STUDIO BRIEF STUDIO X - Parametric Collaborations. Phase 1 (WS11) Course Summary: The research brief for the WS11 was to design a concept villa for the 21st century. In highly urbanized, highly mobile societies the house becomes an issue demanding further research and investigation, where the consequences of a materialistic society have devolved the idea of house to that of property. Yet, the house is where everyone’s life is formed and where everyone forms the home based on the living behaviours that stem out of social, family relationships etc. The studio’s interest in the way a villa can become a formal expression for, one or a group of lifestyles and values. This close relationship can be family, sexual, occasional, and professional. A villa is a culmination and the distillation of architectonic notions within a changing societal setup. The design of the villa will respond to the contextual content. The responsiveness of the design to the climate, the views, the site and the urban environment or lack of, around it is crucial to the task of this research. Phase 2 (SS12): Thesis; Team work & Collective Developments Following the submissions in the first semester the studio continues to explore the notion of housing as a result of design agendas that can be combined to deliver an outcome that can be implemented either as a Masterplan, a city intervention, a tower or other large scale development. The students have been asked to form teams based on shared sensibilities and work ethics and to propose a thesis that underlines the team’s design interests and combined agenda. The aim is to fuse the combined ideas into a larger architectural proposition, find ways to mitigate problems and to propose ways to deal with the multiplication/ proliferation of the concepts in fields of multiple units.

