    and efficiency characteristics of buildings A key step in this process is the creation of the actual diversity factor profiles for occupancy and various energy end uses such as lighting plug loads and HVAC Creation of these model inputs is conventionally a tedious process of site surveys interviews or temporary sensor installation Sometimes measured energy data can be used to create these schedules however there are many challenges especially when the sensor network available is large or unorganized This paper describes a process applying a series of knowledge discovery filters to screen data quality weather sensitivity and temporal breakouts from large nonresidential building performance datasets collected by building management and energy information systems BMS EIS These screening techniques are used to qualify the desirability for calibrated model diversity schedule creation from a forensic perspective A diurnal pattern filtering technique is then applied that automatically extracts frequent daily performance profiles which can then be normalized and used as model inputs according to conventional industry techniques The process is applied on a raw dataset of 389 power meter data streams collected for eight years from the EIS of a campus of 32 higher education buildings The results are discussed in the context of time and effort savings for creating urban and building scale simulation model inputs Top Multiobjective Optimization of Structure and Visual Qualities Kirk Martini The paper describes and demonstrates an optimization tool that combines methods developed independently in the fields of structural engineering and fine art Optimization has a long history in structural engineering Most commonly structural optimization seeks a configuration that minimizes material volume subject to constraints on strength and stiffness Metaheuristic search methods such as genetic algorithms have been widely applied to structural optimization problems Such methods have also been applied in the field of evolutionary art This field seeks to produce aesthetic images or objects through an iterative search guided by visual rather than functional objectives The paper presents the Variable Evolutionary Strategy for Pareto Optimization Vespo and demonstrates its use to integrate visual objective functions like those in evolutionary art with technical objective functions and constraints in structural optimization The goal is to aid a designer in developing an efficient structure with desired visual qualities The work is motivated in part by the prominent trend in contemporary architecture toward randomized free form structures Top Decomposition Strategies for Building Envelope Design Optimization Problems Steve Barg Forest Flager and Martin Fischer The design of a building s envelope including exterior walls glazing and shading elements has a significant impact on the life cycle cost and environmental impact of the facility Computational Design Optimization CDO methods have been developed to assist architects and engineers to systematically search through large numbers of design alternatives to identify high performing building envelope solutions This paper presents a method to quantitatively compare different CDO approaches in terms of solution quality and computational efficiency To demonstrate the method we compare four CDO methods two single level genetic algorithms a single level gradient based algorithm that maps continuous solutions back to discrete options and a bi level decomposition with a gradient based algorithm operating on continuous variables nested within a genetic algorithm operating on discrete variables The example chosen for benchmarking purposes is a midrise apartment building in Chicago The results show that the all in one multiple objective genetic algorithm is the most computationally efficient and produced superior solution quality The limited breadth of the current results does not allow general conclusions about the methods but does demonstrate a methodology for further evaluation of optimization techniques Top Optimizing Creatively in Multi Objective Optimization Yassin Ashour and Branko Kolarevic Designers will always face the challenge of designing well performing buildings using what are often conflicting and competing objectives Early stage design decisions influence significantly the final performance of a building and designers are often unable to explore large numbers of design alternatives with respect to the performative criteria set for the project This research outlines a creative optimization workflow using a Multi Objective Optimization MOO engine called Octopus that runs within Grasshopper3D a parametric modeling tool and simulation software DIVA for daylight factor analysis The workflow utilizes a creative optimization tool which allows the designer to explore sort and filter solutions and analyze both quantitatively and qualitatively the trade offs of the resultant design solution space It enables the designer to visually compare alternative solutions in a gallery and subsequently analyze trade offs through a radar based chart parallel coordinate plot graphs and conditional domain searches This feedback tools allows the designer to quickly and efficiently identify potential solutions for either design development or to select preferred solutions for further optimization i e optimizing creatively A retrospective design case study the De Rotterdam building is used to demonstrate the application of the tools The workflow demonstrates the ability to reduce design latency and to allow for better understanding of design solutions Additional research is needed to better understand the application of MOO in the early stages of design and the further improvement of the creative optimization tools to accommodate the designer s need for a more dynamic and synergistic process Top A Multi Agent Systems for Design Simulation Framework Experiments with Virtual Physical Social Feedback for Architecture David Jason Gerber Evangelos Pantazis Arsalan Heydarian and Leandro Marcolino This paper presents continuing research on the development of multi agent systems MAS for integrated and performance driven architectural design It presents the development of a research framework that bridges architecture and engineering through a series of simulation based experiments The research is motivated to combine multiple design agencies into a system for managing and optimizing intricacy across complex architectural form on objectives and contexts The research anticipates the incorporation of feedback from real world human behavior and user preferences with physics based structural form finding and environmental analysis