Studies 1:1 NUBULAR lightweight structure
The Nubular lightweight structure is an exploration into an injection-based architecture. A homogenous building material, in this case a perforated PVC skin, is used to create tubes of custom lengths and angles, which are then filled with one’s material of choice depending on the chosen tube’s position within the overall structure. Given that the material filling is a key parameter in the behaviour of the elements, several tests were carried out to identify the optimal fillings and member lengths to avoid buckling. It was decided to fill the bottom most members with a soil and sawdust combination while the top is composed of lighter foam balls. Each tube length is split into 3 with a maximum part length of around 800mm and allowing for 50mm flat connection gaps in between and on the ends. The overall shape was designed in Grasshopper using the Hoopsnake plugin. A original tetrahedron shape is drawn and hence follows the path of an arched curve, turning and repositioning itself in the process from the start of the path to the end. After this process, the geometry was manually pulled to the ground plane and specific 3-piece curves were extracted and drawn to ensure they stay under the 800mm limit. Each of these curves was separated as a layer and with lengths fed into another definition to directly produce laser cut files which included labels and welding line engravings. The fabrication process took about 3 full days. 78 custom lengths were laser cut, welded, filled, and holed at the junctions for connections with zip-ties. Construction took around 10 hours, as we constantly referred to the digital model to identify exact angles and connections of each length to the next. Ultimately the structure was a success and we learned a lot about the structural capabilities during the construction process. In parts where our soil/ sawdust combination was weaker or poorly packed we noticed much more buckling, while the foam was stable for the most part given its very low weight. Future constructions could benefit from digital structural analyses to clearly identify weight/strength ratios of different materials in different locations of the structure and to remove redundant members while adding ones where needed most. The implications for such architectural systems are vast, however; as the tube skin can accommodate for any desired material injection, dependant on one’s exact design, site, and structural needs.

Studies 1:1 FOREST VIBRATIONS public space capsule
The Forest Vibrations pavilion is based on a few key concepts related to physics, geometry, and space. There are two main outputs from the resulting proposal; first is the translation and amplification of everyday sounds of the city of Santiago de Compostela, and second is the visualization of audible sounds through their vibration within materials. The result is an instrument which outputs a sensory experience to its users through he use of an articulated roof structure. As frequencies are translated from the city, the dynamic space changes both through the disrupted perspectives of its users as well as the physical properties which are exhibited in materials when they undergo stress from vibration. This proposal outlines the design of a 5 x 5 x 3m pavilion composed of a metallic base, rigid acrylic or glass waffleroof structure, and 750 lengths of black PVC strips, tensed vertically from the base to the roof. The roof shape is articulated such that it forms 5 different lengths of PVC by pinning it at specific heights. This derivation of height has a particular logic based on the number of members in each family and their distribution in the space, but the goal is a combined effect of randomness and familial zoning within the space. From the outside, the pavilion is an alien. It is at odds with the environment in both its materiality and immaterial exhibited properties. The gridded distribution of vertical members inside the space simultaneously offer porosity and density depending on the viewer’s perspective, and conceptually reflect the behavior of a ‘cloud’ or forest. The material mirrors its surroundings, creating an oneiric ‘dreamscape’ through a distortion of the sky, the forest and the horizon The pavilion interior consists of narrow paths cut out of the otherwise evenly distributed density of vertical PVC strips. Users experience a sensory detachment from reality in this oneiric space due to the distortion of the inputs of light and sound.

