01 AIR OPS A RETROACTIVE PLATFORM FOR ENERGY EXCHANGE Masters Thesis with Distinction Advisor: Eric HÜweler Fall 2012 Just a few months ago, Hurricane Sandy tore a path of destruction through the North East. In some ways, it was an event that revealed the fragile nature of the city’s electrical and mechanical infrastructures. It raises the question: how can we create a certain level of individual energy autonomy, while simultaneously increasing the robustness of our existing energy infrastructure? One possibility is to look at the potential of an infrastructure that operates between the scale of the parcel and the scale of the city - a local, block scale system that can retroactively integrate with multiple existing buildings. Air Ops is a proposal that speculates on the possibility of such an infrastructure, and the necessary framework required to realize such an ambitious endeavor. A careful investigation into - and subsequent re-imagining of - the NYC zoning codes becomes the critical method that enables a systemic transformation of the intertwined value between zoning and energy-use in a post-Hurricane Sandy Manhattan. The most fundamental idea of the project hinges on the notion that zoning has been, and remains, one of the most potent elements in shaping the future course of the city, and in order for architecture to tackle the problem of energy at the scale of the city, especially as a response to the increasing volatility of the climate, it must bring topics of sourcing and using energy into active dialogue with zoning, real estate, and the public realm.

Zoning Illustrated Hugh Ferriss famously rendered into life the first zoning code in his charcoal and pencil images, which has since become a visual guideline - or even, the standard aesthetic of the maximum envelope that would shape much of the NYC skyline for the coming century.

Inverting the Paradigm This new urban typology essentially volumetrically inverts this paradigm: the top surface is maximized for sustainable energy collection, and the setback is then cut from the underside of the volume to ensure access to light and air for buildings below

A New Horizontal Paradigm within Manhattan’s Verticality Although this new physical infrastructure may enter the imagination through a canon of previous works that similarly occupy the air, such as Yona Friedman’s Ville Spatiale, the key difference here is that this system is less about an autonomous or mass proliferation of a specific order, rather that it is a selective, even opportunistic system that seizes upon the coincident intersection of existing urban conditions. Ultimately, the building itself is but one manifestation of the framework; one could consider it a template upon which all future iterations may be built upon.


Re-Imagining Zoning In order to make this framework a reality, a new set of zoning provisions needs to be created to provide proper organizational and volumetric constraints. A new merged parcel ownership model enables individual owners to contribute air-rights potential, structural support, circulation access, or floor area, in exchange for compensation through a combination of renewable energy grants, tax credits, and on-site bonus FAR.

Function Overview Axonometric The final building size and massing inevitably becomes a direct result of the combination of the new setback regulations and economic pressures. Functionally it serves two purposes: first, to provide partial energy autonomy as an additional layer of redundancy in the grid. And secondly, it is an energy exchange platform that facilitates waste energy re-use between buildings.


The Potential of Bryant Park A group of parcels on the southern edge of Bryant Park was chosen as the ideal test scenario: the Midtown district was immediately compelling because of its general high density, and heterogeneity of both building heights and types. The presence of both the NYC Public Library and American Radiator Building tests the flexibility and adaptability of the infrastructure against historic landmarks.

Extending the Public Plane Air Ops’ adjacency to Bryant Park uniquely enables the project to engage and respond to issues of image, frontage, and public space brought about by this new platform. The rooftops of certain lower buildings are converted into publicly accessible terraces which results in a continuation of the public ground plane into the vertical axis, where both the public and private benefit in this new joint ownership effort.

02 BRIDGING AS URBAN INTERFACE COMMUNITY MASTERPLAN FOR MARACANÃ GSD Option Studio Instructor: Jorge Silvetti Spring 2011 Rio de Janeiro is a city on the verge of a rapid and massive urban transformation, evidenced by its hosting of the World Cup in 2014, and the Olympics in 2016. Yet urbanistically, the city still remains a series of fragmented an ill connected islands, severed in a large part by a rail corridor that cuts across the city. The site of focus is the Maracana district, the home of the largest stadium in Brazil, and also the site of a school, a large park, and the favela Mangeira. The design seeks to strategically use the bridge typology to infrastructually re-stitch these neighborhoods. This metaphorical and physical bridge weaves back and forth, constantly shifting its relationship to the city, becoming a series of programmatic elements including – a metro and train station, a library and career center, a community sports facility, and a sports museum. At the center of the project is the bridge structure spanning across the train tracks. By positioning it diagonally, and making it as thin as possible, it enables the structure to act as a façade communicating between the stadium and the favela. The thinness of the structure allows a great deal of transparency – allowing the activities of the individuals inside to become the façade, or the image, of this new connectivity.

