title	Efficiency of Lightweight Structural Forms: The Case of Treelike Structures - A comparative Structural Analysis
source	Vienna University of Technology; Building Science & Technology
summary	This work addresses the structural efficiency of lightweight tree-like structures for three case studies: Stuttgart Airport, Beaverton Library, and Thermal Bad Oeyenhausen. The case studies are simulated using Build simulation software, to determine the stresses induced in each structure. The material efficiency and shapes areexplored in terms of load bearing structures. Hybrids of the above structures are formed to compare the pattern morphology used by various types of tree-like structure and assess the structural behavior. In addition, (steel, wood and concrete) materials are compared to determine which would have better structural performance. In order to show the resemblance between the growing trees and the tree-like structures, an example of both cases is simulated and stresses evaluated. Results show that, in general, the minimum stress and deformations are obtained for steel. Structures made out of this material also exhibit higher load bearing capability, optimum stability factors and the best geometric efficiency, inspite of higher specific weight (10 times wood, and 3 times concrete).

title	Knit Architecture: Exploration of Hybrid Textile Composites Through the Activation of Integrated Material Behavior
doi	https://doi.org/10.52842/conf.acadia.2016.254
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 254-259
summary	The hybrid system in textile composites refers to the structural logic defined by Heino Engel, which describes a system that integrates multiple structural behaviors to achieve an equilibrium state (Engel 2007). This research explores a material system that can demonstrate a hybrid material behavior defined by the differentiated tensile and bending-active forces in a single, seamless knitted composite material. These behaviors were installed during the materialization phase and activated during the composite formation process. Here, the material formation involves two interdependent processes: 1) development of the knitted textile with integrated tensile and reinforced materials and 2) development of the composite by applying pre-stress and vacuuming the localized area with reinforcements in a consistent resin-based matrix. The flat bed industrial weft knitting machine has been utilized to develop the knitted textile component of the system with a controlled knit structure. This enables us to control the material types, densities, and cross sections with integrated multiple layers/ribs and thus, the performance of the textile at the scale of fiber structure. Both of these aspects were researched in parallel, using physical and computational methods informed and shaped by the potentials and constraints of each other. A series of studies has been utilized to develop small-scale prototypes that depict the potential of the hybrid textile composite as the generator of complex form and bending active structures. Ultimately, it indicates the possibilities of hybrid textile composite materials as self-structuring lightweight components that can perform as highly articulated and differentiated seamless architectural elements that are capable of transforming the perception of light, space, and touch.

title	Structural Analysis as Driver in Surface-based Design Approaches
doi	https://doi.org/10.52842/conf.ecaade.2007.109
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 109-115
summary	This ongoing research argues for novel strategies to integrate structural analysis data in an architectural design approach. Instead of a linear procedure of synthesis, analysis and post-rationalisation a synthesis/analysis loop is installed that uses structural analysis data as design driver from early on. The approach is not aiming for a pure force-driven form-finding or optimization process but regards structural performance as one design criteria among others. Equilibrium between multiple parameters is aspired instead of a single-parameter-optimum. The research is conducted by a custom-made digital interface between a 3d modelling software and an application for structural analysis of space frames structures. Surfaces are translated into meshes with supports at user-defined nodes and then exposed to its dead load in the structural analysis software. The resulting nodal deviation is feed into an algorithm that steers the appropriate reaction towards the local stresses and deviations, taking into account the mesh topology, its supports and their position in the mesh. The initial mesh is optimized in shape transformed back into a double-layer surface model in the 3d software which evolves into an interconnected two-layer space frame. An instant feedback from synthesis to analysis and vice versa is installed. Analysing techniques migrate into the realm of synthesis.

