title	Computational Derivation of Incident Irradiance on Building Facades based on Measured Global Horizontal Irradiance Data
source	Vienna University of Technology; Building Science & Technology
summary	Reliable simulation of buildings' energy performance requires, amongst other things, the availability of detailed information on the magnitudes of incident solar radiation on building facades. However, the availability of the measured data concerning the incident solar radiation on vertical surfaces is restricted to only few locations. In addition, concurrent measurements of horizontal global and horizontal diffuse (or direct normal) irradiance data are likewise available only for a limited number of locations. In contrast, global horizontal irradiance data is available for many locations. This research demonstrates how to computationally derive incident irradiance values on vertical (or otherwise inclined) building surfaces from measured globalirradiance values. Given this context, three methods are considered to compute incident vertical irradiance values based on measured global horizontal irradiance data. Vertical solar irradiance measurements are described. Then, the computationally derived values are compared withcorresponding measurements. The results are evaluated based on their correlation coefficients and relative error. Finally, the application of horizontal-to- vertical irradiance mapping is demonstrated using the case of an office building at Vienna University of Technology.

title	Computational Assessment of Passive Cooling Methods in Buildings
source	Vienna University of Technology; Building Science & Technology
summary	Various factors have been contributing to a recent steady increase in buildings’ demands for cooling energy: environmental changes, increased heat gains due to equipment and growing expectations in view of acceptable indoor thermal conditions. Given this context, it’s both environmentally and economically meaningful to develop and implement passive cooling techniques toward the reduction of buildings’ demand for cooling energy. In the present study, we use parametric simulations to compute the relative impact of various passive cooling technologies toward the reduction of overheating risk in residential buildings. The cooling measures under examination are shading, natural ventilation (emphasizing on night time natural ventilation), and the application of phase change materials (PCM). The buildings that are being used for the parametric studies are an apartment and a double-storey single house, both simulated for a Mediterranean climate (Athens, Greece) and middle-European one (Vienna, Austria). The results showed that passive cooling methods can significantly contribute the reduction of overheating in buildings. In particular shading and night time ventilation have been shown to be very effective especially if applied in combination. PCMs on the other hand, showed a limited potential in the reduction of overheating risk, at least under the specific climatic circumstances.

title	User Control Actions in Buildings: A Case Study of Shading
source	Vienna University of Technology; Building Science & Technology
summary	This thesis describes the results of a research to find out how users interact with shading and lighting devices in an office building in Vienna, Austria. The aim of the research is to explore the parameters that lead occupants to change shade positions. For this purpose, changes in shading on the southwest and north façades of the building were observed by capturing images of the whole façade. Weather conditions were registered by the weather station mounted on the top of the building. Inside the building, 15 rooms on the southwest façade and 14 rooms on the north façade were selected. Users’ operation of lighting was captured in each room. Data over a period of twelve months was collected and analyzed. The relationship between users’ behavior and environmental parameters was studied. The potential for energy saving through the use of occupancy sensors was explored.

title	Energy conscious automated design of building façades using genetic algorithms

summary	Various European Directives have been issued concerning the energy efficiency of the buildings. The target is the achievement of a near optimum energy efficient environment while at the same time satisfying occupant needs throughout the year within an integrated “holistic” or “whole building” framework. A variety of different antagonistic parameters should be balanced such as window size and glazing transmittance or daylighting and shading and in most cases this requires an examination of various scenarios. Thus the design of building envelopes should address a careful balance between internal requirements and loads, the materials and properties of the façade and the external environment. Nowadays, the available tools for façade design-in terms of building’s energy efficiency- are inappropriate for interactive or creative use. In this paper we examine the development of a genetic algorithm which is capable to optimise the opening areas, glazing properties and shading configurations –on the basis of minimum energy consumption- and then to design automatically simplistic alternative scenarios of the building façade.

title	Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title	Preliminary tectonic phenomena of diversified architectural spatial forms in digital age
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 599-608

summary	The research on tectonics in the architectural field began from the middle of nineteenth century and in recent twenty years digital technology gradually developed and permeated through the field of architecture. Liu and Lim (2006, 2009) integrated classic and digital tectonic factors a present framework of new tectonics. However, the previous studies related to the tectonics in this digital age were only on architectural cases that use a great deal of digital media. The research wants to know what and how the tectonic factors affect the different spatial forms of modern architecture and focused on a case study of the diversified spatial forms, orthogonal, folding and curving. The results show the classic tectonic thinking is imperative until now. It is critical to prove the significance of adding the new digital tectonic factors in digital age.

