title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Further Automatic Breakbeat Cutting Methods
source	International Conference on Generative Art
summary	Following the invention of an automatic breakbeat cutting algorithm in the style of early 90s jungle, further experiments are described. These are namely, the use of more advanced techniques to control choices in the original algorithm, and new algorithms for cutting including methods based on campanology and recursion. Automatic breakbeat cutting can reduce the effort of working by hand in a sequencer with MIDI triggering of a sampler. Furthermore, the parameterisation of the process concedes newtechniques that can be awkward to implement with a sequencer, for example, cutting in septuplet demisemiquavers. To improve the original algorithm, states, whether offsets, cut sizes or repetition counts, canbe governed by Charles Ames' method of statistical feedback. Weight distributions can be changed during a phrase to give more control of cut sequence structure. These processes are investigated in the light of the output pacing and variation of cut sequences. Campanology, or change ringing, is based on a small subset of a permutation group consistingof permutations that can only swap adjacent elements in distinct pairs. When acting upon offsets into the source a fluid series of undulating cuts can be produced. Recursive cutting is an analytical test of second order cutting. It takes a base sequence of [cut length, offset] pairs and further cuts them up, producing variations on a given cut sequence. The Warp Cutter is inspired by the thought of constant stutters and rolls. Probabilities control the likelihood of simple blocks, even rolls or geometric accelerating rolls, usually at very fast repetition rates. All methods have been implemented as SuperCollider patches and classes, and publiclyreleased to accompany this paper in the BBCut Library.

title	Performance-based computational design via differential modeling and two-staged mapping
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 667-680
summary	Computational performance-based building design support faces a conflict. It is important to provide building performance feed back to the designer as early as possible in the design process. But many aspects of building performance are significantly affected by the design of the building’s technical systems, which are typically configured in detail only in the later stages of design. The challenge is thus to find a method to use detailed simulation tools even during the early stages of design when values for many of the variables for the building’s technical sub-systems are not yet available. In this paper, we demonstrate how this problem can be partially solved by combining two levels of automation. The first level consists of differential building representation involving a number of domain (application-specific) object models that are derived from a shared object model automatically. The second level uses generative agents that create reference designs for the technical sub-systems of the building. To demonstrate the feasibility of the proposed approach, we use the building energy systems domain (heating, cooling, ventilation, and air-conditioning) as a case in point.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2016.140
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. 140-151
summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	Artificial intelligence in architecture: Generating conceptual design via deep learning
source	International Journal of Architectural Computing vol. 16 - no. 4, 306-327
summary	Artificial intelligence, and in particular machine learning, is a fast-emerging field. Research on artificial intelligence focuses mainly on image-, text- and voice-based applications, leading to breakthrough developments in self-driving cars, voice recognition algorithms and recommendation systems. In this article, we present the research of an alternative graph- based machine learning system that deals with three-dimensional space, which is more structured and combinatorial than images, text or voice. Specifically, we present a function-driven deep learning approach to generate conceptual design. We trained and used deep neural networks to evaluate existing designs encoded as graphs, extract significant building blocks as subgraphs and merge them into new compositions. Finally, we explored the application of generative adversarial networks to generate entirely new and unique designs.

title	A Remote Sharing Method of 3D Physical Objects Using Instance-Segmented Real-Time 3D Point Cloud for Design Meeting
doi	https://doi.org/10.52842/conf.caadria.2022.2.395
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 395-404
summary	In the field of architecture and urban design, physical models are used in design meetings. Furthermore, teleconferencing via the internet has begun to be widely used in society due to COVID-19 and in preparation for disasters. Although conventional web conferencing can share only 2D information through screens, it is expected that interactive screen sharing of physical objects will enable smoother remote conferencing. A system that can manipulate point clouds in clusters by dividing real-time point clouds captured from 3D real objects by distance has been reported as a way to share physical objects. However, because the point clouds are divided by distance between the two clusters when the point clouds get closer than some threshold, they become treated as a single object. In this study, we aim to develop a system that uses instance segmentation to divide point clouds by region rather than by distance between objects. This system is expected to contribute to the realisation of better architectural and urban design processes without any misunderstandings among the parties involved and to the reduction of unnecessary energy consumption due to travel for face-to-face meetings.

