title	Performative Building Skin Systems: A Morphogenomic Approach Towards Developing Real-Time Adaptive Building Skin Systems
source	International Journal of Architectural Computing vol. 7 - no. 4, 643-676
summary	Morphogenomics, a relatively new research area, involves understanding the role played by information regulation in the emergence of diverse natural and artificially generated morphologies. Performative building skin systems as a bottom-up parametric formation of context aware interdependent, ubiquitously communicating components leading to the development of continually performative systems is one of the multi-scalar derivations of the aforementioned Morphogenomic understanding. The agenda of adaptations for these building skins specifically corresponds to three domains of adaptation: structural, behavioral and physiological adaptations resulting in kinetic adaptability, energy generation, conservation, transport and usage principles as well as material property based changes per component. The developed skins adapt in real time via operating upon ubiquitous communication and data-regulation protocols for sensing and processing contextual information. Computational processes and information technology based tools and techniques such as parametric design, real-time simulation using game design software, environmental information mapping, sensing and actuating systems coupled with inbuilt control systems as well as manufacturing physical models in collaboration with praxis form a vital part of these skin systems. These experiments and analysis based on developing intrinsic inter-dependencies between contextual data, structure and material logistics thus lay the foundation for a new era of continually performing, self powering, real-time adaptive intelligent building skin systems.

title	Architect Friendly: A Comparison of Ten Different Building Performance Simulation Tools
source	IBPSA
summary	Performance Simulation tools BPS is available internationally. The users of those tools are mainly researchers, physicists and experts who value empirical validation, analytical verification and calibration of uncertainty as defined by e.g. BESTEST. However, literature and comparative surveys indicate that most architects who use BPS tools in design practice are much more concerned with the (1) Usability and Information Management (UIM) of interface and (2) the Integration of Intelligent design Knowledge-Base (IIKB). Those two issues are the main factors for identifying a building simulation program as “Architect Friendly”. Now, with the advancement of BPS tools and the recent announcements of direct links between BIM or non-BIM modeling tools and BPS tools it is important to compare the existing programs. Based on an online survey, this paper presents the results of comparing ten major BPS tools. The following programs are compared: ECOTECT, HEED, Energy 10, Design Builder, eQUEST, DOE-2, Green Building Studio, IES VE, Energy Plus and Energy Plus-SketchUp Plugin (OpenStudio). With 249 valid responses, the survey ranked the tools in three classes and revealed that architects seek the IIKB above the UIM of the interface. Finally, the paper summarizes the key findings and underlines the major requirements for future improvement and development of BPS tools, mainly from an architectural perspective.

title	Adaptation as a Framework for Reconsidering High-Performance Residential Design: A Case Study
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 109-118
doi	https://doi.org/10.52842/conf.acadia.2013.109
summary	This paper outlines an approach to adaptive residential design explored through recent research and an executed prototype, the North House project (2007-2009), undertaken through an interdisciplinary collaboration of researchers and students from the University of Waterloo, Ryerson University and Simon Fraser University in concert with professional and industry partners. This project aimed to develop a framework for the delivery of adaptive detached residential buildings capable of net-zero energy performance in the temperate climate zone, or the near north. Within this project, the term “adaptive” is developed across several tracts of conceptualization and execution including site and climatically derived models for building material composition and envelope ratios, environmentally-responsive kinetic envelope components, intelligent HVAC controls and interactive interface design aimed at producing co-evolutionary behaviors between building systems and inhabitants. A provisional definition of adaptive architecture is outlined to address this range of considerations that calls into question the stable image of domestic architecture and its relationship to energy and contemporary assumptions regarding sustainable design. This paper also outlines computational approaches to design optimization, distributed building systems integration and the human-controls interfaces applicable to the home’s ecology of physical and information technologies.

