If we draw a cloudy atlas for the Meadowland, is it both retrospective and prospective? When winds blow through Barrow, can we share a shelter with tundra above the permafrost? With fire ants connecting together in storm, drifting alone, is there a prototype of common conciousness already given? My name is Han Yu. I value curiosity, empathy, and creativity. I explore puzzles through design.

"OUR LIFE IS NOT OUR OWN, FROM THE WOMB TO TOMB, WE ARE BOUND TO OTHERS, AND BY EACH CRIME, AND EACH KINDNESS, WILL DETERMINE OUR FUTURE REBIRTH." * Sonmi, "Cloud Atlas"

RITUAL REMEDIATION A Cloudy Atlas Of Community Generated Futures The speculative atlas is an open-sourced guide to an uncertain future. It is the catalyst for grass-roots action and the progenitor of a new resonance. The Meadowland is a sinuous park, one that supports infinite moments of â&#x20AC;&#x2DC;impermanence and multiplicity,â&#x20AC;&#x2122; it is continuously made and remade by the lives, materials, and stories that create the physical and ephemeral social infrastructure of communities that occupy it. The atlas is intended to sustain, prolong, and provoke this social infrastructure through a series of phases and designed interventions, catalyzing community action and imagination. We argue that resiliency and adaptation in the face of climate change cannot be accomplished without the imagination of the communities affected. As the result of our initial provocations, we offer you a cloudy atlas of community generated futures, embedded in the material histories of the area. This atlas serves as a road map of possibilities by which communities, designers, governments, and institutions can navigate the unpredictable future in real time. Sea level is the datum by which ritual is organized around, not inhibited by. Through distinct insertions and ambiguous provocations about life in the future Meadowland, we encourage community members to fill in the blanks, writing and enacting their own stories based on our initial excitation. Unfolding in small moments or over decades, these interventions generate a proliferation of futures for the Meadowland, grown in the generative incubator of rich community dialogue, housed in mascots, prophecies, landmarks, and legends, and engaged with through the practice of everyday rituals.

Kelly Katie, Kirk Gordon Programs are done through close cooperation. I took the lead on the concept and structure of cloud atlas, as well as scenario collages.

Our project offers a collaborative and iterative community-oriented design process that emphasizes, exaggerates, and re-contextualizes the shared meanings of local material artifacts to: • Foster and enrich collective identity • Provide foundations for empowered remembrance and transition • Catalyze imaginative speculation + experiment regarding potential futures

EROSION

The convergence of fluvial and tidal currents creates an area pf dynamic flows that crash and calm, slip around, and grind past one another. Difference in salinity creates different conditions of density and capabilities to carry particles. The movement of these various flows along the borders of wind and soil create high energy conditions that can launch particles into far reaches of the system.

Shear stress and frictions factors along shores, soil beds, and water surfaces create high energy moments that transport coarse bedloads and disrupt consolidated sediments. The movement and intensity of flows dictates the ability to carve shorelines and shape bed formation. In the fluvial shores erode into meanders, transporting sediment into the estuary and marine environment.

Accumulation is a key aspect of land and bedform creation in the estuarine environment, and where particles deposit can have significant effects on the environmental health of that area. Stronger currents keep small particles in suspension, depositing only coarse material. In other areas, like where tidal and fluvial currents meet, conditions of slowed energy are created allowing settlement velocities to deposit sediment in the area.

In two days we explored the Meadowland through experiments, interviews, and documentation. Field experiments involved material explorations on six sites, testing water through chromatography. With observations drawn from experiments and residents interviews, we started to develop preliminary intervention strategies, explore how these interventions affect each other in time.

Imagine the atlas as a book. With these interconnected story lines, we can begin to portrait chapters. Each chapter has its own goals and themes. Residents, scholars, and community partners will all participate in the creation of stories and chapters.

