In the 2026 Malaysian regulatory landscape, the AHU Airflow Test is the mechanical benchmark for compliance with the Energy Efficiency and Conservation Act (EECA) 2024. This test verifies that the AHU is delivering the design volume of air ($m^3/h$ or $L/s$) required to satisfy the thermal and latent loads of the building while remaining within the statutory Specific Fan Power (SFP) limit of 1.6 kW/m³/s.
At EKG (Malaysia) SDN BHD, our airflow testing protocols are Statutory-Compliant and Data-Driven, providing the empirical evidence needed for your Registered Energy Manager (REM) and BOMBA submissions.
Under current 2026 enforcement, the Airflow Test is no longer optional; it is a prerequisite for building occupancy and energy intensity (BEI) certification.
SFP Verification: We measure the fan motor’s kW draw simultaneously with the airflow to calculate the SFP. Exceeding 1.6 kW/m³/s can lead to statutory penalties or the failure of a GITA (Green Investment Tax Allowance) application.
Volumetric Accuracy: Per MS 1525:2024, the total measured airflow must be within ±10% of the design specifications.
Indoor Air Quality (IAQ): The test ensures the AHU delivers the minimum "Fresh Air" volume required to keep CO2 levels below 1,000 ppm, satisfying DOSH 2026 health mandates.
We utilize the Duct Traverse Method, which is the most accurate engineering approach for measuring total system volume.
We drill small test holes in the main supply duct (typically in a straight run to ensure laminar flow). We then use a Pitot Tube or Hot-Wire Anemometer to take a grid of readings across the duct's cross-section.
The average velocity ($V_{avg}$) is multiplied by the cross-sectional area ($A$) of the duct to determine the Total Airflow ($Q$):
We test the airflow at various VFD (Variable Frequency Drive) increments (e.g., 30Hz, 40Hz, 50Hz). This creates a "System Curve" that proves the VFD Integrated Static Pressure Transducer is correctly modulating the fan to save energy during partial loads.
The accuracy of an airflow test depends entirely on the quality of the Ducting Installation.
Straight Run Requirement: For a valid traverse, the measurement point should be located at least 7.5 duct diameters downstream and 3 diameters upstream of any elbows or transitions.
Laminar vs. Turbulent Flow: Poorly installed ducts with "kinks" or sharp bends create turbulent air that makes accurate testing impossible. EKG utilizes BIM-Coordinated Integration to ensure testable, high-efficiency air paths.
Static Pressure Verification: We simultaneously measure the External Static Pressure (ESP) to ensure the fan is not struggling against an "over-resistant" system.
The Airflow Test includes a mandatory high-velocity check to satisfy BOMBA (JBPM) 2026 safety standards.
Smoke Spill Verification: In a fire event, the system may switch to "Smoke Spill" mode. We verify that the AHU can move the statutory volume of air required to exhaust smoke from the fire zone.
Damper Integration: We verify that the Motorized Fire Dampers (MFDs) do not create excessive resistance that would compromise the airflow during an emergency.
BOMBA Audit: JBPM officers often witness the 100% capacity airflow test during the annual Fire Certificate (FC) audit.
Technical Integrity: We are installation and T&C specialists, not fabricators. Our tests are objective and performed with NATA-traceable, calibrated instruments.
Audit-Ready Reports: We provide a comprehensive Airflow Verification Report (including velocity grids and SFP calculations) required by your Registered Energy Auditor (REA).
Zero-Footprint Retrofit: If your current airflow is insufficient, we can perform an ESP Audit to identify "bottlenecks" and optimize your system for 2026 compliance.
