THE FLOATING MOON Sustainable Tsunami Resilient Landscape

IFLA Design Competition | 2016 | Spring Teammate with Hui Yang, Bin Yan, Yue Yu, Siying Wang

This project is an investigation of new prototypes of disaster-resistant landscape in Solomon Islands, which is under the risk of tsunami and sea level rise. This project proposes a floating intervention to mitigate the tsunami waves while provides self-sufficient agricultural land and mangrove habitat.

The design’s form derives from the acoustic wedges, which can significantly absorb the sound waves because of their shapes. By calculating the ability to resist shock waves among different methods of connection, the moon shape was chosen with additional contribution to fishing, farming, disaster protection and ecology.

Auki city is under serious risk of hurricanes as well because of the location near the equator where wind and ocean current change their directions.

Plan of floating island system

Since Auki has always been suffering from lacking of land, edges also act as boundary, defining four different functions of floating islands: Intertidal area that recreates Mangrove habitat, farmland, marine aquaculture and offshore temporal refuge. Sea water desalinated at the bottom of each wedge and transferred to the island to serve irrigation or human activities. Fallen leaves and stems from farm and mangrove habitat are ideal fish feed, while organic waste from fish farm and refugee can be decomposed and used as fertilizer for farmland and mangrove habitat. These four functions together create a selfsufficient unit of floating island system.



Tsunami Imitation

When there are no barriers or protections on the surface, the amplitude of waves tends to be higher by natural forces such as earthquake waves and hurricanes.

Wedge Protection

Because of the damping effects by the wedge structures floating on the surface and the elastic connections, the amplitude is suppressed and chaotic thus less subversive.



Acoustic Wedge

Vibration and Energy Absorbing When two wedges are putting besides each other, the concave shape will absorb the waves which are mitigated by the movement of the wedges and water.

Momentum Offset The mutual movement of the wedges will be offset because of the irregular placement of wedges which will vibrate in different directions when hit by waves.

Dumping Connections The seaweed will connect the wedges with the shallow sea beds and will works as flexible dumping connections to mitigate the shock waves and wedges’ movement.

A CRYSTALLINE FUNERAL A 10,000 year maker system for nuclear waste isolation pilot plant in Carlsbad, NM

Landscape Architecture Studio | 2017 | Teammate with Bin Yan Runner-up (Second Award) of International Idea Competition organized by Arch Out Loud

How can an isolated landmark reveal itself as a coffin to seal the radioactive nuclear wastes, and how can the crystalline funeral, reveal and warn the considerable influence of human power to the future generation throughout the 10,000 duration of decay of nuclear substance, and probably, the human being as well?

Salt crystal, which constantly seals the nuclear substance underground, will be regarded as a metaphoric connection between the funerals on the ground and the ones under it. Extra salt crystals in or around the site will be collected to build series of crystalline coffins, to seal the extinct species, one for each year, an ongoing funeral which lasts for 10,000 years, when the central church seals the last human being‌

THE STORY OF WATER Commercial Landscape Design for Hua Lian Supermarket

Landscape Architecture Studio | 2014 | Fall Design with Yue Yu, Le Dong | Include individual revised part only Site Location: Wu Dao Kou, Beijing, China

This is a busy site next to a subway station, with a large retail center defining its north boundary. This project is exploring how to maximize activity space while solving the stormwater problem. Our solotion is to fit different activities into an undulating topography.

The form of activity spaces came from the drop. Following the slope, rain water enter the bioswale and finally go into the retention basin —— the central lawn, which is the low point of the site.

THE PLATES Rebuilding Suburban Texture of Paris

International BIM Design Contest | 2017 | Spring Teammate with Bin Yan | Site Location: Saint Prix, Paris, France

This design is trying to explore a prevailing but significant question: how can we change a suburban segregated and monotonous area to an open and comfortable, nature-closed living environment? Considering the loose subruban texture, we designed a lifted platform for an open first floor space. Meanwhile, its roof gardens provide the residents with relatively private green space—— much-needed distance from the activities in the first floor.

The curved form of the buildings is meant to preserve the existing canopy trees to the greatest extent on the one hand, and to create a new suburban texture with fluent and flexible form language and space quality on the other. The staggered floors generate fluent and diverse communicating space for residences.

REDEFINE HORIZONTAL LANDSCAPE Landscape proposal for Dunn Ranch Prairie, Missouri

Landscape Architecture Studio | 2017 | Spring Part I individual, Part II Teammate with Nona Davitaia, Rui Zou, Shuailin Wu Site Location: Dunn Ranch Prairie, Missouri, U.S.

The Nature Conservancy is expanding their research program in Dunn Ranch Prairie, Missouri. The goal of this studio was to propose a new research station for about 20 researchers' accommodation, together with some on site structures for observation.

Impressed by the undulant landscape of the prairie, I expected proposing anything vertical would be apprealling in such a horizontal background.

Started from the constitution, a single pole can be understand as a marker, a row of poles in close distance act as a wall, taking some poles out from the row would get a gate... By understanding pole as the basic component of different landscape elements, different space and experience was defined.

Perspective of the main research station Located at the center of the prairie, the main research station is designed to be a self-sufficient building to avoid further disturbance to the prairie ecosystem. The poles in the first part of the proposal now act as vortex wind turbines, generating electricity for the building. Rain water is collected and purified by wetland systems, roof garden provides seasonal vegetables and fruits as basic food resources.

