    material active components Here we are due to restraints on computational level as due to the nature of a necessarily open ended design process not able to simulate the structure in a high resolution The Dermoid projects proposes a multi scalar approach which is based on the calibration of the FE simulation with the help of physical prototypes The information gained from this single component informs the behavior of the overall system The measurement of the build structure and comparison of its simulated digital counterpart allowed an evaluation on the overall system level The feedback between simulation and design poses the second layer of questions This process is taking part in a chain of processes starting with the generation of shape employing the nucleus engine as constraint solver followed by further steps in parametric software and finally the cnc fabrication The Dermoid project discusses the inherent possibilities and complexities that come along when feedback is introduced at different steps of the computational design process Top Decision Support System Approach for Construction Materials Selection Mansour Jadid and Mustafa Badrah The objective of this paper is to implement a decision support system for materials selection for projects under design or construction by consultants and owners The paper focuses on issues of materials approval selection criteria and materials information management The proposed system includes database and decision support components The database can enhance the functionality of the selection process as it provides a source of information to feed into the decision support component The decision support component relies on the quantitative methods of value engineering Construction involves processes that deal with materials in all stages of a project Decision making in project meetings requires the application of knowledge from many disciplines by all parties in the project teams to select materials and avoid delays for the project under construction Acquiring and recording information in a database regarding material quality durability specifications and maintenance requirements is a vital part of good project management practice It is anticipated that using such a system for materials selection will provide an improved tool that systematically enhances the selection process and enables upgrading the system during project life cycle Top Design Optioneering Multi disciplinary Design Optimization through Parameterization Domain Integration and Automation of a Genetic Algorithm David Gerber Shih Hsin Eve Lin Bei Penny Pan and Aslihan Senel Solmaz The overall performance of buildings is heavily impacted by design decisions made during the early stages of the design process Design professionals are most often unable to explore design alternatives and their impact on energy profiles adequately during this phase Combining parametric modeling with multi objective design optimization has been previously identified as a potential solution By utilizing parametric design and multi objective design optimization to influence design at the schematic level in the interest of exploring more energy efficient design configurations the H D S Beagle 1 0 tool was developed The tool enables the generation of design alternatives according to user defined parameter ranges automatically gathers the energy analysis result of each design alternative automatically calculates three objective functions and uses Genetic Algorithm to intelligently search rank select and breed the solution space for decision making Current case studies demonstrate our tool s ability to reduce design cycle latency and improve quality However the future work is to further investigate how to acclimate this process to accommodate early design stages and processes Top A Spatial Query Analysis Tool for Architects Ben Doherty Dan Rumery Ben Barnes and Bin Zhou We have developed a piece of software for finding shortest paths in buildings It consumes data produced by building designs documented in Revit It aids design creating simulations of where people would travel if they were omniscient and there were no flow restrictions this allows for circulation volumes to be predicted more quickly than through comparable agent simulations It also provides distance related information for regulatory checks mean euclidean distance calculation and a number of other types of analysis Our paper will introduce this tool and give some worked examples of its use Top Combining sensitivity analysis with parametric modeling to inform early design Julien Nembrini Steffen Samberger Andre Sternitzke and Guillaume Labelle The paper presents an approach which combines parametric geometric description techniques performance simulation and sensitivity analysis to achieve a quantitative analysis of the influence of selected design parameters on performance By using a scripting environment for parametric design linked to the EnergyPlus building simulation tool it becomes possible to automatically screen and simulate thermal behaviour over a selected design parameter space Then by defining one or several performance metrics their sensitivity to modification of design parameters can be computed through established statistical techniques for sensitivity analysis This approach provides quantitative insight into the level of influence of each parameter under scrutiny informing about changes altering enhancing or having only minor effect on performance This application of sensitivity analysis to parametric performative design is presented through the help of a case study Results and implications are discussed respective to their relevance to the early design phase of an architectural project The framework in definitive provides the design team with means to balance design intentions with performance aims Top A Multi Sensor Based Occupancy Estimation Model for Supporting Demand Driven HVAC Operations Zheng Yang Nan Li Burcin Becerik Gerber and Michael Orosz In the U S 40 of energy consumption is from buildings approximately 48 of which is consumed by heating ventilation and air conditioning HVAC systems Implementing demand driven HVAC operations is a way to reduce HVAC related energy consumption and ultimately to achieve sustainable building operation and maintenance This relies on the availability of occupancy information which determines peak off hour modes and impacts cooling heating loads of HVAC systems This research proposes an occupancy monitoring system that is built on a combination of non intrusive sensors that can detect indoor temperature humidity CO2 concentration door status light sound and motion Sensor