title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	Hybrid[s] : new pedagogical applications for designing our evolving spatial environment
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 131-136
summary	The continual emergence of new informational and technological systems has impacted our cultural landscape. As society continues to evolve, we are becoming more connected to virtual systems that impact our spatial environment. The awareness and understanding of these invisible forces requires new curricular pedagogies in architectural education. This paper will document an ongoing course that was developed to research new methodologies for working with haptic environments and informational systems. Utilizing a high performance-computing center, students in the class are developing new adaptive intelligent spatial systems that engage a multiplicity of scales. They researched environments for PDA’s (Personal Data Assistance), I-Pods, cellular phones, GPS (Guidance Positioning Systems) and a new immersive virtual dome environment. The goal of the class was to reevaluate how architectural practice in the future will encompass a more holistic approach to both physical and virtual spatial development.

title	Aesthetic Interaction A Model for Re-thinking the Design of Place
doi	https://doi.org/10.52842/conf.acadia.2006.278

summary	We live in a landscape of digital information and communication. Digital technology finds pervasive application in many aspects of modern habitable spaces— environmental control systems, internet based systems for information exchange, cellular systems for instant communication, and the list goes on. In fact, recent Intel studies show that every day we encounter at least 150 different computing devices in our living environments. As computing initiatives evolve intelligent devices that work in the background of our day to day living, several questions arise about how we interact with these devices. The design of “smart” places will eventually involve the seamless integration of both the physical and virtual. Such interventions will lead to a transformation in the way we design. Architects will increasingly find themselves using the computer in design as opposed to design. Over the last few years our lab has been working on several projects, from the level of a room to the level of urban design, that use embedded interactivity and computing as part of the design. This paper describes three such projects, completed at different times, which deal with different problems and the overall impact of computing on the way the designs were developed. The description and evaluation of these projects will be used to develop a theory for the use of pragmatist aesthetics for “information interchange” within architectural design. In short, the paper will explore the evolution of Computer “Aided” Design from a model for designing architecture to a model for designing computing within architecture through aesthetic interaction.

summary	The notions of collaborative exchanges, leadership, and entrepreneurialism that cross disciplinary boundaries were promoted in a digital design-build studio taught in spring 2005. With the starting funds of one dollar, the studio took up the challenge of building two full-scale tensile fabric structures that mark the entrances to a downtown San Antonio building. Structures of 1200 square feet total surface area were successfully designed, engineered, and executed within a semester framework at a final cost of $102,490. Collaborations were fostered with 24 industry partners from Asia, Europe, Australia, and USA, including four structural engineers. Innovative pedagogical, collaborative and project management methods were employed. The studio was structured as a self-organized design “firm.” Positions were created and students were “hired” into the firm to play different roles. The studio utilized web-based communication and project management tools. After a four-week warm-up project that established an innovative studio culture, professional schedules were prepared and the engineers were engaged in the collaborative process of designing the anchors, cables, connections and PTFE/PVC membranes. The peculiarities of digitally designing, fabricating and erecting tensile fabric structures were comprehensively explored. The studio completed all the CNC fabrication, concrete footings and membrane fabrication at local workshops through special partnerships.

summary	Lack of affordable housing is a worldwide problem. Rapid urbanization, rural exodus, and poor governance policies have contributed to the problem and, in response, low-income populations resort to self-construction. The result are informal settlements located predominantly in marginalized urban areas (United Nations, 2015) that develop with neither urban infrastructure nor compliance with building and planning codes (Lall et al., 2006; Patel et al., 2018; United Nations Human Settlements Programme, 2012) and, consequently, offer a poor-quality built environment. The goal of this paper is to methodologically identify physical aspects of such built environments that could be improved. We evaluate a case study, the Santa Marta favela in Brazil, using a holistic housing-quality assessment tool and local building and planning codes as reference. Our results identify the physical characteristics with lower quality standards in the case study and demonstrate the efficacy of the methodology introduced for this purpose.

