. This move contrasts with exhausted ideas of buildings becoming landscape or otherwise disappearing into context
