    ability to adapt to unpredictable changing forces This method can be applied over different structural elements façade elements canopies and structural components etc to achieve adaptation to other parameters with an unpredictable pattern such as human behaviour or weather conditions Top Choreographic Architecture Inscribing instructions in an auxetic based material system Theodoros Themistocleous This paper presents the development of an SLS 3D printed auxetic structure actuated to a predefined form by an embedded pneumatic network through an iterative process of feedback between digital simulation and physical testing This feedback process is critical to the development of a more accurate predictive model and to compose the geometry of the suggested structure An approach based on the emergence of final structure from the convergence of the behavior of sub structures has been introduced from the beginning and a methodology based on the analysis and synthesis of the simplest sub system is the core of this research The results indicate a promising simulation environment and a novel methodology for the design and fabrication of auxetic structures with embedded pneumatic actuation This exploratory research suggests a fertile research space within the field of adaptive architecture and kinetic design Top Façade s Apertures Optimization Integrating Cross Ventilation Performance Analysis In Fluid Dynamics Simulation Chrysanthi Sandy Karagkouni Ava Fatah gen Schieck Martha Tsigkari and Angelos Chronis Performance oriented design has as a primary aim to in troduce spaces that achieve acceptable levels of human comfort Wind induced airflow plays a significant role in the improving occupants comfort in a building This paper explores the extent to which simulation of natural airflow can potentially be a contributing parameter in the concep tion of performance aware designs Testing the natural ventilation performance of a pavil ion the study employs Fast Fluid Dynamics simulation A performance analysis is conducted whereby an array of automated feedback loops carried out by a genetic algorithm can produce a number of acceptable solutions as regards the optimization of facades openings The experimentation conducted proves the ability of the model to yield design instances that fulfill a number of environmental criteria related to airflow and human comfort In this light the paper suggests that the aforementioned method can be used as an experimentation platform to influence the direction a designer may take when considering a design proposal Top A Review Of The Brazilian NBR 15575 Standard Applying The Simulation And Simplified Methods For Evaluating A Social House Thermal Performance Tassia Helena Teixeira Marques and Karin Maria Soares Chvatal The new Brazilian ABNT NBR 15575 Standard recommends two methods for analyzing housing thermal performance a simplified and a computational simulation method The aim of this paper is to evaluate both methods and the coherence between each other For this the thermal performance of a low cost single family house was evaluated through the application of the procedures prescribed by the Standard To accomplish this study the EnergyPlus software was selected Comparative analyses of the house with varying envelope U values and solar absorptance of external walls were performed in order to evaluate the influence of these parameters on the results The results have shown limitations in the current Standard computational simulation method due to different aspects weather files lack of consideration of passive strategies and inconsistency with the simplified method Therefore this research indicates that there are some aspects to be improved in this Standard so it could better represent the real thermal performance of social housing in Brazil Top Thermal Reconstruction of a Crime Scene Using Calibrated Simulation Nathan Brown Susan Ubbelohde George Loisos Santosh Philip and Ibone Santiago This study utilized energy simulation in support of a forensic pathology time of death analysis for a corpse discovered in a single family residence two years prior to the study In order to produce an accurate estimate of the interior temperature profile at the time of death a thermal model was constructed using EnergyPlus and calibrated using environmental monitoring data from the site The thermal model was able to predict the temperature in the room of interest within 1 4 C 2 5 F with 90 confidence This model was then altered to account for known differences between the monitoring period and the period of interest and used to predict what the temperature profile had been at the time of death This study adds to a small body of work that compares simulated to measured performance data for unconditioned spaces which should have a growing relevance as building energy performance simulation BEPS tools are used to model passive strategies Top Modeling Analysis and Simulation of a Form Found Civic Sculpture for Lower Manhattan Zak Kostura Erin Morrow and Ben Urick Analysis and design of an 8 storey cable net sculpture for a new transit center in Lower Manhattan required its designers to adopt a highly integrated computational approach This approach combined aspects of structural analysis form finding 3D and parametric modeling to achieve the artistic objectives of the sculptural form while ensuring desired performance of the extensive tensile system This paper presents an overview of the artistic and functional objectives of the cable net and describes in detail the design approach of the project team including software integration nonlinear analysis geometric modeling documentation and construction administration It outlines a partial approach toward performance based design for a system with strong aesthetic objectives and a collaborative approach to construction administration to manage risk amogst the various stakeholders Top Visualization in 3ds Max for Cell DEVS models based on Building Information Modeling Victor Freire Sixuan Wang and Gabriel Wainer Building Information Modeling BIM increasingly ben efits from modeling simulation and visualization tech niques 3D visualization can provide a better way to obtain visual simulation results in BIM authoring tools In this pa per we focus on improving interoperability traceability re usability and visibility of 3D visualization We employ the DEVS Discrete Event Systems Specification formalism and its cellular extension Cell DEVS providing a method for visualizing Cell DEVS models based on moving entities We used this technique to develop a 3ds Max visualization plug in for Cell