data The framework is a multi agent system that provides design teams with informed design solutions which simultaneously optimize and satisfy competing design objectives The initial results of the multi agent systems approach for building structures hypothetical and real are measured in terms of the level of lighting improvements and qualitatively in geometric terms Critical to the research is the elaboration of the system and the feedback loops that are possible in using the multi agent systems approach Top Exploratory Sequential Data Analysis for Multi Agent Occupancy Simulation Results Simon Breslav Rhys Goldstein Azam Khan and Kasper Hornbæk In this paper we apply the principles of Exploratory Sequential Data Analysis ESDA to simulation results analysis We replicate a resource consumption simulation of occupants in a building and analyze the results using an open source ESDA tool called UberTagger previously only used in the human computer interaction HCI domain We demonstrate the usefulness of ESDA by applying it to a hotel occupant simulation involving water and energy consumption We have found that using a system which implements ESDA principles helps practitioners better understand their simulation models form hypotheses about simulated behavior more effectively debug simulation code and more easily communicate their findings to others Top Occupant Aware Indoor Monitoring for Enhanced Building Analysis Dimosthenis Ioannidis Stelios Krinidis Anastasios Drosou Dimitrios Tzovaras and Spiridon Likothanassis In this paper a novel cost effective and robust occupancy monitoring system is presented which is based on a fuzzy confidence voting algorithm utilizing spatial height histograms Spatial height histograms are invariant to rotations and translations providing this way a desirable feature to occupancy measurement systems and when combined with distance coefficients can fix an occupancy feature vector which is the main source for the fuzzy confidence voting occupant tracking algorithm The proposed occupancy extraction system can be efficiently applied to multi space environments using a privacy preserving multi camera cloud Statistics per building space and occupant can be finally extracted by the system The experimental results will illustrate its robustness accuracy and efficiency on occupancy extraction Top A System for Tracking and Visualizing Social Interactions in a Collaborative Work Environment Mani Williams Jane Burry Asha Rao and Nathan Williams This paper presents our work on indoor tracking and demonstrates its capacity as a data collection system for the study of socio spatial interactions that occur in a collaborative work environment Deployed at a recent week long international design workshop our system was able to track the movements of more than fifty people from various roles and generate live visualizations In this paper we will present the data collection system and the system configurations the complete dataset collected and sample visualization scripts to stimulate further research in the area of people interaction study and its relation to spatial usage Top MODYPLAN Early Stage Hospital Simulation with Emphasis on Cross Clinical Treatment Chains Gabriel Wurzer Wolfgang E Lorenz Matthias Rössler Irene Hafner Niki Popper and Barbara Glock Health trusts are aiming to consolidate the clinical landscape The provision of medical services now handled by individual clinics is to be transformed such that the patient volume can be redirected between different specialized service providers As implication hospital planning needs to embrace the subject of cross clinical development rather than looking at each facility in isolation In this context we have been developing MODYPLAN a cross clinical simulation for early stage architectural planning Our software takes the patient volume as input and redirects it to different facilities each one having a different spatial layouts and treatment capacity As outputs we obtain the utilization and occupancy of each service unit on which we can base further analysis concerning bottlenecks Furthermore different configurations of the clinical landscape can be compared facilitating a multi faceted discussion among stakeholders clinical providers their staff and patients As audience we target hospital administration architects and process designers preparing or working on tenders Such an early application of cross clinical simulation is to the best of our knowledge yet unprecedented Top Multi Objective Genetic Algorithms for the Minimisation of the Life Cycle Carbon Footprint and Life Cycle Cost of the Refurbishment of a Residential Complex s Envelope A Case Study Yair Schwartz Rokia Raslan and Dejan Mumovic Life Cycle Analysis LCA is an environmental assessment and management framework that aims to simplify the decision making processes of manufacturing and consumption with regard to their environmental impact In the built environment LCA is often used as a comparative tool that helps in choosing one design alternative over another Most LCA studies compare a limited number of design alternatives due to the complexity of the method The main goal of this study is to examine the various Life Cycle aspects of a refurbishment of a case study and explore the potential of using Multi Objective Genetic Algorithms MOGA with Dynamic Thermal Simulation Tool EnergyPlus to find optimal refurbishment measures in terms of Life Cycle Carbon Footprint LCCF and Life Cycle Cost LCC over an assumed life span of 60 years Results show that MOGA successfully identified optimal design solutions when taking into account both basic design aspects such as window to wall ratio or envelope build ups but also more detailed ones such as thermal bridges insulation and the use of different fuel types for energy generation Top Optimization of Passive Cooling Control Thresholds with GenOpt and EnergyPlus Alexandra R Rempel and Stephen J Remington Passive cooling strategies e g shading natural ventilation use of thermal mass can effectively reduce a building s cooling load during hot summer weather Such techniques have been well studied with the provision that precedent work assumes operable shading devices windows and vents are operated according to pre determined schedules or setpoints This work in contrast investigates numerical optimization of the setpoints themselves Among space types most useful for studying passive cooling are unconditioned zones such as sunspaces because they can easily overheat on sunny days and because heat loss pathways in the forms of wind cool night air cold night skies ground contact and precipitation can sum to a sizable proportion of the cooling load in temperate climates