Studies 1:1 PLUJA DE LLUM IAAC - BCN Llum Festival
The intimacy of the existing courtyard, located at Carrer de Santa Llúcia, 1, its distinctive elements, among which the lovers palm tree and fountain, as well as the well-known tale of the Saint Eulalia, together fed the concept of Pluja de Llum. The concept of the installation follows a mixture of the elements of the tale of Santa Eulalia, in particular her tears, transforming these into a conceptual rain. A luminescent rain, a rain of light, emanating from one of the protagonists of the courtyard, the palm tree. When entering the courtyard, the visitor is not fully made aware of the scenography that the courtyard beholds. The internal patio area is seamed off, leaving the visitor to meander through the porch of the courtyard, and being able to perceive, through a series of small holes in the sealing of the interior patio, or snapshots, what is in fact happening: the luminescent rain falling from the central palm. The visitor is then called upon reach up to the superior level of the patio, through a sound interaction system, defining the intensity of the light, and finally opening them to the infinite rain of the courtyard. The visitors look down upon the luminescent rain, into an apparently infinite well – reminiscing the existing fountain -, the courtyard itself, transformed through the implementation of a reflective surface – water flooding the ground floor of the patio – making the patio finally seem never ending through the infinite reflection, as the rain of light itself. Hence Pluja de Llum – or luminescent rain – proposes itself as the dialogue between the intimacy of the existing courtyard, as the tears of a young girl, and the proposed infinity that emerges, reflecting the perseverance of the tale of Santa Eulalia, and finally the festivities invoked by the BCN Llum 2015 festival.

Studies 1:1 LASER PAVILION FAB 10 Barcelona - FAB Kids
For the Laser Cutting Workshop, we focus on demonstrating the process of constructing three-dimensional objects from flat surfaces through laser cutting technique. To do this, we developed a modular installation to be built in different steps during the workshop. The design and manufacture of workpiece was done a week before to the workshop. To assemble the installation, the first step was to collect photographs of children and show them the general idea of the process of converting a vectors image into a “raster” one throughout specialized software (in this case we use Grasshopper). Then, and working in pairs, they began to assemble the pieces to create three-dimensional modules for attaching them to the other to create the installation itself. PROGRAM -Introduction to Digital Fabrication through laser cutting machines, its uses and applications. -How to manufacturing a three-dimensional object with flat surfaces. -Use of laser cutting machines for cutting, engraving and raster of pre-designed parts. -Handling the machines interface and the file preparation for engraving and cutting. -Knowledge of material properties and choice of working desk. -Assembling the laser cut pieces into the overall installation (techniques used “press-fit construction” and “waffle”).

Studies 1:1 DIGITAL FABRICATION approach to digital manufacturing techniques
1. 3D PRINTING The Metamorphosis project is a series of geometrical moments obtained by stretching an assemblage of arched rods. There are 3 types of 3D-printed joints: the base joint (B) fixes the structure to the board, the “plug” joint (A) slots in and twist-locks into the base joint, and the ”slider” (C) connects and moves along two adjacent rods. The geometrical moments can be created by changing the position of the plug joint in the board, or also by moving the base joint into the laser-cut holes. The chosen arrangement either expands or contracts the shape of the metamorphosing caterpillar whilst the slider deforms the body in various axes. Finally, the addition of a hinge in the board allows for the compression of the structure at an different angles. Combining 3 different strategies, the object (or parts of it) can be stretched compressed and twisted into an infinite number of geometries. 2. CNC - MILLING MACHINE our task was to revisit the famous Panot hexagonal cement floor tile designed by Gaudi in 1904 and generate our own design tile with new technologies like the CNC milling machine. The task began with the development of the pattern as a three dimensional treatment of the top surface of the tile considering a height restriction, the channeling of water through the tile and the possible connection to our own or others tiles. Our design was generated from two spirals, each in different direction, that meet in the center. This lines are then carefully projected to a cone that thanks to its slope water can be drained out. Also a special piece of wood is laser cut with the team’s fingerprints design to put it in the mold when casting to achieve an extra pattern. 3. LASER CUTTING TECHNIQUE Our main idea is to explore the potentiality and limitations that the material could achieve, through theoretical study and various practical tests. We enclose our research in 5 key points that have helped us to work with a scientific method through this research: A.. FLEXURE – TORSION B. HEIGHT C. TAPERING D. STRIPES E. ZIPPER We decided to follow the angle connection (zip tensile forces) after searching and tried different types of joints and cuts in order to obtain different movements and stiffness. Using 3D models we designed the general form of our tower, trying to push it to the maximum limit towards the research of materiality through the form.

