title	Data Sharing for Sustainable Building Assessment
source	International Journal of Architectural Computing vol. 10 - no. 4, 555-574
summary	Sustainable design assessment requires information, which is aggregated from different phases of a building design, and evaluated according to criteria specified in a ‘sustainable building rating system.’ In the architecture engineering and construction (AEC) domain much of the necessary information is available through open source data standards such as Industry Foundation Classes (IFC). However, no single standard that provides support for sustainability assessment completely suffices as a data structure. This paper explores the augmentation of the Construction Operations Building information exchange (COBie) model, as an intermediary data structure, to bridge between requirements of the Leadership in Energy and Environmental Design (LEED) rating system and a building information model. Development of a general framework for data sharing and information management for LEED assessments is illustrated through an implementation of a prototype using functional databases.The prototype checks and augments available data as needed, which is used to populate LEED submission templates.

title	Data sharing for sustainable assessments: Using functional databases for interoperating multiple building information structures
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 193–202

summary	This paper presents the development and implementation of an automatic sustainable assessment prototype using functional databases. For the practical purpose, we use Leadership in Energy and Environmental Design (LEED) as the exemplar standard to demonstrate the integrative process from building information aggregation to final evaluation. We start with a Building Information model, and use Construction Operations Building Information Exchange (COBie) as a bridge to integrate LEED requirements. At present, the process of sustainable building assessment requires information exchange from various building professionals. However, there is no procedure to manage, or use, information pertaining to sustainability. In our research, we translate rules from LEED into computable formulas and develop a prototype application to produce templates for LEED submission.

title	Sustainable Design and Construction: New Approaches Towards Sustainable Manufacturing
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 241-251
summary	Ecological and environmental issues are playing an important and larger role in corporate and manufacturing strategies. For complete creative design process, buildings require both for construction and manufacturing, due to their comparatively long life cycle for maintenance, significant raw material and energy resources. Thinking in terms of product life cycles is one of the challenges facing manufacturers today. “Life Cycle Management” (LCM) considers the product life cycle as a whole and optimizes the interaction of product design, construction, manufacturing and life cycle activities. The goal of this approach is to protect resources and maximize the effectiveness during usage by means of Life Cycle Assessment, Product Data Management, Technical Support and last but not least by Life Cycle Costing. In this paper the environmental consciousness issues pertaining to design, construction, manufacturing and operations management are presented through computer intelligent technologies of this 21century. So, this paper shows the existing approaches of LCM and discusses their visions and further development.

title	Designing Eco Adaptable Residence in a Hot & Humid Climate, in Kolkata, India
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 509-512
summary	The research paper outlines the novel design methodology undertaken to redesign an existing apartment building in Kolkata India. The aim of the research is to significantly improve the design of the individual apartments as well as their spatial arrangement to enhance the indoor comfort level experienced by the inhabitants. The initial in-depth study of the existing design of the apartment building encompasses a short survey of the comfort level experienced by its inhabitants in terms of day lighting, natural ventilation and thermal comfort. The survey revealed the way in which these issues affected the behavioral pattern of the inhabitants in rearranging their spatial needs for the given design conditions. Consequently, the endeavor proposed promised to significantly improve the aforesaid areas of problem & discomfort for the building occupants. At the same time, exploiting contemporary computational simulation tools and digital three-dimensional modeling techniques the project leverages the same to prove the improvements proposed by research data in the form of scientific & mathematical tables and values.

summary	Salient attributes of previously designed projects can be examined to understand how key parameters could inform current design practices. These parameters include gross floor area, number of stories, occupancy, material type, geographic location, seismicity, climatic influences, etc. Two informative analysis tools for intelligent design have been developed which can be used from preliminary planning stages to the final design of individual structures to district-wide developments. These tools can evaluate concurrent influences of these parameters on the built environment. The first is the Environmental Analysis Tool™ (EA Tool). The EA Tool quantifies the estimated equivalent carbon dioxide emissions of structural components. The second analysis tool is Parametric City Modeling (PCM). PCM estimates the usable area of a tower by estimating net floor area. These tools can also be applied to multiple buildings at a district scale to facilitate a new level of design in urban planning efforts. Design information embodied in the physical built environment finds new purpose in the informative prediction of performance at the on-set of digital design. Harvesting and mining data as a natural resource brings new potential to informed design. These concepts and subsequent tools are vital to building sustainable and efficient cities of the future.

