Facility Project Assignment:
HVAC Troubleshooting and Maintenance – System Comparison
Learning Objective: Understand and evaluate system conditions and capacity
to determine whether or not O&M can satisfy occupant requirements.
1. The assignment is an exercise to compare original design and operating
conditions to actual conditions that exist in the facility.
2. Compare the original settings to the current operating conditions. What
items can be controlled or adjusted, and what items need system alterations?
How has the facility demands changed, and what alteration, improvements or
changes have been made to the HVAC.
