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	This paper introduces a JAVA based library for parametric modeling through programming. From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depends on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations. We introduce key concepts of the library and show a use of the library within a form finding process driven by irradiance simulation.

summary	The main goal for the architects or planners is to understand a perspective of the user. The foundation of the design process is to create buildings and environments, which will be both innovative and functional for all types of users, including adults and children. While planning the environments for children the particular aspects should be considered. The important questions are: What kind of contact does child have with the city, urban places and buildings? How does the child construct the picture of the city? What kind of urban or architectural spaces contributes to the relation that a child has with the environment? Most of the previous studies concentrating on creation of spaces for children have focused on the perspectives that have adults. According to CAADRIA 2010 paper, the objective of our study was to “learn about” (get to know the) children’s perception of everyday places. The main goal of the project was to define an appropriate tool for the design process. We identified three elements, which were considered to be the most important for child’s identification with environment: home, school, and the journey from home to school. For this purpose, children living in a residential community in Bangkok were surveyed. Contrariwise to the quantitative approach (Neisch, 2010), the concept of Colour – Code Models of space propose a qualitative development of this research – a graphic language which allow to understand the children’s spatial world, the novel way to analyze and present space, useful for educate architects and planners.

title	Simply complex: a case study of construction-driven design using computational methods

summary	This paper explores how fabrication-based criteria can be integrated into design processes through computational methods. Based on the ongoing project of the Library of the Bao’an Cultural Complex in Shenzhen, China (referred as ‘the Library’ in this paper hereafter), this paper discusses the process of the rationalisation of an intuitive architectural form and its subsequent tiling design based on the adaptation to the conventional fabrication techniques of the building façade industry in China. These objectives are followed by the establishment of robust computational systems of automation that provide a concrete basis for the visualisation, the development of envelope details, and the generation of the list of component data for fabrication. This integrative approach is markedly different from a more conventional one, in which computational systems serve as a priori solutions to unconstraint design sketches.

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.

summary	As issues of sustainability gain traction for architects, methodologies for designing, analyzing, and calibrating design solutions have emerged as essential areas of research and development. A number of approaches have been pursued with regard to embedding data into the design process, most fall into one of two approaches to research. The first approach is to mediate environmental impact at the level of applied technology; the second alters building methods and material construction, generating efficient energy use. However, few approaches deal with the crafting of relationships between information and performance on an architectural level. We will examine an approach focused on understanding how crafting relationships between information and design can move architecture towards achieving sustainability. In developing this approach, we created a data-driven design methodology spanning from design inception to construction. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. By contextualizing the solutions generated, we were able design though a set of specific and controlled responses rather than as a singular solution. Information utilization requires a new kind of craft that moves beyond instances into relationships and offers performance sensitive issues in design a focused trajectory. We applied this method to the research and development of a responsive shading structure built in conjunction with a thermal testing lab for two test locations – Austin, Texas (Figure. 1 and 2) and Munich, Germany. The following paper chronicles the design and construction at the Texas site over an academic semester.

summary	This paper outlines a digital design workflow, utilized by the authors, which actively links the geometry platforms being utilized by architects with tools for structural analysis, design, form-finding, and optimization. This workflow leads to an accelerated generation and transfer of information to help guide and inform the design process. The engineering team is thus empowered to augment the architect’s design by ensuring that the design team is conscious of the structural implications of design decisions throughout the design process. A crucial element of this design process has been the dynamic linkage of parametric geometry models with structural analysis and design tools. This reduces random errors in model generation and allows more time for critical analysis evaluation. However, the ability to run a multitude of options in a compressed time frame has led to ever increasing data sets. A key component of this structural engineering workflow has become the visualization and rigorous interpretation of the data generated by the analysis process. The authors have explored visualization techniques to distill the complex analysis results into graphics that are easily discernable by all members of the design team.

