Energy Management

Sub-metering at plant, floor and tenant level — electrical kWh, thermal BTU and water — Modbus-networked and data-ready for any EMIS, BMS or compliance reporting platform.

15–30%

Typical energy saving identified in first year with sub-metering

Class 0.5S

Electrical meter accuracy — bankable-grade for LEED credit

MID Class 2

BTU meter certification — legal-for-billing thermal metering

Modbus RTU

Standard protocol — works with any EMIS or BMS platform

Building a sub-metering hierarchy

Effective energy management requires measurement at multiple levels. A single utility main meter tells you the total bill; it tells you nothing about which system is wasting energy or which tenant is over-consuming. Sub-meters at each level answer the questions that drive action:

Level	What you learn	Meter type
Plant level	Chiller, boiler and AHU kWh breakdown	AG-EMT-300 (3-phase, Class 0.5S)
Floor level	Which floors over-consume vs benchmark	AG-EMT-300 or AG-SCM-400
Tenant level	Individual tenant consumption for billing	AG-SCM-400 (electrical), AG-UHM-100 (thermal)
Circuit level	Lighting vs HVAC vs plug load split	AG-SCM-400 per circuit

All meters communicate via Modbus RTU on RS-485. Up to 32 meters daisy-chain on a single cable pair — dramatically reducing wiring cost versus individual analogue cables.

LEED v4.1 EAc2 guidance

LEED requires separate sub-metering of HVAC, lighting, plug loads, domestic hot water and process loads. Our AG-SCM-400 DIN-rail meters provide the circuit-level data needed for LEED documentation — contact us for a metering schedule review.
