summary To advance the theme of digital conservation of heritage and tie it to museums, we report on two case studies of digitising archaeological sites; the first is the remains of a typical Scottish Crannog typical of the sixth-century BC., and the second is a UNESCO protected site in the Middle East (the desert castle of Qusayr Amra, Jordan), which dates back to early 8th century. Then we relate both to our investigation into embodiment, interaction and metaphor in virtual environments.

title Daylight Optimization - A Parametric Study of Urban Façades Design within Hybrid Settlements in Hot-Desert Climate
source Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 2, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 193-202
summary Unprecedented growth of hybrid settlements causes deterioration to the indoor environmental quality. Due to their narrow street-networks and fully packed urban fabric, lower floors are subjected to severe overshadow condition, which has adverse effects on the health of the inhabitants. This paper aims to investigate techniques to mitigate the under-lit indoor environment for a group of buildings with variable heights and orientations, with regard to the urban façades parameters. It reflects an intervention in an existing hybrid settlements, within hot-desert climate, to alter façades configurations for daylight optimization, and ultimately recover the lost indoor quality of users in such contexts.

title Adaptive architecture: integrating low-energy technologies for climate control in the desert
source Automation in Construction 6 (5-6) (1997) pp. 417-425
summary The article describes a `climatically adaptive' approach to intelligent building in which a variety of technologies are integrated in the architectural design to provide thermal comfort with a minimal expenditure of energy. This concept is illustrated by the design of the Blaustein International Center for Desert Studies, a multi-use complex completed recently at the Sede-Boker Campus of Ben-Gurion University of the Negev. In response to the local climate of this desert region, a number of strategies were developed by the authors to exploit natural energy for heating and cooling: earth berming of major parts of the building, 'selective glazing' for seasonal shading and energy collection, a down-draft 'cool-tower' for evaporative cooling and a hybrid mechanism for hot-air supply are several of the unique systems whose performance and feasibility are analyzed within the context of the overall building design.

title Man + Water + Fan = Freshman: Natural Process of Evaporative Cooling and the Digital Fabrication of the ASU Outdoor Dining Pavilion
source Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 208-213
summary To the east of Johnson City TX is the Lyndon B. Johnson’s family home. Part of the Johnson Estate2 is given over to a working farm circa 1870 that presents various aspects of domestic practice from the era. This includes a desert fridge which is a simple four-legged structure with a slightly battered profile that’s draped in calico. Its principle is simple; water from an upturned jar is drawn by osmosis down the sides of the calico where it evaporates in wind currents drawn though a “dog run” between two log cabins. Cooled air circulates within the structure and where cheese and milk are kept fresh during the summer. The desert fridge is a simple system that reaches a state of equilibrium through the natural process of evaporation. ¶ This system provides a working model for a prototype structure for an outdoor dining pavilion that was designed and constructed on the campus of Arizona State University. The desert fridge is the basis for a “biological process”3 of evaporative cooling that has been interpreted in terms a ritual of outdoor dining in arid climates. The pavilion is intended as a gathering point and a place of interaction for ASU freshmen. The long-term aim of this project is to provide a multiple of these pavilions across the campus that will be the locus of a sequence of dining events over a “dining season”4 during the fall and spring semester. ; This paper describes how the desert fridge principle has been interpreted in the program and construction of the dining pavilion. It explores a sequence of levels by which the structure, via digital production process, provides an educational narrative on sustainability. This communicative quality is portrayed by the building in direct biological terms, through tacit knowledge, perceived phenomena, lexical and mechanical systems. The paper also describes how these digital production process were used in the building’s design and fabrication. These range from an empirical prognosis of evaporative cooling effects, fluid dynamics, heat mapping and solar radiation analysis through to sheet steel laser cutting, folded plate construction and fully associative variable models of standard steel construction. The aim of the pavilion is to create an environment that presents the evaporative cooling message at a multiple of levels that will concentrate the visitor in holistic understanding of the processes imbued within the building.5

title Sandworks / Sand Tectonic Prototype
source ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 81-94
summary This paper outlines a material based research that proposes a time-based architecture that extends Frei Otto’s research of sand formations using sand’s natural angle of repose. The tectonic system focuses on developing compressive structures of sand for hot climate desert areas through a zero-waste formative process whose architecture reorganizes materials naturally available on the site. Formations are hardened as a surface through the phase changing properties of a saline solution which crystallizes when cooled, bonding with the sand. The proportion of insulation material defines the building life span redistributes the materials back into its environment at the end of its cycle. The materiality and spatial qualities of the project are based on the conical and constant angle surfaces generated through the gravitational process of sand formation. Between the digital opportunities of sand formation and its physical possibilities, this paper outlines the analogue-digital methods of sand computation through a comprehensive study in four main sections; material system, material computation, design system and robotic fabrication.

