Mechanical Depth
In this proposal, design alternatives are proposed for Coolidge High School’s mechanical system. Currently, Coolidge High School utilizes a variable refrigerant heat recovery system as well as three rooftop units and one air handling unit to heat and cool the various spaces. A dedicated outdoor air system is used for tempered ventilation. After assessing the existing scope in Technical Reports 1, 2, and 3, various alternatives were explored for the mechanical system redesign. However, only two were chosen:
-
Adjust the air distribution in the atriums with the use of displacement diffusers
-
Replace the VRF heat recovery system with a geothermal heat pump system
The primary focus of the spring semester will be researching and conducting an analysis on a combination of both alternatives. By conducting these changes, they will ideally increase energy savings, improve thermal comfort, improve air distribution in the atriums, and properly adjust the heating and cooling loads.
Breadths
PLUMBING
When observing the project documentation, Coolidge High School contains a large amount of restroom in order to support its staff. Overall, the high school utilizes conventional plumbing fixtures. With the number of students and faculty that occupy the school, the water consumption will be greatly reduced if low flush fixtures are implemented. This breadth will analyze the water consumption of Coolidge High School and will compare the use of conventional fixtures with low- flush fixtures.
CONSTRUCTION
With the implementation of low-flush fixtures, the cost of the installation and labor will be analyzed to determine whether or not the low-flush fixtures are beneficial in comparison to the school’s water consumption. A schedule will be created to determine if the installation of the fixtures produces savings in both time and cost.
MAE Integration
The mechanical depth is divided into two analyses: displacement diffusers and geothermal heat pump system. The analysis on displacement diffusers will utilize material covered in AE 559: Computational Fluid Dynamics in Building Design. In addition, the material in AE 558: Central Heating Systems will be used for the design of the geothermal heat pump system.