summary	For a contribution to problem solving processes at different areas, this paper presents the use of Digital Graphics as a knowledge object for a distance teaching/learning workshop. At the Learning Management System, different theoretical subjects with supporting tools were proposed, and exercises requiring collaborative work. An specific didactic situation using available technologies at Internet for 3D modelling, combined with satellite images and geographic information program was proposed. The final works were then shared by a 3D models repository. As a complement of this experience and in relation with their professional work, every student proposed a new didactic situation including Learning Objects, sharing them with the others members of the group, through conceptual maps built up in a co-operative way.

summary	Building with biology will be the most important platform to transform our planet in the next decades. Since 2006, Synthetic Biology (SynBio) has surfaced as the fastest-growing technology in human history. This field is allowing us to manipulate the genetic code, biology, food, and vaccines and ultimately aiming to reshape the very essence of existence. In this paper, we assess the development of SynBio and its impacts on architectural thinking, materials, and particularly in Architectural fiction. In this paper, we argue that there are at least three waves of impacts of SynBio technology in construction: Biomaterials, Engineered Living Materials (ELM), and Bio-Matter or biobots. We explore architectural thinking's domain, involving architects and engineers in research and startups. We embrace the architectural envisioning role and present our design work utilizing observed biological growth algorithms. Synthetic Biology urges questioning not only biomaterials but also the field's overarching vision.

title	Light and Form in Design – A Computational Approach
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 254-257
summary	Shape perception is strongly influenced by the reciprocal relation between light and form. Computational applications can increase the number of design alternatives taking into account possible variations in the relation between light and form. The aim of this study is to discuss a pedagogical experience carried out with 5th semester architectural students, based on a series of exercises prior to the term project. The exercises were concerned with the relation between light and form from an aesthetical point of view and should be understood as examples for the use of computers as tools to creatively accelerate the process of design and learning. The paper is divided in five parts. The first one describes the conceptual background for the exercises, a descriptive method for the identification of light effects in architectural objects based on ideas of shape emergence. The exercises’ methodology is explained in the second part, referring to the use of computational applications in 3-dimensional modeling, material and light simulation. The methodology includes different phases: –creation of bi-dimensional compositions according to symmetry operations; –creation of a minimal living space assigning functions to spaces originated from the former composition; –analysis of the impact of light on the form and spaces created; –alteration of form and materials creating new light effects considering the functions related to the spaces. The exercises alternate work in computational environment in two and three dimensions with the use of mockups, lamps and photography. In the third part the results –student’s design steps– are described. In the fourth part the results are analyzed and some conclusions are outlined in the fifth and last part. The use of emergent forms combined with computational tools has proved to be an effective way to achieve an accelerated understanding of the impact of light on forms as demonstrated by the evolution of the students work during the term and by their final results concerning the term project.

summary	As tools, techniques, and technologies expand design practice, there is likewise an innovation in design teaching shifting technology from a means of production and representation to a means of discovery and development. This has implications on studio culture and design pedagogy. Expanding the skills based notion of digital design from know-how, or know-how-to-do, toward know-for, or knowledge-for-action, forms a synthetic relationship between the skills necessary for action and the developing motivations of a young designer. This shifts digital design pedagogy to a medium of active inquiry through play and precision. As digital tools and infrastructure are now ubiquitous in most schools, including the increasing digital material exchange enabled through laser cutters, CNC routers, and rapid prototyping, this topic node presents research papers that engage technology not simply as tools to be taught, but as cognitive technologies which motivate and structure a design students knowledge, both tacit and explicit, in developing a digital and material, ecological and social synthetic environment. Digital fabrication, the Building Information Model, and parametric modeling have currency in architectural education today yet, beyond the instrumentality of teaching the tool, seldom is it questioned what the deeper motivations these technologies suggest. Each of these tools in their own way form a synthesis between representational artifacts and the technological impact on process weaving a wider web of materials, collaboration among peers and consultants, and engagement of the environment that the products of design are situated in.If it is true that this synthetic environment enabled by tools, techniques, and technologies moves from a representational model to a process model of design, the engagement of these tools in the design process is of critical importance in design education. What is the relationship between representation, simulation, and physical material in a digitally mediated design education? At the core of synthetic pedagogies is an underlying principle to form relationships of teaching architecture through digital tools, rather than simply teaching the tools themselves. What principles are taught through teaching with these tools, and furthermore, what new principles might these tools develop?