title	Parametric Approach to the Bioclimatic Design of a Student Housing Building in Patras, Greece
doi	https://doi.org/10.52842/conf.ecaade.2010.313
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.313-319
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	Increasingly, digital architectural data will become available through information technology. Yet until now, there were no satisfying methods to query this data for architectural purposes. This paper introduces an information retrieval system for parcels that not only allows searching for specific attributes, but also includes properties of shape and context of the building plots. An automatically generated index stores the relevant spatial properties as normalized bitmap images on several layers. When a query is started, only this index has to be queried and not the complete database. The search process can be controlled through a graphical interface that incorporates the user’s sketches. The retrieved parcels are presented as a sorted list of vector drawings including their contained buildings. With the simplified access to these case-studies, quality and efficiency of the architectural design process could be increased.

summary	In this work, we address the challenges in the realization of free-form architecture and complex shapes in general with the technical advantages of ruled surfaces. We propose a geometry processing framework to approximate (rationalize) a given shape by one or multiple strips of ruled surfaces. We discuss techniques to achieve an overall smooth surface and develop a parametric model for the generation of curvature continuous surfaces composed of ruled surface strips. We illustrate the usability of the proposed process at hand of several projects, where the pipeline has been applied to compute NC data for mould production and to rationalize large parts of free-form facades.

summary	This article presents the contribution of our research to the description of the built elements in the site where information is shared by partners who are distant from one another and focused on fields of expertise that are distinct but concurrent. Our work aims to provide an information system that promotes cooperation between the buildings actors, by sharing a unique data model among the partners involved in the building construction processes. It takes into account the technical data needed in the different phases of the supply chain management cycle in the construction field. To answer a cooperative context, our work is based on the fundamental assumption that it is possible to structure a building description following the economist’s view point. During the implementation phase, the different activities on a building site can be described as a model that integrates all the related tasks and includes all the work practices and requirements shared among the partners of the architectural project.

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.

summary	Increasingly, interest in urban design challenges is being tied to research agendas in which data are generated of relevance to design intent. This paper addresses consequent opportunities for those engaged in urban design and discusses opportunities in parametric urban design to move beyond common engagement in description. The paper describes how parametric systems have been used to help students to bridge the gap from conceptual design to propositions and describes models used to develop diagrams of site potential. The paper illustrates the power of diagram in both mapping existing conditions as well as in projecting possible urban futures.

summary	Architects and designers have often used computational design techniques in their design process, even without "computers", from designing spaces which activate at the instant of the solstice sunrise, to creating geometrically complex and structurally innovative cathedrals. Designing with rules and variables can lead to solutions which satisfy the design criteria and may result in interesting and unanticipated models. Computational design is a process of designing and a way of thinking; contemporary tools can promote and enhance this process. Algorithmic and parametric modeling (and thinking) can be powerful processes in design, and particularly in working with complex geometry and addressing project constraints and analytical and data-driven design. This paper describes these methods and provides examples of their use on projects at Skidmore, Owings & Merrill.