title	Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 232-250
doi	https://doi.org/10.52842/conf.acadia.2006.232
summary	The paper describes a novel approach involving interoperability, data modeling technology, and application of the building information model (BIM) focused on sustainable architecture. They share relationships and multiple experiences that have existed for years but have never have been proven. This interoperability of building performance simulation maps building information and parametric models with energy simulation models, establishing a seamless link between Computer Aided Design (CAD) and energy performance simulation software. During the last four decades, building designers have utilized information and communication technologies to create environmental representations to communicate spatial concepts or designs and to enhance spaces. Most architectural firms still rely on hand labor, drafted drawings, construction documents, specifications, schedules and work plans in traditional means. 3D modeling has been used primarily as a rendering tool, not as the actual representation of the project.With this innovative digitally exchange technology, architects and building designers can visually analyze dynamic building energy performance in response to changes of climate and building parameters. This software interoperability provides full data exchange bidirectional capabilities, which significantly reduces time and effort in energy simulation and data regeneration. Data mapping and exchange are key requirements for building more powerful energy simulations. An effective data model is the bidirectional nucleus of a well-designed relational database, critical in making good choices in selecting design parameters and in gaining and expanding a comprehensive understanding of existing data flows throughout the simulation process, making data systems for simulation more powerful, which has never been done before. Despite the variety of energy simulation applications in the lifecycle of building design and construction projects, there is a need for a system of data integration to allow seamless sharing and bidirectional reuse of data.

summary	Sustainable development issues are currently the driving forces in many building projects. The building envelope is critical for the architectural expression as well as large parts of the environmental performance. This study tries to investigate the advantages of multidimensional computer aided modeling and simulation for a sustainable facade design approach. A first step towards nD modeling for sustainable design is to establish a list of parameter which are used as design criteria: Environmental performance, thermal visual and acoustic comfort. Computer simulation and analysis of different building elements can help to determine the performance according to a set of design parameter. Environmental impacts due to energy consumption are an important parameter but it is believed that comfort criteria need also to be accounted for.

title	An Analysis of the Applications of Rapid Prototyping in Architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	Diretrizez Geométricas de Auxílio ao Processo de Projeto de Edifícios Residenciais [Geometrical Guidelines to Aid the Design of Floor Plants of Residential Buildings]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 243-247
summary	This paper discusses the basic principles of a geometric method to aid the design process of residential buildings. It makes part of the initial phases of a research whose aim is to develop a computer system to aid the sketching and evaluation of floor plant design of multi-storied residential buildings. The fundamental idea of the research is the existence of some basic patterns of floor plants that reflect the designer’s mental models in this category of building. The models are regarding the usage of the space such as forms and dimensions, the elements for the circulation and the external skins. During the design process, architects work on each one of these models to generate the sketches of the floor plant layout. Generally, the layout of an apartment in multi-storied buildings depends basically on the internal dynamics of the users without the complex relationship with the neighborhood environment as in the case of houses. In this way, it would be easier to identify, to organize and to associate the mental models of multi-storied buildings on geometric basis, which, in their turns, might be effectively used as inputs for the layout planning of new design. By applying the geometric basis, the architects may reduce the universe of feasible alternatives into a small group of heuristic solutions that can be described by using few simple guidelines. In addition to this, the geometric bases of the existing buildings might be used to build a knowledge-based system to aid the architectural design. The objective of this paper is to show some initial results of the research obtained from a survey and the case studies of form, dimensions and topology of existing buildings. To limit the scope of the discussion, only residential buildings with two to three bedrooms are considered. At first, a survey of plants of residential buildings with two and three bedrooms, in Brazil, is carried out. In the next step, the dimensions, shape, external skin perimeter, circulation system and accessibility are analyzed. Finally, typical topologies of the building are investigated.