summary	Buildings are the world’s largest consumer of energy, accounting for 34% of total use. In the United States residential and commercial buildings are responsible for 72% of electricity use and 40% of CO2 emissions. In order to reduce the impact of buildings on the environment and to utilize freely available environmental resources, building design must be based on site climate conditions, e.g. solar radiation and air temperature. This paper presents a web-based framework that enables the production of user-generated visualizations of weather data. The Open Graphic Evaluative Framework (Open GEF) was developed using the Graphic Evaluative Frameworks (GEF) approach to authoring design-assistant software, which is more appropriate than the now dominant ‘generalized design tool’ approach when supporting design processes that require a high level of calibration to the cyclic and acyclic shifting of environmental resources. Building on previous work that outlined the theoretical underpinnings and basic methodology of the GEF approach, technical specifi cations are presented here for the implementation of a Java driven web-based visualization platform. By enabling more nuanced and customizable views of weather data, the software offers designers an exploratory framework rather than a highly directed tool. Open GEF facilitates design processes more highly calibrated to climatic fl ows that could reduce the overall impact of buildings in the environment.

summary	We outline issues of importance in relation to tectonic design within the architectural profession and the relationship to architectural education in Australia. Twelve years of research and curriculum development at Deakin University is discussed, involving the creation of online resources and case studies, digitally-integrated projects relating to building construction and design studio education. The ethos behind the Construction Primer of engaging students as ‘amateur researchers’ in a way that ensures ‘that student research work is worth more than course assessment’ forms the pedagogical foundation of much of this work. A model of Socially Networked Construction Technology education has been developed that integrates social networks and the Internet to engage students in tectonic design within and outside the classroom through authentic curricula. Through the use of Virtual Galleries, Blogs, YouTube and social networks, a culture of peer learning and sharing has ben developed. Through shared knowledge facilitated through social networks, great potential lies for expanding the synergies between higher order learning and online resource development for design decision support.

summary	Contemporary challenges require inclusively integrated approaches to designing. Constrained by established modes of practice, such integration is impossible without a radical commitment to openness. In response to this need, the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) brought together contributions that engage with open systems in all aspects of architectural and urban design: open with respect to the scale of the design objectives and the context, from a building component within a building system to a neighbourhood or city within its urban and rural context; open with respect to the domains being considered, from planning to sustainable performance of a building or city; open with respect to the collaboration of disciplines and participants, from ad-hoc brainstorming to a rigorous process of consultation and feedback; open with respect to design methods and techniques, from physical modelling to digital prototyping; open with respect to design models and representations being adopted, from a parametric exploration to an ontological delineation considering Building Information Modelling, Built Environment Modelling or City Information Modelling; open with respect to the tools and applications being adopted, despite interoperability issues, from modelling to simulation and assessment; open with respect to the learning approach being adopted, from informal interaction and sharing to formal design education; open with respect to the open source approach being adopted in research and development, in order to gather community involvement and use. The conference was held 15-18 May 2013 at the Department of Architecture, School of Design and Environment, at National University of Singapore.By focusing on the theme of Open Systems, CAADRIA 2013 aimed to explore all these aspects and more, and raise awareness to the need of breaching disciplinary boundaries and reaching creative communities at all levels of expertise, by pooling resources, knowledge and practices, and integrating them through the adoption of open systems.

summary	Behavioural Surfaces is a thesis project in Architecture discussed on December 2010 at the University of Florence. The project explores the surfacespace relationship in which a surface condition, generated from intensive datascapes derived from environmental data, is able to produce spatial differentiation and modulate structural and environmental preformance. Exploiting material self-organization in sea sponges as surfaces that deploy function and performance through curvature modulation and space defi nition, two different surface definition processes were explored to organize the system hierarchy and its performances at two different scales. At the macroscale, the global shape of the building is shaped on the base of isopotential surfaces while at a more detailed level the multi-performance skin system is defi ned upon the triply periodic minimal surfaces (TPMS).

