summary What sort of interfaces will allow, in the future, to manage the evolution of information and knowledge generation? What new scenarios would emerge in contemporary architecture when the access to a multidimensional architectural database is open and it is written and visited by anyone, anywhere in earth? Internet evolution is fast and unpredictable, propelling deep changes at different levels of our society. Spinoffs, unexpected outcomes are result of those changes, unfolding uncertain, unstable scenarios. This paper discusses the question of what could be the way to organize the process of registering, documenting and online publishing, native digital, three-dimensional content of Architecture, assuming the critical issue of information integration.

title Catoptric Surface
source ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 216-225
summary The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

title Living on the Edge - Reinventing the amphibiotic habitat of the Mesopotamian Marshlands
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 513-526
summary The Mesopotamian Marshlands form one of the first landscapes where people started to transform and manipulate the natural environment in order to sustain human habitation. For thousands of years, people have transformed natural ecosystems into agricultural fields, residential clusters and other agglomerated environments to sustain long-term settlement. In this way, the development of human society has been intricately linked to the extraction, processing and consumption of natural resources. The Mesopotamian Marshlands, located in one of the hottest and most arid areas on the planet, formed a unique wetlands ecosystem, which apart from millions of people, sustained a very high number of wildlife and endemic species. Several historical, political, social and climatic changes, which densely occurred during the past century, completely destroyed the unique civilisation of the area, made all the wild flora and fauna disappear and forced hundreds of thousands of people to migrate. During the last decade, many efforts have been made to restore the marshlands. However, these efforts are lacking a comprehensive design strategy, coherent goals and deep understanding of the complex current geopolitical situation, making the restoration process an extremely difficult task. This work aims at providing strategies for recovering the Mesopotamian Marshlands, organising productive functions in order to sustain the local population and design a new inhabitation model, using advanced computational tools while taking into account the extreme climatic conditions and several unique cultural aspects. Part of the aim of this work is to advance the use of computation and explore the opportunities that digital tools afford in helping find solutions to complex design problems where various design variables need to be coordinated to satisfy the design goals. Today, advanced computation enables designers to use population consumption demands, ecological processes and environmental inputs as design parameters to develop more robust and resilient regional planning strategies. This work has the double aim of first, presenting a framework for re-inhabiting the Marshlands of Mesopotamia. Second, the work suggests a design methodology based on computer-aided design for developing and organising productive functions and patterns of human occupation in wetland environments.

title Algorithmic investigation of the actual and virtual design space of historic hexagonal-based Islamic patterns
source International Journal of Architectural Computing vol. 16 - no. 1, 34-57
summary This research challenges the long-standing paradigm that considers compositional analysis to be the key to researching historical Islamic geometric patterns. Adopting a mathematical description shows that the historical focus on existing forms has left the relevant structural similarities between historical Islamic geometric patterns understudied. The research focused on the hexagonal-based Islamic geometric patterns and found that historical designs correlate to each other beyond just the formal dimension and that deep, morphological connections exist in the structures of historical singularities. Using historical evidence, this article identifies these connections and presents a categorization system that groups designs together based on their “morphogenetic” characteristics.

title Experiments as Modus Operandi
source Journal of Architectural Education. November, 1990. Vol. 44: pp. 37-48 : 9 p. of ill
summary Architecture has for too long focused on the presentation of pristine objects and the presentation in drawing form. A critical understanding of the field, however, necessitates a reevaluation of the roles of the process involved in the production of building. Rather than emphasizing surface appearances, an architecture rooted in process aims ultimately at revealing the fundamental and deep structures inherent within the making of architecture. One of the primary tasks of the process is to provoke intuition and ingenuity - and the awareness that both are founded on knowledge - and that knowledge must be applied with imagination. The experiment presented here developed sequentially with a defined structure to the process of design, moving gradually from the abstract into the concrete, thereby attempting and understanding of what Roland Barthes identified as 'concrete abstraction.'

title An Integrated 3D Geodatabase for Palladio's Work
source International Journal of Architectural Computing vol. 8 - no. 2, 111-133
summary The paper presents a novel digital 3D GIS web-based system entirely founded on Google Earth, built to offer a deep insight into Palladio's opera for restitution of its architectural surveys, reconstruction for historical reasons, analysis for structural and other options, and assembly and presentation of all certified Palladian documentation.The development of the application follows the philosophy of visual computing and it is based on an architectural knowledge representation.The information system is conceived as a typical Rich Internet Application and it is based on the digitalization of the complete Palladian corpus documentation implemented by the Centro Internazionale di Studi di Architettura Andrea Palladio (CISAAP).The 3D geodatabase system is, actually, in use at the Centro as the Palladian information system for researchers and in two expositions at Barbaran da Porto Palace in Vicenza, and at Villa Poiana at Poiana Maggiore, where is widely used by tourists for virtual visits to Palladian buildings.