Studio Work We5 Wind Energy Machines
The main aim for the wind machine is to start a production cycle of plants, which can be used in the daily life of Valldaura GreenLab. The wall is producing energy with windturbines. The energy is used for pumping water to the crops. The machine uses waste products from the house in the form of grey water and compost. The structure is built out of hemp, which the plantation can grow.In this way the production cycle is a living cycle itself. PROTECTION FOR CROPS A wall protects a plantation from the strong wind from the north, and allows the sun to reach the plants from the south. The small plants are placed near the structure, because they need more shelter from the wind. WALL PRODUCE ENERGY The wall produces energy through windturbines and feeds the plantation with water. The wall also collects rainwater into a tank, which is connected to the grey water from Valldaura. DESIGNING SLOPE AND PALES To protect, cover and increase the wind speed to the turbines, pales were added. The pales have two main aims; one is to direct the wind towards the turbine, and second is to accelerate the wind speed. The twisting design of the pales helps in achieving the objective and also creates a venturi effect. The pales are shaped as NACA foils, so they reduce the turbulence inside the slope VALLDAURA The structure is a new wall merging into the environment of Valldaura. The house of Valldaura is supported by retaining walls made out of local bricks. When the road was made to Valldaura, natural stone was exposed. The new wall component is the juxtaposition between the stone wall and man made tile wall.

Studio Work LGB - Solar House Solar Decathlon Europe 2012
The LGB Solar House [1] it projects a limited size house that meets the parameters of the Solar Decathlon competition. Sustainability from the point of view of energy and prefabrication are some of the requirements requested. An essential contribution for the purposes of formal choices, and especially typological was provided by a comparative study between a traditional and a contemporary architecture such as the Roman domus (sixth century BC) with the project Straw Bale Eco-House (2001) by Luis de Garrido. The basic idea is resume from tradition, those qualities that have subsequently led to the continuous evolution of our project. “Each ‘new’ masks always a return to the past.” G. Duby As the domus, LGB is also characterized by a stereometric form, compact outside and articulated inside. The archetype of this feature is the Mediterranean patio-house . The expressive concept of our Eco-House is a cave drawing found in the lucania caves , near Matera, symbolizing the natural need of shelter. After deciding the referencial models and having studied the coordinates of the lot from the competition (Madrid, Spain), we continued with studying and researching the different sources of revenue and energy production. All of this closely related to the needs and benefits of a family of 3/4 people, obviously without neglecting the sustainability aim of the competition. We can define the LGB-House as a self-sufficient and living organism : -no need for air conditioning systems, -no need for water supply, -do not need to connect to the urban sewer, -produces the need for its occupants: fruits, grains, tubers.

Studio Work ATMO_House Torre Barò Self-Sufficient District
The initial design decisions started from the limitation of the site, defined both by urban legislations and by natural existing elements. These limitations composed the “negative space� - the surface in the 3d space that the future building does not touch. After several solar analysis, the most shaded areas were added to the negative space. The spacial evolution of the design followed the parameters of light, heat and efficient space distribution, as well as minimal surface touching the ground. The skin followed the same logics but in parallel it suffered optimisations for improved solar gain. The skin split into one passive protective skin that follows the logics and activities of the house and one active skin that follows the sun path. The result is an atmospheric house which can change during the season with the passive textile skin and the active energy producting skin. During the summer the skin expands releasing a greater ventilation. During the building is contracting to decrease heated areas and keep the warmth inside. The active skin is shaping during the summer and producing electricity through flexible OPV-panels. In winter the skin angled to let passive sun heat reach the passive skin to heat the house up. The Atmo’s purpose is to bring to Torre Baro a re-interpretation of the local sense of place. The transparency of the construction is meant to be a way to share the construction techniques and encourage the recycled materials usage and do it yourself light structures. A direct interaction is also encouraged through the use and spread of urban farming in a joined effort to push Torre Baro into the Self-Sufficient neighbourhood of Barcelona. The active skin is now providing more than enough energy to sustain itself. The goal is for the active skin to act as a productive parasite in empty lots and unused spaces to increase the surface of energy production in order to provide enough to sustain the entire neighbour- hood. An important point is the usage of the organic photovoltaics that not only support the sustainability of the neigh- bourhood but can also provide a good topic of research within the Atmo and the neighbourhood.

