summary	The research project, tetrahedron cloud, explores agent-based stochastic behavior as a design tool. It investigates the possibilities for producing volumetric tetrahedral meshes based on the interactions of individual stochastic agents. The research situates itself at the intersection of the visual arts, the physical sciences, and computer science. The basic interest in stochastics comes from the visual arts; the growth simulation approach is borrowed from the natural sciences; and the use of a tetrahedral mesh within C++ comes from computer science. But more generally, the project focuses on architecture’s ongoing engagement with stochastic systems. By embedding extremely specific tendencies within an agent’s behavior, while also allowing for stochastic variation, we can create larger systems that are both in and out of our “control”. This sidesteps the typical limitations of many computational geometry and parametric methods, where there is often an overly deterministic relationship between the input and output of a given system. Such a shift from optimization to behavior inevitably brings up troubling questions of style. Abandoning the search for a “best” solution, or even the articulation of the criteria for such a task, re-opens computational architecture at its deepest levels as a site for design speculation.

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.

title	Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

summary	Architectural competitions have been traditionally used to select best design practices. The basis of assessment for competitions has typically involved non-technical concepts of quality, subjective and emotional appreciations of experiences, and inseparable accord of formal, functional, aesthetic and contextual values (Rönn, 2011), rather than clear-cut objective and precisely measured values as in the engineering domain (Nashed, 2005; Nelson, 2006). Criteria for judgment usually focus on design parti and clarity of concept, novelty of architectural approach, context compliance, spatial organization, functional adaptability, economical solutions, and design flexibility. The assessment process, although presumably comprehensive and involving multiple evaluation techniques and resources, may still overlook important technical issues that may be fundamentally significant to the exclusion or approval of a given entry. This paper introduces a framework for assessing architectural competition entries aided by concepts of building information modeling (BIM).

title	Irregular Vertex Editing and Pattern Design on Mesh
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 278-283
doi	https://doi.org/10.52842/conf.acadia.2011.278
summary	This paper introduces an innovative computational design tool used to edit architectural geometry by addressing the problem of irregular vertices. An irregular vertex is a special kind of vertex which is connected with fewer or greater less or more edges than regular vertices on a mesh object. Irregular vertices create problems with further surface rationalization, as well as structural analysis and constructability of the surface. Geometry created using other tools can also be remeshed upon import. Using the developed tool, the user is able to identify irregular vertices, interactively change the type, and then move or remove these irregular vertices. Additionally, a computational tool to make various design patterns on the mesh after the topology has been edited is also developed. The workflow is illustrated step by step in the pipeline. The advantages and disadvantages of editing mesh topology on architectural geometry design including the limitations are discussed at the end.

title	The Other Digital - What is the Glitch in Architecture?
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 551-559
doi	https://doi.org/10.52842/conf.caadria.2017.551
summary	This paper will discuss and investigate the issues with the concept of 'glitch' in architecture. There are currently two definitions that sit in a symbiotic relationship with each other; Moradi's (2004) and Menkman's (2011). This paper will explore the implications of these two approaches, while investigating the possibility of a third, unique definition (the encoded transform), and what effect they have on the possibility for a 'glitch architecture'. The paper will then focus on the glitches' capacity to be disruptive within the design process. In the context of architecture, it has been previously argued that the inclusion of glitches within a design process can easily create a process that does not 'converge' to a desired design outcome, but instead shifts haphazardly within a set of family resemblances (Austin & Perin 2015). Further to this, it will be revealed that this 'divergent' quality of glitches is due to the encoded nature of architectural production.

title	Last train to trancentral: From infrastructure to ‘info’structure: a case study of embedding digital technology into existing public transport infrastructures
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. 335-344
doi	https://doi.org/10.52842/conf.caadria.2011.335
summary	The research presented in this paper is an investigation into how ubiquitous computing technologies can contribute to improving the quality of existing public transport environments through the integration of responsive technologies. The paper argues that given the significant challenges associated with transport infrastructure expansion including cost, disruption, energy use, and implementation periods augmenting existing transport environments offers alternate measures to manage demand and improve the user experience. The paper proposes improving transport environments by integrating smart, or responsive, digital information into the existing physical fabric in a coherent architectural and spatial context. This approach offers an opportunity to shift away from the static nature of public transport infrastructure to the dynamic notion of public transport ‘info’structure. The research uses an architecture graduate studio as a foundation to investigate the objectives. The contribution of this paper is an investigation of ways in which digital technologies and networked communications can transform and augment public transport infrastructure, allowing new forms of intelligent, adaptive, interactive and self-aware architecture to be developed.

summary	This research is related to the urban transformation that Medellín underwent during the 2004-2011 administrations, in which large architectural projects were implemented in the poorest and most violent areas of the city. To inquire about the effectiveness of these interventions, we look at one of the housing projects worthies of different international recognitions, called the Housing Consolidation of the Quebrada Juan Bobo. Characterized by generating Social Interest Housing (Vivienda de Interés Social-VIS in Spanish) in the creek’s basin, this project benefited 1,240 people who were relocated within the same neighborhood, including some on the same space next to the creek, where their old home was built.

