The proposal contains a discussion of the systems of the SHA 707 Building and some possible alternative systems.  The possible redesign solutions to improve occupancy thermal comfort, energy consumption, and a faster paced schedule than what is currently being renovated.  The primary redesign will include active chilled beams to replace the current induction units.  This alteration will lead to a resize in chiller and boiler systems.

Note: While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work-in-progress for this thesis project.  Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Stephanie Kunkel. Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design.

When implemented, any mechanical system redesign will consequently alter other building systems.  After feedback from design engineers, construction management and lighting/electrical breaths will be analyzed during the Spring 2011 Semester.

Construction Management

This construction management breadth will investigate the potential savings in construction costs and installation schedule.  With the design engineer’s current prediction of a lengthy 9 phases being implemented in the 707 Building systems renovation, a more rapid installation schedule will be examined.  Specific research will be gathered for the cost, schedule, and commissioning for any change to the mechanical system.

Designing a system with chilled beams leads to the ability to combine several services in a single integrated unit.  Aside from known HVAC services, a full range of building services such as fully addressable lighting solutions, fire alarms, and sprinkler heads can be incorporated into the beam.  A decrease in costs and on-site installation time is nearly guaranteed by incorporating fire protection and/or lighting features into the beam.


A lighting/electrical breadth will examine the benefits of multiservice integration within the chilled beams in the office space.  A reduction in the cooling load is also plausible with this renovation.  With the resizing of the chiller and boiler, an alteration in electric load will most likely occur.  Design loads for the building’s current electrical distribution system will be compared to the redesigned system.  An electrical study will be performed comparing the current electric load output to the renovated one.

The revised proposal contains a discussion of the systems of the SHA 707 Building and some possible alternative systems.  An additional study of the current two-pipe heating and cooling system replaced by four-pipe system was added to the depth report.  A more extensive breadth summary was also added to this revised proposal.
