### Asset Description:
AHU: Air Handling Unit: A device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.

### Conditions:
- AHU Running
- SubType NOT RAS or OAU or VAV
- Day NOT Monday
- 55 °F < OAT < 80 °F
- Setpoint Temperature = Setpoint Temperature 1 Hour Ago
- Setpoint Temperature = Setpoint Temperature 2 Hours Ago
- Setpoint Temperature = Daily Average Setpoint Temperature 1 Day in the Past
- Setpoint Temperature = Daily Average Setpoint Temperature 2 Days in the Past
- None Reporting

### How long the conditions were met:
NONE

Review the listed conditions and identify which option LEAST likely to account for them.
A. Static pressure sensors need calibration, repair or replacement
B. Opportunity for additional savings. Reset temperature to outside conditions
C. BMS maybe over ridden to a constant value.


# Answer

Answer: A. Static pressure sensors need calibration, repair or replacement

Guidance Rationale: 

The Air Handling Unit (AHU) is running, with none of the
reported values showing fluctuations, and the outside air temperature (OAT) is
in a moderate range between 55 °F and 80 °F. Additionally, the setpoint
temperature has remained unchanged over multiple time windows: 1 hour ago, 2
hours ago, and over two previous days' daily averages. This pattern strongly
suggests that the system is locked to a fixed setpoint, potentially due to
manual override or a missed opportunity for dynamic control based on ambient
conditions (e.g., weather-based temperature reset). There is no indication of
instability or fluctuation in system performance that would typically arise from
faulty or miscalibrated static pressure sensors. 

In contrast, option B suggests an opportunity for additional savings by resetting the 
temperature to outside conditions, which aligns with the observed stable setpoint and moderate OAT.
Option C, indicating that the Building Management System (BMS) may be overridden
to a constant value, also fits well with the unchanging setpoint temperature.
Therefore, the least likely explanation for the observed conditions is: "Static
pressure sensors need calibration, repair or replacement."
