RESIDENTIAL ECOLOGY
micro unit, multi-use megastructure
LIVING AND LEARNING concept, this multi-use residential design attempts to bring an immersive experience to its users, surrounding them in a multi-disciplined learning network and community. bringing new interpretation of learning environments, the design encourages both the residents and the incoming public users to LEARN about LIVING in a sustainable, communal, and more ecological way by having them learn through utilizing a
practice and act as an example to onlookers in how to lead a more sustainable life. the project began looking at tiny house designs and how they are able to
establish minimal private space while keeping larger shared public space between units, where the majority of the residents would spend their time. this would
not only encourage people to share resources but also allow people to learn from the different lifestyles surrounding them, creating an ecology of residents and users.

shared recreational space within unit network
this design focuses on the public/private spatial divide through the use of tiny units
connected through a network of occupiable flat areas and ramps. it also intermixes public programs throughout the unit structure in the form of greenhouses and public garden plots to bring another spectrum of public users into the residential ecology.

the housing and green housing units are affixed to the top of public learning
facilities and are traversed similarly to natural landscapes. the navigation process
is approached in an adventurous way to bring different parties together, comparable to how cities with smaller block structure allow people to have more options in navigating from point A to point

SYMMETRY SENTIENCE responsive kinetic canopy
timekeeping appendage prototype_1 week design duration initiated through the revisitation of gestalt’s principles and the
analysis of movement in various organisms, a general trend of open and closed stature was found in response to different organism’s comfort levels. this led to a module that could exhibit flexure between these
two states through angular compression to play on the comfort levels of the canopy user.
the canopy’s placement held high visual accessability from a wide range of spaces within the site so it was designed to be influenced by
fluctuations of light throughout the day, so that the structure would behave as a timekeeping device.
the aim is to challenge the phenomenon of perceptual
constancy through moving transparent forms and immaterial shapes. simulations and graphic projections were formed through the use of parametric software including, grasshopper for rhinoceros,
processing (open source scripting platform), and arduino (open source electronic platform).

Interior Rendering
simulation perspective, processing software
the individual appendages consists of a strip of material with control points on either side that are
connected with a string. as the string is pulled, the strip is gradually collapsed into a spiral. the direction of movement depends on the side that compression is applied to and the curvature depends on the spacing
of joints. a softened representation of this movement can be seen in the below images progressing from and absolute inner state
[1] to an absolute outer state [4].
in terms of the overall movement pattern, our goal was to create a dynamic wave that would progress
through the structure. using a series of camshaft gears, we introduced delay and rotation reversal in the canopy’s motion. [1]

SYMMETRY SENTIENCE responsive kinetic canopy
flexion prototype, fabrication
:: 1 week
the ability to detect human presence via arduino distance sensors triggers the actuators that
rotate and move the triangulated pieces of the canopy. a strategic arrangement of the triangles position in relation to the length of their hanging strings creates an intricate choreography of lighting effects that are visible by the sunrays during the day or the artificial lighting of the
LEDs during the night.
stats: 4m in length and 1m in width. structure consistes of 1 “mega” brain using arduino software, 2 massive rotary actuators, 72 metal flywheels, 120 transparent kinetic units, 300m of wiring, and 480 connecting knots, and 8 meters of LEDs. installed at AKTO college of art

B3OCC PAVILION
optimized composite colonnade
- 2nd place finalist
the redesign of the grandstands in philadelphia focuses on creating a space that can be utilized during crew race season as well as the off-season. it must function as
REGULATED STADIUM SEATING and
support spontaneous activity that occurs along the schuylkill river. this design accommodates over seven hundred spectators for events and spatial comfort for small groups and individuals alike. at ground level an oscillating path flows through the pavilion, inviting in travelers for momentary leisure, from which long spans of seating rise from the ground like oars breaking the water’s surface. overhead floats a deck propped up by
A CANOPY OF WOVEN COLUMNS that supports groups of sightseers overlooking the water.
the semi-transparent quality of the webbed columns also allows ambient lighting and wind to fill the space they create. this structure is accomplished by the innovative utilization of fiber reinforced plastics
(frp),
fabricated in such a fashion as to make the impossible come to fruition. at night the columns give off a faint blue glow that radiates due to a phosphorescent additive that collects the sun’s rays for nighttime release. he glow fades from the columns well into the night, encouraging those who are still out to begin their journey home, only to return again the next day to the fairmount park

return load values were received for each segment of our analyzed geometry which were then translated into an attractor map. this map would influence digital vector grouping throughout our designed form to create a structure that utilizes minimal material use while

fiberglass could wrap around and create a thickened web skin. a simplified
PULTRUSION TECHNIQUE USING RECYCLED WATER BOTTLES was used in applying the resin
to the fiberglass. by filling the bottles with the catalyzed resin, fiberglass strands were pulled through the liquid and through a small opening in the bottle cap that would control the ratio of resin to fiberglass. the fibers were then wrapped around the mold in overlapping patterns to systematically build the strongest system we could with minimal material use. after the wrapping and curing process is complete, the metal screws can easily be drilled out and the planes can be simply pushed out of either end that remain open. the mold and screws can easily be reassembled to repeat the process,

the weight of the structure is
IMMENSELY LIGHT in comparison to the wood or steel needed
to support the dead or live loads overhead. with very little material, it can withstand loads many times its weight by focusing on distribution of the loads through the outer skin of the column and secures the columns form, making it more structural. the lightness of using the composite material translates into the material cost of building this system. potentially
THOUSANDS OF DOLLARS CAN BE SAVED using this material in opposition to other
structural materials such as wood or steel. twisting up from the ground and spreading like an open hand, the form of the columns and the interwoven nature of the composite create counterparts.
