Thesis Proposal


Lighting Depth
The lighting depth involves the redesign of the lighting system of four spaces: Main Lobby, Patron's Lounge, Main auditorium, and Event Plaza. The new design aims to create an engaging and welcoming environment that resonates with the community, complements the architecture, and celebrates the arts. Spaces should be functional, in which light levels meet specified recommendations in the IES Handbook. Power density requirements, as presented in Standard 90.1, should also be met.

Electrical Depth
The electrical depth includes the redesign of the branch circuit systems of the four spaces to be re-illuminated. To accomodate the new lighting system and controls, lighting and equipment loads will be altered; therefore, feeders and panelboards will be resized for branch circuit modifications. A protective device coordination study will be conducted, addressing a single path through the distribution system, which extends from the CPS Energy utility to a new lighting panel, LP-4AA. A short circuit calculation study will be produced. Additionally, the depth will include the study of building-integrated photovoltaics and a comparison of a centralized transformer to the existing distributed transformers.

Mechanical/Sustainability Breadth
The mechanical breadth will include utilizing biogas as a renewable energy source for onsite use. Research will be conducted to understand how such greenhouse gases can be transformed into a power source and used as energy for electricty and heat generation. Further studies will focus on system implementation and interaction with the HVAC and power distribution systems.

Construction Management Breadth
Contributing to a possible implementation of a Building-Integrated Photovoltaic system, an in-depth cost and schedule study will be performed. Assembly estimates and actual supplier/vendor quotes will be presented, as well as comparative case studies of how this
system can impact construction time and cost. These can provide insight on inital cost offsets and the amount of building materials
and labor necessary.