title	Development of Design Workflows for Kinetic Structures Using Fuzzy Logic
doi	https://doi.org/10.52842/conf.acadia.2007.250
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 250-261
summary	Kinetic structures offer the means to significantly expand the functional and performance features of traditionally static architectural solutions. However, the added element of motion creates considerable challenges during conceptualization and introduction into existing design workflows. Rigidly foldable shells offer tremendous potential for developing kinetic architectural structures. They require few support points, eliminate sliding overlaps and are relatively easy to mock up as initial concepts. Achieving the desired motion range, however, requires a significant design effort. If performed manually, the motion optimization is tedious and unpredictable. This paper examines possible optimization algorithmic strategies with the use of fuzzy logic. Specifically the paper focuses on the application of fuzzy logic as a tool for effectively negotiating modifications of complex linked geometries while using intuitive, high level statements and directives. Highlighted is the potential of fuzzy logic-based algorithms as tools that can help the transition of existing design workflows into environments that can handle extended challenges involving kinetic geometries.

title	Foam Structures: A Comparative Structural Efficiency Analysis Based on the Building Case "Watercube"
source	Vienna University of Technology; Building Science & Technology
summary	Foam structure in macro-scale has arisen as a new type of large span building structure recently which is a product of cooperation of advanced structural design, radical architectural design approach, and computer and software technology, and efficiency of foam structure became an important question to answer which could help further structural improvements. This study analyses efficiency of large span foam structure relative to conventional large span building structures with a parametric simulation method. Space frames are a special case of conventional large span structures one compared with foam structures, because it satisfies criteria such as being lightweight and three-dimensional as foam structure. Analysis is based on the comparison of base cases of foam model and space frame model, which are developed on light of real projects the Water Cube and the Symbol Zone of Expo’70, based on the parameters structural depth, weight and displacement, and vertical and horizontal load cases. During the analysis structural behavior of base cases were simulated by using a special structural behavior simulation program. It was found that foam model is more efficient than space frame model in terms of structural depth which is an important issue for large span building structures from both architectural and engineering point of view. Capability of spanning large distance with significantly less structural depth makes foam structure a preferable, new generation, steel structure for large spans. Moreover, the development process of base case foam model demonstrated the critical importance of geometrical design concerns of foam structure. Structural behavior simulations were exposed that structural optimization is one of the vitally important process of structural design of the foam structure.

title	Best Practice for Achieving Real-Time Virtual Reality Architectural Visualization
doi	https://doi.org/10.52842/conf.caadria.2007.x.i4m
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Real-time rendering is the most fundamental aspect of the virtual reality technology, which is always, a balance between hardware advancement and efficient software algorithm upgrades on the one hand and the demands of the quality output on the other. As architects who utilize this technology, what we can do as users is to optimize the parameters we can control in the files we input to run the simulation. Thus the identification of the few variables we can control to prevent a lagging performance or ghosting which is no longer realtime. The frame rate above all is the measurement to determine whether a simulation is real-time or not. The research aim is to identify the biggest contributing factors among the few identified. The intention is to save time and effort by optimizing the selected factors in projects so that we do not have to optimize all of them. The workflow will also be a lot faster and projects can be done efficiently. The final part is to run satisfaction tests among users to evaluate those biggest contributing factors and the qualities acceptable by users. This is to eliminate the added processing power needed to run bigger files if they do not contribute much to improved quality.

title	Self-shaping Textiles - A material platform for digitally designed, material-informed surface elements
doi	https://doi.org/10.52842/conf.ecaade.2020.2.021
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 21-30
summary	Despite the cutting edge developments in science and technology, architecture to a large extent still tends to favor form over matter by forcing materials into predefined, often superficial geometries, with functional aspects relegated to materials or energy demanding mechanized systems. Biomaterials research has instead shown a variety of physical architectures in which form and matter are intimately related (Fratzl, Weinkamer, 2007). We take inspiration from the morphogenetic processes taking place in plants' leaves (Sharon et al., 2007), where intricate three-dimensional surfaces originate from in-plane growth distributions, and propose the use of 3D printing on pre-stretched textiles (Tibbits, 2017) as an alternative, material-based, form-finding technique. We 3D print open fiber bundles, analyze the resulting wrinkling phenomenon and use it as a design strategy for creating three-dimensional textile surfaces. As additive manufacturing becomes more and more affordable, materials more intelligent and robust, the proposed form-finding technique has a lot of potential for designing efficient textile structures with optimized structural performance and minimal usage of material.