title	Land Use Type Allocation Informed by Urban Energy Performance: A Use Case for a Semantic-Web Approach to Master Planning - A USE CASE FOR A SEMANTIC-WEB APPROACH TO MASTER PLANNING

summary	Cities are growing fast and facing unprecedented challenges as urban populations grow and resources are becoming scarce. A citys master planning involves a series of decision-making processes and requires knowledge from various domains. Urban planners are seeking computational support. We present a use case of land use type or building function allocations informed by urban energy performance as a pilot demonstrator for a semantic-web approach to these challenges. The software used for energy performance assessment was the City Energy Analyst. Using a quarter in downtown Singapore as an example, the results indicated 70% to 80% residential supplemented by other land use types favours efficient use of district cooling systems and photovoltaic panels. Urban planners may use the results to narrow down the search space of land use type ratios for the selected mixed-use area in Singapore. The use case serves as a pilot demonstrator for a broader research scope, the project Cities Knowledge Graph. To support master planning, the project aims to build an extendable plat-form to integrate more datasets and evaluation software for various urban qualities and domains.

title	Architectural synthesis and optimization of digital systems
source	Eindhoven University of Technology
summary	High level synthesis means going from an functional specification of a digits-system at the algorithmic level to a register transfer level structure. Different appli-cations will ask for different design styles. Despite this diversity in design styles many tasks in the synthesis will be similar. There is no need to write a new synthesis system for each design style. The best way to go seems a decomposition of the high level synthesis problems in several well defined subproblems. How the problem is decomposed depends heavily on a) the type of network architecture chosen, b) the constraints applied to the design and c) on the functional description itself. From this architecture style, the constraints and the functional description a synthesis scheme can be derived.Once this scheme is fixed, algorithms can be chosen which fit into this scheme and solve the subproblems in a fast and, when possible, optimal way. To support such a synthesis philosophy, a framework is needed in which all design information can be stored in a unique way during the various phases of the design process. This asks for a design data base capable of handling all design information with a formally defined interface to all design tools. This thesis gives a formal way to describe both the functional representation, the register transfer level structure and the controller and the relations between all three of them. Special attention has been paid to the efficient representation of mutual exclusive operations and array accesses. The scheduling and allocation problems are defined as mappings between these formal representations. Both the existing synthesis algorithms and the new algorithms described in this thesis fit into this framework. Three new allocation algorithms are presented in this thesis: an algorithm for optimal register allocation in cyclic data flow graphs, an exact polynomial algorithm to do the module allocation and a new scheme to minimize the number of interconnections during all stages of the data path allocation. Cyclic data flow graphs result from high level behavioral descriptions that contain loops. Algorithms for register allocation in high level synthesis published up till now, only considered loop free data flow graphs, When these algorithms are applied to data flow graphs with loops, unnecessary register transfer operations are introduced. A new algorithm is presented that performs a minimal register allocation and eliminates all superfluous register transfer operations. The problem is reformulated as a multicommodity network flow problem for which very efficient solutions exist. Experiments on a benchmark set have shown that in all test cases all register transfers could be eliminated at no increase in register cost. Only heuristic algorithms appeared in literature to solve the module allocation problem. The module allocation problem is usually defined as a clique cover problem on a so-called module allocation graph. It is shown that, under certain conditions, the module allocation graph belongs to the special class of comparability graphs. A polynomial time algorithm can optimally find a clique cover of such a graph. Even when interconnect weights are taken into account, this can be solved exactly. This problem can be transformed into a maximal cost network flow problem, which can be solved exactly in polynomial time. An algorithm is described which solves the module allocation problem with interconnect weights exactly, with a complexity O(kn2), where n is the number of operations In previous research, interconnection was optimized when the module allocation for the operations and the register allocation for the variables already had been done. However, the amount of multiplexing and interconnect are crucial factors to both the delay and the area of a circuit. A new scheme is presented to minimize the number of interconnections during the data path allocation. This scheme first groups all values based on their read and write times. Values belonging to the same group can share a register file. This minimizes the number of data transfers with different sources and destinations. Secondly, registers are allocated for each group separately. Finally the interconnect allocation is done. During the interconnect allocation, the module allocation is determined. The value grouping is based on edge coloring algorithms providing a sharp upper bound on the number of colors needed two techniques: splitting read and write phases of values and introducing serial (re-)write operations for the same value, make that even more efficient exact edge coloring algorithms can be used. It is shown that when variables are grouped into register files and operations are assigned to modules during the interconnection minimization, significant savings (20%) can be obtained in the number of local interconnections and the amount of global interconnect, at the expense of only slightly more register area.

