APS-George Sanchez Collaborative Community School
Project Description:
Named after the civil rights activist George Sanchez, the collaborative community school services over 1,300 students.
It is the first school in APS to combine elementary and middle school students. The school served as a prototype for future K-8 schools.
Scope of Work:
TMCx provided LEED Fundamental and Enhanced commissioning. Design activities included design and submittal review and comment, Cx plan and document development. Construction activities included site installation verification, water system flush verification, witness of equipment startup and TAB, and functional testing. Post-occupancy activities include 10 month and 3 year warranty follow up site inspections.

Challenges and Successes
- During the installation phase it was found that sections of the return air ductwork was missing turning vanes. As a result, with the turning vanes in place, it allows for the air to flow easily through the square elbows, reducing pressure loss and fan horsepower.
- During functional testing, it was found that the air handling units did not have discharge air temperature reset for heating. As the heating load rises, the hot water valves at the terminal units open 100% but are unable to heat the spaces. There is discharge air temp reset for cooling modes in the sequence but not for heating. This is a reason there has been “too cold” in spaces complaint calls. As a result, the controls contractor programmed the air handling unit to reset the discharge air temp as needed for heating per the new sequence of operations. With this program installed it allows the AHU to reset the discharge air temperature when there is a heating need in the spaces.