title	Aviva Stadium: A case study in integrated parametric design
source	International Journal of Architectural Computing vol. 9 - no. 2, 187-204
summary	The nature of large complex buildings requires specialized skills across a multi-disciplinary team and high levels of collaboration and communication. By taking a parametric approach to design and construction, high quality results can be delivered on budget on time. This type of approach facilitates the opportunity for design teams to work in an iterative manner.A parametric model reduces the time associated with complex design changes while providing a centralized method for coordinating communication. In this paper the recently completed Aviva Stadium is used to illustrate the ways in which these benefits manifest themselves on built work.The authors identify the moments in the design and construction process that truly justify the effort in implementing a parametric approach. By approaching design in this way a “design conversation” can take place between parties involved, resulting in a better building.

title	Computational method for mapping quality of architectural space
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. 473-482
doi	https://doi.org/10.52842/conf.caadria.2011.473
summary	The key aim of this paper is to develop a computational method for mapping architectural space used for visual openness analysis. We suggest that the result will offer possibilities for quantitative design analysis particularly on spatial quality influenced by architectural elements. The proposed method consists of two stages: determination of subdivided enclosed spaces and measuring quality using visual openness parameters on each subdivided enclosed space. We advise new approach to determine subdivided enclosed spaces on architectural plan by determining two factors: bounded space and circulation space. Computational procedures applied to analyse architectural plan and then determine map of subdivided enclosed space by analysing relationship of these two factors. The concept underlying this method is that architectural space is composed of subdivided enclosed spaces, which each of them have distinct physical properties and therefore become possible to develop mapping of evaluation regarding the quality of architectural space. Our finding on orthogonal architectural plan provides ranking index of subdivided enclosed spaces that could help for analysing spatial quality of architectural space.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
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. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

title	Spatial Experience in Real & Virtual Environment as an Urban Design Tool
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 59-64
summary	The innovations of information technologies and the new possibilities of multimedia exploitation in the realm of architectural design and education are supporting the development of image communication methods on the basis of interactivity. The creative process of searching and decision-making in the urban design studio of our Faculty is supported by spatial modeling methods. The draft is sketched in modeling material on a working model. From the didactic point of view, relevant are mainly those phases, in which is possible, in the imaginative way, to support the searching and decision making process with the aim to test, compare and continuously evaluate the fulfillment of the hypothetic intentions of the solution responsibilities. The model becomes an interactive medium of cooperation between teacher and the working group of students. From the view of design crystallization, the dominant phases, in the creative process, are examining, verification, and simulation. The alternatives of material-compositional content and the spatial performance charts of modeled physical structure are verifying and the visual experience of the anticipated urban environment is simulated by the author, but also through the future client’s eyes. The alternation of the composition’s spatial configurations is generally appreciated by the static visual verification in the endoscopic horizon like the architectural spatial studies. The effective method of the progress generates a creative atmosphere for the generative thinking and design. The laboratory simulation of spatial experiences and their evaluation is performed following the perception psychology relations. The simulation of digestion of the new spatial reality intervenes the customer’s identification and guides to subjective approaches towards the quality and complexity of the formed environment. The simulation is performed in motion in order to be able to anticipate the dynamic continuity of subjective spatial imagination. The induced atmosphere will direct the evaluational attitudes of authors on comparison and selection of the successful alternatives. In our fee, we will present the demonstrations of selected static and dynamic notations of image sequences prepared in our laboratory. The presentations have been created in order to analyze, verify and offer imaginative support to creative findings in result of fulfilling the studio design tasks in the educational process. The main one is the design of urban spatial structures. The laboratory methodology is in the first place oriented on the analogue-digital procedures of "endoscope" model simulation. At the same time it also explores and looks for new unconventional forms of visual communication or archiving as imagination support to specialist and laymen participants in creative, valorization and approval processes.

summary	Real estate search system currently supports users’ search for sale and consumption. However, the quality of the search results is unsatisfactory in most cases. This is due to the lack of system capacity to accurately understand and process all-different userpreferences. Therefore, this study aims to solve the said issue by newly constructing real estate information via “Case-based Reasoning” and “Ontology.” We conducted research on the terminology related to real estate search that could be seen in a number of Q&A communities. Based on the work, a hierarchical structure of the concepts was reorganized. In addition, a real estate search system was developed to authenticate its effectiveness while dealing with several exemplary cases.