Studio Work ATMO - IAAC Torre Barò Self-Sufficient District Competition
As part of the Self Sufficient neighborhood project the City Council of Barcelona invited the Design and Architecture Schools of Barcelona to participate in a competition for the design of a Self-Sufficient Neighborhood in Torre Bar贸. In particular the schools were given 2 plots of land in which to design a Self-Sufficient house prototype as well as a productive public space. Our proposal was that of a Self-Sufficient house and productive land, focusing on 3 main aspects: The use of 100% local materials for its construction, considering these local materials as coming from Colllserola park (wool, woods and local plants) The energetic self-sufficiency based on one side on the reduction of the electric consumption (thanks to passive or more efficient systems) and on the other side on the self-production of the energy needed. Social activation, proposing the development of activities and environments that are able to offer a service to the community as well as to enhance its identity. The House is than articulated in: WOODEN STRUCTURE, LIGHTWEIGHT VOLUMES, WOOLEN SKIN, ACTIVE SKIN , CLIMATIC SYSTEM (three different thermal zones).

Studio Work NUBULAR Magazzini Generali_Verona
This project comes from the social and urban study of Verona city. The most significant and emerging element is the “discontinuity”. A discontinuity between the two sides of Verona, North and South due to the train station and within Verona Sud due to urban voids generated by the old industrial areas. The theme of industrial memory is another important element.Despite being linked to its production history that has generated its urban morphology, Verona South does not recognize itself, missing of social identity. Re-establish this identity through the elements of industrial archeology memory, retrieve continuity with the historiccenter and within the same area, these are the goals of our project. To achieve these objectives, we applied the following strategy. - The River Continuum Concept, biological concept and continuous system which is to unite River and Channel, unifying the two Verona (North and South). The upgrading of the community identification points , such as interactive squares, connected to river, where citizens can take advantage of the relax, recreational and work areas. Each square of the Sistem Park has a network of pedestrian and cycle paths, all connected with places of identity of the different neighborhoods. - Finally, do of “Piazza della Rotonda” the center of the new district “Magazzini”, as well as a pole of attraction for the whole city physically connected with the “Station Bridge.” All in the name of the discovery of natural and cultural heritage of Verona (South).

Studio Work Self-Sufficient Building_Final Project KATA Project Retrofitting Mongolia
The KATA project is a direct response to pressing issues of Methane Release, harshening climatic conditions and scarce life resources for nomads in Mongolia. Almost half of Mongolia’s 3 million population are migrating nomads, that move to a new location seasonally once the soil of current settlement was depleted of its natural resources. The rapidly worsening environmental conditions have drastically reduced the chances of finding a new favourable for living land at once, thus forcing nomads to abandon historically formed customs of living in the wild and move to the peripheries of polluted cities in hopes of finding means for survival. What neither the suffering nomads nor the moderately content city dwellers are aware of are the effects that Global Warming has on their entire existence and not only convenience of daily life. The gigantic silent atomic bomb that our planet has yet to become aware of is residing under the vast lands of the most breathtaking valleys and mountains of Mongolia: the Methane Bomb. A deep layer of frozen biomass, permafrost, has been releasing unimaginably large quantity of methane gas into the atmosphere, putting our population in danger due to its flammable and explosive characteristics. If addressed immediately, this problem might be alleviated and furthermore, turned into a source of seemingly endless source of renewable energy. The KATA Initiative is a comprehensive response to the Methane crises currently riveting Mongolian lands. The main pillars of KATA are: - Tree. Utilizing the biorhythmic processes of nature we propose to capture methane gas that trees output into the atmosphere regularly and use it as clean burning energy source. - Fabric. Custom designed zeolite enriched nano fabric will serve as a shield between the methane released from the trees and the atmosphere. The fabric encapsulates the tree crown and serves as a collector for methane particles. - B-Drone. To eliminate the need for pipes we designed a self-sustainable gas carrier, that will take methane gas from the point of inception to one of the proposed destinations. - Airport. Serves as an underground energy capacitor. Its porous structural walls are embedded with zeolites, thus can store transported molecules of methane for significant amount of time. - Research center. An innovation and development hub that explores future expansion possibilities of KATA, as well as conducts experiments on methane purification and showcases the alternative ways of energy production to the local nomadic communities.