01 A More Frequent Connectivity The existing opportunities for crossing the site are more than 1.5 miles apart - between the Mangueira pedestrian overpass and Sao Cristovao metro station. More opportunities to cross over increases accessibility.

02 Diagonally Contextual A diagonal connection across the rail links the university and the park axially, while referencing the favella and stadium elevationally. The ‘facade’ of the diagonal refers to and reflects the larger urban context.

03 Urban Interface The abandoned military site to the north of the rail has potential to be re-programmed into the public realm, becoming a collective interface between the favella, park, and stadium.

04 Bridge Anchorheads Although the physical act of bridging is the primary source of connectivity, it is crucial for existing programmatic anchors along the rail’s edge to re-appropriated and integrated into the bridging intervention.

Rio’s Rail Corridor: an Artery and a Wound Rio de Janeiro’s growth as a city relied on a series of rail corridors that extended from the city center. The railroad acts as main arteries, transporting people and supplies outwards, and growth followed these lines. However like any heavy infrastructure that cuts across the city, neighborhoods on opposite sides of the railroad become cut off from each other, a condition exacerbated by the sparse frequency of connections transversely across the rail corridor.

Maracan達 Masterplan & Site Sections As a whole, this winding snake like form is over 1km long, but this megaform never reads as a monolithic structure - rather, its shape and function adapts as necessary. The scheme manifests in a series of connected links that visually register as individual segments, differentiated in volume, orientation, and program.


Building Section A longitudinal section through the building reveals a level of transparency that enables unobstructed views from the hill of Mangueira to Maracana stadium.

Building Plans The bottom-levels of the bridge structure functions as a train concourse and pedestrian passway across the rail corridor. The upper levels consist of a university extension library and career center catering to favella Mangueira. 02 BRIDGING AS URBAN INTERFACE

Perceptual Analysis Visual lines are drawn from varying distances and heights to determine the amount of building that one can “see through�, as a quantitative metric for transparency.

The Ephemeral Thinness The further one moves away from the building, the more of an ephemeral quality it takes on, until the building seems to be merely a two dimensional grid imposed on the sky, animated by the activities of its own community.

Transverse Sections A series transverse cuts in the bridge structure reveal a mixture of functions and space sizes within the thin volume. 02 BRIDGING AS URBAN INTERFACE

03 INTERSECTION TACTICS A MUSEUM FOR AN INDUSTRIAL DESIGNER IN TOKYO GSD Option Studio Instructor: Neil Denari Fall 2010 This project delves deeply into issues of form + graphic, contextualized through a small design museum in Tokyo tailored for Japanese industrial designer Sori Yanagi. The design explorations centered on the rigorous manipulations of ellipsoidal geometry through scale, orientation, and intersection, bounded by rigid site perimeter. Through these techniques, light and space were modulated between soft and hard thresholds. The museum’s monolithic, concrete exterior is contrasted by the unexpected under belly of an entry, and several façade openings that reveal the softness of the interior. Furthermore, the spatial and perceptual sequence becomes a binary experience of moving and inhabiting the interior and exterior surface of ellipsoids that make up the floors and ceilings of interior spaces, reinforced through the shifting materiality from exposed concrete to a white surface finish. The tension between strict and playfulness, in addition to material and geometric transformations, attempts to reflect and celebrate the sculptural qualities found in Sori Yanagi’s own work.

Forma-graphics The central question of the studio was: how are form (3D) and the graphic (2D) engaged in a constant feedback loop? How can one give rise to the other, and vice versa? The traditional “japanese mon”, Sori Yanagi’s famous furniture pieces, and the “wabi-sabi” sensibilities of the japanese aesthetic were among the precedents in initiating discourse and the design process.

