summary	Do the thinking processes which generate architectural design contrast so sharply with the thinking processes generated by the computer that a question like this is asked ? Or is it because computer- integrated education is still missing from the agenda for architectural education that a question like this is rarely asked?

title	Towards BIM-based Parametric Building Energy Performance Optimization
doi	https://doi.org/10.52842/conf.acadia.2013.101
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. 101-108
summary	The demand for sustainable buildings with minimal environmental impact and efficient energy use is increasing. The most effective design decisions for sustainable design can be made in the early design phases, but appropriate tools to explore design alternatives and understand their impacts on building energy performance are not available at this stage of the project. The integration of Building Information Modeling (BIM) and parametric modeling is the new trend of building modeling, which can greatly benefit sustainable building design. This research introduces an innovative tool to facilitate integrated parametric BIM and to enhance its applications towards creative, sustainable building design through simulation and optimization. The created tool, Revit2GBSOpt, integrates parametric BIM and building energy performance simulation and enables designers to generate alternative options in BIM to explore the energy performance simulation results automatically. Finding the optimized solution, the BIM model will be updated.

title	Interdisciplinary Intersections: New roles for digital technologies and landscape architecture in the design of large scale infrastructures
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 123-135
summary	The introduction of BIM is assumed to introduce higher degrees of collaboration and efficiencies within design and construction practices. The potentials of this collaboration tend to focus on architecture, engineering and construction (AEC). Landscape architecture is rarely discussed within this model, technically nor conceptual. This paper explores the potentials of landscape architecture’s contribution to this new model of digitally driven collaboration. Drawing on interviews with the architects, landscape architects and engineers we explore the role of landscape architecture in the conceptualization, design and construction of the Victorian Desalination Plant, a highly political project located on an ecological sensitive coastal site. This paper highlights the centrality of the landscape digital model in mediating the critical intersection between the design parameters, physical attributes of the site, performative qualities of the design and the disciplines of architecture, landscape and engineering. This model also formed the dominant method for communicating the complex project to stake holders and clients. Significantly, this model was not developed into a BIM model, with content instead integrated into the architectural and engineering models. This research highlights one of the major difficulties in conceptualizing the positioning of landscape architecture within a BIM driven collaborative process. To operate effectively, landscape architecture must engage across the multiple scales and disciplinary intersections. Consequently, landscape architects must understand the digital and spatial languages of architecture and engineering, and conceptualise where their contribution lies within ‘paperless’ design and construction processes. This outcome differs significantly from current debates within landscape architecture which instead focus on the identification of ‘the’ specialist BIM software most appropriate to the discipline, as distinct from understanding BIM as a collaborative process.

title	Symmetry in Running
source	Science. March, 1986. vol. 231: pp. 1292-1294 : ill. includes bibliography
summary	Symmetry plays a key role in simplifying the control of legged robots and in giving them the ability to run and balance. The symmetries studied describe motion of the body and legs in terms of even and odd functions of time. A legged system running with these symmetries travels with a fixed forward speed and a stable upright posture. The symmetries used for controlling legged robots may help in elucidating the legged behavior of animals. Measurements of running in the cat and human show that the feet and body sometimes move as predicted by the even and odd symmetry functions

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 109-112
summary	3D digital models allow the visualization of both the historical and morphological evolution of a building - combined with its environment and transformations - as well as, its survey, record and pre-view of the impact of future interventions. Furthermore, the employment of digital technology offers a great advance in the field of cultural good’s documentation by including not only tangible issues but also iconographic elements, materials information and constructive pathology survey, to mention a few. This kind of models had become an open documentary system, and they should be considered essential in every architectural heritage conservation´s project.

title	Testing 3D Building Modelling Framework In Building Renovation
doi	https://doi.org/10.52842/conf.ecaade.2006.268
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 268-275
summary	The paper describes a process where digital measuring survey data is transferred into 3D building model to be used as a foundation for renovation design. The process and method is tested in a case study of an office building of 8 floors. Measuring survey data is more often documented to 2D plan drawings, whereas 3D-modelling was more preferable in the case project. The final aim of the case project is to further test building product model or building information model (BIM) based design methods in building renovation. Product modelling is one emerging framework to manage building related information in contemporary design & construction. Model based methods are more commonly used in new buildings, whereas renovation is usually done with more traditional techniques. Case project results underline the importance of measuring and modelling definition phase. Measuring and documenting objectives for 3D-model based design work are different than for traditional design work. Measuring survey has to be done under the coordination of the designer participants. Selecting and informing the proper and capable surveying partners is also important.