DEVS models based on BIM This tool can show different animation models and allows designers to fil ter the building for visibility We also show two case studies applying this tool for evacuation and occupancy simulation Top Evaluating the Performance Robustness of Fixed and Movable Shading Devices Against Diverse Occupant Behaviours William O Brien Given the diverse operating conditions weather conditions space users and occupant preferences of buildings it is commonplace to provide occupants with multiple means to adapt their immediate indoor environment However numerous studies have shown that occupants sub optimally use such controls to improve comfort during times of significant discomfort but are much more passive when the source of discomfort is alleviated Occupant related building performance simulation BPS models continue to use very simple and rigid rules when a building s performance is predicted despite the topic s complexity This is likely an artifact of envelope load dominated buildings whose energy use is mostly dependent on their ability to isolate the indoor environment But as envelopes and HVAC become more efficient occupants are playing an increasingly important role on building performance especially for highly efficient building e g net zero energy buildings Traditionally the associated uncertainty of these effects has been excused for the designer and isolated during design by focusing on energy performance relative to a reference building This paper proposes a method using a combination of probabilistic occupant models and explicit models of adaptive comfort to gain an improved understanding of robust building design Results of an example of yield 45 lighting energy savings if a fixed shading device is present Top Simulating the Sensing of Building Occupancy Simon Breslav Rhys Goldstein Ben Doherty Dan Rumery and Azam Khan Accurate building occupancy information can be beneficial in minimizing energy use by improving the intelligence of a Building Automation System BAS and helping designers predict the effect of different design options on occupant behavior However current occupancy measurements are quite inaccurate due to limitations in sensing technology and the resulting discrepancies between sensor data and what actually happens In this paper we explore the use of simulation to model occupant behavior in combination with motion sensors to be able to study the relationship between known and measured occupant behavior An extensible occupancy model influenced by computational cognitive science and implemented using established modeling conventions is presented along with a simple experiment comparing the effects of different sensor density levels Top Development of Discrete Event System Specification DEVS Building Performance Models for Building Energy Design H Burak Gunay William O Brien Rhys Goldstein Simon Breslav and Azam Khan The discrete event system specification DEVS is a formalism for describing simulation models in a modular fashion In this study it is exploited by forming submodels that allow different professions involved in the building design process to work independently to create an integrated model These submodels are the building the HVAC system and the occupant In this study a coupled DEVS building energy model of a generic office space is presented to demonstrate the viability of the DEVS formalism for BPS based design Results indicate that the DEVS formalism is a promising way to improve poor interoperability between models of different domains involved in building performance simulations Top City Information Modeling CIM and Urbanism Blocks connections Territories People and Situations Todor Stojanovski The urban theory is voluminous body of knowledge There is a kaleidoscope of urban definitions and standpoints but there are no tools that capture the variegated viewpoints and representations in urbanism In this article I look at different urban theories discourses and representations in architecture sociology geography economy transportation computer science in order to conceptualize city information modeling CIM CIM is conceived and discussed as a system of blocks with dynamic relations or connections that define and redefine territories The urban life today is a sequence of temporally inhabited and interconnected spaces movable or fixed The connections between spaces inspire or inhibit contacts and interactions between people They bend times and continuously shape and reshape spaces sociabilities and situations In architecture there was an evolution from computer aided design CAD to building information modeling BIM but in urbanism where the geographic information systems GIS dominate there is no such analogy Top A Study of the Relationship between Urban Form and Environmental Performance for Three Urban Block Typologies of Paris Ji Zhang This study explores the relationship between urban form and environmental performance by analyzing three representative urban street block typologies proposed for Paris through her urban history The performances of these typologies in terms of daylight potential annual insolation exposure to the sky and potential to produce urban heat islands were simulated and compared The implications of the results in 1 the importance of appropriate performance indicators to be used in comparative studies and 2 the relationship between urban form density and environmental performance were discussed Top End node Approach for Pedestrian Flow Simulation Hiroshi Ota Studies on urban networks mostly focus on street systems such as streets as links and junctions as nodes This paper proposes the evaluation model with building nodes to examine how buildings may contribute to the whole urban network Firstly by evaluating the total floor area of building nodes in the calculation process of betweenness centrality the paper proposes the potential pedestrian flow which has acceptable correlation coefficient with the pedestrian flow in the actual street network Secondly the paper explores the approach to regard urban network as a queueing network where end node congestion controls are possible For the general understanding of the methodology the simulation in this paper principally focuses on the effect of changes in building clusters which elements are all defined as end nodes and the advantage of the change in decentralized clusters was confirmed Top Designing In Performance Cloud based Simulation and Multidisciplinary Design Solution Space Search Shih Hsin Eve Lin and David Gerber This research is built upon a previously established multidisciplinary design optimization MDO