Geometric Genealogy This matrix describes all source geometries used in the construction of the project, organized by the function of the surface. The idealized form of the ellipsoids are obscure to the user as its true boundary extends far beyond the exterior building envelop. The user instead must gain greater implicit understanding of the nature of the geometries as he proceeds through the spatial experience.


Massing Overview The formal expression of the built object is simultaneously restrained and quirky. It sits on the site with an underbelly that eccentuates a sort of destabilizing unfamiliarity. Each elevation is bare except for a lone, asymmetric aperture, which creates and completes a distinct graphic identity for each face of the building.

Concrete Monolith Aside from the articulation in the underbelly and lone aperture, each facade is adorned only by the pattern of concrete panel formwork


Ellipsoidal Surface Intersections Study model exploring the generating ellipsoids required (represented in wireframe) to create occupiable surfaces that represent floors, walls, etc.

Geometric Algorithms An early geometric exploration focused on the mathematical properties of the ‘super-ellipse’, a specific geometry created through a single set of parametric functions that allows for a smooth modulation between several geometric states one of which is that of a “squircle”, a geometry between a square and circle.

Parametric Functions: x(u, v) = A * c(v, 2/t) * c(u, 2/r) y(u, v) = B * c(v, 2/t) * s(u, 2/r) z(u, v) = C * s(v, 2/t) Auxiliary Functions: c(w, m) = sgn(cos w) * |cos w|^m s(w, m) = sgn(sin w) * |sin w|^m -pi <= u < pi -pi/2 <= v <= pi/2

Soft vs. Hard Thresholds Articulating the edge, or boundary of a space takes on two possbilities - the first is normative - apertures created through the direct intersection subtracting a smaller volume from a larger one. In this instance, the edge is clearly defined. The second type is an intersection that requires an “invisible” third geometry that interrupts one surface while allowing the other to continue. The result creates a threshold that is has a soft transition between the occupiable and purely visual. The main exhibition floor is a space that formally reflects the sensibilities of Sori Yanagi’s own designs. The juxtaposition and play between hard and soft edges allows floor to flow into ceiling, interior to exterior.


Transverse Section The elevators, egress stairs, and MEP systems are all tucked into a thin vertical strip along the back edge of the site, so the rest of the footprint can be freed up for a pure geometric & spatial experience.

Longitudinal Section The spatial inversions in the experiential precession is clearly depicted in this section, as the visitor is constantly moving from a space on the â&#x20AC;&#x153;insideâ&#x20AC;? of an ellipsoid to a space on the outer shell of the same ellipsoid.

04 RECREATION IN THE CITY AN ATHLETIC FACILITY IN WILLETâ&#x20AC;&#x2122;S POINT NYC GSD Core Studio Instructor: Felipe Correa Spring 2010 The focus of this studio was dual-fold: first, to create an urban framework to revitalize the area of Willetâ&#x20AC;&#x2122;s Point, NYC - currently a derelict district of temporary auto-body shops, and second, strategically position a public recreation facility within the site as the primary catalyst for further urban renewal. The project is situated in a special zone in between La Guardia airport and JFKairport. The area is also the site of Citi Field, a baseball stadium. The primary mode of transportation to and from the site is vehicular, therefore the road infrastructure becomes a critical element in redening the district. Instead of weaving the special urban composition of the site back into the adjacent residential neighborhoods, the design augments the unique location by reconfiguring the site into a specialized development zone that serves the twin airports of New York. Within this framework, the recreation facility becomes a hub that provides culture and leisure to locals and travelers alike.

Road Infrastructure Analysis Initial analysis and breakdown of the roads types revealed that almost 40% of the roads (by length) were ramps and other transitional elements connecting the regional freeways to the local streets. Furthermore almost half of the roadways were elevated. It was clear that the infrastructural maze was created through decades of additive processes without regard for optimization. The first site strategy is then necessarily the minimizing and streamlining of the roadway infrastructure.