title	An Integrative Design and Spatial Visualization System for Cable Strut Self-tensioned Structures
doi	https://doi.org/10.52842/conf.ecaade.2007.027
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 27-34
summary	Novel conceptions of structures consisting of spatial formations of struts and cables present a uniquely defined morphology and structural performance, and offer opportunities for innovative applications in building design. A common feature of these structures is that their spatial geometry is not “a priori” given. This paper is focused on a specific type of cable-strut structure that occurs from the assembly of self tensioned cable-strut modules The spatial configuration of these structures is very complex and necessitated the development of elaborate geometric algorithms that permit the generation of their formal geometry in a virtual 3D environment. To facilitate both the design and the construction of such structures, a spatial visualization system, which integrates a) algorithms for initial form generation, b) geometric parameters that simulate construction stiffening processes, and c) appropriate structural analysis methods, has been developed. The structural organization and parts of this system are presented in this paper. The system renders feasible the exploration of alternate geometries with various levels of pre-stress and displays initial and final configuration of the structure. It also allows for structural analysis data visualization. Examples of projects designed with the assistance of this system are included and discussed.

summary	The wood - humidity interaction of solid wood has been tested through generations on Norwegian traditional panelling. This concept has been further explored by Michael Hensel and Steffen Reichert with Achim Menges on plywood and laminates in basic research. Plywood or laminates are better programmable but they are less sustainable due to the use of glue. This research focused on predicting the performance of solid wood in tangential section which is applied to humidity-temperature responsive screen for industrial production. With the method Systems Oriented Design, the research evaluated data from material science, forestry, meteorology, biology, chemistry and the production market. Themethod was introduced by Birger Sevaldson in 2007 with the argument that the changes in our globalized world and the need for sustainability demands an increase of the complexity of the design process. (Sevaldson 2013)Several samples has been tested for its environmental interaction. The data has been integrated in parametric models that tested the overall systems. Based on the simulations, the most suitable concept has been prototyped and measured for its performance. This lead to another sampling of the material whose data are the basis for another prototype. Ray 2 is an environmental responsive screen that is airing the structure in dry weather, while closing up when the humidity level is high, not allowing the moisture inside.

title	Simulating Dynamic Forces in Design with Special Effects Tools
doi	https://doi.org/10.52842/conf.ecaade.2007.219
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 219-226
summary	Special effects technology can facilitate dynamic sketching in the early stage of a design project without needing time-consuming effort. This form of sketching was tested in a design studio taught by the author. The study of dynamic materials and oceanfront site conditions set the stage at the beginning of a design process for a more comprehensive analysis later on. On the one hand, the risk of using special effects tools is that the visual look can seem convincing, but the apparent result is based upon an overly simplified set of assumptions. On the other hand, the use of such technology can be very stimulating to the design imagination without requiring complex analysis that may bog down the free flow of ideas. Once a greater commitment is made to a particular design proposal, more complete physical analysis and modeling can be undertaken to help avoid the risk of false first impressions. In the studio, cloth simulation was used to develop the design of tension membrane structures (tents) that retracted and unfurled in a series of complex movements. Fluid dynamics effects were used in the design and development of related boat dock facilities. A wind-tunnel simulation tool was used to explore the performance of the tension-membrane fabrics under varied wind loads. The visualization techniques were complemented by ¼ to ½ scale assembled components created by rapid prototyping. The use of an actual wind-tunnel further tested the prototypes in some cases. On the whole, quickly implemented special effects were the starting point for reacting to and developing some initial design concepts and served as the basis for more complete physical modeling of prototypes later on. Using animation as a design method is well established in other work (Hirschberg 06). Animation is also a helpful way to work out the step by step assembly of complex architectural form (Mark 95). The special effects tools permit a larger range of initial design alternatives to be initially considered that are subsequently narrowed down by physically based prototypes that are more predictive of real world performance.