title Virtual Reality Model of the Northern Sluice of the Ancient Dam in Marib/Yemen by Combination of Digital Photogrammetry and Terrestrial Laser Scanning for Archaeological Applications
source International Journal of Architectural Computing vol. 5 - no. 2, pp. 340-354
summary In this paper the potential of digital photogrammetry and terrestrial laser scanning in combination is demonstrated in the recording and 3D CAD construction of the northern sluice of the ancient dam in Marib/Yemen, which is located approx. 150 kilometre east of the capital city Sana'a, close to the inner Arabic desert. The Yemeni government proposed for initiation of the building into the list of the UNESCO world cultural heritage. This described project work is a co-operation between the Commission for Archaeology of Non-European Cultures (KAAK) Bonn of the German Archaeological Institute (DAI) and the department Geomatics of the HafenCity University Hamburg. The object recording was carried out in January 2006 with the digital SLR camera Fujifilm FinePix S2 pro and the terrestrial laser scanner Trimble GS100 during the archaeological excavations. The northern sluice was reconstructed and visualized as a computer-based 3D CAD model for archaeological investigations (as-builtdocumentation of the excavations) and for future tourism advertising and publication purposes.

title The Nazca Lines and their Digital Architectural Representation
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary This paper relates to a digital architectural design experience in 2005 for the Nazca Competition. Nazca is an archaeological site situated about 400 kilometers south of Lima, Peru. It is a large desert with gigantic millenary geoglyphs carved on the surface, which can only be seen clearly from above. The Nazca geoglyphs are made up of hundreds of lines, spirals and triangular plazas, as well as zoomorphic figures like birds, fish, spider, etc. The Nazca Competition asked for an observatory-lodge of approximately 1.000m2 with 20 rooms, communal bathrooms, supporting areas and an observatory tower of at least 100 meters. The observatory-lodge was designed using a digital representation technique called "Genetically Constructed Structures". The structure was created using the geometric principle of the affinity of two conic sections: circle and ellipse. The form was produced transforming the circle and the ellipse by performing basic geometric transformations (translation, rotation, reflection and scaling). According to this technique, the sequence of transformations was codified in the form of an alphanumerical string, metaphorically named the "DNA structure". The code was inserted as extended data into the entities which shaped the structure profiles. The algorithms were programmed with AutoLISP language. The "DNA code" allowed the structure to be constructed and deconstructed from any point, generating many different forms, to be studied and compared. One year later, the same 3D model was used to test another digital technology called "musical box" where their geometrical points are captured, read and translated into musical parameters, generating music. In this paper we will present the graphical form of the tower as well as the music associated.

source ACADIA Quarterly, vol. 18, no. 1, pp. 24-25
summary It’s 1999: Yes! We are at the eve of the new century. As I plan my Quarterly Review, I am compelled to search for a site that peers into the future. Of course, the perfect site also contains fascinating graphics and mind grabbing information. Though the Internet as gained galactic proportions since its inception, sites containing both excellent graphics and cutting-edge discussions are an oasis in a desert of triviality.

summary With fast growing population rates and the further desertification of the global climate, desert regions, covering one fifth of the world's surface, provide an opportunity for future habitats. However, their extreme climatic conditions and remoteness pose a planning challenge, currently addressed with prefabrication and layered design; wasteful and costly solutions. This article proposes a bespoke design, fabrication and assembly process: performed in-situ with using local resources and novel automation. The research addresses challenges in on-site robotic forming and assembly of mono-material discrete elements, made in waterless concrete of sand-Sulphur composite. The formed components are examined in formwork-free assembly of wall and arch, with Pick & Place tool-path. The component's design incorporates topological and osteomorphic interlocking, facilitating structural integrity, as well as self-shading and passive cooling, to fit with local climate. This work culminates in a design proposal for constructing desert habitats, climatically adapted for Zagora oasis in the Moroccan Sahara: a remote site of hyper-arid climate.

source T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary This investigation arises from the need to include the systems of environmental natural conditioning and the architectural project in the ecology of the desert dry-climate. In this research, it is proposed to investigate the main features and techniques used in Southern Peru as an answer to build in a desert environment with high levels of sunlight and very few rain days. Identifying the historic processes of the vernacular architecture, in which we recognize evolved coherent forms, making possible to define the strategies with which to recreate architecture responsive to the ecology of the desert dry- climate.
