summary	This research focus on the application of Theory of Games and asymmetry information to the AEC sector underling the impact of these theories to the supply chain and in particular on the evolution of the client role in a Building Information Modeling process. The mentioned theories used to be applied to macroeconomic fields, but allowed the researchers to understand the evolution of the sector and the internal behavior of the team. This analysis of team behaviors permits to grasp how the contractual frame could hold up the natural trend of the market to collaborate, which leads the sector to improve itself. The Theory of Games could be adopted as a hermeneutic tool for understanding actions and agreements to which the various parties achieve. The research provided a global analysis on the evolution of the client role in a cyclical process. Further development of the research will be the application of the theory to a real case study to catch the real team behavior in a collaborative environment.

summary	Smart Growth is an urban design movement initiated by Environmental Protection Agency (EPA) in the United States (Smart Growth America, 2019). The regulations of Smart Growth control urban morphologies such as building height, use, position, section configurations, faÃ§ade configurations, and materials, which have an explicit association with energy performances. This research aims to analyze and visualize the impact of Smart Growth developments on environmental performances. This paper presents a parametric modeling and simulation framework for Smart Growth developments that can model the potential community development scenarios, simulate the environmental footprints of each parcel, and visualize the results of modeling and simulation. We implemented and examined the proposed framework through a case study of two Smart Growth regulations: Columbia Unified Development Code (UDC) in Missouri (City of Columbia Missouri, 2017) and Overland Park Downtown Form-based Code (FBC) in Kansas City (City of Overland Park, 2017, 2019). Last, we discuss the implementation results, the limitations of the proposed framework, and the future work. We anticipate that the proposed method can improve stakeholders' understanding of how Smart Growth developments are associated with potential environmental footprints from an expeditious and thorough exploration of what-if scenarios of the multiple development schemes.

title	Optimization of Window-Wall-Ratio using BIM-based Energy Simulation
doi	https://doi.org/10.52842/conf.caadria.2017.397
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 397-405
summary	In this research, sensitivity analysis is applied to investigate the impact from U-values of walls, U-value of windows, and the window-to-wall ratio. The purpose is to find the co-relationship between those parameters with the building energy performance, including embedded energy in materials and operational energy during the lifecycle. Building Information Modeling (BIM) is used as a platform to obtain the material quantities and carry on energy simulation. A case study is applied for a manufactory plant in Suzhou, China. By applying both local sensitivity analysis and global sensitivity analysis, it is found that thermal properties of walls have insignificant impact on Operational Energy to Embodied Energy (OE-EE) relationship of Window-Wall-Ratio (WWR) whereas changing thermal properties of windows affects the OE-EE relationship behaviour of WWR. Lowering U-value of windows brings positive impact to the OE-EE relationship of WWR, and vice versa. Therefore, suggestions are made as reducing/increasing U-value of windows while increasing/decreasing the WWR of building.

title	Algorithmic Design and Analysis Fusing Disciplines
doi	https://doi.org/10.52842/conf.acadia.2017.028
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 28-37
summary	In the past, there has been a rapid evolution in computational tools to represent and analyze architectural designs. Analysis tools can be used in all stages of the design process, but they are often only used in the final stages, where it might be too late to impact the design. This is due to the considerable time and effort typically needed to produce the analytical models required by the analysis tools. A possible solution would be to convert the digital architectural models into analytical ones, but unfortunately, this often results in errors and frequently the analytical models need to be built almost from scratch. These issues discourage architects from doing a performance-oriented exploration of their designs in the early stages of a project. To overcome these issues, we propose Algorithmic Design and Analysis, a method for analysis that is based on adapting and extending an algorithmic-based design representation so that the modeling operations can generate the elements of the analytical model containing solely the information required by the analysis tool. Using this method, the same algorithm that produces the digital architectural model can also automatically generate analytical models for different types of analysis. Using the proposed method, there is no information loss and architects do not need additional work to perform the analysis. This encourages architects to explore several design alternatives while taking into account the design’s performance. Moreover, when architects know the set of design variations they wish to analyze beforehand, they can easily automate the analysis process.

