Great Eastern Mall & Office: Sub-Metering and Centralised Energy Reporting

About the property

Great Eastern Mall & Office is a mixed-use building in Kuala Lumpur: retail floors with many tenants sitting beneath occupied office space. Two very different load profiles share one structure. Mall floors swing with trading hours, foot traffic, and tenant fit-outs. Office floors follow a steadier weekday rhythm. Common services such as chillers, lifts, car park ventilation, and lighting run across both, billed back to whoever the lease says is responsible.

That mix is exactly what makes a single utility meter useless for managing cost. Consumption is spread across dozens of areas and systems, and one headline figure on the TNB invoice cannot tell you which part of the building is driving it.

The challenge: energy you can't see until the bill arrives

Energy data was scattered and after-the-fact. Readings lived in separate places, there was no consolidated view across the mall and office, and pulling a report meant manually collecting numbers from multiple sources. By the time anyone had a picture of the month, the month was already over.

Maximum demand made this worse. Maximum demand is a major component of a commercial electricity bill, charged on the highest power draw recorded in the period, yet it was effectively a blind spot until the invoice landed. A single coincident peak, chillers ramping while the car park fans and a tenant's plant all kick in at once, can set the demand charge for the whole month. Without visibility as it happens, the operations team had no way to know a peak was forming, let alone act on it.

For a multi-tenant property there is a second problem underneath the first: fair, defensible cost allocation. If you cannot measure who consumes what, every conversation about recoverable charges starts from estimates.

The solution: one platform, every point sub-metered

CobiNeural sub-meters across the property and consolidates every point into one platform, deployed as an overlay on the building's existing metering rather than a rip-and-replace. The data hierarchy follows the building itself: locations (mall, office, common services) down to equipment and individual sensors, so consumption can be read at whatever level the question demands.

The modules that carry this deployment map directly to the building's gaps:

- Insights -> Energy gives the operations team consumption, power factor, EUI, and the Max Demand KPI at location and equipment level. Demand is no longer a number that appears once a month; peaks are visible as they build.
- Reporting turns consolidated data into automated, scheduled energy reports. The work that used to mean manually assembling figures now runs on its own, and the same reporting backbone supports EECA-aligned anomaly and energy-saving-measure reporting when the property needs it.
- Dashboards put the whole property on one live view, so mall, office, and shared services are read side by side instead of in separate spreadsheets.
- Billing & Tariffs provides the tenant cost allocation a multi-tenant building needs, backing recoverable charges with measured sub-metered consumption rather than estimates.

With demand visible in real time, the same platform opens the door to acting on it. Through Actions and automation, peak-shaving and chiller-plant control sit on top of the monitoring once the team is ready to move from seeing peaks to flattening them.

The result

Great Eastern Mall & Office now runs from a single source of truth for the whole property. Reporting that used to take days takes minutes, and maximum demand has gone from a line item discovered after the fact to a metric the operations team can watch as it moves. Sub-metering means every floor, system, and tenant area is measurable, which is the foundation for both cost control and fair allocation.

More than a dashboard, it is the groundwork for an ISO 50001-aligned way of running the building: measure first, report reliably, then optimise.

Considering the same for your building?

If your property's energy lives in separate meters and last month's invoices, the first step is making it visible in one place. See how other facilities did it, or talk to us about consolidating your building's energy data and bringing maximum demand under control.