Perspective of Vortex Wind Turbines 289 vortex wind turbines together with 255 solar panels attached to mobile research labs can generate energy for 20 researchers's work and the operation of the main research station. It's windy from late Spring to early Summer and late Autumn to early Winter, so the extra energy of these months will be stored for those months that don't have enough wind.

THE LANDSCAPE OF WASTE Ecological solution from quarry to landfill for I & M canal towns Landscape Architecture Studio | 2016 | Fall Teammate with Yuhan Zhang, include individual part only Site Location: Lockport, Illinois, U.S. St Louis ASLA Chapter student Honor Award

The project focus on the excavated quarries in hinterlands of Chicago —— canal towns, which are now the common sites for landflls. Although these quarries have been flled with waste, the wound caused by human disturbance can never be healed, as a landfll can cause several kinds of environmental pollution. To move in a more just direction, this project come up with two projections: making Chicagoans more aware of garbage production and proposing a new form and process of landfll to reduce pollution. Facing the problem of landfll and waste, we cannot resolve the consequences of consumption, but we can show how our consumption has permanent consequences to these overlapped landscapes.

THE FOLDING INFORMALITY Rebuild the Tian'an Men Square ELOVO Skyscraper Design Competition | 2017 | Teammate with Bin Yan

We believe that people will live alternatively in future cities to maximize the spatial capacity and efficiency to sustain the vast population. Therefore, the question for us, the designers and builders of the future city, is to think about the new architecture prototypes which contribute to the alternation while maintain the quality and humanity of life, especially for the minority who reverse days and nights working for us.

Infilled with the concept of folding, both spatially and chronologically, the new skyscraper will be a compensation for the losing shanty houses and informal neighborhoods in Beijing. We choose the Tiananmen Square as our site not only because of its political and symbolic particularity, but also for the adjacency to the working place of most night workers. These units are landed into the underground space during the day time, retaining the political function of the square while providing green space with rooftop gardens for the bare ground. During the night time, these units adjust their position and unfold themselves into a highsense informal city. This strategy of spatial alternation and transformation, retain the multi-functional quality, both public space and high-density housing in this project, and protect those groups of people from being disturbed in the urbanization and gentrification process.

36

37

The Folding Informal City The folding and unfolding process of the architecture enables the alternative use of urban space, or even the dimensional transition between different users.

It is enabled by a movable structure system and modular spacing strategy which synthesizes high density housing, expandable circulation system and necessary open space. We do not value segregation, no matter as a political square, an informal city, or underground green space, by integrating them together, we want to make them visible, functional, and interactive, this is also how the concept of “folding� is interpreted in this project.

38

The ground glass panels make the underground roof garden visible, and can be rolled down for the movement of the building units and the transformation of the vertical informal city during the night time.

P L AY W I T H T H E A R T About fishing: the tragedy of common Landscape Architecture Studio | 2018 Spring

Rules of the first round - 10 of you are invited to “fish” in the “sea”. You can fish 15 times in total. Please have one piece of paper and a pencil in your hand.

- Each time, use your finger to pick one of the squares to select your “fish”. Then flip it and see the points on the back. You write down the points, at the end of the game you will have 15 numbers (or less, see 3) and sum them up, that would be your final grade. People who get the highest grade will win the game.

- If during the game, all of the squares were taken and there’s no more left, the game will end.

- Remember to put a √ on the “fish” you have taken so you won’t select it again.

Rules of the second round - 10 of you are invited to “fish” in the “sea”. You can fish 15 times in total. Please have one piece of paper and a pencil in your hand.

- Each time, use your finger to pick one of the squares to select your “fish”. Then flip it and see the points on the back. You write down the points, at the end of the game you will have 15 numbers and sum them up, that would be your final grade.

People who get the highest grade will win the game.

- When you flip your fish, if you see the red paint below, put a 0 on your paper. That’s a reserved fish.

You can not take any fish from the red reserved area.

- Fish as much as you can, if there’s no more fish outside of the red reserved area left, then everyone entered the moratorium season. You will need to put five 0 on your paper, it means you give up some of your fishing profit to wait for the recovery of fish.

- After the fishing off season, you can fish but you should only take the fish in blue paint area.

- Remember to put a √ on the “fish” you have taken so you won’t select it again.

42

Studio was playing with the installation For the first round, before fishing 10 times all the "fish" was checked, which means reaching the capacity of nature. For the second round, a fishing reserve area was added at the middle of the "pond", with the propose of moratorium season, "the tragedy of common" was avoided.

CHICAGO BIKE CRASH and LANDMARK DISTRICT MAP A guide for bicyclists to explore Chicago

After starting the DIVVY project, Chicago is one of the city that running the bike sharing programs. However, the increasing amount of bicyclists requires the update of urban transportation systems that can provide bicyclists a safer place to ride. The map shows the place where it’s more likely for bike crash to happen. Overlapped with the Chicago landmark district layer, the map is made especially for visitors——those who are new to the city and not very familiar to the transportation condition of Chicago——to safely explore the city by bike.

To look more into the map we can find the strip with most dark red that point out from downtown to the northwest, that’s Milwaukee Ave. After the government realized this is the most dangerous road for bicyclist, they proposed a bike lane here.