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 Making Sense of Agent-based Simulation: Developing Design Strategy for Pedestrian-centric Urban Space
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 343-352
summary This study investigates the relationships of field observa- tion, multi-agent simulation and space-syntax theory in spatial config- uration for developing design strategy for a case study, a tourist hub area in Musi Riverside, Palembang. Having such potential advantage and to tackle existing social and urban issues, our study developed a design approach based on multi-agent simulation enhanced by space syntax theory. The goal of this study is a deep understanding of multi agent simulation through mechanism of validation using field obser- vation and by taking into account the existing urban features. The purpose is to develop design strategy of pedestrian-centric urban space to be functioned as a tourist hub based on computational modelling. Following the paths result of pedestrian flow by multi-agents simula- tion, we elaborated the analysis of facility programming by means of Space Syntax theory. It shows the ranking of facility programs based on their relative connectivity and integration. By merging this result, it assembles programs and their circulation spaces by means of compu- tational simulation. Experimenting in both fields show a novel ap- proach for pedestrian-centric design in urban scale, particularly since behavioural models rarely used in early stage of design process. It shows that multi-agent simulation should be coupled with field obser- vation.

title Emerging Technololgy – Dilemma and Opportunities in Housing
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary Digital Technology has transformed industrial manufacturing and production; and an array of Industrial Design products provide increasing comfort and benefit to millions of global citizens via ergonomic and mass production/customization strategies. Yet, housing needs of a rapidly growing global population are rarely affected by digital technology. Shifts in societal demographics, from rural to urban city centres, and concurrently Global Warming and ecological changes are exacerbating the world housing situation. Millions are homeless, live in inadequate shelter, or as in the US Manufactured Housing (MH) market, live in nondurable poor quality “manufactured” houses that are detrimental to health, at best, or during extreme weather events, suffer catastrophic damages often resulting in death to occupants. Nevertheless, housing concepts and related living units have benefited very little when compared to architecture’s related manufacturing industries counter-parts (i.e. automotive, aerospace, marine industries, etc). While Technology has vividly expanded the shape language of architecture (i.e. Free-Form-Design), some may argue that Free-Form- Design buildings generally have beauty that is only “skin deep” and typically focus on providing signature statements for both the designer and elite clientele. In this paper, we will briefly review the role of the architect in the US Manufactured Housing industry; additionally, we will identify the major problems that plaque the US Manufactured Housing Industry. Further, we will review how architects and Industrial Designers use technology in their respective fields and draw larger designmanufacture principals for issues of global housing. Our findings and analysis suggest that an Industrial Design approach, applied in architecture for mass housing, offers a means of improving the architect’s role and technology in manufactured housing for the masses.

title Childishly Honest Associate of the Trickery
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 209-219
summary Perspective is a method of presentation of 3- dimensional space on the 2-dimensional surface. It can only approximately express the complexity of the authentic perception of reality. During the centuries canons of presentation varied in different epochs. It is quite possible that conventions of presentation considered today as exact expressions of reality may seem for the future generations as untrue as the ancient Egypt paintings seem for us. Our mind plays the major role in all kinds of presentation. During the whole life we learn to perceive the surrounding reality. We have formed also ability to ,see" the perspective. The linear perspective is not so easy in perception without factors of colour and light. These factors play a very important role in perception of the distance. The perception of perspective is not always unmistakable. Introduction of light and shadow is one of the measures to limit the ambiguity. Objects shown in perspective with appropriately chosen colouring and light-and-shade effects reveal impression of the distance inside the flat picture. Illusions of perspective are most astonishing when one can assume deep-rooted expectations and suppositions of the addressee. The computer monitor, like the picture, has only one plane on which our project can be presented. The major feature of architecture programs is both the possibility of creating various architecture spaces and the possibility to examine how (in our opinion) the created space would affect the addressee. By means of computer programs we are able to generate drawings and objects of two kinds: first - being the ideal projection of reality (at least in the same measure as the photograph), and the second - being the total negation of perspective rules. By means of CAD programs enabling 3-dimensional job we can check how all sorts of perspective tricks and artifices affect our imagination. The program cooperates with us trying to cheat the imperfect sense of sight. The trickeries can be of various type, starting from play of lights, through the elements changing the perception of perspective, and terminating with objects totally negating the rules of sound construction of solids. The knowledge contained in these programs is an encyclopaedic recapitulation of all sorts of achievements in the field of perspective and application of colour and light effects. All that remains to the users is to exploit this tremendous variety of capabilities.