summary	Gaming software has a history of fostering development of economical and creative methods to deal with hardware limitations. Traditionally the visual representation of gaming software has been a poor offspring of high-end visualization. In a twist of irony, this paper proposes that game production software leads the way into a new era of physical digital ornament. The toolbox of the rendering engine evolved rapidly between 1974-1985 and it is still today, 20 years later the main component of all visualization programs. The development of the bump map is of particular interest; its evolution into a physical displacement map provides untold opportunities of the appropriation of the 2D image to a physical 3D object.To expose the creative potential of the displacement map, a wide scope of existing displacement usage has been identified: Top2maya is a scientific appropriation, Caruso St John Architects an architectural precedent and Tord Boonje’s use of 2D digital pattern provides us with an artistic production precedent. Current gaming technologies give us an indication of how the resolution of displacement is set to enter an unprecedented level of geometric detail. As modernity was inspired by the machine age, we should be led by current technological advancement and appropriate its usage. It is about a move away from the simplification of structure and form to one that deals with the real possibilities of expanding the dialogue of surface topology. Digital Ornament is a kinetic process rather than static, its intentions lie in returning the choice of bespoke materials back to the Architect, Designer and Artist.

title	The Holy Darkness: A Study of Light in Brihadeshvara Hindu Temple, in Tanjore, Tamilnadu, India (1010 AD)
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 425-428
summary	The study investigates how religious principles govern the treatment of light/darkness in sacred monument. Specifically, a digitized daylight simulation is used in the analysis of Brihadeshvara Hindu Temple, built in 1010 AD in Tanjore, Tamilnadu, India. This sacred monument, listed as one of UNESCO's World Heritage Sites, is an intriguing case study since the treatment of the 'holy light' in the temple is the treatment of the 'holy darkness'.In spite of the importance given to sun in ancient Hindu scriptures, natural light was used very sparsely in Hindu temples. According to Hindu religious belief, when a worshipper is in the presence of the divine, there should be nothing to distract his/her senses (including vision). Therefore, the innermost sanctum is shrouded in total darkness and the progression into the temple is a ritual movement where the devotee goes through the dynamic experience of the darkening spaces of the temple before reaching the dark sacred chamber (see Fig.1). The dictation of the Hindu faith to create this spiritual procession toward the 'holy darkness' is examined in the historic Brihadeshvara Temple by using Lightscape -- computerized lighting simulation software. To run the program, a 3-D CAD surface model of the temple was created and imported into Lightscape. Then the model was assigned materials and its openings and lighting systems were defined. The simulations were run on four interior horizontal (floor) and vertical (walls) surfaces, along four spaces of the procession in the temple. The simulation targeted three time frames: sunrise, sunset and at high noon on March 21st (the equinox). The location of Tanjore, India was used for light conditions. The Lightscape simulations used the process of radiosity to generate single frame daylight renderings along with light analysis of each surface. A lighting animation was then produced in Quick Time.The results of this analysis demonstrate that the average illumination values for specific surfaces of the temple along the procession sequence correspond to the schematic expectation depicted in Figure 1, i.e., a progressively decreased luminance towards the dark innermost chamber. Furthermore, the simulated values were compared to the Illuminating Engineering Society (IES) standards, which recommend ranges of luminance for specific visual tasks and areas. The comparisons showed that the average luminance in the temple, from the illuminated entrance in the east to the darker chamber in the west, is lower than the IES standards for 'public places with dark surroundings' for 'short temporary visits'. Finally, a morphological analysis of the temple along accepted daylight design guidelines corroborated the previous findings. The multi-method investigation of the relationship of light and darkness, light and objects, and the designated light quality in the Brihadeshvara Temple demonstrates the strong influence of the specific dictum of Hinduism on the light/darkness treatment in the temple. The paper concludes that digitized media such as computerized daylight simulations can examine the significance of light/darkness in sacred monuments as a spiritual experience. This quantitative investigation can augment the qualitative studies in the field of historic sacred architecture.