Cross Hybridization The recreational programs were separated from the community and support programs. Conceptually, each set of program was divided into parallel strips, which then becomes interwoven into the other programmatic set. The resulting intersections and courtyard voids becomes a hybrid space between recreational and community space. The twin parallel grains creates a spatial & processional sequence to which users can easily orient. 04 RECREATION IN THE CITY

Urban Icebergs The community and athletic complex manifests itself as a series of discrete volumes on the surface, in order to promote further urban development at a smaller, more porous scale. However, to truly accommodate the size requirements of the programs, these discrete volumes are connected in two levels of unified facilities below ground.

05 EMBEDDED LIVING URBAN STUDENT HOUSING IN HARVARD SQUARE GSD Core Studio Instructor: Nathaniel Belcher Fall 2009 The notion of collective housing was at the center of the challenge of the 3rd core studio. The positioning of the site in the center of Harvard Square business district became a catalyst for a new type of student dormitory, one which renounces the cloistered condition of a conventional â&#x20AC;&#x2DC;Harvard Houseâ&#x20AC;&#x2122;, and instead actively engages the city, and fosters social interaction across a variety of scales. An exterior, urban atrium invites the public to circulate up across the void, where various public programs were embedded among the dormitory programs. The public auditorium, gallery and tutoring center were all designed to enable students to give back to the city, through acting, making, and teaching. This void also becomes the through-passage way for people accessing the rest of the Ratcliffe campus. At the architectural scale, a series of smaller atriums form central voids for internal dorm clusters. Together, this system of voids become the primary organizational generators across the multiple scales of public and private.

An Urban Scale Intervention The project begins with an intervention at the urban scale, identifying the fragmentary nature of Harvardâ&#x20AC;&#x2122;s sub-campuses. The current Ratcliffe Yard campus area lacks the cohesiveness of the Harvard Yard area. Through a series of small scale interventions, a new sub-campus axis is created to give a new internal identity to the area. Anchoring the new axis is the location of the new dormitory, situated amidst Cambridge commercial life and at the center of the entire Harvard community as a whole.

06 POINT CLOUD KINETIC WEATHER INTERPRETER GSD Independent Project Instructors: Panagiotis Michalatos, Jesse Shapins, James Burns Spring 2012 Point Cloud is an attempt to reimagine our daily interaction with weather data. In todayâ&#x20AC;&#x2122;s data driven world, the nuances of weatherâ&#x20AC;&#x2122;s continuously shifting states are largely oversimplified as the information is transmitted into our daily experience. Our various home and mobile devices most likely distill a forecast into static representations, such as numeric values or simple infographics of sun, clouds, or rain. There is a deep discrepancy between the flatness of the visualizations we are accustomed to, and the rich mixture of tactility and perceptibility of our immediate physical experience. As a critical response to these issues, Point Cloud emerges as a sculptural form defined by a thin wire mesh, driven asynchronously by servos controlled via Arduino. As whiteness of the hanging structure begins to disappear into the background, the viewer is treated to a constantly morphing swarm of black points dancing through midair. Despite the fact that the only type of mechanical actuation is linear, the resulting motion is like that of a third degree digital surface; the effects each push and pull ripple out along the elastic tension of the wire threads, and in combination with the syncopated rhythm of the servos, create movement that is complex, unexpected, and hopefully wondrous.

A Layering of Discrete Components The various components of Point Cloud are functionally autonomous and clearly defined: 4 cables descend into a central control core, from which a lightweight steel space frame cantilevers and supports the 8 servos. Each servo powers a cam mechanism that activates 3 to 4 pistons that push and pull on various parts of the wire mesh - composed of over 300 feet of wire thread, and 966 intersection joints.

Schematic Drawings Plan, side, and front elevations of Point Cloud sculpture


The Heart of the Cloud The core module of Point Cloud consists of an Arduino UNO board and wifi module powered by a 9V battery. Initial instruction sets are transferred via the USB port on the Arduino, then data is streamed through wifi. Furthermore, the core includes a circuit board that connects the Arduino board and external 7V power with each of the eight individual servo modules.

Core, Structure and Shell Breakdown of component parts that make up the sculpture


Creating An Emergent Effect The combined actuation of 8 servo modules creates the undulating effect of point cloud. There are three types of configurations, with two end modules that have 4-pistons, and the remaining with 3-pistons. For each module, as the servo rotates, it takes turns extending one piston while retracting others. The result is that various parts of the external mesh would be displaced outwards while other parts are pull inwards.