ARCHEOLOGIST VILLA It is located in Persepolis or Takht-e Jamsid (The City of Persians), Fars Province, Iran. It is approximately 70 km northeast from Iran modern city, Shiraz. It was the ceremonial capital of Achaemenid Empire (ca. 550330BC), by knowing that Persepolis is an archeological site where traces of ancient Persian human activity are found, the methodology of learning, observing, through Persepolis ruin or artifacts is a prerequisite. Archeologist villa tries to merge the ancient Persepolis study of proportions and volume with digital architecture approach. My aim in this proposition is to create a new relationship that are related closely with the existing context and content from a specific site in order to be able to produce a new element that are being influenced by the existing site and also to define the new use and meaning that is suitable for 21st century villa requirement. Having arrived in this 21st century which I found it’s abundant complexity that come from inside and outside architectural fields, what is needed to be reconsidered for architects are how the grasp thinking for particular projects nowadays in the extensive observations with all ease from the advance technologies development without disobeying all the real aspects of designing for society, and it has to be balanced with the consideration to what architecture or built form that is done could provide in dynamic society with dreams, projective, engage with reality, consideration of the ‘desire’, and not to abandoned but to rethink and react to what are already successful out there, reflexivity, critical thought within the right specific context. In conclusion the villa idea is producing a new ratio and proportion either for the overall form or for the interior purposes that is fitted to the users both male and female.
The villa is designed for Sherief Sheta, professor of architecture at Mansoura University. His research focuses on sustainable architecture (planning and design) with particular interest on design development theories and techniques. SolarSinter villa tries to represent the lifestyle of the client, substantially merging life cycle of each family member, their relationships, creating comfort indoorenvironment for their life and activities. Villa is located in the desert between Alexandria and El Alamein /Egypt/. The main idea is based on non-additive processes /building with materials found on site: sand as an abundant and free material source, sun as an energy source and the emergent of sand sintering process/. One of the ideas of this project is to explore several techniques which are helping to solve specific problems by using the collective intelligence. The collective intelligence comprises of simple interacting agents composition with the intelligence which lies in the synergy of networks between the individual and individual with the environment. In order to achieve desired results I was using several classes of agents that are responsible for: - scanning system Agents that are scanning the terrain and shallow surface of the dunes in order to analyze the type of materials and to adjust the structure of the building. - spatial organization Agents (rooms and spaces) are coordination their position according to proximity/circulation diagram and topology of the terrain. - programmed circulation Agents /MA/ are mimicking the movement of the family members inside the house /developing different scenarios of the family behaviour/ - structure Agents are following the MA and building the structure according to the amount of time that MA are spending inside of the spaces. - printing Agents are solar- sintering the sand in order to solidify it and create structure.
VILLA FOR XXIST CENTURY SCIENTISTS
Illustration from: “Hyperspace: A Scientific Odyssey Through Parallel Universes,Time Warps, and the10th Dimension by Michio Kaku
I was asked to design a villa for Leonard Susskind, the so called « father of string theory ». 72 years old already, grown up children and divorced, the scientific community gradually became his own family. Still very active as a researcher, he recently created the Stanford Institute for Theoretical Physics (SITP), an institute to support the research in theoretical physics. The institution brings physicists from the entire world to Stanford for lectures, seminars,... It’s aim is to play the role of a catalyser in the development of the research in physics. Thus, the villa will be set as a big family house for the institute’s guests: they will be received all along the year, until 8 person at the time and it will provide the best conditions for guests to interact with each other, to develop new ideas for the future of science. String theory, as an attempt for a theory of everything, proposes to join the two main scientific theories of the 21st century: the theory of general relativity and the quantum theory. To solve this issue, physicists had to find an explanation to the phenomenon of the black-holes. They came out with the multiple-universes hypothesis, where wormholes create space-time shortcuts between black-holes and white-holes of different universes. The Villa for XXIst century scientists was developed according to the geometry of wormholes and their property of continuous spaces.
CONCLUSION
After merging three main topics /which were scanning process, excavation and continuous surfaces techniques/ we concluded that the thesis project aim is to demonstrate process of building in a desert condition with robotized processes which are being arranged with a few strategies such as scanning the terrain to know the topographical condition and classifying different materials to produce height map, identifying the highest rock location from sand surface, excavation strategy that is depending on the scan result, functional arrangement distributed accordingly, series of deep cut to the lowest ground, narrow pathway, by sintering the sand continuously will allow to create multi-layer spaces. We envisioned this proposal would be implemented in a larger scale with low labor forces, less water usage for construction, emphasizing sun energy absorption, reducing heat gain.
THESIS STATEMENT
Primarily our architectural investigation are based on our mutual interests of non-additive process (building with materials found on site), sand as an abundant and free material, sun as an energy source that has big potential for future development, and the emergence of sand sintering process. We have chosen a site in Algeria, El Bayadh Province, El Abiodh Sidi Cheikh as our case for further research investigation, because it is one of the most endangered area by desertification, it has already infrastructure (i.e. airport,road networks, etc), and it needs an activity generator to ameliorate the current condition. We are proposing an Environmental Scientist Village that will be a collaborative place between the local’s and researchers to find architectural solutions, to develop the technology for locals to adapt this climate change, and also to test robotized building processes as our main topic. It is a research center for housing development in desertification endangered area which comprises: houses, a research centre, a civic centre, a mosque,
D U N E LAB
a school, shops, agricultural facilities, a sport centre, infrastructures and open spaces. Our project is a masterplan that is being informed with the landscape previously scanned by swarming robots in order to be able to classify certain geological condition, to produce the network structures on site. It is a non-additive architectural approach highly interrelated with the landscape through the creation of an artificial terrain that has multi layer spaces and machinic ornamentation. The project is being developed through multi-agent system that are inspired by nature, in our case desert, dune field patternformation, desert erosion processes, which are proliferating continuous spaces that have striated, contoured, cavernous surface aesthetics. We are envisioning with the addition of digital tools an advanced industrial process that would allow to create more responsive architectural solutions, low impact materials, which will lead toward better efficiency, and also more economical for long term use.
ENVIRONMENTAL SCIENTIST’S VILLAGE Environmental Engineering Research Center for housing development in desert area. INTRODUCTION.
Having arrived in 21st century, there are many problems regarding the environmental conditions that are caused by global warming, excessive population growth, unstoppable global migrations, the spread of deserts, and so forth1 . In fact one quarter of the earth’s land is threatened by desertification, according to estimates by the United Nations Environment Program (UNEP). As defined by the UN Convention, desertification is a process of “land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities” which will affect on loss of biodiversity, global warming2 . In a festival celebrating “Cultures and Civilizations of Desert Peoples” in December 2002, President Bouteflika told the audience that “Algeria lost, each year, 40,000 hectares of its most fertile lands because of desertification.”3 We are interested to address the issue of housing in desert condition as our main topic; therefore we are proposing an environmental scientist village that is dealing with this question. For example United Nations Environment Program researcher, environmental engineers, anti desertification group, and volunteers will be gathered in this village and try to address the desertification issue by the application of science and engineering principles to land resources in order to provide water, land for small habitation, vegetation, food production, energy. Hence we are proposing new possible material research in this particular case, sand or rock that could be optimized with the advanced fabrication technology, where we would emphasize the idea of zero material transfer, and also in our architectural concept we are generating the form from the existing material. “With the addition of digital and advanced industrial processes should allow us to create more responsive devices and low impact materials that will lead toward better efficiency, and also more economical for long term use.”4

