Green Division High-rise

GREEN DIVSION HIGHRISE/グリーンディビジョンハイライズ

BY KANISHA FOWELL

GREEN DIVSION HIGHRISE IS ABOUT THE INCLUSION OF GREEN SPACE AND VERTICAL URBAN FARMING WITHIN A HIGHRISE. THE PROJECT MAKES USE OF A CANTILIVERED STRUCTURE TO ALLOW FOR OPEN GREEN SPACES/ PARKS.THE FOLLOWING PAGES WILL DISPLAY THE PROCESS, WITH ANALYSIS OF THE MASSING, AND THE OUTCOME.

DYNAMO - REFINERY

F.A.R. & MASSING

The project began in Dynamo, as seen in the graph above, and Refinery. A generic mass was formed, with number of floors, height of building, F.A.R and B.C.R all taken into consideration.

Though the site is somewhat triangular, I decided to work with a rectangualar building coverage on the site. In Insight 360 and Green building studio, it was found that the building would produce 2 241 kWh/m . By optimizing the engery, I got the building down to 2 84.2 kWh/m . While this is lower than the Ashrae standard, it does not meet the AIA 2030 standard, which would be creating a Carbon Neutral structure. Later on this will be adressed.

ENVIRONMENTAL ANALYSIS

SUN AND WIND ANALYSIS The site is located just outside of the Shinjuku ward, and is technically in the Shibuya ward, in Tokyo Japan. As the site name suggests, the closest train station is Shinjku Station.

Below is the wind rose for winter and summer, obtained from green building studio. With the wind rose information, I conducted the wind analysis in Autodesk Flow. The wind anaylsis includes how wind acts in elevation, and how the wind acts towards what would be the green spaces of the highrise. As it can be seen, the wind creates eddies in elevation. And is strongest towards the edges of the green areas. Note, the strongest possible winds for the respected times of year were used to conduct this analysis.

To the right are sun studies. The shadow studies show that during summer the building would mostly cas shadows on its own site. In conctrast during the winter, the shadows are longer and get cast onto the neighboring buildings.

The solar analysis showed that the building can be subjected 2 to as much as 851 kWh/m . Later I examine one of the faces, that could potentially produce energy for the highrise. Both this analysis and the shadow study showed that the green space are shaded, due to the cantilever.

FLOOR PLANS

EXTERIOR TO INTERIOR

On the previous pages the diagram of program displays how the building is broken up into several programs, commercial, office, hotel and residential, by the two floor open for green space. The two cores are located to the begining of the cantiliever.

drop off is in the basement level. Service trucks may go all the way around to get to the service entrances. The spaces was previously used as a field for sports, so I decided to leave some space for a child park.

Though the surronding buildings are not highrises, there is one highrise nearby, which this new structure competes with. This can clearly be seen in section.

The plan to the left displays the residential area. An important component of this building is the vertical urban farming. In the highrise, urban farming can be found on various levels. In some cases they take up the entire floor.

The location of the building on it’s site is also important as it uses the diagonal paralell road. The structure pauses the Shinjuku Gyoen park, then continues the park idea on the other side. The entrance area is an open park, with paths that guide the user into the building.

There is a road around the site for cars, as parking and hotel

In the case of the residential area, they are at the center of the apartment circulation. Every resident has access to this space, and can contribute to, as well as obtain food from these indoor farms. It becomes a communal farming space.

STRUCTURE

As stated before, I was able to get the building down to 84.2 2 kWh/m . This is lower than the Ashrae standard but does not meet the AIA 2030 standard, which would be creating a Carbon Neutral structure. To obtain carbin neutrality I decided to use solar panels. I examined the building face that would recieve the 2 most solar raditaion. This face can produce 144 kWh/m . This 2 would bring the building energy consumption to -59.8 kWh/m .

2 Or in other words the building would be producing 59.8 kWh/m .

Thus the building meets the AIA 2030 standard.

On the adjacent page the strcuture of the highrise can be seen.

Trusses were used to support the cantilevers. As Japan has high sesmic activity, the highrise needed bracing. External bracing was used. The bracing of the building aligns with the shear walls and is centeralized on the fcacde.

The following pages show renderings of the interior apartment space, the exterior green spaces and the ground activities.
