Testing & Commissioning (T&C): Specific Fan Power (SFP) Benchmark Testing

In the 2026 Malaysian regulatory landscape, Specific Fan Power (SFP) Benchmark Testing has become the primary metric for mechanical compliance. Under the Energy Efficiency and Conservation Act (EECA) 2024, SFP is a "Pass/Fail" statutory requirement for all commercial and industrial buildings. It is no longer enough to have a functional AHU; the system must prove it moves air with maximum electrical efficiency to satisfy the Suruhanjaya Tenaga (ST).

At EKG (Malaysia) SDN BHD, our mechanical specialists lead SFP testing to ensure your VFD-driven AHU meets the mandatory benchmarks required for your building's Energy Intensity (BEI) certification.

1. The Statutory Benchmark: MS 1525:2024

The MS 1525:2024 code (the technical standard for EECA 2024) defines the maximum allowable SFP for air distribution systems.

The Penalty of Failure: Systems exceeding these limits are flagged by Registered Energy Auditors (REA). Failure to remediate can lead to statutory fines and the denial of the annual Fire Certificate (FC) renewal if the system is deemed structurally inefficient.

2. The EKG SFP Verification Formula

We utilize simultaneous data logging to calculate the "Actual" SFP of your system in real-time:

• $P_{fan}$: The total electrical power input to the fan (including VFD losses), measured in kW.

• $Q_{air}$: The total volumetric airflow delivered by the fan, measured in m³/s.

Verification Protocol: We measure $P_{fan}$ directly from the motor terminals using power quality analyzers, while $Q_{air}$ is verified via a Duct Airflow Traverse to ensure the reading reflects the air actually reaching the building, not just the fan's theoretical curve.

3. Engineering for "SFP Optimization"

If an AHU fails its benchmark test, it is usually due to high system resistance. At EKG (Malaysia) SDN BHD, we identify the root cause within the AHU Ducting Service:

1. ESP Audit (External Static Pressure): We measure the pressure drop across coils, filters, and silencers. If the External Static Pressure is higher than design, the fan works harder, spiking the SFP.

2. Filter Integrity Check: Clogged or low-quality filters are the #1 cause of SFP failure. We verify that MERV 13+ filters are clean and sized correctly to minimize resistance.

3. VFD Logic Calibration: We verify the VFD Integrated Static Pressure Transducer. By implementing Static Pressure Reset logic, we allow the SFP to drop significantly during partial load conditions (e.g., lunch hours), which is a key requirement for the 2026 EnMS reporting.

4. Life-Safety & "Fire Mode" Integration

SFP benchmarks must be maintained without compromising the life-safety requirements of BOMBA (JBPM) 2026.

• Automatic Fire Signal AHU Shut-off: We verify that the energy-efficient VFD controls yield instantly to the fire alarm signal.

• Smoke-Spill Fan SFP: Even emergency fans (like smoke extraction fans) are now subject to SFP monitoring to ensure they don't overload the Emergency Power Supply during a fire event.

• BOMBA Audit: JBPM officers review SFP data during the annual Fire Certificate (FC) audit to ensure the mechanical system hasn't been "downgraded" or neglected in a way that risks motor failure.

5. Why Partner with EKG (Malaysia) SDN BHD?

• Technical Integrity: We are installation and T&C specialists, not fabricators. Our SFP testing is an objective, empirical assessment of your system’s real-world health.

• GITA Prerequisite: Our SFP benchmark reports are the primary evidence used for GITA (Green Investment Tax Allowance) claims, certifying your equipment as "High Efficiency."

• Audit-Ready Reporting: We provide a structured SFP Performance Certificate that is ready for submission to your Registered Energy Manager (REM).
