summary	We present a simulation platform to evaluate procedurally generated 3d city models with a set of agents representing urban street actors and pedestrians towards greenhouse gas emissions from transportation. Our aim is to give architects and urban planners an empiric tool to analyze, predict and quantify traffic fluctuations over time, and define the number of occupants, individual traffic and public transport in a city. In this project we show that the allocation of functions within a city is an important factor for the appearanceof traffic. The occupant’s decisions where they want to go are defined by the allocation of functions – and the distance defines the mode of transportation. We simulate the decision processes and gain information about the path, the mode of transportation, and the emissions they produce, and individual experiences like stress and effort. The autonomous driving cars are equipped with an acceleration based emission model allowing us to evaluate the inpact of jammed streets on the emission of cars.

title	Energy Performance Modeling of an Office Building and Its Evaluation – Post-Occupancy Evaluation and Energy Efficiency of the Building

summary	Energy performance modelling can provide insights into the efficiency and sustainability of commercial buildings, and also the achievement of certification standards such as USGBC LEED. However, the results from the modelling must be validated via a post-construction evaluation, which quantifies any discrepancies between the predicted energy usage and the actual energy consumed. In this study, an existing office building was examined to test how well the model predicts energy usage. The results from the model were compared with the actual usage of gas and electricity over two years (2010-2011). Our study showed a 123% higher gas usage,and a 36% lower electricity, compared with the simulation. This difference presents that occupant behaviour and building construction practices have significant impact on the energy usage of a building. For instance, the large discrepancy among gas usage is due to the office building’s thermal envelope, which identifies the spots at which heat leaks out of the building, thereby forcing the heating unit to work more. Additionally, the post occupancy evaluation study identified that indoor environmental conditions impact on energy consumption of the building.

title	Luz natural: avaliação dinâmica e interativa nos ambientes arquitetônicos virtuais [Natural light: assessment in dynamic and interactive virtual architectural environments]
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 260-263
summary	Real time walkthrough is a valuable resource, especially in the early stages of the design process. Assessing how shadows and reflections behave enables architects to make better choices regarding materials, geometry and lighting. Traditional methods do not offer daylight simulations in real time, whereas interactive visualization requires large computational resources to allow an evaluation of behavior of light in architectural space. This project researched virtual environments that permit the real - time generation of interactive scenes that simulate natural light algorithms modeled. The goal of this is to meet the needs of architects when evaluating the changes of a dynamic and synchronous project.

summary	The scope of this paper is the identification of elements in architectural space that can trigger human behavior in both real and virtual environments. These elements can be either material, such as shapes and volumes or immaterial, such as light and shadow. Our research depends on a series of experiments taking place in an existing architectural environment (a high-school) and its virtual counterpart, focusing mainly on the spatial perception and cognition by the subjects through real-time navigational means. The aspect that survey knowledge (spatio-exploratory or exocentric perception) is “primary” in virtual environments seems to be confirmed. It is indicative that in the virtual environment the movement of subjects (primarily visitors) is related and defined strongly by specific architectural elements, such as a stoa and the staircases, while being strongly exploratory.

doi	https://doi.org/10.52842/conf.acadia.2010.258
summary	This paper presents recent research for new mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on insect and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The proposed façade system uses integrated sensors and actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to manufacturing methods and material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli, and ultimately, effective performance of the whole system.

summary	This paper demonstrates an ongoing research investigation, which is the continuation of the author’s doctoral research on a computer-based design approach that is used for the generation of circulation diagrams, and the spatial organization of functional areas in macro-scale design level. The paper introduces a computer program that is based on the idea of particle behavior modeling. The program simulates the human movement behavior in real time and in parallel, based on simple rules of interaction between particles. The model is called a ‘virtual force’ model, since the interaction between particles, and hence human movement behavior modeling, is achieved by using various forces that are acting upon each particle. Any changes on the rules of interaction can produce different results, allowing architects to investigate various design possibilities and study the human movement behavior in different design case studies. In this paper the idea of modeling such movement behavior is investigated and developed further, in order for it to be used for the design of circulation systems, and to suggest solutions to problems that occur in public areas of cities.

