title Systematic approach to design builds for freeform façade: AFA Cultural Center
source SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 176-182
summary The design and construction of the complex, irregularly shaped, and curvilinear building forms are also known as freeform architecture, have gained an interest form architects and engineers. This paper presents how freeform façade designs are defined with its curvilinear geometric characteristics and the systematic approach that is used to design and implement them. The proposed method incorporates product design and integral façade construction approach at AFA Cultural Center freeform façade implementation. Therefore, the paper aims to improve the viability of the proposed method and decreasing the gap between the other disciplines and architects in a systematic way without losing the creativity of the architects.

title A Hypermedia Model for Supporting Energy Design in Buildings
source Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49
summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title Integrating Energy Design Into Caad Tools: Theoretical Limits and Potentials
source CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 323-340
summary The study is part of a research aims to establish theoretical grounds essential for the development of user efficient design tools for energy-conscious architectural design, based on theories in human factors of intelligent interfaces, problem solving, and architectural design. It starts by reviewing the shortcomings of the current energy design tools, from both architectural design and human factor points of view. It discusses the issues of energy integration with design from three different points of view: architectural, problem-solving, and human factors. It evaluates theoretically the potentials and limitations of the current approaches and technologies in artificial intelligence toward achieving the notion "integrating energy design knowledge into the design process" in practice and education based on research in the area of problem solving and human factors and usability concerns. The study considers the user interface model that is based on the cognitive approach and can be implemented by the hierarchical structure and the object-oriented model, as a promising direction for future development. That is because this model regards the user as the center of the design tool. However, there are still limitations that require extensive research in both theoretical and implementation directions. At the end, the study concludes by discussing the important points for future research.

summary The research presented here tests the capacity of artificial-neural-network (ANN) based multi-agent systems to be implemented in architectural design processes. Artificial Intelligence algorithms allow for a new approach to design, taking advantage of its generic functioning to produce meaningful outcomes. Experimentation within this project is based on Self-Organizing Maps (SOMs) and takes advantage of its behavior in topology to produce architectural geometry. SOMs as full stochastic processes involve randomness, uncertainty and unpredictability as key features to deal with during the design process. Following this behavior, SOMs are used to transmit information, which, instead of being copied, is reproduced after a learning (training) process. Pre-existent architectural objects are taken as learning models as they have been considered masterpieces. In this context, by defining the SOM input set, masterpieces become measurement elements and can be used to set a distance to the new element position in a comparatistic space. The characteristics of masterpieces get embedded within the code and are transmitted to 3D objects. SOM produced objects from a population with shared characteristics where the masterpiece position is its probabilistic center point.

summary Brazil has so many historical cities with important architectural heritage. Some of them are remains of the colonial times and aggregate beautiful buildings such as, palaces, public buildings and churches in baroque style, legacy of the Portuguese colonization. Despite of its cultural value, most of these building sets are under several kinds of threats. This paper discusses about the experience on digital photogrammetric restitution of the building façades of Pelourinho, a neighborhood in the historical center of Salvador, the capital city of the State of Bahia. The architectural documentation is an important way to preserve and safeguard its memory, besides being an effective educational process about the meaning of preservation and cultural heritage.

summary This paper describes the Pelourinho Project realized past July in Salvador, during the 1st International Conference on 3D Laser Scanning for Heritage Documentation. The Pelourinho located at the historic center of Salvador, is an impressive wide set of buildings listed by UNESCO as World Heritage. The text contains a quickly overview about the 3D laser scanning technology, shows how data are captured and what they stored and what they means. The 3D laser scanning model, another kind of 3D geometric model is called point cloud and represents an excellent way to store data of some particular constructions. Because its irregular shapes it is very arduous to survey and represent these constructions by any other method. The point cloud model is an excellent way to represent with integrity and accuracy these particular complex shapes like the colonial baroque churches in Brazil. [Full paper in Portuguese]