07 MOON SEED LUNAR CULTURAL CENTER Sucker Punch Competition 1st Place Prize Winter 2011 Moon Seed is a speculative proposal that attempts to situate a Lunar Crater Cultural Center along a continuous timeline of human space development. This Lunar development is not the beginning, nor the final goal of humanityâ&#x20AC;&#x2122;s presence on the moon; it is merely a point-in-time of a perpetual, phased-project to expand human presence extra-terrestrially. The challenge of creating a cultural center on the moon is that it cannot exist independently, but rather it must co-exist with other programs already in place that can initiate and sustain inhabitation. Given the increase of privatized space ventures at the beginning of the 21st century, the proposed Lunar settlement would likely be a cooperation between government, scientific, and commercial enterprises. This proposal envisions that a permanent settlement on the moon is a byproduct of a joint venture between three agendas: resource extraction, scientific research and exploration, and lastly, inhabitation and the associated leisure and recreation. There also exists a larger, collective dream to transform the moonâ&#x20AC;&#x2122;s surface into an Earth-like environment, with a breathable atmosphere capable of sustaining life.

A Generative, Phased Infrastructure The proposal imagines the deployment of a large scale pod [MOON SEED] into the center of the crater site, a sort of infrastructural seed that contains everything that is needed to propogate a permanent lunar settlement. To achieve that end, SEED creates self sustaining energy with an integrated nuclear fusion reactor that runs on helium-3, an element more plentiful on the moon. The mining of raw lunar materials, along with the slow canibalization of SEEDâ&#x20AC;&#x2122;s internal megastructure and shell, provide the required material resources for the production and further build up of the programmatic space â&#x20AC;&#x201C; initially within the existing envelop of the shell, and eventually to independent lunar settlements along the perimeter of the crater. The final task of the SEED reactor is to gradually terraform the moon with its surplus energy generation. Over the course of 100 years, the deployment of hundreds of SEEDs will eventually create shallow lakes in the craters, and a thin but breathable atmosphere across the surface of the moon.

Culture, Evolved As the lunar settlement grows outward and the terraforming reaches a critical momentum, SEED gradually evolves from a critical piece of infrastructure to a monument and relic of its former function. SEEDâ&#x20AC;&#x2122;s final form is also a process of the slow erosion of its initial closed shell, through the self-consumption of its own structure and shell over time. It is through these transformations in both form and function that an object of culture begins to manifest. Rather than predetermining a particular cultural program within the project, the notion of culture becomes a temporal phenomenon, a resultant of all that has come to pass.

08 HANGZHOU RAFFLES CITY MIXED-USE DEVELOPMENT UNStudio 2008 - 2009 Raffles City Hangzhou is a mixed-use development in the Jianggan district of Hangzhou City. The site is located in the centre of the Qianjiang New Town area, and its close proximity to the Civic center, the cultural and commercial axes of the city, and direction connections to public transit generates a unique potential for it to become a multimodal hub for businessmen, visitors, and residents alike. RCH aims to become an “all-in-one” destination for work, live, leisure and entertainment. Three primary optimizations form the strategic design framework of the project: the views and visual relations to the surrounding, the economic model through internal program distribution and accessibility strategy, and finally an integrated experiential and spatial sequence within the architecture. The key to our urban design approach is to both capitalize on the site’s strategic placement, and to analyze the development with a mixed use concept. Operating also as a high rise development, the project commands panoramic views to the cultural district from the lower levels to the QianTang river from the upper levels. Urbanistically, its prime location also enjoys a high degree of visibility from the rest of the city, creating the potential to become a landmark and icon of the city.

Shading Panel Component Breakdown A wide variability of panels results from its continuous adaptation along a complex surface.

Variable Shading Performance Elevational shading percentages based on varying panel width and rotation

Individual Panel Parameter Variation Variables such as width, depth, rotation, and tilt were calculated computationally with custom scripts and the results were linked to an excel database for analysis and fine tuning.

Facade Panel-Type Zoning Analysis Facade shading panel parameters varied widely across the complex skin, therefore large striations along the envelop were defined as thresholds for the gradient transformation of the shading modules. This method minimizes the number of unique modules populating the facade.