title	Material Information: Integrating Material Characteristics and Behavior in Computational Design for Performative Wood Construction

summary	Architecture as a material practice is still predominantly based on design approaches that are characterized by a hierarchical relationship that prioritizes the generation of geometric information for the description of architectural systems and elements over material specific information. Thus, in the early design stage, the material’s innate characteristics and inherent capacities remain largely unconsidered. This is particularly evident in the way wood constructions are designed today. In comparison to most construction materials that are industrially produced and thus relatively homogeneous and isotropic, wood is profoundly different in that it is a naturally grown biological tissue with a highly differentiated material makeup . This paper will present research investigating how the transition from currently predominant modes of representational Computer Aided Design to algorithmic Computational Design allows for a significant change in employing wood’s complex anisotropic behaviour, resulting from its differentiated anatomical structure. In computational design, the relation between procedural formation, driving information, and ensuing form, enables the systematic integration of material information. This materially informed computational design processes will be explained through two research projects and the resultant prototype structures. The first project shows how an information feedback between material properties, system behaviour, the generative computational process, and robotic manufacturing allows for unfolding material-specific gestalt and tapping into the performative potential of wood. The second project focuses on embedding the unique material information and anatomical features of individual wooden elements in a continuous scanning, computational design and digital fabrication process, and thus introduces novel ways of integrating the biological variability and natural irregularities of wood in architectural design.

title	Understanding Behavior of Self - Organizing Vehicle Sharing Systems
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 392-395
summary	Mobility on Demand (MoD) is a self - organizing one - way vehicle sharing system that allows users to pick - up from and drop - off to at station. MoD uses sensors to understand fleet distribution asymmetry and price incentives to motivate users to drive vehicles to stations that need the them most thereby increasing service performance. This paper presents current work done at the Smart Cities group of the MIT Media Lab for understanding decision - making in dynamically priced vehicle sharing systems, and exploring the circumstances under which such systems can become stable, sustainable, and profitable.

title	Situated Bioclimatic Information Design: a new approach to the processing and visualization of climate data
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 88-96
doi	https://doi.org/10.52842/conf.acadia.2010.088
summary	Currently, most approaches to graphic evaluative frameworks (GEFs) for the early-stage evaluation of bioclimatic design strategies adopt a design-tool metaphor, wherein a battery of analytical routines is performed by a software tool based upon a standardized weather file from which a stock set of graphic material is produced. In seeking to evaluate a broad range of climates and to address a wide variety of passive design strategies, existing climate visualization and evaluation tools position themselves far outside of the context of a situated design problem. Remaining agnostic to the particularities of site, program, tectonic system, and material behavior these tools become, by definition, generic. As a consequence, while such design-tools can be effective in evaluating particular relationships between environmental resource, demand profile, and built-system, they maintain a potential to be rendered ineffective in any outlying cases not specifically anticipated by their authors . Situated Bioclimatic Information Design (SBID) presents an alternative approach that targets a class of design strategies prominent among these outlying cases: those highly responsive to negotiation between the continually fluctuating resources within microclimates and the fluctuating demand profile of the building program. Using a custom-built weather data parser a number of diagrams and data visualizations have been produced under this approach. These visualizations are not only useful in and of themselves for aligning design strategies to specific contexts, but they also illustrate the foundations of a larger theoretical framework for the processing and visualization of climatic data for effective utilization of bioclimatic flows.

summary	In the current design practice, new digital tools have emerged -visual- also called Infrastructures (Perkel, 2011) such as; Behance 2003, Pinterest 2009, Archdaily 2008, Instagram (2010) -to cite the most recognized in the creative field in Argentina-, which promote different opportunities and support the creative process and problem solving, making it easier for designers to find inspiring material through the Internet. However, very little is known about how these new practices affect professional work, how they themselves see it and the tensions they generate.This article will present the results of a general survey applied to expert designers as part of the first stage of the Doctoral Research project. Which investigates the behavior referred specifically to the use of visual platforms -visual social media- in order to understand, characterize, describe the use and involvement of them within the design process.

summary	The finding of a functional program for any kind of building involves a great amount of knowledge about the behavior of future building users. This knowledge can be gathered by looking at relevant building literature (Adler, 1999; Neufert and Neufert, 2000) or by investigating the actual processes taking place in similar environments, the latter being demonstrated e.g. by (Schütte-Lihotzky, 2004) or new functionalist approaches of the MVRDV group (Costanzo, 2006)). Both techniques have the disadvantage that the architect might assume a behavior which is seldom experienced in real life (either through lack of information or by failing to meet the building user’s expectations). What is needed is a verification step in which the design is tested on real users. We have devised a game-like environment (Figure 1a) in which it is possible to capture the behavior of future building users in order to verify the relevance of the design even at a very early stage. As result of applying our approach, we can find previously overlooked usage situations, which may be used to further adapt the design to the user’s needs.