title	Experimenting with 3D Digitization of Architectural Physical Models using Laser Scanning Technology
source	International Journal of Architectural Computing vol. 4 - no. 2, 67-80
summary	This paper assesses the use of 3D Digitization techniques by carrying out laser scanning of typical physical models produced by architecture students. The aim was to examine the product of laser scanning with respect to scanning and 3D modeling processes, and the effects of variables such as characteristics of the models, materials used, and design complexity. In order to assess the similarities and accuracies achieved by the scanning and 3D modeling processes, the research investigated human perception of differences between analogue and digital models. This enabled an assessment of the degree to which digital models were accurate representations of the real ones, and whether laser scanning can successfully be used as a medium to recreate and represent complex architectural physical models. The study presents a potential direction for digital translation in architectural education.

title	Teaching parametric design in code and construction
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 158-161
summary	Automated manufacturing processes with the ability to translate digital models into physical form promise both an increase in the complexity of what can be built, and through rapid prototyping, a possibility to experiment easily with tangible examples of the evolving design. The increasing literacy of designers in computer languages, on the other hand, offers a new range of techniques through which the models themselves might be generated. This paper reviews the results of an integrated parametric modelling and digital manufacturing workshop combining participants with a background in computer programming with those with a background in fabrication. Its aim was both to encourage collaboration in a domain that overlaps both backgrounds, as well as to explore the ways in which the two working methods naturally extend the boundaries of traditional parametric design. The types of projects chosen by the students, the working methods adopted and progress made will be discussed in light of future educational possibilities, and of the future direction of parametric tools themselves. Where standard CAD constructs isolated geometric primitives, parametric models allow the user to set up a hierarchy of relationships, deferring such details as specific dimension and sometimes quantity to a later point. Usually these are captured by a geometric schema. Many such relationships in real design however, can not be defined in terms of geometry alone. Logical operations, environmental effects such as lighting and air flow, the behaviour of people and the dynamic behaviour of materials are all essential design parameters that require other methods of definition, including the algorithm. It has been our position that the skills of the programmer are necessary in the future of design. Bentley’s Generative Components software was used as the primary vehicle for the workshop design projects. Built within the familiar Microstation framework, it enables the construction of a parametric model at a range of different interfaces, from purely graphic through to entirely code based, thus allowing the manipulation of such non-geometric, algorithmic relationships as described above. Two-dimensional laser cutting was the primary fabrication method, allowing for rapid manufacturing, and in some cases iterative physical testing. The two technologies have led in the workshop to working methods that extend the geometric schema: the first, by forcing an explicit understanding of design as procedural, and the second by encouraging physical experimentation and optimisation. The resulting projects have tended to focus on responsiveness to conditions either coded or incorporated into experimental loop. Examples will be discussed. While programming languages and geometry are universal in intent, their constraints on the design process were still notable. The default data structures of computer languages (in particular the rectangular array) replace one schema limitation with another. The indexing of data in this way is conceptually hard-wired into much of our thinking both in CAD and in code. Thankfully this can be overcome with a bit of programming, but the number of projects which have required this suggests that more intuitive, or spatial methods of data access might be developed in the future.

summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

title	Visualizing the Operative and Analytic: Representing the Digital Fabrication Feedback Loop and Managing the Digital Exchange
source	International Journal of Architectural Computing vol. 4 - no. 3, 79-97
summary	Digital architecture is process-based and reliant upon a conversation between digital visualization, analysis, and production. With the complexity of information generated in process-based digital practices, we need to effectively manage and exchange the information. Feedback loops are integral to this process/product, and thus require extensive management of complex versions of visual and data related information. Quite a lot of scholarly attention has been focused upon highlighting innovative projects using digital fabrication and serial customization. However, there is a scarcity of scholarly work about innovations in visualizing and representing the design data integral in this feedback loop. This paper will examine innovative representational devices such as the matrix, sectioning, layering, bracketing, nesting, and other new forms of organizing, visualizing, analyzing, and simulating complex data, intent upon communicating multiple levels of operations during the design and fabrication process. With a rigorous taxonomy of operative and analytic devices for process-based digital design development, we can begin to outline a trajectory for future evolutions in practice. This writing is an attempt to make a few steps in this direction, and demonstrate some of these new representational ideas in practice.