title Strategic Urban Planning in the Netherlands
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Since the mid-1980s, several Dutch towns have initiated many urban planning and design activities for their existing area. This represented a shift in that previous urban planning projects typicallyconcerned expansion in the outskirts of the city, or urban renewal. The complex and expensive renovation of the existing housing stock rarely allowed a deep interest in urban design. Since 1985, attention shifted from the housing stock to the city as a whole. Furthermore, public andprivate actors increasingly become involved in the planning process. It became clear that a more comprehensive plan for the whole existing town or region was needed. Conventional planning instruments were considered ill-suited for this new challenge. The paper discusses promising attempts of various urban planning instruments to get a stronger but also more flexible hold on thetransformation of the urban planning area in the Netherlands. These new planning instruments have three common characteristics: (i) they give special attention to the different levels of urban management needed for different urban areas, (ii) these strategic plans provide an integral view on the urban developments, and (iii) these plans introduce a new strategy to deal with both private initiatives to transform urban sites and monitor wishes, proposals, etc. from inhabitants in the neighbourhoods. A comparative analyses of several cities indicates, however, that, in addition to these common characteristics, major differences between their strategic plans exist depending upon their historic patrimonium, economic status and planning tradition.

title The Virtual Cathedral - An Essay about CAAD, History and Structure

summary The Old Cathedral of Santa Maria in Vitoria is the most representative building of the Gothic style in the Basque Country. Built during the XIV century, it has been closed to the cult in 1994 because of the high risk of collapse that presents its structure. This closure was originated by the structural analysis that was entrusted to the University of the Basque Country in 1992. The topographic works developed in the Cathedral to elaborate the planimetry of the temple revealed that many structural elements of great importance like arches, buttresses and flying buttresses were removed, modified or added along the history of Santa Maria. The first structural analysis made in the church suggested that the huge deformations showed in the resistant elements, specially the piers, were originated by interventions made in the past. A deep historical investigation allowed us to know how the Cathedral was built and the changes executed until our days. With this information, we started the elaboration of a virtual model of the Cathedral of Santa Maria. This model was introduced into a Finite Elements Method system to study the deformations suffered in the church during its construction in the XIV century, and the intervention made later in the XV, XVI and XX centuries. The efficiency of the virtual model simulating the geometry of the Cathedral along history allowed us to detect the cause of the structural damage, that was finally found in many unfortunate interventions along time.

summary New technologies and uncontrolled open-data policies lead public to a new way of approaching the built environment. To enlarge the competences of the professionals that work within the cities, we believe that providing a deep and dynamic knowledge on the heritage and urban built environment is the more effective solution to offer a unique support to the needs. By providing a boosted geographical database with detailed information about the status of each building, we aim to support the professional by providing a neat vision about vacant buildings available citywide. We think this knowledge is an important asset in covering every kind of public requests: from flat to rent to an abandoned building to restore or to drive better investors. The city of Trento will be the pilot project to test these statements.We studied the phenomenon of pushing new constructions rather investing on the reuse of abandoned buildings with the consequences of unsustainable land use. To address the work we adopted a comprehensive approach across the fields of urbanism, ICT engineering and social sciences. We believe that sharing knowledge and know-hows with municipalities, agencies, and citizens is the way to support better market strategies as well as urban transformation policies.