source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 21-26
summary	Steel tubes as construction material have an enormous capacity. CNC bending machines have the ability to deform material into all three dimensions in contrast to other popular CNC techniques for architectural design that use subtractive methods like laser-cutting and milling. The research examines the potential of a digital deforming process of CNC-Bending. During three months the authors developed several design concepts, programmed the necessary software for generating the structure and produced three architectural prototypes shown at an exhibition. Altogether they were constructed out of more than 500 pieces of steel tubes and over 5000 bends.

summary	In this paper we track the evolution of computational design from its analog origins to its contemporary digital regime. Our long term goal is to qualify and quantify the implications of digital computation on design thinking and its influence on the architectural practice. Meanwhile, we present the results of our past few years of collaborative research in design and computation that illustrate the nature of the intellectual engagement required for appreciating the potential of digital design thinking and making. In a temporal frame, these results are expressed as a constellation of punctuated innovations emerging sporadically during the painstaking process of tackling architectural problems using digital means. In the long run, they hopefully amount to an approach to fleshing out a paradigm shift from analog to digital and building a knowledge foundation of architectural methods.

summary	In this paper I present and reflect upon a five-year investigation of designing digital tools for designing in the area of architectural space grid structures. I understand design as a novelty and knowledge generating conversational process as described by Pask (see Scott 2001) and Glanville (2000). Furthermore, I regard making design tools as a design task in itself, rendering this paper a reflection on designing for designing. This paper gives a report on observations I made during the toolmaking study, and subsequently contextualizes these observations using second-order cybernetic theory. This reflection focuses on different relationships between observers and systems, on conditions under which observers construct knowledge and on limits of supporting others in this activity.

title	Architectural eLearning: An inquiry into the fuzzy boundaries that separate education and instruction [Architectural eLearning. Una indagación sobre los límites borrosos que separan la educación y la instrucción]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 155-158
summary	This communication is based on the development of a new subject to be imparted in collaboration with three Departments (Visual Communication, Projects and Construction) at the School of Architecture of Barcelona. It is a work that has been financed with a special grant from our university, aimed at the development of new teaching modalities and, in particular, of those that would develop the use of new technologies, collaboration among university departments and eLearning. The aim of the communication is twofold. First, to present some results that we consider valuable in themselves, as much for the techniques as for the methodology that we have used. Second, to propitiate a debate on the new situation that the teaching of architecture is moving to, due to the advance of a series of instruction methods where the methodological organization, the storing of informative material and the preparation of autonomous interactive systems, open more and more effective roads of learning but that, at the same time, point towards a new educational structure that fits badly within the traditional structures in which we have still to work daily. Regarding the first point, the main aspects to highlight are: a) the development of a selflearning system by means of a very complete series of tutorials that allow a gradual acquisition, depending on the necessities or interests of each student, of geometric modeling, parametric design, visual simulation and interactive animation techniques, b) the development of a system of general information supply and on line comments and corrections. Regarding the second point, a provisional theoretical framework has been elaborated based on the consideration of the ubiquitous visual communication media as misleading mediators of a personal relationship. This theoretical frame has been tested by a few experiences carried out with the collaboration of students implied in the project. The general conclusion is that both challenges must be faced at the same time: new educational technologies must be analysed and integrated in our curricula and a new theoretical framework, able to clarify the difference between instruction and education, must be developed in parallel with those technologies.

title	Innovative CNC Timber Framing - Technology and Cultural Expression
source	International Journal of Architectural Computing vol. 5 - no. 3, pp. 469-486
summary	he design-build project for the outdoor theater roof structure at the UBC Malcolm Knapp Research Forest at Maple Ridge, British Columbia, explores technical, spatial, and cultural aspects of CNC wood fabrication. References for the project are technological innovation and formal expression of contemporary wood structures. The roof project illustrates how spatial concepts are informed by the logic of fabrication and methods of assembly. A reciprocal relationship between technology, space, and locale suggests that the introduction of new technology coincides with new spatial concepts. Innovative design in this project is defined as work that resonates at the intersection of the fields of technology, material science, manufacturing processes, and techniques of assembly that constitute the expanded context that projects need to engage. It is through collaborative design research on CNC wood fabrication technologies that common design and building practice is put into question, and boundaries are explored and expanded.

