THESIS WORK

FINAL PRESENTATION

I just finished final presentations. Here are some of the boards from the wall.

ENTER ECOTECT

ALEX HOGREFE — Mon, 01 Mar 2010 05:30:43 +0000

A large percentage of the south façade requires protection from solar heat gains in the summer. Using concepts from earlier Grasshopper definitions, a new definition was developed to:

Generate different densities, thus changing visibility based on interior needs
Provide adequate shading
Continue the concept of shifting lines in the articulation of the façade

The definition solves these problems by expanding and contracting the density based on placement of attractor points. As the louver spacing increases, they also become deeper, maintaining proper shading. The louver system can be generated on any wall imported into the definition allowing for quick testing and analysis.

Above, early study of different louver compisitions applied to an arena wall

I brought the louver system into Ecotect to test out the performance of the wall in reduction of solar radiation. Two louver systems were looked at; the multi-depth system providing wider louvers where openings are bigger, and a single depth system. Though more tests will be done, Ecotect revealed that the multi-depth system provides more consistant shading over the entire surface, ever where the louver spacing is larger.

While the changes are subtle, the definition is producing positive results. I hope to get more dramatic results with further testing.

Finally, some images of the BGSU arena digital model at its current stage.

ARENA SEATING PARAMETRIC MODEL

ALEX HOGREFE — Tue, 09 Feb 2010 16:02:11 +0000

To aid in the design of the transforming arena seating, I created a parametric model that would allow me to test out the mechanics of the structure as well as the density, spacing, slope, site lines, and other factors.

Just to recap, the Lecture hall seating faces outwards through a large glass curtain wall to an outdoor amphitheater allowing the system to double as seating for outdoor performances. I will be exploring how the curtain wall can open in the future. Movable walls separate individual lecture halls creating sound isolating rooms. When the seating transforms to the arena side, it provides ideal site lines to the court

THESIS PROGRESS: JANUARY

ALEX HOGREFE — Mon, 25 Jan 2010 04:31:07 +0000

The form development has shifted to focus on pedestrian traffic. Early diagrams showed that circulation through the site was not very efficient due to parking lots and the library plinth. I designed a Grasshopper definition that would generate new pedestrian paths. I also wanted the definition to insert a small degree of chaos. This was due to the fact that people do not walk exactly the same paths and have to shift directions when passing others. Finally, an attempt was made to push main intersections of pedestrian paths closer to the new arena which would create opportunities of gathering places and building entry points. The result was an interesting assembly of line work that I then overlayed on the site plan and began cutting away ground and building form.

Early on in the project, I wanted to push ideas of transformation within the arena. I have begun working out details of the arena seating transforming into lecture hall seating, and multiple other uses. Issues I am running into is acousticly separating lecture hall rooms from each other while avoiding site line disturbance for the arena seating.

MIDWAY POINT

ALEX HOGREFE — Mon, 21 Dec 2009 18:55:01 +0000

For the midway point of the thesis design, maturity of building program, site location, and site development were required. As of right now, the arena will be engaged with the library mass, with the outdoor amphitheater facing north toward the cemetery. A classroom bridge will extend from the main arena mass to Olscamp Hall (classroom and lecture halls) also acting as a sound buffer for the theater and the rest of campus. Program adjacencies and square footages are also established. The next steps will be working with Ecotect and Grasshopper to begin sound analysis and lighting analysis of the present massing. I am interested in how the building can possibly transform to accommodate multiple sound and lighting scenarios with the outdoor theater, arena, and underground parking structure. Finally, maintaining pedestrian paths through the site is still important to the building development and form, so I will be exploring strategies to maintain these walkways.

Below, a process board showing showing the evolution of the present arena massing engaged with the campus library tower. In step 5, a physical model was introduced which proved to be helpful in transitioning into a more rational building form

A few of the iterations looked at in step 3 of site forces

Below is the current state of the arena massing. The form is based on earlier studies of site forces and also the transformations of surround building axis and forms. The end result is the appearence of the landscape peeling up into the arena spaces, sloping for the outdoor amphitheater, and bridges connecting surround campus buildings.

FORCE STUDIES 2

ALEX HOGREFE — Mon, 16 Nov 2009 14:16:01 +0000

From the initial force study, it was determined that the arena location needed a connection to Wooster St. (a high-traffic, prominent street on the south end of campus leading directly to downtown). The Rhino model was therefore extended across the Library plinth to a proposed green space adjacent to the street. This would provide a visual as well as physical connect between Wooster St. and the new arena site.

FORCE STUDIES

ALEX HOGREFE — Fri, 13 Nov 2009 05:28:26 +0000

Looking at Site 2 on the BGSU campus, an exploration of possible massing and site planning was achieved through an application of forces.

First, forces such as views, building adjacencies, and privacy were used to create vertical space. Next, forces were used to create transparency by rotating strips up for underground parking and program.

High pedestrian traffic from nearby dormitories and car traffic were expressed through horizontal forces.

Finally, vertical and horizontal forces were combined in a final model

SITE ANALYSIS

ALEX HOGREFE — Sat, 07 Nov 2009 20:21:42 +0000

The project I have decided to pursue for my thesis is the development of an arena located on the Bowling Green State University campus. The campus plans to build a new arena by 2012. They have chosen a site which is location 1 on the site analysis drawings. I will be questioning this site location, and explore other opportunities closer to the core of campus.

Arenas have remained widely unchanged for many years, except for the amenities they contain. I have researched several case studies that are exceptions, one of which being the Saitama Super Arena in Japan. This arena utilizes kinetic architecture to provide a transforming space for small uses such as basketball games and small concerts, but can expand seating capacity 10x for large concerts and American football games.

There is an opportunity for a university arena to take on these transformative capabilities to utilize all of the available square footage. I will be exploring possibilities of lecture halls doubling as seating for arena events, and indoor structure transforming into outdoor amphitheater space.
