Thesis Proposal

Lighting Depth
The four spaces to be redesigned are the south façade and grounds, café, atrium and reference reading room. These areas designate the most highly populated path of pedestrians through the library and will show how the lighting concept can be applied to many different room types.
Schematic lighting design concepts developed during the fall semester will be refined and finalized in order to move into the design development stage in the spring semester. Each space will be fully designed and documented in a full set of plans including fixture schedules meeting ASHRAE 90.1 2010 requirements.

Electrical Depth
The electrical depth will in part be a response to the changes made during the redesign of the lighting from the four spaces chosen for study. This will consist of calculating loads and resizing panels to adapt to these changes. The main focus of the depth after all the fixture changes are complete is to reevaluate the loads on the building by switching to a dual bus system. This system will allow the building to run on both AC and DC power. The new DC bus system will supply power to LED luminaires, AV/IT devices, data and telecom centers, sensors and controls as well as security and safety equipment. The existing photovoltaic system will be the main power source to the DC powered equipment with electrical power converted from AC to DC as a backup. A cost analysis will be performed based on the new equipment that will be added and the transformers that will no longer be needed.
Breadth Proposal #1 – Architectural
The architectural breadth for the redesign of the Princeton Theological Seminary Library will be focused on the atrium. A daylighting study will be performed using Daysim to analyze the performance of the existing sidelighting, clerestories and skylights. The goal will be to receive quality daylight that will allow for dimming in the atrium and surrounding areas. The proposed solution is to remove the bridges located on the western side of the atrium that connect the addition to the existing Luce Building and relocate the hallways to the center of the building. Rerouting this circulation will open up the western facade to bring more daylight into the atrium and create a more convenient circulation path for the users of the building. This solution will be tested in Daysim in order to confirm the benefit of these changes.
Breadth Proposal #2 – Structural
The structural breadth will be determined by the results of the architectural breadth. The relocation of the bridges will make an impact on the existing structure and require additonal members to be added to each floor. An analysis will be performed on the members that support the existing bridges for possible reduction of member size. The area of relocation for the hallway will also be analyzed to resize existing members based on new loading conditions and determine sizes for new members. Typical loading conditions will be researched in order to determine the member sizes in the hallway and surrounding areas that are affected. Before these changes are made, a study of the existing structure of the building will be performed in order to understand how to approach the redesign.