framework and further explores the impact of this framework on the early stages of design Specifically this paper addresses the potential of introducing a cloud based approach to tackle geometrically complex design problems and to facilitate early stage design exploration To address these interests two experiment sets are presented and then discussed in the context of the application of cloud based computing First is a hypothetical scenario possessing complex geometry to understand how the existing established framework assists in the exploration of complex geometric design problems Second is a pedagogical benchmark case allowing for the observation of the human versus automated decision making process By comparing these processes the impact of the established MDO approach on designing in performance and the potential impact of applying cloud based computing to the MDO framework can be revealed and discussed Top From Statistical to Diagrammatic Geo Spatial Time Based Data Visualization Through Parametric Modeling Ming Tang Chris Auffery and Mingming Lu The paper describes experiential learning outcomes in the application of geospatial data to generate diagrammatic representations It also focuses on models and animations used in engineering architecture and urban planning to visualize specific urban issues such as urban health education crime and air pollution as they are currently being confronted in major cities such as Cincinnati The paper discusses how to reconstruct geospatial and time based data into various representations It describes the process of visualizing and representing databases with emerging parametric modeling and animation tools Starting with statistical data parametric design tools are used to decode and recode the social cultural economic and environmental complexity within the parametric equation Computational tools for architects and urban designers such as Geographic Information Systems GIS Excel Maya Rhino and Grasshopper plugin are used to build platforms that allow parametric control of the rendered outcome Top Integrated Design in the Simulation Process Martha Tsigkari Angelos Chronis Sam Conrad Joyce Adam Davis Shuai Feng and Francis Aish During the past decade the construction industry has been witnessing a constant shift in the way it operates The advances of technology have made possible the adaptation of a more direct performance driven design approach based on multi objective and sometimes contradicting criteria of environmental structural economic and aesthetic impact As a consequence the various teams of consultants involved in the process no longer inform it consecutively forcing various changes at different stages of the design Instead building projects increasingly comprise numerous design issues that can be delegated to small groupings of architects engineers and consultants to be resolved simultaneously in parallel In the light of this new status quo the significance of new customized simulation tools and interfaces capable of providing near real time feedback and driven by multiple input criteria looms as a potential game changer to the industry This paper outlines the advances implemented by the authors to support these new integrated workflows Top Building Simulation Weather Forecast Files for Model Based Predictive Control José A Candanedo Éric Paradis and Meli Stylianou Model Based Predictive Control MPC has received significant attention in recent years as a tool for load management in buildings MPC is based on predicting the response of a system based on knowledge of future inputs such as weather and occupancy Despite the availability of online weather forecasts there is a lack of software tools enabling the use of weather forecast information in building modelling This paper describes a proof of concept approach to the creation of EnergyPlus Weather EPW files containing weather forecast information These EPW files updated at periodic intervals also contain up to date recorded measurements thus permitting to establish initial conditions by applying warm up simulations The combination of recorded data and expected weather allows the use of these files in predictive control This approach can be readily reproduced for different weather file formats and other locations Top How Hot Can the University Campus Get in 2050 Environmental Simulation of Climate Change Scenarios at an Urban Neighbourhood Scale Chengzhi Peng and Amr Elwan Based on the results from simulating a case study neighborhood design to be built in New Cairo Egypt a conceptual framework and an environmental simulation work flow towards Climate Change Conscious Urban Neighborhood Design C3UND is proposed Coupling neighborhood outdoor and building indoor simulations the C3UND work flow is further applied to a neighborhood site at the Sheffield University campus in England with weather data representing 2010s and 2050s We describe how the ENVI met platform can be applied to contextualize Ecotect building simulations taking into account the present day as well as future simulated urban micro climatic conditions This study suggests that environmental simulation of climate change scenarios at an urban neighborhood scale is currently achievable but not without considerable gaps The lessons learned and areas for further research are discussed Top Improving Building Performance at Urban Scale with a Framework for Real time Data Sharing Xiufeng Pang Tianzhen Hong and Mary Ann Piette This paper describes work in progress toward an urban scale system aiming to reduce energy use in neighboring buildings by providing three components a database for accessing past and present weather data from high quality weather stations a network for communicating energy saving strategies between building owners and a set of modeling tools for real time building energy simulation Top Isomorphic City A Customizable Future Scenario Susannah Dickinson David Gonzalez and Kyle Szostek This paper discusses a future city design and research project for Tucson Arizona USA The project Isomorphic City set in the year 2087 develops a truly customizable and ever adapting computational approach to the existing built environment Part of the challenge was to design digital methodologies that could simulate this scenario in as live a way as possible incorporating real time live data into the equation ranging from environmental criteria to social media information Form was the result of inputted parameters verses the making of form in a traditional object like fashion The project anticipates a shift of simulating the urban condition with a rule based set of criteria to