summary	This paper is presentation of resulting physical models that were used to explore the relationship between design modeling in CAD and digital fabrication with plywood sheets. We explored a process in making tabletop models with digital fabrication machines and thin plywood sheets. Each was built from combination of predetermined wood joining techniques and structures. These models are believed work as simulation of full scale constructs that inform CAD modeling. Results illustrate the limited potential of parametric modeling and inform fabrication and assembly of design variations.

title	The Role of GIS in Documenting Bahrain’s Historic Cities
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 517-526
summary	Geographic information systems have long been established as useful tools for urban planning. The aim of this study is to put forward applications of GIS (Geographic Information Systems) to urban conservation in cities with architectural heritage. The study presents a specific database design to be integrated within a GIS, and the methodology of gathering data for such a database. This study concerns Bahrain’s architectural heritage, which includes many significant historic buildings as well as an overall traditional character of Bahrain’s old towns. This heritage is endangered due to extensive new urban development and the general neglect over the past decades. The study also describes an experimental database that is implemented for documenting the urban character of the old towns of Manama and Muharraq. This database was tested during a partial visual survey of Manama. It is hoped that this database will be the nucleus of a long-term process of urban conservation in the Kingdom of Bahrain. The work described here is part of a larger study conducted by the UNDP (United Nations Development Program) and the municipal government in Bahrain. A group of international experts in urban planning, urban design, and historic preservation also presented their own specific recommendations. The author of this paper was responsible for designing the GIS that helps in documenting the historic cities of Bahrain. This report proposes the development of a geographic information system for urban conservation planning. The system supports planning specialists and decision makers in their areas of work, such as the creation of urban conservation zones and redevelopment strategies. The system documents existing structures and their present conditions in order to assist in decisions regarding their preservation, restoration, and possible reuse. Such a system will also help the municipalities in regular heritage management tasks.

title	4D Building Model - A Conceptual System of the Time Dimension in the Building’s Life
source	Vienna University of Technology; Building Science & Technology
summary	The research topic ”4D Building model: a conceptual system of the dimension of time in building’s life” is the concept of a web-based interface of a databank that stores and visualizes information of the building’s life process. It is an organization data model that brings together the serial steps of the lifetime of a building, following the design, construction and its operation time. Observing the aforementioned process as an entity, the model aims at approaching the passage of time during it, depicting the temporal relations between past, present and future steps. Visualized stored information depict the becoming of the building in time. It attempts to approach the idea of 4D architecture and explore how the dimension of time is incorporated into the model. It studies the role of information in architecture and building process observing it changing in time. The aim of this research project is to define the frame of a conceptual information system, that could develop in a plug-in by an existing design software. The model will support the design and building procedure operating as the building memory, and reporting its behaviour during its life time. In its data base, there will be reported the serial and parallel actions during the design and construction phase and additionally the reports of the monitoring evaluating system during its operational time. The final model should provide several possibilities of decision making, regarding the energy consumption, the materials life span, the costs, the participation of different firms and components.