summary	Traditionally, architects express their thoughts on the design of 3D architectural forms via perspective renderings and standardized 2D drawings. However, as architectural design is always multidimensional and intricate, it is difficult to make others understand the design intention, concrete form, and even spatial layout through simple language descriptions. Benefiting from the fast development of machine learning, especially natural language processing and convolutional neural networks, this paper proposes a Linguistics-based Architectural Form Generative Model (LAFGM) that could be trained to make 3D architectural form predictions based simply on language input. Several related works exist that focus on learning text-to-image generation, while others have taken a further step by generating simple shapes from the descriptions. However, the text parsing and output of these works still remain either at the 2D stage or confined to a single geometry. On the basis of these works, this paper used both Stanford Scene Graph Parser (Sebastian et al. 2015) and graph convolutional networks (Kipf and Welling 2016) to compile the analytic semantic structure for the input texts, then generated the 3D architectural form expressed by the language descriptions, which is also aided by several optimization algorithms. To a certain extent, the training results approached the 3D form intended in the textual description, not only indicating the tremendous potential of LAFGM from linguistic input to 3D architectural form, but also innovating design expression and communication regarding 3D spatial information.

title	AVOCAAD - A First Step Towards Distance Learning?

summary	In the industrial world knowledge is developed very fast. As most countries are depending on employees with a high level of knowledge and skills the term ”Life Long Learning” has been formulated and the concept is more and more accepted. Institutions of higher education are more and more involved in creating supplementary education more independent of time and place. Distance learning was originally carried out by ordinary mail, which was slow but might then have been the only solution for people in remote places. With the Internet and e-mail the distance-learning concept has got a far better tool, for instance better interaction facilities. Architects and engineers in practise are deeply involved in solving the problems of the present projects. Education which is independent of time and place must be of great interest to both parties. The AVOCAAD project has created an education model for students to meet the possibilities of CAAD. The education model can be used in a curriculum at a school as well as for distance learning. Among the possible experiences from it, the one concerning distance learning might be the most important future application of the system in architectural education. This paper sketches the pedagogical background and gives examples from other areas of knowledge, where distance learning is already in use. We will put the question how the AVOCAAD concept meets the experiences from distance learning.

summary	Thank you to the ACADIA team for extending the invitation to come here. For me, it's a really fantastic moment to reconnect with the ACADIA community. I've been dipping in and out of it since -- I think my first ACADIA was in Savannah, Georgia. Does anyone remember what year that was? 2001? 2002? I've been dipping in and out. And I really see this community as a model. You know, we could talk about the Mississippi and how it meanders, and passages of energy and matter and information begin to change. And the ACADIA community meanders across these different territories, but somehow it maintains its particular identity. And that identity, I think, is shrouded within ideals of sharing -- knowledge sharing -- and within a kind of creative design research, you know, rigor, which I find really fascinating.