ADVANCED TECHNOLOGY We are inspired by the invention of sand sintering solar system and also other technological development on the advanced tools for example robotic CNC drilling machine, composite 3D printing machine, geological scanner which could enhance the architectural production not based on ready products but instead being self sufficient, by reinventing the available source on site. “Decoration has evolved into a new paradigm for the relationship between structure, form, and aesthetic in architecture.[‌] With the era of advanced technology the aesthetic has already embedded within the production of the overall objects or architectural form that has a machine aesthetic in it.â€? Technology and natural resources are related to our current methodologies in manufacturing, to reveal new opportunities and test scenarios of architectural production which is implemented within the process of optimizing the use of solar energy and power resins with silica that we found in the sand.
MA DESIGN PRODUCTS STUDENT PROJECT // MARKUS KAYSER
This project explores the potential of desert manufacturing, where energy and material occur in abundance. In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology. By using the sun’s rays instead of a laser and sand instead of resins used in modern 3D printers, Markus had the basis of an entirely new solar-powered machine and production process for making glass objects that taps into the abundant supplies of sun and sand to be found in the deserts of the world. The Solar-Sinter was completed in mid-May and later that month Markus took this experimental machine to the Sahara desert near Siwa, Egypt, for a two week testing period. The machine and the results shown here represent the initial significant steps towards what Markus envisages as a new solar-powered production tool of great potential.

INITIAL RESEARCH ROBOTICS
BIOLOGICALLY-INSPIRED. HEXAPOD ROBOTS A hexapod robot is a mechanical vehicle that walks on six legs. Since a robot can be statically stable on three or more legs, a hexapod robot has a great deal of flexibility in how it can move. If legs become disabled, the robot may still be able to walk. Many hexapod robots are biologically inspired by Hexapoda locomotion. Hexapods may be used to test biological theories about insect locomotion, motor control, and neurobiology. X-RHEX: A HIGHLY MOBILE HEXAPEDAL ROBOT FOR SENSORIMOTOR TASKS Using the internal IMU and a payload laser scanner, X-RHex can create a 3D point cloud of its surroundings. Six powerful motors actuate compliant legs, allowing X-RHex to traverse a wide variety of terrains, including asphalt, grass, sand, mud, and rocks. By using a mil-spec rail mounted interface and standard electrical connections, X-RHex can support a wide variety of payloads, making it a mobile “laboratory on legs”.
INITIAL RESEARCH ROBOTICS
SWARM ROBOTS. A Low Cost Scalable Robot System for Demonstrating Collective Behaviors Swarm robotics is a new approach to the coordination of multirobot systems which consist of large numbers of mostly simple physical robots. It is supposed that a desired collective behavior emerges from the interactions between the robots and interactions of robots with the environment. This approach emerged on the field of artificial swarm intelligence, as well as the biological studies of insects, ants and other fields in nature, where swarm behaviour occurs.

Barchan ridge
Predominant wind direction Barchan dunes is a crescent shaped dune which commonly formed in relatively flat sand surface, limited supply of sand, and flow of wind from one direction. Barchan ridge is a row of connected barchan dunes which occurs in relatively varying type of sand surfaces, greater supply of sand.
Reversing dunes Transverse dunes is a long asymetrical dune that form right angles of wind direction, formed relatively from weak winds and abundant supply of sand with single long slip face.
Source: http://courses.missouristate.edu/EMantei/creative/glg110/deserts-wind.htm
Seif dune or longitudinal dune is a long dune (could be more than 100km long and 100m high), the dune ridge is symetrical and it has slipfaces on either side, and it is formed by strong winds at least from two directions.
Complex dune is a dune that is formed when the predominant wind are varying therefore it is forming linear, star, and reversing dunes.

SITE SELECTION
SITE SELECTION We are proposing the site in Algeria, it is the largest country in Africa and the Arab World, and it is covering approximately 2,400,000 sq km of land area. The land are comprises of arable land which is 3.17%, permanent crop that is covering 0.28% and desert is 96.55% (in 2005) . We are seeing this as a possibility to examine new material use, while also addressing the desertification issue with our proposal of environmental scientist’s village. The ranges of environmental concerns in Algeria are biodiversity, Climate Change, Desertification, migration and poverty. The site is located in El Bayadh province that is divided to 8 districts and 22 municipalities. The desertification sensibility map showed that this province is one of the extreme place toward desertification, therefore the location of Environmental Scientist’s village will take place in this area, where the nearest airport location is in El Abiodh Sidi Cheikh. It will be approximately 100km from El Abiodh Sidi Cheikh Where the village will start developing the method of anti desertification and get connected with the adjacent city.

SIMULATIONS CELL TEMPERATURE, AIR FLOW, FLOW VECTOR ANALYSIS
From the computational fluid analysis that we understood at the lower level of the sand surface that absorbs heat, there is an urge to add shading to reduce the heat gain over the sand surface that will allow the area to be inhabited. The airflow rate and wind flow are parallel on the closest part from the sand surface is slower and where there are no obstacle above ground the speed increase.

