Shopping mall
energy monitoring
Energy by area and by equipment across the mall: atrium, car park, food court, chillers, lifts and lighting. Metered at the distribution panels and compared in one place.
THE PROBLEM
Common areas are the biggest tenant nobody meters
A mall runs long hours with large shared loads: central cooling, escalators and lifts, car park ventilation and lighting, the food court extract. These costs flow into the service charge, and tenants increasingly ask how they were calculated.
The engineering team has a different question. Which area is costing more this summer than last, and why? Is the car park lighting following its schedule? Did the chiller sequence change after the last service? Answering them takes data by area and by equipment.
Malls also change constantly. Units merge, a cinema arrives, an anchor store leaves. Any metering scheme has to cope with boundaries that move.
HOW WE SET IT UP
Meter the panels, compare the areas
Metering at the distribution panels
We meter the panels that serve each zone and each major equipment group. That gives area and equipment breakdowns from a manageable number of points, without metering every circuit.
Agree the allocation method first
Shared loads can be allocated by area, by metered share or by a hybrid. We help the facility team document the method before data collection starts, so the reports support the service charge from day one.
Equipment data through Modbus
Chillers, AHUs and many lift and escalator controllers already expose energy and status over Modbus. Our gateway reads them alongside the panel meters, so equipment and area data share one timeline.
Schedules and alerts
Rules in RIOD Live compare consumption against trading hours and alert the duty engineer by WhatsApp, SMS or call when lighting or ventilation runs outside schedule.

FAQ
Questions buyers ask us
How is common area electricity allocated in a shopping mall?
Usually by leasable area, by a metered share of each zone, or by a mix of the two written into the lease. Metering at the distribution panels gives the data for any of these methods, as long as the method is agreed and documented before reports are issued.
Which mall loads use the most electricity?
Cooling is usually the largest, followed by lighting, vertical transport and car park ventilation. The order varies with climate and design, which is why metering those groups separately is the first step in any reduction plan.
Can we monitor the mall without metering every shop?
Yes. Metering at panel and equipment level covers the shared loads and the major plant with far fewer points. Tenant sub-metering can be added in stages as leases renew.
Can the mall BMS receive this data?
Yes. Data in RIOD Live can be passed to a BMS or energy management system through an API, and the gateway can also read data out of the BMS side where it exposes Modbus.
