The person on site is a store manager, not an engineer.
HVAC dominates the load, the landlord frequently owns the meter, and the maintenance record is whatever the visiting technician chose to write down.

The sector problem
Store formats repeat, so consumption should too. When one store runs materially hotter than its twin in the same city, that is a fault — but it only reads as a fault if the two are ever compared.
Where to start
Attest
Start hereStore-versus-store benchmarking on identical formats, plus an independent read on the FM partner's own reports.
Sustain
Where contractedBackup power maintenance where the retailer holds it directly rather than through the mall.
Meter
SelectiveSubmetering earns its place where landlord billing has to be challenged with an independent measurement.
Evidence
Working alongside a facility management partner rather than in place of one — the verification layer sits above whoever holds the service contract.
