Thesis Proposal

Proposal Executive Summary (.pdf)
The goals for this thesis are to improve the energy efficiency of the SLCC and the acoustics of the sensitive audiology labs. To do this, I am proposing a wholistic solution that focuses on meeting these goals. One audiology lab in particular will be studied and the findings will be extrapolated throughout the buiding. This lab is on the third floor of the three story wing and subject to internal equipment loads and solar heat gain through the roof. My solution is to apply (active) chilled beams supplied by constant dedicated outdoor air, and an unoccupied, extensive green roof.
The chilled beam application was selected for its potential energy and space savings because energy is transported with water instead of air. As a result, the amount of air flow in the mechanical system is reduced thus decreasing ductwork, filter sizes, equipment sizes, fan power, etc. VAV boxes can be eliminated thus quieting the system. Significant energy and cost savings are expected but they will be offset by a potential increase in first cost. An acoustic study will be performed to verify the chilled beam application in these NC-20 and NC-25 spaces.
The green roof is expected to improve thermal insulation in the third floor spaces. Additionally, stormwater management and acoustic insulation from ambient street/equipment noise are predicted benefits of this application.
