Final Proposal

Analysis 1 | Mechanical System

The proposed mechanical system for the replacement high school is a geothermal system with over 437 wells all at a depth of 400 feet.  A system of this magnitude comes with a significant upfront cost for installation.  To curb this cost I will look into implementing a hybrid geothermal system so that the owner will still receive the benefits of using geothermal wells, but will have additional funds to allocate elsewhere.

Analysis 2 | Solar Energy Conversion System (SECS)

The current design for the replacement high school pays little attention to the possibility for implementing solar devices.  Due to the location of the school and lack of surrounding structures the use of photovoltaic panels could prove to be beneficial to the owner.  I will look into potential arrays for this building and determine the feasibility.

Analysis 3 | Alternate Delivery Method

Due to a two month delay on the Notice to Proceed, a lot of additional pressure was put on the CM agency.  I will investigate an alternate design build approach to construct this school to see if and how some of these pressures could be alleviated.  To do this I will compare Hess Constructions current contractual agreements with one of their typical design build contracts.

Analysis 4 | Facade Prefabrication

A large portion of the exterior façade is made up of hand laid ground face CMU.  In an effort to decrease the schedule I will investigate the implementation of a precast façade.  I will have to look into the logistical issues associated with doing this.

Mechanical Breadth | Relates to Analysis #1

The current mechanical system is comprised of 437 geothermal wells that connect to nine 30 ton water-to-water heat pump modules.  To decrease the installation costs associated with this system the number of wells and modules will be reduced.  To compensate for the loss in heating and cooling capacity a cooling tower will be implemented on the roof of the mechanical room and a boiler will be added.  Energy modeling will be performed on both the current system and the newly presented one in order to create a life cycle analysis.  This analysis will depict the maintenance life, installation costs, differences in energy requirements, and other critical items to adequately compare the two systems.

Structural Breadth | Relates to Analysis #1

Because the redesign of the mechanical system will require the installation of a cooling tower on the roof of the mechanical room, a structural analysis will have to be performed.  Load calculations will be computed to illustrate the impact of the additional weight on the current roof structure.  Once the loads have been determined a redesign of the structural system for that area or the building will be performed.  Any costs associated with the change in structure will be incorporated into the cost for changing the mechanical system.

Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Christopher Ankeny. 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.