summary	FFR investigates the self-organization of plaster and elastic fabric to produce evocative visual and acoustic effects. Inspired by the work of the Spanish architect Miguel Fisac and his experiments with flexible concrete formwork in the 1960-70s, FFR continues this line of research by exploring aspects of pattern generation and recognition in relation to self-organized form. In line with the theme of the current exhibition, Digital Exchange, the work can be understood as a dialog between physical and digital computation. The form is a result of a negotiation between the digital manipulation of images and the physical deformations of materials under stress. Both digital and physical processes play an equal role in the final form of the plaster tiles.Reflecting on Miguel Fisac’s flexible concrete formwork, there was a desire to investigate the potential for more differentiated patterns while still using the same basic fabrication technique. This was accomplished through the use of a custom-designed script in Rhino that analyzes a given image and translates it into a field of points. These points establish areas of constraint in the elastic membrane of the mould. Through numerous physical tests, the minimum and maximum distances between constraint points was determined and these were entered into the script as limits for the point creation. If the points are too close, large wholes with very thin and weak plaster form whereas if the points are too far apart the amount of elastic deformation is so great that the weight of the plaster can cause failures to occur in the fabric mould. One of the most important aspects of the project is its resonance with the body and our natural attraction and repulsion for certain forms. Through exploring the natural self-organization of material under stress, FFR unintentionally reminds us of our own flesh. The plaster tiles resonate with our own body’s material as it sags, expands, and wrinkles in relationship with gravity, structure, and time.

title	CNC Timber Framing – Innovative Applications of Digital Wood Fabrication Technology

summary	The discourse on depleting natural resources and compromised environments have led to extended research on sustainable designs methods, building practices and materials. Beyond the actual performance of building products and components, research on sustainable building increasingly focuses on the long-term effects of the production, application and life cycle of building materials on the natural environment, human inhabitation and quality of life. Computer aided manufacturing technologies play a significant role not only in the transformation of design and building methods, but also in an extended discourse on cultural development. Globally available technologies connect the design and building process to a broad range of long-term ecological factors by creating a correlation between "the emergent political, economical and social processes and … architectural techniques, geometries and organization." Through this interrelationship to economy and culture, technology and its applications are also directly related to notions of place and territory as well as to fundamental ideas of ecology. The collaborative research and design study for an outdoor theater roof structure at the University of British Columbia Malcolm Knapp Research Forest at Maple Ridge, B.C., Canada, focuses on the use of digital media in prefabrication and material optimization. By utilizing small square section timber and minimizing the use of alienating connectors the research on the wood roof structure illustrates the potential of a design culture that seeks innovation in a broader understanding of ecology routed in regional culture, environmental conditions, economy and tradition. Labor intensive manufacturing techniques are redefined aided by computer controlled machines and virtual modeling of complex geometries is translated into simple operations. The result is a more sensible and accurate response to the place’s demands. In order to generate innovative design interventions that make a constructive long-term contribution to the preservation, maintenance and evolution of the environment, design needs to be based on a comprehensive understanding of its context and the distinctive qualities of the materials used. Following the example of the outdoor roof structure, this paper aims to define innovative design as work that resonates at the intersection of the fields of technology, material science, manufacturing processes, techniques of assembly and context that constitute the expanded context or complex ecology that projects need to engage. It is in design research studies like for the outdoor theater roof structure with focus on CNC wood fabrication technologies that the common design and building discourse is put to question, boundaries are explored and expanded and the collective understanding is improved towards ecological design.