title Cyber(Inter)Sections: Looking into the Real Impact of The Virtual in the Architectural Profession
source Proceedings of the Symposium on Architectural Design Education: Intersecting Perspectives, Identities and Approaches. Minneapolis, MN: College of Architecture & Landscape Architecture, pp. 57-63
summary As both the skepticism and 'hype' surrounding cyberspace vanish under the weight of ever increasing power, demand, and use of information, the architectural discipline must prepare for significant changes. For cyberspace is remorselessly cutting through the dearest structures, rituals, roles, and modes of production in our profession. Yet, this section is not just a detached cut through the existing tissues of the discipline. Rather it is an inter-section, as cyberspace becomes also transformed in the act of piercing. This phenomenon is causing major transformations in at least three areas: 1. Cyberspace is substantially altering the way we produce and communicate architectural information. The arising new working environment suggests highly hybrid and networked conditions that will push the productive and educational landscape of the discipline towards increasing levels of fluidity, exchanges, diversity and change. 2. It has been argued that cyberspace-based human and human-data interactions present us with the opportunity to foster a more free marketplace of ideologies, cultures, preferences, values, and choices. Whether or not the in-progress cyberincisions have the potential to go deep enough to cure the many illnesses afflicting the body of our discipline need to be considered seriously. 3. Cyberspace is a new place or environment wherein new kinds of human activities demand unprecedented types of architectural services. Rather than being a passing fashion, these new architectural requirements are destined to grow exponentially. We need to consider the new modes of practice being created by cyberspace and the education required to prepare for them. This paper looks at these three intersecting territories showing that it is academia and not practice that is leading the profession in the incorporation of virtuality into architecture. Rafael Moneo's words come to mind. [2]

summary This article presents the work the Knowledge Base Group is achieving towards the integration of Artificial Intelligence based facilities in the Building design process. After an overview of the current state of the integrated design process, the context and the technical guidelines to realize computer integrated software in the building design field is described. Then some tools are presented to model the knowledge (the HBDS method) and to implement such model in our Mips home-made knowledge modeling software platform (including object-oriented database management facilities, expert system reasoning facilities, hypertext edition facilities, 3D-design and 3D-view modules...). Finally the authors describe the Quakes application devoted to assess detached house anti-seismic capabilities during the design process. A deep conceptual model considers all the semantic entities (columns, resistant panels, openings, ...) involved in the anti-seismic expertise. Using both this conceptual model description of a detached house and the 3D design tool, they input the project. Then the seismic expertise is driven in a divide and conquer approach and records the alleged configuration recognized automatically linked to the corresponding section of the building regulation

summary The introduction of new technologies in architectural projects causes, in first place, their adaptation as an operative and instrumental resource, without considering the deep changes that their use generates. The digital image, understood as a reference of this process, is spreading and conquering new fields on ideation, representation and communication. The absence of theoretical support, that would offered another point of view is evident, so consequently we believe that is necessary to consider approaches qualitatively new, from epistemologic, methodologic, perceptive and aesthetic fields, in order to transfer them into professional an teaching practice. Today, the annulment of universal validity rules, and the different and contradictory interpretations, oblige to center our view in the interrelationships and,connections, rather than in the definition of each entity. This work develops synthetically a study which confronts and compares traditional project process - composition and heuristic design supported by linear proceeding and analogic media, with confluent project process, based on digital data and hypermedia links, generated simultaneously. The variants of the topics analyzed are at the same time the project itself, the underlying thinking model, and the project communication strategies.

title On Deep Disjunctive Cutting Planes for Set Partitioning : A Computationally Oriented Research.
source Pittsburgh: Design Research Center, CMU [DRC-70-11-82], 10 p.
summary Several mathematical programming problems can be formulated as Disjunctive Programming Problems. This approach offers a powerful procedure for the generation of new and strong cutting planes with desirable properties. For general integer programs, the traditional cutting plane methodologies proved less efficient than enumerative techniques. However, for certain classes of problems, such as set partitioning, cutting planes are known to be efficient. Since the disjunctive cuts are strong, they can be expected to perform better. This paper reports on computational results with disjunctive B(.) cuts for the set partitioning problem, evaluated in terms of computer resources and other independent measures in solving specific randomly generated test problems under controlled conditions.

summary Sky view factor (SVF) is the ratio of radiation received by a planar surface from the sky to that received from the entire hemispheric radiating environment, in the past 20 years, it was more applied to urban-climatic areas such as urban air temperature analysis. With the urbanization and the development of cities, SVF has been paid more and more attention on as the important parameter in urban construction and city planning area because of increasing building coverage ratio to promote urban forms and help creating a more comfortable and sustainable urban residential building environment to citizens. Therefore, efficient, low cost, high precision, easy to operate, rapid building-wide SVF estimation method is necessary. In the field of image processing, semantic segmentation based on deep learning have attracted considerable research attention. This study presents a new method to estimate the SVF of residential environment by constructing a deep learning network for segmenting the sky areas from 360-degree camera images. As the result of this research, an easy-to-operate estimation system for SVF based on high efficiency sky label mask images database was developed.
