GREEN RENOVATION Spring 2011 3rd year undergraduate studio, tutored by professor Alexandros This project started from two main concerns of high rise apartment located in the city: Isolation of neighbors in the apartments and contaminated air in the city. The main concept started from I-beam. Using ornamental I-beam as a functional element, it creates wind vibration power generators and interior public spaces. This renovated building uses air as power source and filters it to produce clean air into the interior space. After using air in the apartment, the filter system reabsorb the contaminated air to bubble, which is the facade of the interior public space. Because of the dirty air, after being reabsorbed, the bubble space turns to translucent and keeps residents privacy with plenty of lights.

Wind Vibrating Power Generator The thin lug units attached power generator produce electrocity as vibrating by winds. This innovative unit contributes not only eco-friendly energy, but also beautiful and mysterious looking from outside passengers’ view point.

Dirty Air to Clean Air There are five bubble spaces among the 26 stories building. These public spaces become lungs of the building and contribute clean air to each housing units in the apartment. Each bubble surrounding the public space is hollow and consists of transprent skin. After the bubbles absorb dirty air, it turns to translucent an nd it controls the amount of light in the sp pace. The residents living in this renovvated apartment share this space as community room and as filter by connected with each housing unit. So residents can see e the interaction between their living air

BREATHING DISTRICT Autumn 2011 4th year undergraduate studio, tutored by professor Bart Overly When designing residences, the main concern is not to harm the preserved environment on boundary of the site. For protecting the preserved space, the residences are only allowed to watch it. However, as extending the green area into the residences, residents not only have a good view but also are surrounded by refreshing environment to let them experience indirectly.

The circulations of the humans and cars are clearly seperated by different levels. The ground level only allow walking civilians, and there are two main layers under the ground level. The car circulation is about 10 feet below the ground level. And about 15 feet below the ground level, there are water circlulation running from lagoon into the site. The main purposes of the water path are filtering water and sustaining vegitation on the green spaces within the site.

Green Wave Complex All green connection with lobby space from each housing meet the wavy complex. The green roof of the complex produce habitat to birds. The punched holes on it are connected to water path so that it can contribute water to sustain the vegitation. Like the green ramp from housing, the wavy green roof is also preserved nature space. Residents can observe this birds’ habitat from the apartments and public park. Therefore, residents can feel that they are surrounded by preserved nature. And also the people approaching from the metro located across the park can feel that they are in the nature as walking closer the housing district. The programs of the complex are grocery, retails and communication space.

The park is sustained by the grey water collecting system and provides free green space for the community.

Ventilation & Grey Water

5 feet extra spaces among each slab creates plenum space for ventilation. All ventilation spaces started from infront of the building which face to river side to the pened lobby so whole building is connected by one big air circulation. Also, this plenum spaces also create suken living spaces, bedrooms and bathrooms in each living unit.

Rain water is collected and filtered into each tank located below the community center. The inverted gable roof of the building makes the path of the rain. The vertical transparent path shows the filetering process of the grey water from inside to people to educate them.

SWACO VISITING CENTER Autum 2010 3rd year undergraduate studio, tutored by b professor r e so Laurie La r Gunzleman G n em m The terrain of the Swaco Landfill is under constant flux because of changes in the collected trash. The main idea of the building starts by reversing the expectation that people usually want to conceal trash through use of landfills. This visiting center recovers the tainted land by embeding into the site, and creating a spectacle of the changing landscape. The center reclaims the lost landscape and the shifting mounds are changed from trash to spectacular display.


22 Swaco visiting center

The main exhibition space is a ramp and it makes dynamic view of the landfill.

Form & Circulation The circulation of the visiting center is motivated by the Art of Jim Denevan. By arraying and increasing the simple forms such as circles, they give one big dynamic image. The main purpose of the visiting center is to stimulate people to participate in reducing waste. I thought that the artwork can be translated to the circulation with the idea that a little change in thinking, each visitor can make a big change.

The purpose of the visitor center is to create an educational experience that will change peoples relationship to garbage. The center attracts people l to t move through th h it with ith its it spiral circulation greating dynamic views. Through carefuly curated views the buildings openings frame moments of the landscape extending the exhibition beyond the gallery and makes the visitor rethink the trash we create.


The ramp circulation starts from the main entrance. By taking the ramps, visitors can feel the floor shifting beneath them like the changing “ground� outside.

NEGOTIATING GESTURE Autum 2010 Studio A, tutored by professor Laurie Gunzleman The main idea started from the two different intertwined grid systems on the site. The problem is that there is already north market on the site, so the Whole Foods market and the local market would be located very close and sharing their front space. As the features of the programs of the each building, they should decide on sharing their program or to seperate. For solving this situation, parking space and grocery are clearly seperated and restaurants and bars are connected to the second floor of the north market. The connection space becomes the gesture of the negotiation.

Types and Intensities of Uses

ECO/SPLIT is a design for a sustainable lab and surrounding campus on the island of St. Croix. Research of the environment is meant to help people gain a better understanding of nature. By distinguishing the different eco-systems within the site users become more aware of the variations featured in the landscape. By using architecture to separate the various ecologies the program becomes the edge and users are able to experience multiple environments simultaneously throughout the site.