summary	The current trend in architectural design towards architectural computing has been treated both from a philosophical standing point and as an operational systems’ problem, in a quest for explications which could at last break ground for a more broad development and adoption of design tools. As Kostas Terzidis (2007) puts it, the intuitiveness that architects have put on so high a pedestal seems to be the central issue to be dealt with by both views. There seems to be no apparent shortcut toward the reconciliation between traditional practice and new media and most certainly it is not only a problem of interface design, but one of design method clarification and reinterpretation of those methods into computing systems. Furthermore, there’s no doubt left as to whether computing systems can generate such new patterns as to impact our own understanding of architecture. But even if computer algorithms can make possible the exploration of abstract alternatives to an abstract initial idea, as in Mathematica and Processing, the issue of relating abstract and geometric representations of human centered architecture lays in the hands of architects, programmers or, better yet, architect-programmers. What seems now to be the relevant change is that architectural design might escape from the traditional sequence embedded in the need – program – design iterations – solution timeline, substituted by a web of interactions among differing experimental paths, in which even the identification of needs is to be informed by computing. It is interesting to note that the computational approach to architectural design has been praised for the formal fluidity of bubbles and Bezier shapes it entails and for the overcoming of functionalist and serialization typical of modern architecture. That approach betrays a high degree of canonic fascination with the tools of the trade and very little connection to the day to day chores of building design. On the other hand, shall our new tools and toys open up new ways of thinking and designing our built landscape? What educational issues surface if we are to foster wider use of the existing technologies and simultaneously address the need to overtake mass construction? Is mass customization the answer for the dead end modern architecture has led us to? Can we let go the humanist approach begun in Renascence and culminated in Modernism or shall we review that approach in view of algorithmic architecture? Let us step back in time to 1726 when Swift’s ‘Travels into Several Remote Nations of the World by Lemuel Gulliver’ was first published. In Swift’s fierce critic of what seemed to him the most outrageous ideas, he conceived a strange machine devised to automatically write books and poetry, in much the same generative fashion that now, three centuries later, we begin to cherish. “Every one knew how laborious the usual method is of attaining to arts and sciences; whereas by his contrivance, the most ignorant person at a reasonable charge, and with a little bodily labour, may write books in philosophy, poetry, politicks, law, mathematics and theology, without the least assistance from genius or study. He then led me to the frame, about the sides whereof all his pupils stood in ranks. It was twenty foot square, placed in the middle of the room. The superficies was composed of several bits of wood, about the bigness of a dye, but some larger than others. They were all linked together by slender wires. These bits of wood were covered on every square with paper pasted on them; and, on these papers were written all the words of their language in their several moods, tenses, and declensions, but without any order. The professor then desired me to observe, for he was going to set his engine at work. The pupils at his command took each of them hold of an iron handle, whereof there were forty fixed round the edges of the frame; and giving them a sudden turn, the whole disposition of words was entirely changed. He then commanded six and thirty of the lads to read the several lines softly as they appeared upon the frame; and where they found three or four words together that might make part of a sentence, they dictated to the four remaining boys who were scribes. This work was repeated three or four times, and at every turn the engine was so contrived, that the words shifted into new places, as the square bits of wood moved upside down.” (Jonathan Swift, Gulliver’s Travels, A Voyage to Balnibarbi) What astonishing forecast did Swift show in that narrative that, in spite of the underlying incredulity and irony, still clarifies our surprise when faced to what might seem to some of us just an abandonment of all that architects and designers have cherished: creativeness and inventiveness. Yet, we could argue that such a radical shift in paradigm occurred once when master builders left the construction ground and took seat at drafting boards. The whole body of design and construction knowledge was split into what now seem to us just specialties undertaken by more and more isolated professionals. That shift entailed new forms of representation and prediction which now each and all architects take for granted. Also, Cartesian space representation turned out to be the main instrument for professional practice, even if one can argue that it is not more than the unfolding of stone carving techniques that master builders and guilds were so fond of. Enter computing and all its unfolding, i.e. DNA coding, fractal geometry, generative computing, nonlinear dynamics, pattern generation and cellular automata, as a whole new chapter in science, and compare that to conical perspective, descriptive and analytical geometry and calculus, and an image begins to form, delineating a separation between architect and digital designer. In previous works, we have tried approaching the issues regarding architects education in a more consensual way. But it seems now that the whole curricular corpus might be changed as well. The very foundations upon which we prepare future professionals shall change, not only in College, but in High School as well. In this paper, we delve further into the disconnect between current curricula and digital design practices and suggest new disciplinary grounds for a new architectural education.

summary	One of the primary features of solar passive design is the orientation of a building on a particular latitude. The client of Information Technology demands testing, validity, practicality and sustainability of a building project before execution. The computer based simulations are the only practical way to predict the complex energy performance and analysis for a large number of passive design solutions. This paper investigates the optimum residential building orientation having various zones, located in Lahore, Pakistan, with the help of Energy Simulation program. It is concluded that with the help of software, it is possible to orient the residential plan with the minimum solar gain of the required living zones.