title	Collaboration in Parametric Design: Analyzing User Interaction during Information Sharing
doi	https://doi.org/10.52842/conf.acadia.2010.320
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 320-326
summary	Designers work in groups. They need to share information either synchronously or asynchronously as they work with parametric modeling software, as with all computer-aided design tools. Receiving information from collaborators while working may intrude on their work and thought processes. Little research exists on how the reception of design updates influences designers in their work. Nor do we know much about designer preferences for collaboration. In this paper, we examine how sharing and receiving design updates affects designers’ performances and preferences. We present a system prototype to share changes on demand or in continuous mode while performing design tasks. A pilot study measuring the preferences of nine pairs of designers for different combinations of control modes and design tasks shows statistically significant differences between the task types and control modes. The types of tasks affect the preferences of users to the types of control modes. In an apparent contradiction, user preference of control modes contradicts task performance time.

title	The Digital Environment of Urban Dynamic Analysis
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	Urban sprawl and complexity are increasing at an alarming rate causing huge energetic waste and affecting the quality of life of people and life on earth in general. This paper proposes Urban Dynamic Analysis as a feasible approach to address this negative phenomenon. Urban Dynamic Analysis is a multidisciplinary holistic method that inquires into temporal relations between structures and related characteristics in cities. A range of simulation tools are being adapted and developed aiming to assess different morphological configurations of urban spaces, to improve the welfare of citizens and to optimise energy consumption. All these tools are based on digital image utilization, with simple computational techniques.

title	Developing a Hybrid Intelligence Through Hacking the Machine Learning Neural Style Transfer Process for Possible Futures
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_25
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	This article highlights work using machine learning in collaboration with designers for speculative world building. The process is unique because of the feedback loop, between the designer and the computational process. Worldbuilding is a speculative practice and requires vision and courage on the part of the designer. Working with machine learning neural style transfer (NST) allows the designers to consider possibilities humanity may not otherwise allow ourselves to imagine. This is important because human imagination paves the path for the future of humankind. Imagining a sustainable future requires considering unconventional solutions. Imagining non-probable futures allows humanity to glean desirable aspects to strive for. Even if a conceived future is impossible within the built environment, there are many opportunities for people to inhabit these environments virtually. Letting yourself get lost in these places is a form of travel, even when conditions limit one's ability to physically do so.

title	Double Green Façades using Parametric Sustainable Design: A Simulation Tools with Parametric Approach to Improve Energy Performance of Office Buildings in Egypt
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 727-741
summary	Parametric Sustainable design of the indoor environment of double green façades buildings focus on the development of office building structure in Egypt and achieved indoor thermal comfort at a low level of energy use. The goal of this paper is to study parametric design from a wide perspective in order to classify its advantages and evaluate its skill to support Sustainable design. As building construction sector is the largest energy consumer, Operation hours of air conditioners is speedily increasing in the office buildings area through summer season, which already accounts for 50% of energy consumption in Egypt. This study was carried out based on the simulation in Design Builder (6) software. The case, studied in the article is for office building, newly erected building with surface area of 25, 500 m2 is considered as the basis for the parametric Sustainable study. The new energy model was simulated resulting in about 70% in HVAC consumption and approximately 75% for whole building energy consumption. Analysis results showed that parametric optimization of building envelope at the design stage is a practicable approach to reducing energy consumption in office building design.

title	A perceptually based physical error metric for realistic image synthesis
source	Alyn Rockwood, editor, SIGGRAPH 99 Conference Proceedings, Annual Conference Series, ACM SIGGRAPH, Addison Wesley
summary	We introduce a new concept for accelerating realistic image synthesis algorithms. At the core of this procedure is a novel physical error metric that correctly predicts the perceptual threshold for detecting artifacts in scene features. Built into this metric is a computational model of the human visual system's loss of sensitivity at high background illumination levels, high spatial frequencies, and high contrast levels (visual masking). An important feature of our model is that it handles the luminance-dependent processing and spatiallydependent processing independently. This allows us to precompute the expensive spatially-dependent component, making our model extremely efficient. We illustrate the utility of our procedure with global illumination algorithms used for realistic image synthesis. The expense of global illumination computations is many orders of magnitude higher than the expense of direct illumination computations and can greatly benefit by applying our perceptually based technique. Results show our method preserves visual quality while achieving significant computational gains in areas of images with high frequency texture patterns, geometric details, and lighting variations.