summary	The theme of this conference builds on and investigates the pre-existing and endlessly unfolding relationship between two domains of scientific inquiry: Architecture, urban design and planning, environmental design, geography and Social theory, media and communication studies, political science, cultural studies and social anthropology. Architectural design involves communication and could thus be partly considered a communicational activity. Designers (or not) see architectural designs, implicitly, as carriers of information and symbolic content; similarly buildings and urban environments have been “read” and interpreted by many (usu- ally not architects) as cultural texts. At the same time, social and cultural studies have studied buildings and cities, as contexts for social and cultural activities and life in general, from their mundane expression of “everyday life” (Highmore, 2001) to elite expressions of artistic creativity and performance. Information and communication technologies (ICTs) support both of these levels of scientific inquiry in many ways. Most importantly however, ICTs need design studies, architectural and visual design, social and cultural studies in their quest to create aesthetically pleasing, ergonomically efficient and functional ICT sys- tems; this need for interdisciplinarity is best articulated by the low quality of most on-line content and applica- tions published on the web.

summary	Urban space provides a context for human interaction. Recently, urban planning has largely placed the user at the street as the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. However, visual observation is often difficult for verifying planning goals. The simulation of pedestrian behaviour is important for physical planning, but such research is scarce. In this study, we adopt an empirical approach for generating reactive path following. Further, we implement scenarios as computer scripts with agent-based interfaces to identify navigational patterns. Moreover, we built a hierarchy of individual behavioral models and define a behavior production system to control the agent. Key attributes of streets such as rest space, utilities, landmarks, and buildings have space tags as identifiers to associate streets with related activities.

title	An Intuitive Interface for Building Management and Planning
source	International Journal of Architectural Computing vol. 4 - no. 2, 17-26
summary	Building management and planning professionals utilize database systems for administrative support, but these systems are inadequate for conveying architectural plans. In this article we describe the so-called Virtual Maquette that was developed at the Eindhoven University of Technology for the board of the University. The Virtual Maquette consists of a vertical display for 3D view and information of building stock, and an interactive horizontal display for manipulation of view and information. Interaction is implemented using infrared tracking of devices that are positioned on the desktop with the projected plan view. Through this interface the states of the buildings can be inspected at different periods in history and in the future. The support of multiple devices in a single environment is a technical challenge, but it provides a new interaction method for non-technical persons.

source	Proceedings of the GAME, SET, MATCH II, conference at the Technical University of Delft, Netherlands, 29 March - 1 April 2006, pp. 494-501
summary	In the September 1969 issue of Architectural Design, Andrew Rabeneck wrote about the use of cybernetic devices within an automated architecture. He hypothesized that the concept of ‘flexibility’ was introduced to architecture because existing building technologies were inherently inflexible. He argued that architects should use cybernetic technologies to produce completely new types of increasingly flexible, user-centred, buildings. Three years later, Yona Friedman wrote about the changing relationship between clients and architects. He said that a new design methodology was needed because architects could not assess the future spatial needs of building users accurately enough. Proposing a new model, he split architectural design in two complementary halves, hardware design and software design, reasoning that this would give users the opportunity to adapt built spaces to suit their needs. Both of these ideas describe approaches to the production of an architecture that can change shape and configuration in response to changing patterns of use. Rabeneck’s approach illustrates the benefit of predictive technologies and automation, while Friedman’s model illustrates the benefit of user intervention and direct manipulation. This paper discusses developments in the field of responsive architecture in relation to two opposing user-centred interaction methodologies. It proposes methods for controlling responsive buildings and suggests that human computer interaction methodologies need to be re-thought and extended when applied within intelligent, responsive, architectures.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	Forms of Participation in Urban Redevelopment Projects - The differing roles of public and stakeholder contributions to design decision making processes
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 375-390
summary	This paper examines how political commitment to participatory design within the context of a major urban redevelopment project was translated into a strategy and a course of action for achieving effective participation within a demanding project timeframe. The project in question involves a new transport interchange for the city of Auckland (New Zealand), the redevelopment of a number of heritage buildings, and the introduction of new buildings to create a mixed use precinct covering three city blocks. The project, currently being implemented, has involved extensive public consultation and stakeholder participation as it has proceeded through the stages of project visioning, an open public design competition, and the development of the competition winning design. The paper draws a distinction between the contributions of stakeholders versus the public at large to the decision-making process, outlines the different kinds of participatory processes adopted by the local authority (Auckland City Council) to effectively engage and involve these two different groups and the stages in the evolution of the project at which these different contributions were introduced. The model of 'open design' proposed by van Gunsteren and van Loon is used as a basis for explaining the success of multi-stakeholder inputs at a crucial stage in project development. The paper concludes by examining the limits of applicability of the 'open design' model in the context of urban redevelopment projects in which there is broad public interest, and by suggesting a number of design decision support guidelines for the management of participatory processes.