summary	Throughout the world, global warming has been considered a severe problem, which has led to efforts being made for technical development to reduce greenhouse gases in the building sector. As more attention has been paid to energy consumption by residential housing in the building sector, policies and studies on domestic dwellings tend to focus on quality improvement and energy-efficient housing development rather than quantitative housing supply. Yet, policies and guidelines considering residential energy efficiency are inclined to focus on performance and lack in integrated consideration in connection with design. Hence, it seems necessary to compare and analyze design and energy efficiency and to study correlations between housing design and energy. Lately, BIM technology has been used in buildings domestically and proved reliable in respect of its features that enable overall comparison and prediction of housing design, performance and efficiency. The present study is to use the BIM technology to analyze energy consumption and the standard drawing schemes for rural areas to find ways to improve efficient design in singles housing sector and to suggest how to take advantage of buffer zones and how to improve housing design in favor of energy efficiency.

summary	Scientific output has well-established methods for comparing and scoring the quality and quantity of the work. For artistic output this matter is not settled at all and a subject of much debate. We present a method which has been developed in Czech republic since 2011. This method is used to compare and score the artistic output of all schools of arts in the country (for example, music, performative arts, architecture, literature, sculpture, painting). The system presented in this paper is based on the Saaty-method (also known as Analytic Hierarchy Process). After almost eight years of development and use, the system has proven as a valuable asset to assess in an objective way output between many different forms of artistic works. In 2016 the system was incorporated in the Higher Education Act. In the paper we present a brief history of the development and the principles of AHP applied in the system. In particular, we will focus on the findings in architecture derived from the system. Finally, we will discuss possible implications for architectural education in general.

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. 367-382.
summary	Since 2006, half of the world’s population lives in cities. In the age of climate change, designing for quality environmental living conditions and sustainability is a topical concern. However, on the one hand, designers and city planners operate with their three dimensional city morphological data such as building shapes and volumes, forms and their spacings, and functional attributes and definition signatures. On the other hand, urban climatologists operate with their numbers and equations, quantities and signals, and normals and anomalies. Traditionally the two camps do not meet. It is a challenge to develop design tools that they can work together. Map based information system based on computational geographic information system (GIS) that is properly structured and represented offers a common language, so to speak, for the two professional groups to work together. Urban climatic map is a spatial and graphical tool with information embedded in defined layers that are collated so that planners and urban climatologists can dialogue over design issues. With various planning and meteorological data coded in defined grid resolutions onto the GIS map system, data can be synergized and collated for various understandings. This papers explains the formulation of Hong Kong’s GIS based Urban Climatic Map as an example of how the map works in practice. Using the map, zonal and district based planning decisions can be made by planners and urban climatologists that lead to new designs and policy changes.

summary	In this paper, we will stress the importance of usability as a key quality characteristic for the Computer Aided Architectural Design (CAAD) software prototypes. We claim that usability evaluation practices can assist the integration of human factors and the accommodation of local differences. These practices are not solely limited to interface tests, but they can also provide valuable information on the possible added values of CAAD software prototypes, increase the overall product quality and thus contribute to the sustainable development of the CAAD research field. In this context, we aim to initiate a constructive discussion on this topic by reviewing various usability frameworks and highlighting possible opportunities and challenges of applicable evaluation methods. Consequent to this discussion, we will elaborate on our recent findings relating to the reliability and effectiveness of particular evaluation methods applied to a web-based geographic virtual environment prototype. In conclusion, we will introduce a new “design usability” framework that is suitable for CAAD software development; which suggests a variety of design usability quality characteristics, cost-effective evaluation methods and possible influence factors in the evaluation process.

title	The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary	At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

summary	With digital design and fabrication becoming ever more common in architectural design, the computational geometry topic of discretizing freeform surfaces into flat panels has become a common challenge. At the present, most approaches to the issue of preserving a 2D-tessellation on a freeform surface are focused on optimizing the shape of the structure by approximating geometric “equally-sized” flat patterns. In doing so, these strategies treat the approximation of the desired shape as the primary goal, leaving aside the aesthetical aspect of the paneling, which can be seen as having an ornamental quality. In contrast to these common strategies, the project presented in this paper pursues a more holistic approach that tries to integrate aesthetical as well as structural issues by using more complex as well as more performative patterns for the discretization. In the present paper, we present algorithmic strategies that were designed to integrate from the aesthetics of an exposed timber structure, through analysis of structural loading feedbacks to a detailed level of the physical joint system, as part of the fundamental early design decisions. The consequence of the overall negotiations relies fully on their physical integration through computational design. The present paper discusses both the algorithmic techniques and the joint systems through a series of case studies. At the end of the paper we provide an overview to upcoming tasks including the production of a major structure.

summary	As Hong Kong constructs increasingly high-density, high-rise public housing estates to increase land use efficiency, public in-between spaces are more constrained, which impacts the quality of social relations, movements and daily practices of residents (Shelton et al. 2011; Tang et al. 2019). Current planning practices are focused on the achievement of quantitative performance measures, rather than qualitative design considerations that support residents experiences and community interaction. This paper presents a new methodology that combines urban analysis and generative design for the regeneration of social housing estates, based on the spatial and social qualities of their in-between spaces.