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 96-100
summary	Building Information Modeling (BIM) has been considered as an emerging collaborative strategy since its introduction, meant for AEC industry and heading to benefits in terms of costs and design quality during the whole building lifecycle. BIM approach, originally developed for new projects, can be successfully applied to existing contexts using TLS surveys to collect point clouds and turn them later into smart digital models, taking advantage of new technologies and methods. This paper addresses these themes paying attention to issues and opportunities, considering BIM as a paramount tool to collect and manage data destined to multiple disciplines

summary	Our work is to enable partners of a construction project (building owner, architect, engineer, etc.) to share all the technical data produced and manipulated during the building process, by setting up interfaces for an accessible information system via the internet. Our system would be able to deliver an answer to a user to a particular question asked. The system links databases and allows building partners to access and to manipulate specific information. This paper covers the information structure model based on building construction knowledge and the access to user-relevant information. First, the paper aims to establish the state of the art of the information systems available today in the building construction field. Second, we present the contribution of our research to the description of the building elements (foundations, ramps, stairs, etc.), where information is share by partners who are distant from one another and focused on fields of expertise that are distinct but concurrent. Our system links distributed databases and provides an updated building representation that is being enriched and refined all along the building life cycle. It consists of 3D representations of the building as well as data that are associated with each graphical entity (walls, slabs, beams, etc.).

title	An IFC based design check approach for the optimisation of material efficiency in the built environment
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 275–284
doi	https://doi.org/10.52842/conf.caadria.2012.275
summary	Compared to other industries, the built environment is still the largest and one of the least efficient consumers of resources. Existing measures and procedures for resource recovery and reuse are focused on the demolition phase, when the composition of materials and structures is mostly unknown and hard to be analysed. Therefore, these measures are somewhat inefficient for overall high-rate material recovery. The enhancement of the integrated semantic planning process by the introduction of the IFC unified data standard and BIM technology is a first-time opportunity to track, analyse, document and simulate all relevant players, parameters and processes with an impact on the resource and material efficiency through the entire life cycle of a building in the design phase of a building project. The presented work explores the potential of IFC to serve as a framework for achieving a higher material efficiency in the built environment. A proposed design check approach for the simulation and optimisation of material efficiency in a building over its life cycle is based on a system of key parameters and actions organised in logic trees. The parameters and actions are translated into IFC objects. Additionally required IFC objects and properties are identified and described.

title	Generation and Integration of an Aerodynamic Performance Data Base Within the Concept Design Phase of Tall Buildings
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 87-96
doi	https://doi.org/10.52842/conf.acadia.2012.087
summary	Despite the fact that tall buildings are the most wind affected architectural typology, testing for aerodynamic performance is conducted during the later design phases well after the overall geometry has been developed. In this context, aerodynamic performance studies are limited to evaluating an existing design rather than a systematic performance study of design options driving form generation. Beyond constrains of time and cost of wind tunnel testing, which is still more reliable than Computational Fluid Dynamics (CFD) simulations for wind conditions around buildings, aerodynamic performance criteria lack an immediate interface with parametric design tools. This study details a framework for empirical data collection through wind tunnel testing of building mechatronic models and the expansion of the collected dataset by determining a mathematical interpolating model using an Artificial Neural Network (ANN) algorithm developing an Aerodynamic Performance Data Base (APDB). Frederick Keisler called the interacting of forces CO-REALITY, which he defined as The Science of Relationships. In the same article Keisler proclaims that the Form Follows Function is an outmoded understanding that design must demonstrate continuous variability in response to interactions of competing forces. This topographic space is both constant and fleeting where form is developed through the broadcasting of conflict and divergence as a system seeks balance and where one state of matter is passing by another; a decidedly fluid system. However, in spite of the fact that most of our environment consists of fluids or fluid reactions, instantaneous and geologic, natural and engineered, we have restricted ourselves to approaching the design of buildings and their interactions with the environment through solids, their properties and geometry; flow is considered well after the concept design stage and as validation of form. The research described herein explores alternative relations between the object and the flows around it as an iterative process, moving away from the traditional approach of Form Follows Function to Form Follows Flow.

