The following proposal details the work to be completed in the Spring of 2010. It presents a description of the redesign of several systems present in Sherrerd Hall, a campus building at Princeton University. Included are explanations of two depth, two breadth topics, a topic related to the Master of Architectural Engineering degree, and a topic related to the Honors College thesis requirements.
depth analysis: lighting
The lighting depth presents new design concepts in five building spaces: the exterior façade at the main entrance, the central building core with lobby/atrium/stair, an open work space, a graduate bullpen, and a lecture hall. The new design aims to create an aesthetically dynamic and comfortable atmosphere that is tailored to the needs of the occupants. Sherrerd Hall is metaphorically a bridge housing two departments that promote collaboration across conventionally distinct disciplines. Thus, the main goal for the lighting should be to enhance the sense of transparency and movement throughout the building to promote collaboration, interaction, and cross-pollination. The architect has employed a number of unique materials and finishes to the building to enhance this sense of transparency, and light should be applied in such a way that there is effective interaction between surfaces and light. The design must enhance the architect’s philosophy that “a building is an assemblage of use, material, and light.”
The space should also be functional, with light levels that meet those specified by the IESNA. The designs must also meet all power density requirements presented in ASHRAE 90.1.
depth analysis: electrical
The electrical depth includes a redesign of the branch circuit distribution for the five spaces to be re‐illuminated. A protective device coordination study and short circuit analysis will also be conducted. The redesign of the HVAC system based on curtainwall modifications will lead to changes in design loads. The selection of distribution equipment and protective devices for this redesigned portion of the system will be necessary. An investigation into the economic and performance impacts of changing the entire electrical feeder system from copper to aluminum will also be completed.
breadth analysis: mechanical
The mechanical breadth will be developed in conjunction with the extensive daylighting study in spaces adjacent to the curtainwall system and the large atrium skylight. The mechanical breadth will cover the effect of varying panel types within the curtainwall system and reconfiguring the large skylight over the atrium. The adjusted thermal gains and losses will be estimated and used to inform redesigns to the HVAC system.
breadth analysis: structural
The structural breadth will also be developed in conjunction with the daylighting study related to the large atrium skylight. The study will include a redesign of the roof framing system to accommodate for the reconfiguration and sizing of the skylight spanning the building core atrium.
m.a.e. focus: daylighting
Daylighting integration and control is one of the driving factors in the lighting design for Sherrerd Hall. The building is entirely enclosed by a curtainwall system on all four façades. Fritted transparent panels and translucent panels allow daylight penetration, while opaque panels are applied where daylight penetration is undesirable. In several of the spaces, a reconfiguration of these panels could allow for a far more comfortable visual experience for the occupants. A study of the current daylight penetration will inform panel reconfiguration. The reconfiguration of panels within the curtainwall system also needs to consider its implications for thermal gains or losses, and this study will be integrated with a mechanical breadth topic. Ultimately, this portion of the daylight study should culminate with a set of recommendations for panel configurations and material changes (if any). The reconfiguration of a large skylight spanning the building core atrium will also be studied with this topic. The report will also include daylight responsive control system design.
honors focus: daylighting in perimeter office spaces
There are many perimeter office spaces in the building that are not within the scope of the other five spaces considered in the lighting design portion of the thesis. These spaces have access to daylight and should be integrating daylight to provide comfort to the occupants and to reduce building energy loads. As part of an additional study to meet the requirements of the Schreyer Honors College thesis, a daylight study will be conducted in several of these offices (which are typically repeated all along each façade). This report will consider curtainwall panel reconfiguration and a daylight responsive control system design.