title	Resilience Design
source	SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017
summary	The chosen theme, Resilience Design, evidences the researchers’ concern about issues related to our reality of climate change and natural disasters, associated with the states of vulnerability and risk, having wide effects on society and the way we inhabit territories. These matters are fundamental and highly relevant for the disciplines and in the fields of design and architecture, as they are also important for collaborative work with areas emerging from the arts and human sciences. Thinking about Resilience Design is to set ourselves on new scenarios of reflection and action which, supported by transdisciplinary thinking and collaborative design, allow us to develop a new approach towards our territories and their demands, one that is more contextualized and adjusted to their current and future requirements, a starting point to establish the key elements to drive change in our cities and society. In this sense, technology and digital development, parametric design, the use of Information and Communication Technologies (ICT) and Geographic Information Systems (GIS), in addition to work done with Building Information Modelling (BIM), among many others, have been delivering an enormous amount of tools and possibilities of interaction with living in society, leading to a substantive change in the way of understanding and relating to the built environment and the territories where buildings are sit. This demands a strong commitment to Social Responsibility from our disciplines, besides the necessary landing of cutting-edge technological and digital research and development onto our diverse realities, in order for them to be put at the service of communities in vulnerable environments or with a marked condition of risk, which are subject to constant processes of resilience. Working on Resilience Design allows to support research and productive processes, plus the appearance of new technologies in interdisciplinary contexts, which greatest value is to impact the processes of teaching and professional practice in the different areas related to human habitation. The new professionals will have to take action and immerse themselves into these new scenarios of change and constant adjustment.

title	Bibil: A Performance-Based Framework to Determine Built Form Guidelines
doi	https://doi.org/10.52842/conf.acadia.2017.630
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 630- 639
summary	City built-form guidelines act as durable constraints on building design decisions. Such guidelines directly impact energy, comfort and other performance conditions. Existing urban design and planning methods only consider a narrow range of potential design scenarios, with rudimentary performance criteria, resulting in suboptimal urban designs. Bibil is a software plugin for the Rhinoceros3D/Grasshopper3D CAD modeler that addresses this gap through the synthesis of design space exploration methods to help design teams optimize guidelines for environmental and energy performance criteria over the life cycle of the city. Bibil consists of three generative and data management modules. The first module simulates development scenarios from street and block information through time, the second designs appropriate architectural typology, and the third abstracts the typologies into a lightweight analysis model for detailed thermal load and energy simulation. State-of-the-art performance simulation is done via the Ladybug Analysis Tools Grasshopper3D plugin, and further bespoke analysis to explore the resulting design space is achieved with custom Python scripts.This paper first introduces relevant background for automated exploration of urban design guidelines. Then the paper surveys the state-of-the-art in design and performance simulation tools in the urban domain. Next the paper describes the beta version of the tool’s three modules and its application in a built form study to assess urban canyon performance in a major North American city. Bibil enables the exploration of a broader range of potential design scenarios, for a broader range of performance criteria, over a longer period of time.

title	Building Information Modeling data interoperability for Cloud-based collaboration: Limitations and opportunities
source	International Journal of Architectural Computing vol. 15 - no. 3, 187-202
summary	Collaboration within Building Information Modeling process is mainly based on the manual transfer of document files in either vendor-specific formats or neutral format using Industry Foundation Classes. However, since the web enables Cloud-based Building Information Modeling services, it provides an opportunity to exchange data with web technologies. Alternative data sharing solutions include the federation of Building Information Modeling models and an interchange hub for data exchange in real time. These solutions face several challenges, are vendor locked, and integrate Building Information Modeling applications to a third new system. The main objective of this article is to investigate current limitations as well as opportunities of Cloud interoperability to outline a framework for a loosely coupled network-based Building Information Modeling data interoperability. This study explains that Cloud-Building Information Modeling data exchange needs to deploy major components of Cloud interoperability such as Cloud application programming interfaces, data transfer protocols, data formats, and standardization to redefine Building Information Modeling data flow in Cloud-based applications and to reshape collaboration process.