summary	Various approaches of virtual and physical modeling have led to a synthetic form of making that is plastic and scalable in nature. This shift from traditional forms of representing and generating architecture now offers a better possibility of full-scale construction and fabrication processes and links transparently to industry. Architects are beginning to dynamically inform the visioning processes of assemblies and design through a range of precise subassemblies. Further to this end, the synthetic techniques and materials are opening up avenues for designers to investigate a range of fibers and fabrics that radically transform light and color renditions, and texture. Investigations in the realm of traditional materials such as stone, wood, and concrete continue to evolve, as do their associated methods of making. As a result of synthetic technologies, architects today have the possibility to work along side industry engineers and professionals to design castings, moldings, patterns, and tools that challenge not only the architectural work of art, but industrial and product design as well. This cultural shift from physical space to virtual space back to physical space and the combination of hand-, digital-, and robotic-making offers a unique juxtaposition of the built artifact to its manufacturing that challenges both spatial conventions and also the levels of precision and tolerance by which buildings are assembled. Traditional forms of documentation for example result typically in discrepancies between the drawn and the actualized which are now challenged by the level of precision and tolerance at the virtual level. It is within this context that leading-edge architects and designers operate today. Yet, how the profession and the academy respond to these opportunities remains an open line of inquiry and addressing these concerns opens up the rich potential enabled through synthetic making.

title	Optimal Distribution of Architecture Programs with Multiple-constraint Genetic Algorithm

summary	A genetic algorithm (GA) is a search technique for optimizing or solving a problem based on evolutionary biology, using terms and processes such as genomes, chromosomes, cross-over, mutation, or selection. The evolution starts from a population of completely random individuals and happens in generations. In each generation, the fitness of the whole population is evaluated, multiple individuals are stochastically selected from the current population (based on their fitness), modified (mutated or recombined) to form a new population, which becomes current in the next iteration of the algorithm. In architecture, GAs are of special interest mainly because of their ability to address a problem offering a multiplicity of possible solutions. Contrary to other algorithms where the objective is to accommodate a manually conceived diagram, GAs are emergent procedures that evolve over time through multiple attempt cycles (i.e. generations) and therefore offer a bottom-up approach to design. In addition, by using the computational power of computers they can resolve complex interactions between multiple factors and under multiple constraints offering solutions that occasionally surprise the designer. One of the main problems in architecture today is the quantity of the information and the level of complexity involved in most building projects. As globalization and economic development has started to arise at unprecedented levels, the need for large urban developments have become commonplace. Housing projects for a few hundreds to thousands of people have started to emerge over large urban areas. In such cases, the old paradigm for housing design was the development of high rises that served as stacking devices for multiple family housing units. Such a direction was unfortunately the only way to address excessive complexity using manual design skills mainly because it was simple to conceive but also simple to construct. The unfortunate nature of this approach lies rather in the uniformity, similarity, and invariability that these projects express in comparison to individuality, discreteness, and identity that human beings and families manifest. One of the main areas of complexity that could benefit architecture is in housing projects. In these projects there is a typology of residential units that need to be combined in various schemes that will fulfill multiple functional, environmental, and economic constraints. In this paper, the design of a 200-unit residential complex on a corner of two streets in an urban context was investigated as a case study. Recent advancement in tectonics and structural engineering enables the realization of buildings in mega scales and starts to introduce another layer of complexity into the building programs. Conventional design methods relying on the preconceived knowledge based approaches are no longer reliable. Beyond the certain quantitative factors and the complexity of the problems, search occasionally enters into the unpredictable domain of the human perception. Computational approaches to design allows us to go through thousands of iterations in a second and find the solution sets beyond the reach of designers’ intuitive search spaces. Genetic Algorithm can be a potential derivative for finding optimum design solution from indeterminate search spaces constrained by multi dimensional factors.
