summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

summary	A new housing complex on the Campus of the University of Patras, Greece, is expected to serve as a test-bed for experimentation with a parametric design process that integrates significant climatic data. To optimize the environmental performance of the proposed housing complex a parametric design algorithm has been developed. The algorithm links the weather data in the area with the site topography and the basic geometric features of the buildings on the site. To explore the interaction of the building features with the prevailing winds in the area and the solar exposure throughout the year various software applications, including computational fluid dynamics (CFD) simulations, have been utilized. The inclusion of wind data in the algorithm renders it particularly effective. The developed parametric process has been useful during the early design phase when studies on various patterns for arranging the buildings on the site were conducted. The parametric process has facilitated the configuration of the typical building block as well.

summary	As technology advances, users get more detached from the way things work and are produced. Users end up being pure consumers and leave their positions as decision makers behind. Before the architecture and buildings processes were industrialized, most practitioners of the so-called vernacular architecture were in fact the dwellers of what they built and they easily met the specific personal needs since they were in total control. Some “architectural theorists have turned to vernacular construction with the conviction that such buildings and settlements express the interconnectedness between humans and the landscapes they live in.” (Beesley and Bonnemaison 2008). Considering the present day intense building activity, such relationship of dweller and architecture seems not possible excepting a very few examples to later referred to. This paper will instead focus on the possibility of the non-architect users of architectures as decision makers in order to reach designs that meet the requirements of their addressees.

summary	Digital Heritage has gained popularity recently as means of dynamically representing and reconstructing historic buildings and cityscapes. Simultaneously this new medium of visualization affords another approach to examine human-virtual environment interaction and offers possibilities of exploiting virtual environments as educational tools. At Zayed University, a federal university primarily for women citizens of the United Arab Emirates, we have integrated student-faculty research and documented and reconstructed a number of historical buildings within the curriculum of the Department of Art and Design. We have further collaborated with the animation program at Winston Salem State University in North Carolina, utilizing the motion capture laboratory at the Center of Design Innovation to literally breathe life into these reconstructions. The primary idea is to contribute to the ongoing documentation of the country’s heritage through creating “responsive virtual heritage environments” where the spectator is actively engaged in exploring the digital space and gain certain degrees of control over the course and scheme of the dynamic experience. The process begins by introducing students to utilize the diverse capabilities of CAD and three dimensional computer applications and intertwine the technical skills they acquire to construct virtual computer models of indigenous built environments. The workflow between the different applications is crucial to stimulate students’ problem solving abilities and tame the application tools, specifically when constructing complex objects and structural details. In addition the spatial and temporal specificity different computer applications afford has proven useful in highlighting and analyzing the buildings’ function within the extreme climate of the country and their role in the political-economy, particularly in visualizing the ephemeral qualities of the architecture as they relate to passive cooling and the inter-relationships between built and natural environments. Light and time settings clarify shadow casting and explain the placement and orientation of buildings. Particle simulations demonstrate the harnessing of wind and rain both urban and rural settings. The quantitative data accumulated and charted through CAD and VR programs and geo-browsers can be integrated with qualitative data to create a more holistic analytical framework for understanding the complex nature of past settlement patterns. In addition, the dynamic nature of this integration creates a powerful educational tool. This paper reviews this ongoing research project with examples of reconstructions completed across the country, demonstrating analytical and educational possibilities through the integration of CAD programs with a range of other statistical, geographic, and visualization software.

title	HYGROSCOPIC CLIMATIC MODULATED BOUNDARIES: A Strategy for Differentiated Performance Using a Natural Circulative and Energy Captive Building Envelope in Hot and Moisture Rich Laden Air Environments
source	Perkins+Will Research Journal, Vol 02.01, 41-53
summary	The operation and construction of buildings account for almost half of the energy use in the United States. To meet global climate change targets, energy consumption of buildings in the long term must be reduced as well as carbon dioxide emissions. This article explores a theoretical building envelope that generates energy and produces water by drawing water vapor out of the air to deliver new sources of water; it lowers indoor humidity in hot and humid climates. The design in this model considers materiality, surface area and environmental conditions to influence build- ing form. The case in this article considers materials and systems application in the design of the building envelope. The hygroscopic building envelope design strategically senses varying conditions of concentration and density of moisture laden air to provide visual indications of its performance. It is a building skin that emulates biological processes by creating pressure differences and transferring energy in various forms.