summary	The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

title	Multi-touch - the future of design interaction
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. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

summary	The research focuses on the performative capacities of a pneumatic material system in regards to the specific environmental conditions. The use of Adaptation as a mechanism to modulate environmental performance was the main focus of the design process and research. The location of the sun during the day acts as a trigger to adapt the system, allowing the system to passively augment the environmental conditions. A new form-finding method that combines digital and material processes has been the main method by which the experiments were undertaken. This approach necessitates a dramatic shift in the architectural design, from producing static to environmentally responsive objects. It requires a shift in thinking from buildings as static and non-active systems to material system existing over time within specific environments capable of complex environmental performances.

summary	We present a student design class, in which experimental full-scale parametric objects are planned and built. The class explores the possibilities of digital production chains in which CAAM techniques driven by parametric modeling can expand the range of possibilities for designing and producing architecture. We show how those possibilities and techniques can be integrated into architectural education in facilitating a transition from digital design to actual object. The didactic challenge represents teaching a methodological approach towards parameter-based design, its transfer into a software program and the choice of construction and production method.

summary	Building Information Modeling may have obvious implications in the process of architectural design and construction at the present stage of technological development. However, BIM has rarely been really assessed and its benefits are often described in generic terms. In this paper we describe an experiment in which such benefits are identified from a comparison between two design processes of the same airport building, one run in a conventional way and the other in a BIM-based approach. The practical advantages of BIM to airport design were remarkable.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
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	A Multi-dimensional Exploration of Urban Attributes by Data Mining
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. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title	Cognition Model in Conceptual Designing
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 771-780
doi	https://doi.org/10.52842/conf.caadria.2009.771
summary	Both design researchers and cognitive scientists have developed various process models to study human creative behaviour in design. The models developed are often based on observations of design processes and analysis of design protocols. This research paper reports the-stateof- the-art in the area of cognition models that present design activities in conceptual designing. The research paper investigates the approaches of these cognition models. A new approach of a cognition activity model in conceptual designing is proposed. The new approach used in the introduced model takes into the account factors and activities that are related to the external environment of design (design medium). The external environment has an important role in the cognition activities and the evaluation process in a way that can hardly be ignored or neglected. The presented model of cognition activities in conceptual designing highlights two main factors employed in all the iteration loops of the model, namely: media use and representation. Case studies of architecture students’ designs have been analyzed. The analysis of these case studies helped in forming the proposed model. Various results have been concluded and reported.

summary	Today, 98% of megaprojects face cost overruns or delays. The average cost increase is 80% and the average slippage is 20 months behind schedule (McKinsey 2015). It is becoming increasingly challenging to efficiently support the scale, complexity and ambition of these projects. Simultaneously, project data is being captured at growing rates. We continue to capture more data on a project than ever before. Total data captured back in 2009 in the construction industry reached over 51 petabytes, or 51 million gigabytes (Mckinsey 2016). It is becoming increasingly necessary to develop new ways to leverage our project data to better manage the complexity on our projects and allow the many stakeholders to make better more informed decisions. This paper focuses on utilizing advances in data mining, data analytics and data visualization as means to extract project information from massive datasets in a timely fashion to assist in making key informed decisions for project delivery. As part of this paper, we present an innovative new use of these technologies as applied to a large-scale infrastructural megaproject, to deliver a set of over 4,000 construction documents in a six-month period that has the potential to dramatically transform our industry and the way we deliver projects in the future. This paper describes a framework used to measure production performance as part of any project’s set of project controls for accelerated project delivery.

summary	We present a physics-based generative design approach to interactive form-finding. While form as a product of dynamic simulation has been explored previously, individual projects have been developed as singleton solutions. By identifying categories of computational characteristics, we present a novel unified model that generalizes existing simulations through a constraint-based approach. The potential of interactive form finding simulation is explored through exemplary studies: a conceptual approach to a fixed form that acts as a visualization of interacting forces, and a constraint-based model of the fabrication logic for a panelization system are examined. Implications of constraint-based simulation on future directions are discussed.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

summary	For sustainable building design, computational tools, mostly in the form of simulations, are employed to determine loads and to predict systems performance typically in terms of energy use. Currently, sustainability, in the building domain, is judged by a rating system. Design choices are validated, by measuring against one. The objective of the framework is to provide a general approach to processing the informational needs of any rating system, by identifying, categorizing and organizing relevant data requirements. Aspects of sustainability that designers deal with intuitively will have a structured guideline and gauge as one selects a rating system of choice.