title	Spatial Orientation in Virtual Environments
source	Delft University of Technology
summary	Recently, a growing interest can be detected in the application of Virtual Environment (VE) technology as an operator interface. VEs are three-dimensional computer-generated images that can be shown on a conventional monitor, on a large screen display, or on a head-mounted display. In order to use these three-dimensional interfaces for finding and retrieving information, the user must be able to spatially orient themselves.Different types of VE technology are available for navigating in these VEs, and different types of navigation can be enabled. A choice has to be made between the different options to enable good spatial orientation of the user. There are two main types of VE interfaces: an immersive interface that provides rich sensory feedback to the user when moving around in the VE, and a non-immersive interface that provides only visual feedback to the user when moving around in the VE. Furthermore, navigation through the VE can either be continuous providing fluent motion, or can be discontinuous which means that the viewpoint is displaced instantaneously over a large distance.To provide insight into the possible effects of these options a series of nine experiments was carried out. In the experiments the quality of spatial orientation behaviour of test subjects is measured while using the different types of interface and the different types of navigation.The results of the experiments indicate that immersive navigation improves the perception of displacement through the VE, which in turn aids the acquisition of spatial knowledge. However, as soon as the spatial layout of the VE is learned the two types of navigation interface do not lead to differences in spatial orientation performance. A discontinuous displacement leads to temporary disorientation, which will hinder the acquisition of spatial knowledge. The type of discontinuous displacements has an effect on the time needed for anticipation. The disorienting effects of a discontinuous displacement can be compensated for by enabling cognitive anticipation to the destination of the displacement.These results suggest that immersive navigation might only be beneficial for application domains in which new spatial layouts have to be learned every time or in domains where the primary users are novices. For instance, in training firemen to teach them the layout of new buildings with VE, or in using architectural walkthroughs in VE to show new building designs to potential buyers. Discontinuous movement should not be allowed when exploring a new environment. Once the environment is learned and if fast displacement is essential then discontinuous displacement should be preferred. In this case, the interface designer must make sure that information is provided about the destination of a discontinuous displacement.

summary	It has been designed and developed a system Web that has video in real time and an interactive product catalogue based on pseudo-three-dimensional models, that is to say, models that they pretend to be three-dimensional, but that in fact do not have geometry 3D properly in the memory, but of an appropriate composition according to the case of geometry 2D (image or any graph), that allows to see the model from several points of view and to consult additional information (weight, material, dimensions, etc.). They have been analyzed and proven the different formats from transmission of video and audio by Internet, studying all its parameters, until finding the optimal ones for this server. In comparison with the use of format VRML (Virtual Reality Modeling Language) used commonly to put models 3D in the Web, this system that we have devised presents like advantages the low time of load, the high precision of the views of the object and the low cost of maintenance of the Web. On the other hand, one does not have the infinity of views and facility of manipulation of the VRML.

A research group has been established to investigate and explore a particular aspect of this new potential with the goal of creating an eCAADe Virtual world as a vehicle for testing the associated ideas. This papers reports on the recent developments on this project.

title	Architectural critique through digital scenariobuilding. Augmenting Architectural Criticism and Narrative
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 697-709
summary	As an idea scenario-building has parallels the use of creative faking in related disciplines, most particularly, in contemporary art. The techniques involved in scenario-building and faking offer us enhanced ways of undertaking creative thinking and critical review of architecture and architectural projects. Critical review and theoretical analysis of architecture can be undertaken via a range of methods that Attoe (1978) classifies as Normative, Interpretive and Descriptive. Digital representation now offers us new ways of augmenting these critical styles in ways that have yet to be fully exploited, and possible means of exploitation are illustrated in this paper. In short the work described here shows how digital techniques can be used to enrich architectural investigation, critical reporting and debate.