Water Related Works THESIS HYDRO-MEDIATING INTERFACE water management in contaminated grandwater sources
“Nothing is constant but chancge! All existence is a perpetual flux of ‘being and becoming!’ That is the broad lesson of the evolution of the world.” Ernst Haeckel
“…the form of an object is a ‘diagram of forces’....” D’Arcy Wentworth Thompson
“…form is only a snapshot view of transition…” Henri Bergson
Hidro-mediating Interface is a spatialization of an innovative, low-tech water desalination process. The goal is to reveal new technologies but not for the sake of the image of technology itself. The project is instead focused on generating technological ambience. The division between technology and culture - and building technology and architecture - begin to dissolve into a hybrid spatial sensibility. Fluid flows, structural patterning and lighting are all combine into a coherent whole, generating an unexpectedly vivid atmosphere. Recently, a re-examination of existing seawater greenhouse technologies has revealed possibilities for gradients scales, sustainable desalination using deep seawater and warm sea laminar water in an evaporation-condensation loop. The project is a landscape greenhouse-canopia characterized by two performative pattern logics. The first is a three dimentional meshwork of capillaries within which cold seawater (from a local deep source) is circulated in loop. The second is a series of vascular flow intaken, which direct warm sea water (surface layer) over the capillaries. Seawater is sprayed into specific areas, the so called vacuoles, this warm air as it enters, increasing its water content. The trasparent lenses creates additional heat in the sub-interior space, allowing the air to take on even more airborne moinsture. Then, when this super-humidified air comes into contact with the chilled micro-pipes, it condensates. The condensate - distilled - drips down the capillaries into pleated troughs below, which lead to seasonal storage tanks. The hydronic and structural processes will be legible, but in an ambient, atmospheric way. The aim is not the creation of a “mechanical landmark”, but rather the creation of natural interactive space defined by crossovers of technology, culture, and metabolic behaviours.

Water Related Works The HIDRA Project water project for S.ol.co. Onlus in Guinea Bissau
GOALS AND PROJECT LOCATION The HIDRA Project will start from the Hospital do Povo, project from 2010 by S.ol.co Onlus, in the village of IngorĂŠ (Guinea-Bissau). Over these years the hospital has become not only a center of care, but a reference point for the community. However, the lack of safe drinking water have influenced and continue to adversely affect performance and future developments. The Hidra Project propose a practical and modular solution to address the problem of availability of running water in the hospital, with a focus on the following objectives: - identification and promotion of local resources and technical skills; - community knowledge enhancement through user training. MISSION The Hydra project was elaborated with a plan of execution of two years. It begins with the collection of necessary funds and ends with the construction and installation of the modules. An important part of the Hidra Project will be targeted to the IngorĂŠ community involvement, through the teaching of construction process using local materials and local craftsmanship techniques. THE DEVICE [2014] the hidra module is made of localy sources materials, and filters contaminated well water using passive energy. This is done by evaporating contaminaed water, and collecting the condensed water vapour using a sloped roof. this system produces salt residue and pure water, ready for use in the hospital. sunlight speeds up the production of clean water, and it is collected in cisterns below the surface of the ground, for long term storage. During the rainy season, the sloped roof of the Hidra module collects rainwater and filters it using a locally produced ceramic filter, removing harmful bacteria. Using multiple storage tanks will reduce the risk of contamination, and ensure water availability when needed for use by the community. FIRST SITE VISIT AND COMMENTS [2015] From the meeting with the doctors and employees, plus the preliminary report on the state of the hospital and other S.ol.co related projects, we can confirm that the vision of the Hidra Project is expanding. It appears that it can take a number of branches of interventions not only on water, theme that seems not the only priority, but also in Bottom-Up micro-projects; Collaboration with local specialists; Training; Education; Sustainable and micro-economy ; Local (multi)culture; all focused in the idea of starting a local regenerative systems. 94