title	Enhancing synergies between computer science and urban disciplines: Semi-automated applications for tangible user interfaces, a case study
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 314-327
summary	This paper explores an interdisciplinary design approach for coupling semi-automated applications with tangible user interfaces. It describes communication methods based on parameters and diagrams, between computer scientists and urban, architectural professionals and the matching abilities to give meaning to the various parts and elements of the system. By means of the development of two rule based applications it exploits different degrees of automation and kinds of feedback possibilities and its impact on discourse and decision making. It discusses design methods for interactive urban planning applications, which integrate the different requirements and benefits from both disciplines.

summary	Process/product complexity is at present an unavoidable component of present building design approach that affects building product’s quality. To overcome this problem, effective collaboration is required among all the actors involved in the design process. Data and information exchange is not sufficient to guarantee mutual understanding; to support effective collaboration among actors; it is required a proper knowledge formalization and management. This paper reports on an innovative structure for knowledge modeling in cross-disciplinary building design, that has been formalized in a general template. The proposed Knowledge Model has been, at present, implemented by means of available ontology editors and is going to be used into teaching courses to check its efficiency in collaborative building design classes.

summary	This article presents an application of Augmented Reality technology for interior design. Plus, an Educational Interior Design Project is reviewed. Along with the dramatic progress of digital technology, virtual information techniques are also required for architectural projects. Thus, the new technology of Augmented Reality offers many advantages for digital design and construction fields. AR is also being considered as a new design approach for interior design. In an AR environment, virtual furniture can be displayed and modified in real-time on the screen, allowing the user to have an interactive experience with the virtual furniture in a real-world environment. Finally, this study proposes a new method for applying AR technology to interior design work, where a user can view virtual furniture and communicate with 3D virtual furniture data using a dynamic and flexible user interface. Plus, all the properties of the virtual furniture can be adjusted using occlusion based interaction methods for a Tangible Augmented Reality.

title	Building design as individual compromise between qualities and costs: A general approach for automated building generation under permanent cost and quality control
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 458-471
summary	We introduce an evolutionary design approach for the automatic arrangement of a predefined space program on a given site. The design goal is to distribute floor spaces while ensuring the essential building performance and usage. The presented evolutionary strategy is applied to acquire optimal design solutions considering both environmental conditions and inner organization under diversified fitness functions. The evaluation process consists of the direct analysis of the spatial network and the physical factors in an adequate accuracy. The method provides a fast generation of qualified volumetric studies. The resulting buildings become a manifested compromise between qualities and cost.

summary	Within computational environmental design (CED), different Machine Learning (ML) models are gaining ground. They aim for time efficiency by automating simulation and speeding up environmental performance feedback. This study suggests an approach that enhances not the optimization but the generative aspect of environmentally driven ML processes in architectural design. We follow Stan Allen's (2009) idea of 'field conditions' as a bottom-up phenomenon according to which form and space emerge from local invisible and dynamic connections. By employing parametric modeling, environmental analysis data, and conditional Generative Adversarial Networks [cGAN] we introduce a generative approach in design that reverses the typical design process of going from formal interpretation to analysis and encourages the emergence of spatial configurations with embedded environmental intelligence. We call it Intensive-driven Environmental Design Computation [IEDC], and we employ it in a case study on a residential building typology encountered in the Mediterranean. The paper describes the process, emphasizing dataset preparation as the stage where the logic of field conditions is established. The proposed research differentiates from cGAN models that offer automatic environmental performance predictions to one that spatial predictions stem from dynamic fields.