At the same time the transition of a given path between heat gain and loss may be undetectable to an occupant causing manual controls to be ineffective and mechanical controls to be of interest Here GenOpt was used to manage optimizations of shading and natural ventilation control thresholds as well as auxiliary optimizations of shading type material and position vent area and thermal mass quantities within a field validated EnergyPlus sunspace model Results predicted that controls operated according to optimized setpoints should maintain peak indoor temperatures 8 10 C 14 18 F below outside air temperatures during the hottest August afternoons of the sunspace s native American Pacific Northwest climate In addition optimization data established clear priorities among field configurations to be tested showing the potential to simplify subsequent field validation greatly Top Toward Pre Simulated Guidelines for Low Energy High Rise Residential Design in Megacities Holly Samuelson Apoorv Goyal Sebastian Claussnitzer Alejandra Romo Castillo Yujiao Chen and Arpan Bakshi In order to improve early decision making for similar projects the authors used parametric energy simulation with the eventual aim of providing pre design guidance for multiple teams of architects and policy makers The authors investigated high rise multi family residential buildings in three megacities as case studies They tested the impact of various design parameters on different energy objectives that they anticipate including in their pre design resource The research included three parts 1 The authors identified synergies and trade offs in terms of early design decisions when designing for different energy objectives including a reducing annual energy consumption b shaving peak energy demand and c increasing passive survivability i e maintaining the safest interior temperatures in an extended power outage 2 They performed sensitivity analyses to identify the impact of various design parameters which included building form window to wall ratio envelope construction shading design and others in the presence of confounding variables such as varying internal loads 3 The authors investigated the impact of urban context Since in generalized guidelines the future building site is unknown the authors tested a method for generating an urban context based on the floor area ratio and maximum building heights of an urban district These tests support the larger idea of eventually creating a comprehensive pre simulated resource for pre design Top A Digital Design and Fabrication Library Stylianos Dritsas The goal of our system for lack of better name at moment named as Alpha is to offer an integrated approach to digital design and fabrication with capabilities beyond computer aided design and manufacturing We attempt this to identify new modes of digital design thinking and to address the broader picture that is the challenge of translating between design and its production It is to understand the complexity of design and its implications in production to enable and perform architectural design analysis rationalization and design performance optimization We integrate visual geometric modeling and simulation components and non visual mathematical modeling and numerical optimization techniques The intended audience at the current early stage of development is the research community in digital design and fabrication and design education with later goal of expanding to production Top Aware Design Models Martin Tamke Appearing almost alive a novel set of computational design models can become an active counterpart for architects in the design process The ability to loop sense and query and the integration of near real time simulation provide these models with a depth and agility that allows for instant and informed feedback Introducing the term Aware models the paper investigates how computational models become an enabler for a better informed architectural design practice through the embedding of knowledge about constraints behaviour and processes of formation and making into generative design models The inspection of several computational design projects in architectural research highlights three different types of awareness a model can possess and devises strategies to establish and finally design with aware models This design practice is collaborative in nature and characterized by a bidirectional flow of information The concept of the aware model addresses hence the current infrastructures of digital design models and processes which impede technologically and methodologically feedback between disciplines and processes Top Curve Folded Form Work for Cast Compressive Skeletons Shajay Bhooshan Vishu Bhooshan Ashwin Shah Henry Louth and David Reeves The research described in this paper explores the synergy between the methods of form finding for funicular loads with curved crease folding CCF The paper will propose a two step process that combines a form finding method that finds the form under vertical loading and with a mesh perturbation method that solves for planarity and develop ability constraints The resulting geometry will be shown to be amenable to construct curve crease folded moulds for concrete casting The paper will also describe the design of a demonstrative prototype a self supporting structure composed of bar elements that are formed by casting concrete into molds that are curve folded from sheet material Top A Physical and Numerical Simulation Strategy to Understand the Impact of the Dynamics in Air for the Design of Porous Screens Mani Williams Rafael Moya Daniel Prohasky Mehrnoush Latifi Khorasgani Simon Watkins Mark Burry Jane Burry and Philip Belesky This paper describes a virtual and physical design and prototyping strategy intended to aid designers to understand the relational dynamic between airflow and porous screens for building facades at the conceptual design stage The strategy consists of three main components 1 A prototyping phase involving a combination of computer aided modeling CAM physical additive and subtractive fabrication 2 A virtual simulation phase using computational fluid dynamics CFD software 3 A physical simulation phase of experimental fluid dynamics EFD using a miniature wind tunnel MWT and microelectronic measurement systems MEMS that measure wind speed air temperature and relative humidity The design strategy supports the designer to make design decisions based on relevant feedback from both CFD and EFD methods covering a vast design solution space The tools utilized within this design strategy are presented as a kit containing parts that are relatively inexpensive easy to assemble and have been successfully user tested at an