title	Representing the Aesthetics of Richard Meier’s Houses Using Building Information Modeling
doi	https://doi.org/10.52842/conf.acadia.2017.062
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 62-71
summary	Beyond its widespread use for representing technical aspects and matters of building and construction science, Building information modeling (BIM) can be used to represent architectural relationships and rules drawn from aesthetic theory. This research suggests that BIM provides not only vocabulary but also syntactical tools that can be used to capture an architectural language. In a case study using Richard Meier’s language for single-family detached houses, a BIM template has been devised to represent the aesthetic concepts and relations therein. The template employs parameterized conceptual mass objects, syntactical rules, and a library of architectonic elements, such as walls, roofs, columns, windows, doors, and railings. It constrains any design produced using the template to a grammatically consistent expression or style. The template has been used as the starting point for modeling the Smith House, the Douglas House, and others created by the authors, demonstrating that the aesthetic template is general to many variations. Designing with the template to produce a unique but conforming design further illustrates the generality and expressiveness of the language. Having made the formal language explicit, in terms of syntactical rules and vocabulary, it becomes easier to vary the formal grammar and concrete vocabulary to produce variant languages and styles. Accordingly, this approach is not limited to a specific style, such as Richard Meier's. Future research can be conducted to demonstrate how designing with BIM can support stylistic change. Adoption of this approach in practice could improve the consistency of architectural designs and their coherence to defined styles, potentially increasing the general level of aesthetic expression in our built environment.

summary	This paper presents a method for translating physical interaction with design objects into parametric relationships. A framework of the method is created to automate the generation of parametric equations as modeling constraints. The prototypes developed for this work link digital models with their physical counterparts to create a hybrid and tangible interface that enables user interaction. The prototypes investigate linear and non-linear types of object relationships for creating parametric models. The results demonstrate a novel approach in architectural design that assists users in creating complex geometric relationships through intuitive interaction.

summary	This paper examines the current state of the conventional Design-Bid-Build project, wherein design intentions are manually translated to construction directives by subcontractors based on industry-specific details. This process exacerbates a dilemma in design and construction; that often the designer may be unaware of certain details that are involved in fabricating and assembling building components. Research for Knowledge Base for Architectural Detailing (KBAD) proposes a system that takes advantage of current CAD software and programming language, bringing together the information provided by and important to the design team with the data required by the subcontractor to accurately produce architectural components, during the design phases of a project. The trade of architectural precast concrete is used to demonstrate the potential of such a system. Solid modeling, visual scripting, and programming language techniques working towards KBAD are described. Possible variations of architectural precast concrete panels, detailed with window openings, reveals, and embed plates, are presented.

summary	The research presents an application of HBIM to the recovery process and design, which allows to highlight some potentialities and criticalities of what has become an important instrument in the documentation and conservation of architectural heritage. The object of the research is the Temple di Bacco, built by Lord Girmthorpe as his final resting place and located within the gardens of Villa Cimbrone, Ravello (SA).The survey has presented several difficulties due to the particular configuration of the site, very steep, with very limited space around the object. If on the one hand the TLS obvious to the lack of edges of cylindrical objects, on the other hand it poses problems for the tangency of the scan points. The Scan to BIM methodology has proven to be effective and has allowed to overcome the difficulties associated with the conformation of the artefact and of the site, in the study of the analyzed object. In conclusion, some assessments and results are reported, aimed at sharing and defining strategies and methodologies of scientific validity regarding the application of the HBIM model to a process of recovery and consolidation of an existing building object.

summary	The term Building Information Model emerged in 1992. It has evolved over time and has its meaning currently associated with an object-oriented modeling technology and an associated set of processes to produce, communicate and analyze building models. Its origin is related to several other, older terms. This paper registers the evolution of BIM and related definitions over time by means of a systematic literature review. We present a list of BIM-related terms and their meanings, organized by date of emergence, and charts showing which ones are most used over time, contributing to better understanding of the meaning of BIM.

title	A Parametric Approach To Simulating Use-Patterns in Buildings - The Case Of Movement

summary	We describe one of the three core use-pattern building blocks of a parametric approach to simulating use-patterns in buildings. Use-patterns are modeled as events which use specified descriptions of spaces, actors and activities which constitute them. The simulation system relies on three fundamental patterns of use - move, meet and do. The move pattern is considered in detail in this paper with specific reference to what we term the partial knowledge issue. Modeling decision making about how to move through the space (what path to take) depends on modeling the actor's partial access to knowledge. Visibility is used as an example of partial knowledge. The parametric approach described in the paper enables the clear separation of syntactical and semantic conditions which inform decisions and the coordination of decisions made by agents in a simulation of use-patterns. This approach contributes to extending the analytical capability of Building Information Models from the point of view of evaluating how a proposed building design may be used, given complex, interrelated patterns of use.

