Data limitation
- Site-level monthly data cannot localise the cause to a specific asset.
- Additional sub-meter or BMS data is required to identify the responsible asset.
- Sample stream only. No live BMS or IoT connectivity.

03 Solution
Recommended solution
What should be done?
Primary action
Restore the weekday unoccupied setback on AHU-07 from 20:00 GST.
Schedule exception left in place after weekend event.
01 Review
Review Zone 4 cooling load against the expected envelope.
02 Confirm occupancy
Confirm occupancy and schedule context for the deviation window.
03 Adjust
Reduce Zone 4 cooling operation between 15:00–17:30.
04 Confirm
Confirm the schedule change on the cooling plant.
05 Measure
Compare post-action demand against the 371 kW expected load.
06 Verify
Record evidence-backed before/after comparison in the Impact Ledger.

How this was calculatedShow workingHide working
Sample record. Quantities come from the sample meter window; values are derived as shown.
1. Water avoided per year
(15,680 − 3,280) L/night × 365 nights
= 4,526,000 L
2. Volume in cubic metres
4,526,000 L ÷ 1,000
= 4,526.0 m³
3. Financial value
4,526.0 m³ × 8.00 AED/m³
= AED 36,208
4. Carbon avoided
Not calculated — no confirmed water emission factor
= —
Assumptions used
- Water rate: 8 AED / m³Sample assumptionIllustrative sample rate. Not a published tariff. Replace with the site's billed rate.
- Water supply emission factor: noneNot availableNo confirmed published factor located. Carbon is not calculated for water records until a confirmed factor is supplied.