data is communicated wirelessly and processed in real time using a back propagation neural network algorithm to estimate the number of occupants in a room Field tests are carried out in a shared office space over two month The test results show the effectiveness of each sensor in occupancy estimation and report an overall detection rate of 73 which indicates the ability of the proposed system to monitor the occupancy information of multi occupancy spaces in real time to support the implementation of demand driven HVAC operations Top Preliminary Investigation of the Use of Sankey Diagrams to Enhance Building Performance Simulation Supported Design William O Brien The diversity of building performance simulation BPS tools and the technologies and phenomena they support are continually growing However the vast majority of developments in the field are aimed at detailed design or even post design analysis and such do not place emphasis on influencing design The characteristics of this are numerous and detailed inputs and aggregated outputs The current research addresses the latter point by facilitating the communication of BPS results to building designers and their clients with the express intent on identifying predict building designs Specifically this paper will discuss a methodology for generating Sankey diagrams using data from BPS tools Specifically Sankey diagrams demonstrate a method for tracking every Joule of energy from the time it enters the building e g electrical supply to the time is leaves e g heat loss though the building envelope Sankey diagrams despite being over 100 years old 1 have rarely been applied to communicate building energy performance This is likely due to complexities related to defining useful and adverse heat gains are well defined For example the solar gains through a window may contribute to reducing heat loads increase the cooling loads or neither To complicate matters energy flows in buildings are not instantaneous particularly for passive solar buildings which are specifically intended to passively store solar gains for periods of as long as overnight This paper will introduce a methodology for creating Sankey diagrams to track all energy flows through a building and demonstrate it with a high performance passive solar house simple example shown below Top Automated Translation of Architectural Models for Energy Simulation Nathaniel Jones Kevin Pratt Lars Schumann David Bosworth and Andrew Heumann In the early stages of building design architects rapidly produce explore analyze and eliminate design options Ideally energy analysis should accompany and inform each design option but in reality the creation of building models for thermal simulation is too slow to keep up with the pace of design exploration This paper describes a framework for rapid energy analysis of architectural early design models The framework consists of a flexible modeling protocol to be followed by the user a standard communication protocol that may be implemented in virtually any architectural modeling software as a script or plug in and a translation protocol for automated production of energy models to be run in a stand alone program simultaneously with the modeling environment A prototype implementation of these protocols has successfully performed EnergyPlus analysis of early design stage architectural models created in SketchUp Grasshopper for Rhinoceros and 3ds Max This allows timely feedback on building energy consumption to be displayed side by side with an actively changing architectural model Top Dynamic Annual Metrics for Contrast in Daylit Architecture Siobhan Rockcastle and Marilyne Andersen Daylight is a dynamic source of illumination in architectural space creating diverse and ephemeral configurations of light and shadow within the built environment It can generate contrasting levels of brightness between distinct geometries or it can highlight smooth gradients of texture and color within the visual field Although there are a growing number of studies that seek to define the relationship between brightness contrast and lighting quality the dynamic role of daylight within the visual field is underrepresented by existing metrics This study proposes a new family of metrics that quantify the magnitude of contrast based visual effects and time based variation within daylit space through the use of time segmented daylight renderings This paper will introduce two new annual metrics Annual Spatial Contrast and Annual Luminance Variability These metrics will be applied to a series of abstract case studies to evaluate their effectiveness in comparing annual contrast based visual effects Top Performance Driven Design and Simulation Interfaces A Multi Objective Parametric Optimization Process Angelos Chronis Martha Tsigkari Evangelos Giouvanos Francis Aish and Anis Abou Zaki Despite the continuous development and integration of simulation interfacing tools in current architectural research the availability and operability of off the shelf tools has still not met the timeframes and performance requirements of current architectural practice The complexity and demanding performance goals of contemporary large scale projects often require innovative approaches as well as the development of novel simulation interfacing tools to meet these requirements This paper reports on a multi objective optimization process aiming at reducing incident solar radiations whilst optimizing daylight penetration for the façade of a large scale office building This was achieved through the combined use of a parametric model and a genetic algorithm along with an integrated data set of pre computed results To minimize the resources demand of analyzing the plethora of potential configurations of the façade a number of strategically defined modular cases were modeled and simulated using bespoke interfacing tools to produce a database of results This database was then linked to a parametric model providing real time feedback and allowing for an exhaustive search of design configurations To further explore potential optimal solutions a multi objective optimization process using a genetic algorithm also linked to the results database was implemented The overall optimization process provided invaluable insight to the design problem at hand Top Climatic based consideration of Double skin Façade system comparative analysis of energy performance of a Double Skin Facade Building in Boston Mona Azarbayjani This paper focuses on investigation of climatic based design for double skin façade system in a case study addition to cambridge public library in Boston The double skin façade is an architectural