title	Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary	In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

title	Embedded Rationality: A Unified Simulation Framework for Interactive Form Finding
source	International Journal of Architectural Computing vol. 8 - no. 4, p. 39
summary	This paper describes embedded rationality as a method for implicitly combining fabrication constraints into an interactive framework for conceptual design. While the concept of ‘embedded rationality’ has been previously discussed in the context of a parametric design environment, we employ this concept to present a novel framework for dynamic simulation as a method for interactive form-finding. By identifying categories of computational characteristics, we present a unified physics-solver that generalizes existing simulations through a constraint-based approach. Through several examples we explore conceptual approaches to a fixed form where the resulting effects of interacting forces are produced in real-time. Finally, we provide an example of embedded rationality by examining a constraint-based model of fabrication rationale for a Planar Offset Quad (POQ) panelization system.

summary	The following paper deals with a performance-driven morphogenetic design task to improve the conditions of room acoustics, using as a case study the material laboratory of the School of Architecture at Federico Santa Maria University of Technology. Combining contemporary Parametric Modeling techniques and a Performance- Based approach, an automatic generative system was produced. This system generated a modular acoustic ceiling based on Helmholtz Resonators. To satisfy sound absorption requirements, acoustic knowledge was embedded within the system. It iterates through a series of design sub-tasks from Acoustic Simulation to Digital Fabrication, searching for a suitable design solution. The internal algorithmic complexity of the design process has been explored through this case study. Although it is focused on an acoustic component, the proposed design methodology can influence other experiences in Parametric Design.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	The state university of Campinas, Unicamp, is a public university in upstate São Paulo, Brazil, ranked the second best in the country. It was founded in 1966, and its main campus started to be built in 1967, in the suburbs of Campinas, nowadays a two-million people city. The area of the campus is almost 3 million square meters (300 hectares), with a total built area of 522.000 m2 and a population of 40 thousand people - 30 thousand students, 2 thousand faculty members and almost 8 thousand staff members. The campus’ gross population density is 133 people per hectare. Less than 6% of the total campus area is presently occupied. The design of Unicamp's campus is based on concepts that were typical of the modern movement, with reminiscences of corbusian urbanism, in which preference is given to cars and buildings are spread apart on the territory, with little concern to the circulation of pedestrians. The standard building type that has been built on campus since the 1970's is based on non-recyclable materials, and has a poor thermal performance. Unicamp is expected to double its number of students by the year 2030. The campus density is thus expected to grow from 600 people per hectare to almost 1,000 people per hectare. The need to construct new buildings is seen as an opportunity to correct certain characteristics of the campus that are now seen as mistakes, according to sustainability principles. This paper describes a set of proposals targeting the increase of the campus' density in a sustainable way. The plan also aims at increasing the quality of life on campus and diminishing its impact on the environment. The main targets are: - Reducing the average temperature by 2oC; - Reducing the average displacement time by 15 minutes; - Increasing the campus' density by 100%; - Reducing the CO2 emissions by 50%. // In order to achieve these goals, the following actions have been proposed: Developing a new standard building for the university, incorporating sustainability issues, such as the use of renewable and/or recyclable materials, the installation of rainwater storage tanks, the use of natural ventilation for cooling, sitting the buildings in such a way to decrease thermal gain, and other issues that are required for sustainable buildings' international certifications. To assess the performance of the new standard building, different simulation software were used, such as CFD for checking ventilation, light simulation software to assess energy consumption, and so on. 1. Filling up under-utilized urban areas in the campus with new buildings, to make better use of unused infrastructure and decrease the distance between buildings. 2. Proposing new bicycle paths in and outside campus, and proposing changes in the existing bicycle path to improve its safety. 3. Developing a landscape design plan that aims at creating shaded pedestrian and bicycle passageways.

summary	Computational fluid dynamics (CFD) is a method of solving and analysing problems that involved fluid flows. In the field of architecture, urban design and urban planning, CFD is useful for the analysis of ventilation and airflow in the built environment, especially in very dense cities. This paper will look into the possibility of making CFD more accessible to the general design and planning field. A simulation is done on a urban design proposal to quickly see how air flow behaves around it. From there, it looks into the future where technology will make CFD simulation more easily adopted and the possibilities of integrating the ventilation analysis with other environmental analysis results into the urban design arena.

summary	This paper aims to discuss alternative and innovative plan models for Chinese cities that are currently under rapid development. Our study considers Complexity Theories of Cities as theoretical base and applies a holistic approach in city planning by recognizing the complex nature of city. We strive to integrate the diverse local structure in social and spatial aspects with the ambition and demands of city’s expansion. Digital sequence simulation is used as an innovative tool to represent local activities, promote interventions and predict possible self-organization process in the future. The study arrives at an open scenario the feasible prospect. A conclusion is drawn to reflect the process, achievement and weakness of the research.