title	Interactive Walkthrough Environments for Simulation
source	University of California at Berkeley
summary	This thesis describes a second-generation walkthrough framework that provides extensive facilities for integrating many types of third-party simulation codes into a large-scale virtual environment model, and puts it in perspective with first-generation systems built during the last two decades. The framework provides an advanced model database that supports multiple simultaneous users with full consistency semantics, system independent storage and retrieval, and efficient prefetching and object reconstruction techniques to support second and third-generation walkthrough systems. Furthermore, our framework integrates support for scalable, distributed, interactive models with plug-in physical simulation to provide a large and rich environment suitable for architectural evaluation and training applications. A number of third-party simulations have been integrated into the framework, including dynamic physical interactions, fire simulation, multiple distributed users, radiosity, and online tapestry generation. All of these simulators interact with each other and with the user via a data distribution network that provides efficient, optimized use of bandwidth to transport simulation results to clients as they need them for visualization. These diverse simulators provide proof of concept for the generality of the framework, and show how quickly third-party simulations can be integrated into our system. The result is a highly interactive distributed architectural model with applications in research, training, and real-time data visualization. Finally, an outlook is given to a possible third generation of virtual environment architectures that are capable of integrating different heterogeneous walkthrough models.

title	Sagrada Família Rosassa: Global Computeraided Dialogue between Designer and Craftsperson (Overcoming Differences in Age, Time and Distance)
doi	https://doi.org/10.52842/conf.acadia.2001.076

summary	The rose window (‘rosassa’ in Catalan) recently completed between the two groups of towers that make up the Passion Façade of Gaudí’s Sagrada Família Church in Barcelona measures eight metres wide and thirty-five metres in height [Figure 1]. There were four phases to the design based in three distinct geographical locations. The design was undertaken on site, design description in Australia some eighteen thousand kilometres distant, stone-cutting a thousand kilometres distant in Galicia, with the completion of the window in March 2001. The entire undertaking was achieved within a timeframe of fifteen months from the first design sketch. Within this relatively short period, the entire team achieved a new marriage between architecture and construction, a broader relationship between time-honoured craft technique with high technology, and evidence of leading the way in trans-global collaboration via the Internet. Together the various members of the project team combined to demonstrate that the technical office on site at the Sagrada Família Church now has the capacity to use ‘just-in-time’ project management in order to increase efficiency. The processes and dialogues developed help transcend the tyranny of distance, the difficult relationship between traditional craft based technique and innovative digitally enhanced production methods, and the three generational age differences between the youngest and more senior team members.

title	DesignBUF: Exploring and Extending 2D Boolean Set Operations with Multiple Modes in the Early Design Phase
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 589-602
summary	Boolean set operations have been a powerful design function set for any CAD systems including 2D and 3D domains. Their capacity to provide even more powerful design tools have not, however, been fully explored in the 2D system. The purpose of this study is to further explore 2D Boolean set operations with multiple modes, which include a pick mode, a wait mode, a drag-and-drop mode, and a draw-and-action mode. We develop a prototype design tool, called DesignBUF. It introduces a new concept of “design object buffer,” an intermediate design zone in which a designer freely sketches his/her design with design objects in a brainstorming fashion since valuable design ideas are ephemeral? and the designer needs to generate design schemes rapidly before the ideas disappear or are forgotten. After finishing such fast brainstorming processes, especially in the early design phase, the designer gets a stable and refined form of a floor plan, which in turn becomes a well structured form to maintain building and design information systematically. Therefore, the designer keeps switching back and forth between the “design object buffer” and structured floor plans. We believe that this dual working memory will not only increase system flexibility, but also reduce computation with unnecessarily complex design objects. This study also develops a robust algorithm to transform the intermediate design objects into a well-structured floor plan. In fact, the algorithm is also used for the extended Boolean set operations described above. A structured floor plan can also be transformed into non-structured forms. Research issues for future development are also identified at the end of the paper.

doi	https://doi.org/10.52842/conf.ecaade.2001.138
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 138-143
summary	The first implementation of the system MEA for building spatial and structural modeling and energy analysis using integrated graphical digital models in tuition of architecture students is being described. Working at different design stages and with various types of models the aim was to deliver the understanding of CAD tools as intelligent rather than pure technical ones.