â&#x20AC;&#x153;WE USED TO BUILD OUR HOUSES UNDERGROUND AND BURY PEOPLE IN THE SKY. NOW WE DO OPPOSITE THINGS AND HAVE BEEN COLD..." * Jack Heber, Cold Climate Housing Research Center

FULL SPECTRUM SYMBIOSIS Arctic Building-Ground Interface Strategy As the north-most tip of United States, Barrow exhibits an extreme geology-meteorology condition. At high latitudes, low average radiation in limited light time throughout the year, as well as continuous permafrost layer, contribute to the specific cold moist climate regime across the area. Low biodiversity makes the ecosystem even more fragile. Based on the homogeneous topography, human construction makes it possible for the environmental conditions to change without obvious natural ground relief. Intentionally or not, road grid and building structure deeply reshaped the radiation distribution and air flow pattern within the settlement. However, mutual beneficial relationship hasnâ&#x20AC;&#x2122;t been observed from the lifted building structure subsided in the melted active layer. Interim space between building and ground becomes the most problematic area across the city, which could also be viewed as the breakthrough point to redefine the relationship between environment, human and species. With carefully designed form, function and transparency of building-ground interface, micro-climate mode, as well as spatial configuration could be re-programmed according to specific site features. Varied typologies created from a spectrum of demand and limitation may weave a new socio-environmental matrix, within which human and other species could make a step forward toward a symbiosis relationship.

â&#x20AC;&#x153; AROUND 100 ANTS ARE NEEDED TO BEGIN TO FORM A RAFT, AND IN THE WILD, THE STRUCTURES CAN FLOAT ALONG FOR WEEKS OR EVEN MONTHS...." * Fiona Macrae, "The Daily Mail"

EVOLVING COMMON CONSCIOUSNESS In An Ant's' Eye: Dr. Lambeth & His Stadium Reading the space from a hydrological perspective, Lambeth Field exhibits characteristics of isolation, separation, and fragmentation under the influences of cumulative anthropocentric environmental modifications. Realizing that, I tried to find different coexistence strategies from other species. The unique behavior of fire ants forming floating rafts by linking their bodies together during flood shows a completely different living philosophy: by sharing consciousness not only between individuals but also with the environment, the whole system could be seen as a super-organism. Through this lens, Lambeth Field could also be seen as an organism gathering consciousness from all the species living in it, as well as the environment itself. To achieve this goal requires a composite design process. Veiled axes of the field are extracted and materialized by water gathering from the surrounding environment, forming a resilient scheme. Potential episodic scenarios â&#x20AC;&#x201D; construction of residence, growth of vegetation, reproduction of animals â&#x20AC;&#x201D; work as "islands" exerting influences onto the scheme, contribute to shape a primitive landform. After that, interactive events happening in the field would act as mediators between species and the environment. The field continuously evolves to stand for the interest of all participants. Inhabitants not only live with the environment in a more harmonious way, but have a chance to better understand the wise of nature.

"GROWTH, DEATH, IRREGULARITY, AND REGENERATION COMPLIMENT THE SPACE, RATHER THAN DETRACT FROM IT.." * Gena Wirth, SCAPE

INTERNSHIP WORKS Free Forest Park | Venice Biennale Pavilion The Rees Street Park competition is the main project I participated during my internship in SCAPE. We started with analyzing Toronto's geological structure and ecological histories. In this process, we realized how ravine system has shaped the hydrological characteristics as well as basic urban configurations of Toronto. Above such structure, the forest is deeply intertwined with its cultural history and still plays an active role in urban life today. Inspired by the history of southern Ontario deciduous forests and their human interactions, we tried to propose a free forest on the site, Rees Street Park in downtown Toronto. We imagine it as "a place equally for trees and for people, evokes a new cultural identity of stewardship and inclusion along the waterfront."(Gena Wirth, competition proposal) To achieve this goal, we introduced various programs into the park, used wood material for fences, benches, and bonfire. All these elements are embedded in interactive activities that change through a year. We hope the park could evolve to meet the needs of citizens. Another major project I participate in is the design for the Venice Biennale Pavilion. I'm mainly involved in the plan iteration, digital / physical model construction, and perspective renderings.
