Background
The Middle East region is advancing building energy efficiency regulations. Dubai mandates Al Sa’fat green building system requiring energy sub-metering; Saudi SEEC monitors building energy compliance under Vision 2030. Buildings without BMS need cost-effective solutions to meet these requirements while achieving tenant billing transparency and electrical safety.
Pain & Value
Your Pain Points
Without circuit-level sub-metering and tenant-independent billing, cannot verify energy saving effectiveness nor allocate electricity costs accurately among tenants.
Integrating energy meters from multiple brands into existing building infrastructure requires complex vendor coordination and raises long-term maintenance risks.
Lack of real-time visibility into critical circuit risks (over-temperature, leakage, overload) leads to delayed response and potential electrical fire hazards.

Solution
Acrel BMS-Free Building Energy Monitoring Solution
Sub-Metering for Multiple Functional Circuits
Installed in floor distribution boxes, ADW210 measures up to 4 three-phase circuits (lighting, HVAC, power sockets, elevators) with one unit. It provides voltage, current, power, harmonics (2-31st) and unbalance data via RS485 Modbus. Ideal for buildings that need to separate energy consumption by end-use category to meet Al Sa’fat sub-metering requirements.
Independent Billing for Multiple Tenants
Installed in floor distribution boxes, ADF400L supports up to 36 single-phase or 12 three-phase tenant circuits with modular combination. It features built-in Ethernet (Modbus-TCP) for direct LAN connection and supports prepaid functions (remote on/off, time control, load limit). Ideal for office towers, apartments and hotels requiring separate energy accounting per tenant.
Safety Monitoring for Critical Circuits
Installed at the end of distribution boxes, AESP110 monitors voltage, current, power, temperature, leakage and overload for a single critical circuit. It uses Modbu-RTU / TCP, 4G, WIFI to send real-time alarms to the gateway. Ideal for protecting sensitive equipment such as data center racks, medical devices, or kitchen appliances against overheating, leakage and overload.
ADW210, ADF400L and AESP110 work together as a complete energy management solution for buildings without a BMS.
ADW210 handles sub-metering by separating energy consumption of lighting, HVAC, sockets and elevators – essential for compliance reporting.
ADF400L manages tenant billing with independent circuits and prepaid control – eliminating cost allocation disputes.
AESP110 protects critical circuits with real-time monitoring of temperature, leakage and overload – reducing electrical fire risks.
Together, they provide visibility, control and safety from the floor distribution box to the end load.