title Let's Improvise Together
source International Conference on Generative Art
summary The creators of ‘Let's-Improvise-Together’ adhere to the idea that while there is a multitude of online games now available in cyberspace, it appears that relatively few are focused on providing a positive, friendly and productive experience for the user. Producing this kind of experience is one the goals of our Amusement Project.To this end, the creation of ‘Let's Improvise Together’ has been guided by dedication to the importance of three themes:* the importance of cooperation,* the importance of creativity, and* the importance of emotion.Description of the GameThe avatar arrives in a certain area where there are many sound-blocks/objects. Or he may add sound "property" to existing ones. He can add new objects at will. Each object may represents a different sound, they do not have to though. The avatar walks around and chooses which objects he likes. Makes copies of these and add sounds or change the sounds on existing ones, then with all of the sound-blocks combined make his personalized "instrument". Now any player can make sounds on the instrument by approaching or bumping into a sound-block. The way that the avatar makes sounds on the instrument can vary. At the end of the improvising session, the ‘composition’ will be saved on the instrument site, along with the personalized instrument. In this way, each user of the Amusement Center will leave behind him a unique instrumental creation, that others who visit the Center later will be able to play on and listen to. The fully creative experience of making a new instrument can be obtained connecting to Active Worlds world ‘Amuse’ and ‘Amuse2’.Animated colorful sounding objects can be assembled by the user in the Virtual Environment as a sort of sounding instrument. We refrain here deliberately from using the word musical instrument, because the level of control we have on the sound in terms of rythm and melody, among other parameters, is very limited. It resembles instead, very closely, to the primitive instruments used by humans in some civilizations or to the experience made by children making sound out of ordinary objects. The dimension of cooperation is of paramount importance in the process of building and using the virtual sounding instrument. The instrument can be built on ones own effort but preferably by a team of cooperating users. The cooperation has as an important corolary: the sharing of the experience. The shared experience finds its permanence in the collective memory of the sounding instruments built. The sounding instrument can be seen also as a virtual sculpture, indeed this sculpture is a multimedial one. The objects have properties that ranges from video animation to sound to virtual physical properties like solidity. The role of the user representation in the Virtual World, called avatar, is important because it conveys, among other things, the user’s emotions. It is worth pointing out that the Avatar has no emotions on its own but it simply expresses the emotions of the user behind it. In a way it could be considered a sort of actor performing the script that the user gives it in real-time while playing.The other important element of the integration is related to the memory of the experience left by the user into the Virtual World. The new layout is explored and experienced. The layout is a permanent editable memory. The generative aspects of Let's improvise together are the following.The multi-media virtual sculpture left behind any participating avatar is not the creation of a single author/artist. The outcome of the sinergic interaction of various authors is not deterministic, nor predictable. The authors can indeed use generative algorythm in order to create the texture to be used on the objects. Usually, in our experience, the visitors of the Amuse worlds use shareware programs in order to generate their texture. In most cases the shareware programs are simple fractals generators. In principle, it is possible to generate also the shape of the object in a generative way. Taking into account the usual audience of our world, we expected visitors to use very simple algorythm that could generate shapes as .rwx files. Indeed, noone has attempted to do so insofar. As far as the music is concerned, the availability of shareware programs that allow simple generation of sounds sequences has made possible, for some users, to generate sounds sequences to be put in our world. In conclusion, the Let's improvise section of the Amuse worlds could be open for experimentation on generative art as a very simple entry point platform. We will be very happy to help anybody that for educational purposes would try to use our platform in order to create and exhibit generative forms of art.

title Crowdsourcing the Obama Presidential Center: An Alternative Design Delivery Model: Democratizing Architectural Design

summary In this article, we present crowdsourcing as a design delivery method for publicly funded buildings, and compare it to the traditional Request for Proposals (RFP). We explore the potential of crowdsourcing through the use of an online design competition for the Obama Presidential Center in Chicago, IL, which the authors administered at, a crowdsourcing platform. Competition procedures have been applied in architectural practice since antiquity, from the Parthenon and the Hagia Sophia to thousands of seminal buildings around the globe. However, with the advent of digital technologies and outreach to a more interconnected world, crowdsourcing allows even the most mundane design challenges to go through the fair competition protocol. We argue that crowdsourcing can help democratize architectural design acquisition by giving a level playing field to designers, and produce a more just, competitive, and creative design product.

summary Architectural surfaces constantly emit radiant heat fluxes to their surroundings, a phenomenon that is wholly dependent on their geometry and material properties. Therefore, the capacity of 3D scanning techniques to capture the geometry of building surfaces should be extended to sense and capture the surfaces’ thermal behavior in real time. We present an innovative sensor, SMART (Spherical-Motion Average Radiant Temperature Sensor), which captures the thermal characteristics of the built environment by coupling laser geometry scanning with infrared surface temperature detection. Its novelty lies in the combination of the two sensor technologies into an analytical device for radiant temperature mapping. With a sensor-based dynamic thermal-surface model, it is possible to achieve representation and control over one of the major factors affecting human comfort. The results for a case-study of a 3D thermal scan conducted in the recently completed Lewis Center for the Arts at Princeton University are compared with simulation results based on a detailed BIM model of the same space.

summary Architectural education has often been criticised for producing students that seem to lack the practical knowledge needed to create architecture that is fit for purpose, safe and a delight to users. Unfortunately, owing to the complexities of society, technology, practice and academia, design teachers are struggling to balance the teaching of basic practical concerns for making architecture with teaching students how to think critically and abstractly. This paper suggests a resolution that places the computer at the center of the relationship between student and tutor. It suggests a digital teaching tool that detects and interprets the marks students make when sketching. The digital design coach then presents the student with related issues allowing a comprehensive reading of the digital sketch. The student, more aware of the issues involved, engages in more intelligent and wellinformed dialogue with tutor.

summary A well-known job shop scheduling problem can be formulated as follows. Given a graph G with node set N and with directed and undirected arcs, find an orientation of the undirected arcs that minimizes the length of a longest path in G. The author treats the problem as a disjunctive program, without recourse to integer variables, and give a partial characterization of the scheduling polyhedron P(N), i.e., the convex hull of feasible schedules. In particular, he derives all the facets inducing inequalities for the scheduling polyhedron P(K) defined on some clique with node set K, and gives a sufficient condition for such inequalities to also induce facets of P(N). One of our results is that any inequality that induces a facet of P(H) for some HCK, also induces a facet of P(K). Another one is a recursive formula for deriving a facet inducing inequality with p positive coefficients from one with p-1 positive coefficients. The author also addresses the constraint identification problem, and gives a procedure for finding an inequality that cuts off a given solution to a subset of the constraints