title	An Iterative Procedure for the Polygonal Approximation of Plane Curves
source	Computer Graphics and Image Processing. Academic Press Inc., August, 1972. vol. 1: pp. 244- 256 : ill. ; diagrams. includes bibliography
summary	The approximation of arbitrary two-dimensional curves by polygons is an important technique in image processing. For many applications, the apparent ideal procedure is to represent lines and boundaries by means of polygons with minimum number of vertices and satisfying a given fit criterion. In this paper, an approximation algorithm is presented which uses an iterative method to produce polygons with a small-but not minimum-number of vertices that lie on the given curve. The maximum distance of the curve from the approximating polygon is chosen as the fit criterion. The results obtained justify the abandonment of the minimum- vertices criterion which is computationally much more expensive

summary	This research is based on the problems faced by designers in the execution of models generated with the "Form-findind" design technique, due to the low or non-existent market proposal regarding the quality of materials capable of withstanding the stresses to which a model with complex curvatures is subjected; therefore, the use of agro-industrial pozzolans (sugarcane bagasse ash) is proposed as a 20% substitute for Portland cement to obtain flexible concrete, with the intention of evaluating the physical-mechanical behavior and its application to geometries based on force systems (catenaries) obtained from mesh relaxation through digital simulation, following the form-finding technique, resulting in a 16% superiority in compression tests of concrete with pozzolans compared to conventional concrete (control).

summary	Cultural changes based on recent development of information technologies suggests that knowledge could be spread with less control and greater accessibility, allowing the emergence of communities that launch alternatives like, for example, networks of laboratories for manufacturing. However, similar ambitions regarding the creation of alternatives to industrial production can be identified in the countercultural context of the 1960s and 1970s. This article traces some comparisons between these two historical moments with the goal of investigate how do-it-yourself (DiY) appears (again) in the design scene today as do-it-with-others (DiWO), establishing approximations and distances between two selected objects of study.

summary	This article describes the methods of an inclusive design project developed by FACAMP’s NIEDA , as demanded by the UNICAMP Science Museum (Brazil). The objective was to create a multi-sensorial interface that would be capable of describing the process of energy generation and distribution in a hydro-power plant. It began with a scheme based on images and a narration was built out of audible and tactile systems so that it would be comprehensible for the blind public as well, without compromising the aesthetic and informative aspects. It also reveals the challenge of combining the use of multiple technological resources, such as 3D printing and laser cutting.

summary	Silica examines the making of 3D printed tiles from recycled container glass. This paper describes an interdisciplinary exploration into how robot-controlled extrusion can offer new material practices by which to fabricate glass elements of an architectural scale. We pursue working with recycled container glass powder - a waste product derived from the reprocessing of recycled container glass - to contribute to circular development within an interdisciplinary artistic development context in the meeting between architecture and glass design. The project has two aims. On the one hand, it builds an in-depth understanding of the parameters of fabrication and devising means by which to control these through digital design methods and their interfacing with robotic fabrication processes. On the other hand, it critically questions the architectural, aesthetic and performative properties of these material practices and their embedded methods.

title	Generating a scalar logic: producing the "it's a SMALL world" exhibition
source	International Journal of Architectural Computing vol. 9 - no. 2, 115-132
summary	This paper presents the design project “it’s a SMALL world”, an exhibition design developed for the Danish Design Centre in 2009.The project investigates the making of a generative design environment by which multiple design parameters as from program, site or the subsequent digital fabrication and assembly process can be negotiated. In this paper we discuss methods for understanding the emergent interrelationships between encoded parameters, how to manage these and their impact on design.The implementation of the design necessitated a novel design method that allowed to blend the qualities of a generative design approach, that can adapt through recursion gradually to local requirements, with explicit definitions.The project showcases with its new developed manufacturing system for non- standard element how customized digital design and production tools allow for a novel nearness to material and new ways of production and collaboration of architects, engineers and the crafts.

title	An Architecture Model for Multimodal Interfaces with Force Feedback I.14 Virtual Reality 2
source	Proceedings of the Sixth International Conference on Human-Computer Interaction 1995 v.I. Human and Future Computing pp. 455-460
summary	Multimodal interfaces with force feedback pose new problems both in terms of their design and for hardware and software implementation. The first problem is to design and build force-feedback pointing devices that permit users both to select and manipulate interface objects (windows, menus and icons) and at the same time feel these objects with force and precision through their tactile and kinesthetic senses. The next problem is to model the interface such that it can be returned to the user via force-feedback devices: the task is to define the fields of force corresponding to interface objects and events, and to design algorithms to synthesize these forces in such a way as to provide optimum real-time operation. The final problem concerns the hardware and software architecture to be used to facilitate the integration of this technology with contemporary graphic interfaces. An architecture model for a multimodal interface is presented: it is based on the notion of a multiagent model and breaks down inputs and outputs according to multiple modalities (visual, auditory and haptic). These modalities are represented by independent software components that communicate with one another via a higher-level control agent.