title	Augmented Reality-Based Education and Fire Protection for Traditional Korean Buildings
source	International Journal of Architectural Computing vol. 8 - no. 1, 75-91
summary	This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields. While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

summary	The first component of a building implemented in a virtual prototype concerning the management of a building is a lighting system. It was applied in a study case. The interactive application allows the examination of the physical model, visualizing, for each element modeled in 3D and linked to a database, the corresponding technical information concerned with the use of the material, calculated for different points in time during their life. The control of a lamp stock, the constant updating of lifetime information and the planning of periodical local inspections are attended on the prototype. This is an important mean of cooperation between collaborators involved in the building management.

summary	Effective strategies for the design of efficient and environmentally sensitive buildings require a close collaboration between architects and engineers in the design of the building shell and environmental control systems at the outset of projects. However, it is often not practical for engineers to be involved early on in the design process. It is therefore essential that architects be able to perform preliminary energy analyses to evaluate their proposed designs prior to the major building characteristics becoming fixed. Subsequently, a need exists for a simplified energy design tool for architects. This paper discusses the limitations of existing analysis software in supporting early design explorations and proposes a framework for the development of a tool that provides decision support by permitting architects to quickly assess the performance of design alternatives.

summary	This paper reports on the computer process to be used in an ongoing research to investigate the effect of architectural parameters of tall buildings on the incorporation of wind turbines. The process combines a generative modeling tool (Grasshopper) and a performance based CFD tool (Virtualwind). The process is demonstrated on three typical tall building plan configurations. The wind speed was simulated at certain locations to demonstrate the ability of tall buildings to enhance the wind speed and thus maximize the energy produced by wind turbines located between twin towers. The process to predict wind power production is lastly listed.

summary	Spurring new and innovative building design will be critical to the urban energy and economic future of the nation. The operation of completed buildings account for 48% of the nation’s annual greenhouse gas emissions, and 76% of all electricity generated by U.S. power plants goes to supply the building sector. Therefore developing and applying new and innovative sustainable building design will have a measurable impact on the environment. Recent studies show sustainable building design is closely linked to system integration, where various components of a building work in confluence to produce synergetic benefits. As a result, a critical component of sustainable design involves a clear understanding of building systems operation, interaction, and the selection parameters. A consideration of suitable building systems, gauging their interaction, and proposing well integrated systems can lead to producing efficient models of sustainable buildings with minimal impact on the environment. The following paper outlines the progress on a project entitled “Building Literacy: the Integration of Building Technology and Design in Architectural Education.” The project develops a digital tool for teaching/learning architectural technology from an integrated systems perspective. The project attempts to immerse students in a simulated environment that is based on the real life practice of architecture. The project accomplishes this by harnessing the capabilities of simulation and dynamic modeling programs, as well as the state of art graphic media, to create compelling and rewarding reasons for students’ engagement in the lear ning process. The project involves a multidisciplinary team of faculty from Florida International University, University at Buffalo the State University of New York, and Iowa State University and is funded by the US Department of Education for the period of 2007-2011.

title	Automated 3D Reconstruction of Interiors from Point Clouds
source	International Journal of Architectural Computing vol. 8 - no. 1, 55-73
summary	We present a new technique for the fully automated 3D modelling of indoor environments from a point cloud. The point cloud is acquired with several scans and is afterwards processed in order to segment planar structures, which have a noticeable architectural meaning (floor, ceiling and walls) in the interior. The basic approach to data segmentation is plane sweeping based on a hypothesis-and-test strategy. From the segmentation results, the ground plan is created through cell decomposition by trimming the two-dimensional ground space using half-space primitives. An extension in height of the ground contours makes the generation of the 3D model possible. The so-reconstructed indoor model is saved in CAD format for analysis and further applications or, simply, as a record of the interior geometry.

summary	Data is ubiquitous in our cities. However, designing a knowledge network about our cities is an arduous task, given that data sensed cannot be used directly, human significance must be added. Adding human significance can be achieved via an automated “expert system (ES)” in which domain expert knowledge are stored in a knowledge-based repository. The domain expert knowledge is matched with the corresponding data to derive specific inference which can aid decision making for urban stakeholders.This requires amalgamation of various interdisciplinary techniques. This paper presents a survey of existing technologies in order to investigate the emerging issues surrounding the design of a live knowledge network for sustainable urban living. The maps and models of the existing infrastructure of our cities that include a wealth of information such as topography, layout, zoning, land use, transportation networks, public facilities, and resource network grids need to be integrated with real-time spatiotemporal information about the city. Public data in forms of archives and data streams as well as online data from the social network and the Web can be analyzed using data mining techniques. The domain experts need to interpret the results of data mining into knowledge that will augment the existing knowledge base and models of our cities. In addition to the analysis of archived and streamed data sources from the built environment, the emerging state-of-the-art Web 2.0 and mobile technologies are presented as the potential techniques to crowddesign a live urban knowledge network. Data modeling, data mining, crowdsourcing, and social intervention techniques are reviewed in this paper with examples from the related work and our own experiments.