summary	Post-Occupancy Evaluation (POE) as an integrated field between architecture and sociology has created practical guidelines for evaluating indoor human behavior within a built environment. This research builds on recent attempts to integrate datafication and machine learning into POE practices that may one day assist Building Information Modeling (BIM) and multi-agent modeling. This research is based on two premises: 1) that the proliferation of Bluetooth Low Energy (BLE) technology allows us to collect a building user’s data cost-effectively and 2) that the growing application of machine learning algorithms allows us to process, analyze and synthesize data efficiently. This study illustrates that the mobile platform HalO can serve as a generic tool for datafication and automation of data analysis of the movement of a building user. In this research, the iOS mobile application HalO, combined with BLE beacons enable building providers (architects, developers, engineers and facility managers etc.) to collect the user’s indoor location data. Triangulation was used to pinpoint the user’s indoor positions, and k-means clustering was applied to classify users into different gathering groups. Through four research procedures—Design Intention Analysis, Data Collection, Data Storage and Data Analysis—the visualized and classified data helps building providers to better evaluate building performance, optimize building operations and improve the accuracy of simulations.

summary	With the use of the concept Central Activities Zone in the Shanghai City Master Plan (2017-2035) to replace the traditional concept of Central Business District, core areas such as Shanghai Lujiazui will be given more connotations in the future construction and development. In the context of todays continuous urbanization and high-speed capital flow, how to identify the development status and vitality characteristics is a prerequisite for creating a high-quality Central Activities Zone. Taking Shanghai Lujiazui sub-district etc. as an example, the vitality value of weekday and weekend as well as 19 indexes including density of functional facilities and building morphology is quantified by obtaining multi-source big data. Meanwhile, the correlation between various indexes and the vitality characteristics of the Central Activities Zone are tried to summarize in this paper. Finally, a neural network regression model is built to bridge the design scheme and vitality values to realize the prediction of the vitality of the Central Activities Zone. The data analysis method proposed in this paper is versatile and efficient, and can be well integrated into the urban big data platform and the City Information Modeling, and provides reliable reference suggestions for the real-time evaluation of future urban construction.

summary	Until today, on-site robotic construction processes in landscape architecture have been limited to predefined and controlled environments like road building or mining pits. We are presently developing an autonomous walking excavator that paves the way for new and advanced on-site design strategies. The shift towards robotic construction in terrain modeling and landscape architecture demands an adaptive design approach, where the resulting topology is inherently linked to landscape performance and the local conditions of a site. This paper discusses the computational design tools that may help redefine how design and construction processes can be better adapted to real-time topological and sensory data. This approach will, in due time, revolutionize how designers think, act and play with contemporary landscapes robotically, and reimagine their intrinsic relationship to infrastructure.

summary	Growing number of Building Information Modeling (BIM) applications have supported the automated assessment of building design and its quality in the early phase of design. For increasing the accuracy and fineness of assessment, rule interpretations require logical base and standardization of analysis process. Therefore, some government-funded research projects have focused on this rule-making process separated from the rule-checking process. Specifically, KBimLogic is a logic rule-based mechanism designed for the building permit related rules in Korea Building Act sentences. As a com-puter-readable definition of a rule, KBimCode has been developed to be executed in actual rule-checking software. The limitation of such code is the visibility to the rule experts who are usually non- or novice programmers. This paper describes much intuitive way of defining and generating KBimCode through KBim Visual Language. User can easily query the building element and method through the immanent connection with KBimLogic database. By using the KBim Visual Language, various types of rules written in design guideline, international standardization, and national acts can be easily interpreted into computer-readable formats such as KBimCode in order to proceed with the automated rule-checking.

title	Green Standard for Energy and Environmental Design - The Development of an Assessment System Based on a Green BIM Template

summary	To construct a building that meets the requirements of certification in terms of environmental friendliness, there must be a process that considers the certification criteria from the initial design phase. However, there are numerous complicated task performance procedures to analyse many required items in detail as well as perceive and apply the data requirements efficiently. Currently, Building Information Modeling (BIM) is gaining attention as a solution for environmental problems in architecture. BIM shows precisely how a virtual building is modelled in the real world, thereby providing an objective information and analysis through a simulation. However, the result values of BIM library or modelling may turn out differently as a result of the work environment of designers or users that is not standardized. Therefore, this study applies the modelled and extracted BIM data using the template and library established in the BIM add-in planning and design phase to review in advance the Green Standard for Energy and Environmental Design (G-SEED) assessment by item and manual input of users with the BIM-based (add-in) G-SEED assessment system, thereby providing support to enable users to establish specific strategies in designing green buildings.
