Sample Monitoring Report
An example of the recurring report an Ongoing Controls Support engagement provides.
Example data for a fictional facility, shown to demonstrate the deliverable format. Not a real building or client.
This sample monthly report records system activity, completed work, and the watch list for an Ongoing Controls Support engagement. The month below continues the story of the example building partway into an engagement that began with the findings recorded in the sample controls assessment: alarm counts are falling as alarm definitions are reviewed, and the overrides found during the assessment are being released one repair at a time.
Month at a glance
For scale, the front end was logging over three thousand alarms a month when the engagement began.
| Measure | This month | Last month |
|---|---|---|
| Alarms logged | 1,480 | 2,190 |
| Alarms that required action | 21 | 34 |
| Overrides active at month end | 4 | 6 |
| Comfort calls | 5 | 8 |
| Weekly backup exports verified | 4 of 4 | 4 of 4 |
| Points on trend | 380 | 310 |
Top alarm sources
Counts are for the month; status is as of the report date.
| Alarm source | Count | Status |
|---|---|---|
| VAV-3-11 airflow out of range | 214 | Failing damper actuator; the box is overridden to a fixed position until the replacement arrives |
| AHU-1 supply air temperature deviation | 163 | Cooling valve loop was hunting; retuned late in the month and holding since |
| AHU-2 filter differential pressure | 96 | Filters changed; the alarm threshold, unchanged since 2009, was reset to match the installed filters |
| VAV-2-05 zone temperature out of range | 88 | Stuck reheat valve repaired mid-month; the alarm has stayed clear since |
| Floor 3 trunk device offline | 61 | Down sharply since the trunk configuration cleanup; one controller still drops off and is on the watch list |
Overrides in place
Four overrides are active, down from six last month and from the nine found during the assessment. Every override in this report includes a reason and a planned release. Missing reasons or release plans need follow-up.
- AHU-2 outside air damper, held at minimum position. The low-limit bypass found during the assessment was removed early in the engagement, and the freeze-stat trips traced to an economizer damper that would not fully close. The hold comes off when the linkage repair is complete.
- VAV-3-11 damper, held at a fixed position while the failed actuator awaits its replacement. Releases on installation.
- VAV-1-06 reheat valve, commanded closed after it was found leaking through. The zone is holding temperature on airflow alone; releases when the valve is rebuilt.
- AHU-3 supply air temperature setpoint, held 2 degrees below the reset schedule at the floor 3 tenant's request during their fit-out. Releases when construction ends.
Actions taken and watch list
- Repaired the stuck reheat valve at VAV-2-05; the zone alarm cleared mid-month and stayed clear.
- Retuned the AHU-1 cooling valve loop after the supply air deviation alarms; no deviations since the retune.
- Retired or rethresholded another block of nuisance alarm definitions, most of them left over from the 2009 database. This is the work behind the falling alarm count.
- Added 70 points to trend collection, prioritized on the plant and AHU-2, bringing coverage to 380 of the roughly 2,400 points.
- Verified all four weekly backup exports of the front-end database and controller programs, and test-opened one export.
- Watch: compressor starts on the air-cooled chiller, original 1996 equipment, are still trending up year over year. The replacement budgeting recommendation from the assessment stands.
- Watch: one zone controller on the floor 3 trunk keeps dropping offline after the configuration cleanup. A secondary-market spare has been sourced; if the drops continue, replacement is next.
- Watch: boiler run hours are rebalancing since lead-lag rotation went back to automatic, but boiler 1 still leads by a wide margin.
Use consistent measures to follow changes from month to month. In this example, the alarm count has fallen from over three thousand a month at the start of the engagement to 1,480. Continue reviewing alarm definitions and tracking which alarms require action.