phenomenon driven by the aestheticdesire for an all glass façade and the practical desire to have naturalventilation for improved indoor air quality in buildings Until recently theuse of double skin façades had become more popular in many buildings in Europe While a great deal of interest exists in learning how to integrate DSFs into our current architecture there is a little knowledge or demonstration of how the concept might work in a city such as Chicago The primary goal of this research is to clarify the state of the art performance of DSFs so that designers can assess the value of these building concepts in meeting design goals for energy efficiency ventilation productivity and sustainability In this study building envelope performance is investigated by modeling energy performance of the building in comparison with actual energy consumption Top A visual performative language of façade patterns for the Connected Sustainable Home Sotirios D Kotsopoulos Federico Casalegno Guglielmo Carra Wessley Graybill and Bob Hsiung An examination of the aesthetic and performative advantages in optimizing electrochromic technology in residential architecture is presented The association between a specific architectural element of a prototype house a glass façade involving 100 electrochromic windows and the adjustment of the natural lighting conditions in the house interior is treated algorithmically The façade operates as a dynamic filter between exterior and interior it filters solar radiation and heat by allowing the modification of the chromatism and light transmittance of each individual window Varying the number and the distribution of the active windows on the façade permits the regulation of the incoming natural light and affects the visual presence and the energy performance of the house A generative grammar producing the language of the optimum in terms of interior illumination performance façade patterns is presented The novelty of this research is that it concerns real time permutation of two distinct computational systems qualitative visual and quantitative performative The described system yields optimum patterns for the South façade of the prototype house through mutual adjustment of electrochromic window activation and interior illumination intensity Shape grammar formalism and digital simulation software are used for the task Top Urban Network Analysis A new toolbox for measuring city form in ArcGIS Andres Sevtsuk and Michael Mekonnen We introduce an open source Urban Network Analysis UNA toolbox for ArcGIS which can be used to compute five types of centrality measures on spatial networks Reach Gravity Index Betweenness Closeness and Straightness Though primarily developed for the analysis of urban street and building networks the toolbox is equally suited for other spatial networks such as building layout highway or utility networks Unlike previous network analysis tools that operate with two network elements nodes and edges the UNA tools include a third network element buildings that are used as spatial units of analysis for all measures Neighboring buildings on the same street segment can therefore obtain different accessibility results UNA tools allow buildings to be weighted according to their characteristics more voluminous more populated or otherwise more important buildings can be specified to have a proportionately stronger effect on the analysis outcomes The paper demonstrates its application in Cambridge and Somerville MA Top The parametric exploration of spatial properties Coupling parametric geometry modeling and the graph based spatial analysis of urban street networks Sven Schneider Martin Bielik and Reinhard König Parametric modeling is a powerful tool that allows designers to explore a wide range of variants of their design concept However when evaluating the spatial properties of such variants the tools for parametric modeling offer little support While on the other hand a wide range of methods exists for analyzing geometry in terms of its spatial properties via graph based measures the available software for analyzing these properties offers limited capabilities for changing the geometry After analyzing the geometry design changes then have to be made in another program which hinders the design workflow and with it the desinger s willingness to explore a wide range of variants This paper describes an approach that attempts to bridge the gap between parametric geometry modeling and methods for measuring the spatial properties of this geometry To this end we developed a component for a well known parametric modeling software package for graph based analysis This component is able to interpret segment maps from parametric line drawings e g urban networks and calculates centrality integration and betweenness choice for different radii We demonstrate the applicability of the method in a test scenario Top Spatial Simulation Model of Urban Retail System Sanna Iltanen The paper introduces a dynamic spatial model of urban retail system in which the retail units of different sizes and types compete with each other and the households continuously re evaluate their shopping orientation The simulation model has been built within network city theory framework especially Gabriel Dupuy s 1991 three level model of urban networks In the model spatial approach is emphasized through morphological types of retail units and transportation network as primary spatial structure of an urban agglomeration The model enables observation how different boundary conditions set by the typology and transportation networks effect on the spatial organization of retail units in urban environment The model is based on three major elements 1 infrastructural level topological transportation network 2 level of production and consumption retail units and 3 individual level households The simulation model utilizes both modern agent based modeling techniques and methodologies of traditional spatial interaction models e g Wilson Bennett 1985 The interest lies on the process in which the competing retail units act as independent agents and locate themselves in urban structure One of the objectives is to compare different accessibility measures that essentially influence consumer utilities and also on the clustering degree of retail units Particularly the focus is on urban phase transitions and resulting morphological change The case study has been executed in Helsinki city region in Finland Top Automatic Building Design with Genetic Algorithms and Artificial Neural Networks Negin Behboudi Fouad Butt and Abdolreza Abhari It is our goal to develop an automatic system that employs soft computing