summary	This work documents the implications of using physical media to teach digital design concepts, techniques, values and approaches. With the pedagogy and work of a seminar and studio across two Universities as test cases, this research seeks to prove that a parametric and algorithmic approach to architecture is most fruitfully understood as the connection between logic, mathematics and aesthetics. Students trace the indirect relationships between process and product so as to enable the application of these connections in a non-linear, exploratory and goal-flexible design process. The first phase of student work involves the creation of an image, constructed with ink or graphite on paper, that embodies a parametric aesthetic. Students are tasked articulating and performing operations, such as dividing a curve, packing shapes, and conditional transformations. Subsequently, students fabricate a surface-conscious model with modules that have the capacity to vary based on their grid parameter, using historically rooted techniques such as weaving, perforating, layering and tessellation. Digital fabrication and parametric modeling is then introduced, not as a means to a predefined end, but as another medium, capable of participating with manual techniques. As an example, a fabricated paper-based installation is generated with parametrically generating a cut-sheet, partially blind to its assembled manifestation. The hypothesis of this research is tested in more comprehensive projects that follow as environmental forces are resolved through dynamic and ambiguous visual and spatial conditions.

title	Assessing innovation in hybrid designs using shape grammars
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 545-554

summary	Al-kazzaz et al (2010) described hybrid adaption technique to generate innovative designs from heterogeneous precedents using shape grammars. An evaluation of the degree of innovation in the hybrid designs gave feedback to grammar users before and after applying a rule. Innovation was assessed using variables derived from the internal structure of the grammar such as: the number of antecedents in the corpus having the same rule; the number of rules in a subclass rule set having the same geometry; etc. However, the validity of the innovation assessment was unclear and the use of the feedback measures was not demonstrated. Accordingly, this study aims to verify the credibility of the innovation measures and to identify the independent variables that a user can control to achieve a significant impact on each innovation measure as a dependent variable.

summary	This paper proposes the use of parametric design software, which is generally used for real-time analysis and evaluation of architectural design variants, to create a new production immanent design tool for robot milling. Robotic constraints are integrated in the data flow of the parametric model for calculating, visualizing and simulating robot milling toolpaths. As a result of the design process, a physical model together with a milling robot control data file is generated.

title	Between Thermal Efficiency and Formal Expression: Tropism as a Method for Layering Control in Generative Design
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 244-247
summary	The definition of architectonic features often requires negotiation between diverse classes of design conditions merging in particular elements. The use of encompassing concepts opens possible approaches for layering control between these assorted factors. This study presents a method for the implementation of tropism as a conceptual gathering procedure in social housing windows definition, aiming to enhance the relationship between building and context in terms of spatial comfort and formal expression.

title	Humanising ICT to a Smarter Dwelling Environment
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 221-230
summary	Dwelling environment is not intelligent if it does not include the concept of home. The emergence of ICT allowed new functions as well as new ways of performing the traditional ones. The need to be online does not remove the need of privacy and to print the site. New ways of living require rethinking dwelling typology to flexibility. Intelligent environments will appear to elevate the sense of home, where security, autonomy, independence, comfort and interaction will be crucial to promote a more qualified life. Technological solutions can be driven in different directions: energy efficiency; lightening and temperature control, video surveillance, access control, etc., assistive environments; entertainment solutions like home theater and professional ones; all have in common to conceive the environment that matches user’s expectancies, where human interaction and social participation emerge as crucial requirements.

title	'GHShot': a collaborative and distributed visual version control for Grasshopper parametric programming
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 35-44

summary	When working with parametric models, architects typically focus on using rather structuring them (Woodbury, 2010). As a result, increasing design complexity typically means a convoluted parametric model, amplifying known problems: 'hard to understand, modify, share and reuse' (Smith 2007; Davis 2011). This practice is in contrast with conventional software-programming where programmers are known to meticulously document and structure their code with versioning tool. In this paper, we argue that versioning tools could help to manage parametric modelling complexity, as it has been showing with software counterparts. Four key features of version control: committing, differentiating, branching, and merging, and how they could be implemented in a parametric design practice are discussed. Initial user test sessions with 5 student designers using GHShot Grasshopper version control plugin (Cristie and Joyce 2018, 2017) revealed that the plugin is useful to record and overview design progression, share model, and provide a fallback mechanism.