09 THE MOIRE HANDBOOK LA BROAD MUSEUM Diller Scofidio + Renfro Summer 2012 The moiré pattern is an optical effect created through the interference of two patterns. For the Broad Museum elevator, a specific text moiré pattern is created through the superimposition of a layer of horizontal stripes and a layer of compressed, inverted text. The horizontal stripes are positioned on the exterior face of the glass walls of the elevator, the text on the interior of the elevator shaft; when the elevator ascends descends, the relative movement between the two layers creates an animated text effect. Since the text only becomes “legible” once the stripes are superimposed, an artist can strategically encode messages or text-based graphics and patterns that reveal themselves only when the stripes in the elevator cab temporarily pass through that specific position in the shaft. The objective of this booklet is to familiarize the reader with the mechanics of this effect, and make recommendations based on several variable constraints, including: scale, spacing, movement speed, viewing angles, contrast, color & lighting.

Relative Scales & Ratios The relative ratio between the stripes and the letters is critical in ensuring the proper legibility of the moirĂŠ effect. The scale ratio between all elements are strictly fixed, both the vertical spacing between stripes and between letters, as well as the relative scale between the stripe and letters.


Perceptual Effect A perceptual set of text - what you see as a full letter or word - is comprised of 6 stripes and 7 rows of text. Each gap between the stripes reveals a different 1/7th of text behind. Collectively they recombine and display, in reverse order, the intended letter.


Physical vs. Perceptual Movement There is a large discrepancy between the rate of physical movement of the letters (or the speed of the elevator), and the perceived scrolling of the constructed effect. For each unit of physical movement, the perceived letters move 7.35 units. This has to do with the nature of the construction of the perceived letters. The â&#x20AC;&#x2DC;resolutionâ&#x20AC;&#x2122;, or sizing, of the stripes directly reflect how fast the perceived letters move - each minimum unit of perceived movement can only be a little as the width of a stripe. The ramifications of this effect is that the rate of physical movement is severely limited, since legibility is lost once the perceived scrolling of letters becomes too rapid.

Context of Implementation The Moiré pattern is designed to be applied to the Broad Museum elevator. The cylindrical elevator cabin is fitted with 8-feet tall glass walls, and it travels 44-feet from the bottom of the ‘vault’, emerging into the ‘veil’ - the main gallery space. The stripes of the moiré pattern would be applied to the outer surface of the glass cabin walls, while the text pattern would be applied along the length of the shaft wall itself.

10 REEF PS1 / MOMA COMPETITION ENTRY IwamotoScott Architects Spring 2007 REEF seeks to create an environment for the MoMA/PS1 Urban Beach that is experientially aquatic. The proposal conceptually uses the underwater landscape of the reef to create an atmosphere of light, shadow, shade, and movement. The primary elements of the reef: sea floor, reef rocks, and coral / anemones - are translated into three corollary architectural elements - gravel sea bed, reef mounds, and anemone clouds. The proposal creates a column-free space to allow the anemone clouds to float over the courtyard. To achieve this structurally, they are suspended on lenticular cable trusses that span from the existing concrete walls. The cable placement is dependent both on where the walls are the strongest laterally, and to form an overall figure that wraps together with the strip of sea bed below. The reef mounds are situated on the sea bed relative to the clouds so that they create a range of atmospheric conditions for the user: shaded, sunny, misty, dry, and rainy.

Organizational Principles Like water, the flow of the site and program generates the pattern of structure and surface for the anemone clouds and reef mounds. The patterns align, and are registered through their respective constructional systems. The anemone clouds are made of 1200 uniquely shaped fabric mesh modules hung from light wooden spacers attached to the bottom chord of the cable trusses. Together, they form a porous tensile diaphragm where the individual fabric modules are designed to move with the wind.

A Canopy of Variable Function During the day, the canopy acts as a shading device from the summer sun. In the evenings it activates with undulating lights in conjunction with the Warm Up music events.


Prototyping the Canopy A scaled model tested the overall pattern of the module aggregation, while a 1:1 sectionsl prototype of the canopy tested the durability and flexibility of the module material, and construction connection details.
