Commissioning (TAB) Duct Leakage Reports

Commissioning (TAB) Duct Leakage Reports by EKG M&E Sdn Bhd

In the 2026 Malaysian regulatory framework, Commissioning TAB (Testing, Adjusting, and Balancing) and Duct Leakage Reports are no longer independent tasks. Under the Energy Efficiency and Conservation Act (EECA) 2024 and the latest DOSH ICOP IAQ 2026, a TAB report is legally incomplete without verified duct airtightness data. For buildings in Kuala Lumpur and Selangor, these reports serve as the primary "Birth Certificate" for a facility's HVAC performance.

At EKG M&E Sdn Bhd, we apply 34 years of mechanical depth to provide integrated TAB and Leakage reports that ensure your building achieves its 5-Star Energy Intensity Label from day one.

1. The Strategic Link: Leakage vs. Balancing

You cannot balance a system that is leaking. If air escapes before reaching the terminal device, the balancing data becomes mathematically invalid.

• Pre-TAB Leakage Verification: Per NEBB and AABC standards, duct leakage testing (DW143) must be completed before final air balancing. If leakage exceeds 5%, the fan energy required to "punch" air to the furthest diffuser increases exponentially, violating 2026 energy efficiency targets.

• Proportional Tuning: Our TAB reports correlate the "Design Flow" ($CFM/LPS$) with the "Measured Leakage" at the AHU. This allows us to calibrate your Variable Frequency Drives (VFDs) to the lowest possible frequency that still satisfies the most distant zone.

• Bio-Security Proof: A certified TAB report proves the building is under positive pressure, while the leakage report proves the "Injection Path" is sealed. Together, they satisfy the DOSH 2026 requirement to prevent the infiltration of mold and humid Malaysian air.

2. Anatomy of an EKG Commissioning Report

Our 2026 digital reports are designed for immediate submission to the Energy Commission (Suruhanjaya Tenaga) and DOSH:

• Section A: Duct Leakage Certification (DW143/DW144)

  • Certified leakage rates in $l/s/m^2$.

  • Pressure category validation (Class A, B, or C).

  • Smoke test verification photos for critical fire-rated risers.

• Section B: Testing & Adjusting Data

  • Amperage and Voltage logs for all fan motors.

  • Static Pressure profiles ($Pa$) across coils and filters.

  • Fan Speed (RPM) settings vs. VFD output ($Hz$).

• Section C: Final Balancing Schedule

  • Proportional air distribution for every diffuser and grille.

  • "Before & After" flow readings to prove system stabilization.

  • Tolerance check (confirming all zones are within +/- 10% of design).

3. Compliance & EECA 2024 Synergy

At EKG M&E Sdn Bhd, our commissioning reports provide the "Audit Trail" required for your building's star rating:

4. Why Professional TAB Matters for Your Asset

• Avoiding "Ghost Cooling": Reports prove that cooled air isn't being dumped into ceiling voids (via leaks) or over-delivered to unoccupied zones (via poor balancing).

• BOMBA Fire Safety: For smoke spill systems, the TAB/Leakage report proves that the extraction path maintains the negative pressure required to keep escape routes clear.

• Asset Longevity: Balanced systems experience less mechanical vibration and motor heat, extending the lifespan of your chillers and AHUs.

Why Choose EKG M&E Sdn Bhd?

• 34 Years of Engineering Depth: Based in KL, we understand the mechanical physics of the plant. We ensure that our TAB adjustments never compromise your Smart Actuators or internal insulation.

• Turnkey Reporting: We provide a single, comprehensive digital file that satisfies your Registered Energy Manager (REM) and your Insurance/Fire Safety requirements.

• 3D BIM Coordination: For new projects, we identify "Balancing Ports" and "Test Zones" in 3D to ensure commissioning is fast, accurate, and non-disruptive.

Is your facility's commissioning data audit-ready or just a paperwork formality? Contact EKG M&E Sdn Bhd today for integrated TAB and Duct Leakage reports and secure the efficiency and compliance of your building.