title	Generative Design and the Reduction of Presence

summary	Digital design/fabrication is slowly emancipating architectural design from its traditional static/representational role and endowing it instead with a new, generative function. In opposition to the classical isomorphism between drawings and buildings, wherein the second stand as translations of the first, the digital design/fabrication scenario does not strictly fall within a semiotic frame as much as within a quasi biological context, reminiscent of the Aristotelian notion of entelechy. For the digital data does not represent the building as much it actively works to become the building itself. Only upon sending a given file to a machine does the building begin to materialize as an empirical reality, And eventually a habitable space as we empirically know it. And until the digital data actualizes itself, the building qua building is no more than one single, potential possibility among many others. This new universe of digital design/fabrication does not only cause buildings to be produced as quick, precise, multiply-generated objects but also reduces their presence as original entities. Like cars and fashion items, built structures will soon be manufactured as routinely-consumed items that would look original only through the subtle mechanisms of flexibility: frequent alteration of prototype design (Style 2010, Style 2015..) and “perpetual profiling” (mine, yours, hers,..). The generic will necessarily take over the circumstantial. But this truth will be veiled since “customized prototypes” will be produced or altered to individual or personal specifications. This implies that certain “myths” have to be generated to speed up consumption, to stimulate excessive use and to lock people into a continuous system which can generate consumption through a vocabulary of interchangeable, layered and repeatable functions. Samples of “next season’s buildings” will be displayed and disseminated to enforce this strategy of stimulating and channeling desire. A degree of manipulation is involved, and the consumer is flattered into believing that his or her own free assessment of and choice between the options on offer will lead him or her to select the product the advertiser is seeking to sell. From the standpoint of the architect as a maker, the rising upsurge of digital design and fabrication could leave us mourning the loss of what has been a personal stomping ground, namely the intensity of the directly lived experiences of design and building. The direct, sensuous contact with drawings, models and materials is now being lost to a (digital) realm whose attributes refer to physical reality only remotely. Unlike (analogue) drawings and buildings, digital manipulations and prototypes do not exercise themselves in a real space, and are not subjected in the most rigorous way to spatial information. They denote in this sense a loss of immediacy and a withering of corporal thought. This flexible production of space and the consequent loss of immediate experience from the part of the designer will be analyzed within a theoretical framework underpinned mainly by the works of Walter Benjamin. Samples of digitally-produced objects will be used to illustrate this argument.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary	In intelligent epoch, automatic parameter design systems reduce the requirements of the skills needed to create objects. The creator only needs to select the most perceptual primitive form to automatically generate the data system that iterates to the most efficient solution. In this paper, a method of combining performance driven optimization with parametric design is proposed. The iterative evolution is under the control of performance loop and fabrication loop, which makes all the data provided by parametric design in a practical project available for exploring structural analysis and digital prefabrication. Related to the case of surface steel structure, parametric optimization is not limited to a set of shape types or design problems, it would be based on the generality and built-in characteristics of parametric modelling environment in the most convenient and flexible way. (Rolvink et al. 2010)And the given parameters would be fed back on geometric structure, performance indicators, and design variables, so that designers can easily and effectively coordinate and try different solutions. The system transforms the generated data into machine language so that the process including design, analysis, manufacturing, and construction can maintain the orthogonal persistence of the data.

title	Acoustic Performance as a Design Driver: Sound Simulation and Parametric Modeling using SmartGeometry
source	International Journal of Architectural Computing vol. 8 - no. 3, pp. 337-358
summary	Acoustic performance is an inevitable part of architectural design. Our sonic experience is modified by the geometry and material choices of the designer. Acoustic performance must be understood both on the level of material performance and also at the level of the entire composition. With new parametric and scripting tools performance driven design is possible. Parametric design and scripting tools can be used to explore not only singular objectives, but gradient conditions. Acoustic performance is often thought of in terms of singular performance criteria. This research suggested acoustic design can be understood in terms of gradients and multiple performance parameters. Simulation and modeling techniques for computational acoustic prediction now allow architects to more fully engage with the phenomenon of sound and digital models can be studied to produce data, visualizations, animations, and auralizations of acoustic performance. SmartGeometry has promoted design methods and educational potentials of a performance-driven approach to architectural design through parametric modeling and scripting. The SmartGeometry workshops have provided links between engineering and architecture, analysis and design; they have provided parametric and scripting tools that can provide both a common platform, links between platforms, but importantly an intellectual platform where these ideas can mix. These workshops and conferences have inspired two projects that both used acoustic performance as a design driver. The Smithsonian Institution Courtyard Enclosure and the Manufacturing Parametric Acoustic Surfaces (MPAS) installation at SmartGeometry 2010 are presented as examples of projects that used sound simulation parametric modeling to create acoustically performance driven architecture.

title	Integrating Sound Scattering Measurements in the Design of Complex Architectural Surfaces: Informing a parametric design strategy with acoustic measurements from rapid prototype scale models
doi	https://doi.org/10.52842/conf.ecaade.2010.481
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.481-491
summary	Digital tools present the opportunity for incorporating performance analysis into the architectural design process. Acoustic performance is an important criterion for architectural design. There is much known about sound absorption but little about sound scattering, even though scattering is recognized to be one of the most important factors in predicting the acoustic performance of architectural spaces. This paper proposes a workflow for the design of complex architectural surfaces and the prediction of their sound scattering properties. This workflow includes the development of computational design tools, geometry generation, fabrication of test surfaces, measurement of acoustic performance, the incorporation of this data into the generative tool. The Hexagon Wall is included and discussed as an illustrative design study.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.

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.
