Shopping Mall Energy Intelligence — Tenant Sub-Metering | EC.DATA

Shopping Mall Energy Management — Tenant Sub-Metering & CAM Recovery

EC.DATA enables shopping centres to sub-meter every tenant, automate CAM (common area maintenance) cost recovery, and optimize central HVAC and chiller plant operations — eliminating energy cost disputes and reducing operating expenses.

Mall Energy Challenges

Tenant energy allocation is manual, inaccurate, and disputed
CAM cost recovery based on floor-area pro-rata rather than actual consumption
Central chiller and HVAC plant running at full capacity regardless of tenant occupancy
After-hours consumption by tenants not contractually authorized
Anchor tenant demand peaks driving utility bill for the whole property
No benchmark data for energy intensity by retail category or floor

EC.DATA Mall Solutions

EC.Billing: automated tenant sub-metering with invoice generation and consumption dispute resolution
CAM recovery with metered allocation: electricity, chilled water, and BTU measured at each tenancy
EC.BMS: central chiller and HVAC optimization based on tenant occupancy schedules
EC.Chillers: chilled-water plant COP monitoring and approach temperature diagnostics
After-hours tenant consumption alerts and automated shut-off scheduling (EC.Alerts)
Portfolio benchmarking by retail category, floor, and wing

Shopping malls: metering what tenants actually use

The gap between floor-area pro-rata CAM recovery and actual metered consumption typically runs 15–30% in favour of high-energy tenants like food courts and anchor department stores — meaning other tenants cross-subsidize them every month. EC.DATA's mall solution places BTU meters on every chilled-water connection and Modbus CT meters on every tenant electrical panel, then runs the tariff allocation calculation automatically at month-end to generate tenant invoices. Disputes drop to near zero because every invoice references a timestamped sub-meter reading.