summary	It is an immutable truth that architecture ultimately exists for humans. Similarly, it is a well-known fact that countless architectural concepts derived and evolved to restrain development, to control building projects and to consider environment are eventually for the benefit of humans. Architecture today, however, is in the hands of a few renowned architects even though it is supposed to refl ect human beings and times and to work for everyone. Is it too much to say that everyone should have a say in the space used by many? In that respect, we have devised DADL System. Anyone, Anytime, Anywhere. The system is an architectural game that stimulates human instincts, has online communities and is easily accessible by Anyone Anytime and Anywhere (3A Rules). DADL System aims to gather users’ ideas and develop architecture, which is essentially enabled by the ‘Advise’ feature. Advise is designed to lead users to think about architecture voluntarily and to guide them to express their ideas. The structure and contents of Advises are very important factors in DADL System. Also, it is divided into two domains, i.e. Web and Mobile, where data exchange is enabled via cloud computing, establishing a base in compliance with the ‘3A’ Rules. The DADL System supports the architecture of everyone without relying on opinions of a few, so as to open the infi nitive potential for communication between architecture and humans, which today’s architecture should advocate.

title	An Ontology-Based Template of User-Actor to Support Agent-Based Simulation in Built Environments
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 171-179
summary	The behavior of a human being in a building, its activities, its interactions with it and with other people are certainly a highly complex phenomenon extremely hard to predict and evaluate. At the same time, the response of a built environment to future users’ needs is one of the key factors of its performance. The Agent-based Modeling paradigm is considered potentially the best way to represent human behavior but, in the building design field, its experiences are limited to representation of partial aspects of human behavior in discrete events. Currently, a more "extended" representation of human behavior able to offer an overview of the human activities related to the building ‘functioning’, is missing,. This lack is due to the complexity of interaction among users and built environment, and to the extensive knowledge, provided by different disciplines, needed to reliably represent it. The proposed research focuses on the construction of a general representation template of user-actor, easy to implement and flexible enough to structure the large amount of data affecting human behavior. The development of the ontology-based template shown in this paper can lead to a user-agent’s entity whose parameters and behavioral rules can encode and represent several ‘aspects’ of real users and their interactions with the other entities (building components, furniture, other people) in a built environment.

summary	Point cloud processing has come a long way in the past years. Advances in computer vision (CV) and machine learning (ML) have enabled its automated recognition and processing. However, few of those developments have made it through to the Architecture, Engineering and Construction (AEC) industry. Here, optimizing those workflows can reduce time spent on early-phase projects, which otherwise could be spent on developing innovative design solutions. Simplifying the processing of building point cloud scans makes it more accessible and therefore, usable for design, planning and decision-making. Furthermore, automated processing can also ensure that point clouds are processed consistently and accurately, reducing the potential for human error. This work is part of a larger effort to optimize early-phase design processes to promote the reuse of vacant buildings. It focuses on technical solutions to automate the reconstruction of point clouds into a digital twin as a simplified solid 3D element model. In this paper, various ML approaches, among others KPConv Thomas et al. (2019), ShapeConv Cao et al. (2021) and Mask-RCNN He et al. (2017), are compared in their ability to apply semantic as well as instance segmentation to point clouds. Further it relies on the S3DIS Armeni et al. (2017), NYU v2 Silberman et al. (2012) and Matterport Ramakrishnan et al. (2021) data sets for training. Here, the authors aim to establish a workflow that reduces the effort for users to process their point clouds and obtain object-based models. The findings of this research show that although pure point cloud-based ML models enable a greater degree of flexibility, they incur a high computational cost. We found, that using RGB-D images for classifications and segmentation simplifies the complexity of the ML model but leads to additional requirements for the data set. These can be mitigated in the initial process of capturing the building or by extracting the depth data from the point cloud.

summary	BIM technology is currently being implemented in the construction industry, though it is still underdeveloped in relation to Facility Management (FC) of extant buildings. There is a strong potential for future development due to the visualization and data analysis capabilities of this technology, amongst others (Becerik-Gerber, Jazizadeh, Li, & Calis, 2012). This research investigates how BIM can be implemented in existing buildings currently in operation. Using a public facility at the University of Bio-Bio as a case study, conclusions are drawn with respect the capabilities of BIM in order to optimize maintenance and operation of existing buildings.