The simulation initially started to reveal the variety of surface deformations that are caused by wind that occured through time from the actual form until the final deformed form. Simulation was tested with maya dynamics by using its embedded field conditions wind, gravity, object stiffness, etc. The result showed multiple variations that are depending on the wind magnitude, velocity, gravity. In order to have different result on simulations, the object weight set to 0.5 which works in between the predetermined value in the dynamic system from 0 (black-soft material) to 1 (white-stiff).

SIMULATIONS WIND EROSION SIMULATION
We are seeing erosion processes in the desert as a device to shape the site and to create aesthetic effects in the architectonic production. In this case wind act as an active agent that changes the building and environment through time. By studying and simulating the erosion process allow us to manipulate and control the effects of erosion on the interior and exterior through continuous spaces.

Glacial erosion simulation was done by setting or colliding two different particles in a system and by setting up several parameters, which are depending on collision, bounce, friction, stickiness, gravity, and wind. On the diagrams on the right the test was done in several scales to imagine the land transformations or effect that are created through time. The process of glacial erosion was happened in a large scale fracture. The physical factors that are affecting the simulation was gavity, air, wind speed and direction. It is built to analyze with several natural forces that could be set according to our need. In other words, it is controllable simulation that could be usefull for surface or geometry production that are informed or representing erosion potential as a tool for architectural design.

We envisioned that this topological configuration is working dynamically/harmonically as above ground structure and base structure as well and by creating this type of configuration will allow for space expansion underground which are ideal for desert condition.

We are seeking to create spatial quality of spaces that are informed from hierarchical network diagrams, which we adjusted to the design by distinguishing the main and seconday branches, number of connections

CONCLUSION PATTERN STUDY
We have tested several conditions that are depending on type of surface divisions that are creating different densities and we conclude that we are using regular grid for the main structure, because the densities that are needed to give shadow on site is sufficient and iso curves arrangement as circulation network was chosen because it is optimizing the structure with a compact arrangement.

SCANNING TECHNIQUES ROBOT DEPLOYMENT STRATEGY
Scanning techniques were tested on several notions, which are monocentric, polycentric, corner swarms, ripples, triangulate scanning strategy. The scanning robots are developed to avoid obstacles in this particular case are high rock formation and by applying this technique would allow us to generate the height map of sand, clay, rock on site are informed by scanning robots for the the next strategy of excavating, printing, and settling the buildings on the site.

EXCAVATION TECHNIQUES EXCAVATION PATTERN
Linear excavation pattern are optimum to achieve elongated arrangement, the connection between nodes are very limited to the linear path.
Triangular excavation pattern are creating compact connection between and creating rigid connection between nodes and it is very efficient for creating connection between nodes.
Different triangular excavation pattern are creating more dynamic between nodes and also creating multiple hierarchical system.

PRINTING PROCESS MULTIPLE LAYERSprocess STRATEGY Sand sintering is being
done sequentially starting from the below. Several layers for main and secondary structures, and concurrently building are being printed after excavating process or preparation by taking the advantage of sand repose angle.
PRINTING PROCESS From the optimized pattern on site different densities for printing was tested, the desirable consideration is to create the right balance for desert living condition, which are characterized mainly solid in order to protect from direct sunlight, maintaining interior temperature to be cooler than outside temperature, porous material in micro scale.

CONCLUSION To be able to occupy desert for a better living condition there are several basic understanding that was driven from our CFD analysis which informed the design to be adjusted accordingly. Architectural intentions were driven to mitigate the extreme condition in desert. By adding structural elements that works as shading system as well as a structure for functions or building, we are allowing horizontal and underground expansion. The understanding of wind pattern will reveal architectonic qualities that are depending on time: for example, from a range of 50 years the sand sintered building will get deteriorated by ventifacts or yardang. In the same time the design process is extended with series of future predictions. The use of continuous geometries optimizes the distances between spaces, the amount of material used, and creates heterogeneity in the space arrangements within the given existing landscape. In the same time, we will create an artificial landscape that is contrasting but adapting to the topographical conditions. The integration between building and landscape are formed by the sand 35° repose angle condition that is constraining the printing process. Series of retaining walls are being introduced to protect the building from the extreme environmental conditions, as well as narrow cuts or openings to control the light intensity, narrow pedestrian pathways that are protected, striated wall conditions, integrated furniture from materials, shading system that are combining fabric or textile that wouldn’t increase the structural load but in the same time intensifying the habitable shaded area. Scanning the landscape to find the best location for structural foundations allow us to extrapolate further to other locations. Swarming robots are quite successful on creating network organizations adapted to unknown sites. D U N E LAB
