Commercial Sub-Metering & Electricity Tracking — Bill Tenants, Find Waste, Save Money

Per-Floor. Per-Tenant. Per-Circuit.

Commercial sub-metering is the practice of installing dedicated meters on each tenant feeder, floor, or major load — so landlords can bill tenants accurately, identify hidden waste, and meet regulatory disclosure requirements. Tech OVN's Titan smart meter does this with WiFi or Ethernet to a cloud dashboard, no gateway hardware required.

Why Sub-Meter?

Most commercial buildings have one utility meter for the whole building and a single bill that gets divided up using rough proportional formulas — square footage, headcount, or worse, equal split. Tenants who consume less subsidise tenants who consume more. Landlords have no visibility into where energy is being wasted. Sustainability teams can't report Scope 2 emissions per tenant.

Sub-metering replaces the formula with measurement. Every tenant pays for exactly what they use. Every floor has a baseline. Every major load can be tracked over time. And studies consistently show buildings with sub-metering reduce energy costs by 10–30% within the first year — just because the data exists and someone is looking at it.

What Titan Sub-Metering Delivers

Five outcomes from accurate, granular metering across every tenant and circuit.

Per-Tenant Cost Allocation

Defensible meter-backed bills. Tenants see their own consumption, their own cost, their own carbon footprint. Disputes drop sharply.

Cost Recovery for Landlords

Stop subsidising heavy users. Bill each tenant for their actual share — including HVAC, lighting, EV charging, and tenant equipment.

Energy Waste Detection

After-hours loads, phantom power, mis-set HVAC schedules — sub-metering surfaces the patterns that bulk billing hides.

Tenant Dashboards

Through the Energy Intelligence Platform, tenants get role-restricted dashboards showing only their data. Property managers get the portfolio view.

Compliance Reporting

ESG disclosure, CSRD, BRSR, GRESB, LEED, and BREEAM all benefit from sub-meter data. CO₂ on every meter, calculated per source.

Where It Fits

Five common building types where Titan sub-metering pays back quickly.

Office Buildings & Co-Working

Allocate energy cost per tenant, per floor, or per workspace. Show ESG-conscious tenants their consumption and emissions.

Shopping Centres & Retail Parks

Per-unit billing for retail tenants. Common-area tracking. HVAC and lighting cost transparency.

Industrial Estates

Sub-metering on each unit's incoming feeder. Heavy machinery, compressors, lighting — all tracked separately.

Mixed-Use Developments

Residential plus commercial in one building, with different tariffs and different reporting requirements per occupant type.

Hotels & Hospitality

Track HVAC, F&B, laundry, lighting, and back-of-house systems separately. Tie consumption to occupancy.

How It's Different from a Gateway System

Traditional sub-metering systems use Modbus RTU meters connected to a gateway, which connects to a server, which runs licensed software, which renders the dashboard. Every layer adds cost, complexity, and a maintenance contract.

Titan connects directly to the cloud over WiFi or Ethernet. No gateway. No on-premise server. No annual software licence per meter. The same hardware that meters the circuit also commissions itself via the Tech OVN App, buffers data during outages, and rolls up to the cloud dashboard automatically.

For a 20-meter deployment, that's roughly the cost of the meters alone — versus meters + gateways + server + licences for a traditional setup.

Frequently Asked Questions

Seven common questions about commercial sub-metering, accuracy, tenant billing, and ESG reporting.

Most jurisdictions require Class 1.0 or better for sub-billing. Titan is Class 0.5S — twice as accurate, and the same class utilities use for revenue billing. That accuracy makes disputes very hard to win.
No. Titan connects directly to the building WiFi or Ethernet network and streams to the cloud. There is no on-premise gateway, server, or hub.
There's no upper limit. The Energy Intelligence Platform supports portfolio-level views with drill-down to any individual meter — designed to scale from a single building to a thousand.
Yes. Role-based access control limits each tenant to their own meters, consumption, cost, and carbon footprint. They never see other tenants' data.
Studies consistently show 10–30% energy cost reduction within the first year of installing sub-metering and acting on the data. The biggest source is identifying after-hours loads, mis-set HVAC schedules, and phantom power that bulk billing hides.
Yes. Titan exports data via Modbus RTU/TCP and MQTT. Your BMS sees the meters as standard Modbus devices.
The platform calculates Scope 2 CO₂ emissions automatically using configurable grid emission factors per source. Per-tenant carbon footprints feed directly into ESG reports and CSRD submissions.
