In the high-performance building landscape of 2026 Kuala Lumpur, Duct Leakage Testing (DLT) has transitioned from a commissioning formality to a mandatory regulatory requirement. Under the Energy Efficiency & Conservation Act (EECA) 2024, which came into full effect on January 1, 2025, commercial and industrial buildings must optimize their Building Energy Intensity (BEI) to maintain a minimum 2-star rating. A leaking duct system is a primary source of illegal energy waste, often causing fans to run 33% harder just to compensate for air lost in the ceiling plenum.
As part of our specialized Duct Leakage Testing category, EKG M&E provides the certified forensics and pressure testing required to ensure your facility is airtight, compliant, and cost-efficient.
Under the latest MS1525:2024 and EECA standards, duct integrity is a pillar of energy management:
The 3% Leakage Limit: For medium to high-pressure systems in KL's commercial towers, we target SMACNA Class A or DW/143 Class B standards, ensuring total leakage stays below 3% of design airflow.
Maximum Demand (MD) Control: By sealing leaks, we reduce the load on your AHU fans. This allows your VSD to drop the motor frequency ($Hz$), directly lowering your monthly TNB Maximum Demand charges.
Condensation & Mold Prevention: In Malaysia's 90% humidity, air leaks cause "Ceiling Sweating." Our testing prevents the moisture buildup that leads to mold, ensuring you stay below the DOSH ICOP IAQ limit of 500 cfu/m³.
We utilize high-precision automated equipment (such as the Kanomax DALT 6905) to provide certified Duct Air Leakage Testing (DALT):
Pressurized Sectional Testing: We isolate sections of the ductwork using inflatable plugs and measure the exact $L/s$ leakage rate at the system's "Operating Static Pressure."
Ultrasonic Leak Pinpointing: For inaccessible risers in high-rise buildings, we use ultrasonic "Pingers" to locate microscopic gaps in mastic seals or gaskets without the need for ceiling demolition.
Thermal Infrared Audits: Using FLIR Thermal Cameras, we identify "Cold Plumes" in the ceiling void, providing visual evidence of where your cooling Ringgits are escaping.
Smoke Injection Verification: We use non-toxic artificial smoke to visually confirm seal integrity during final commissioning or for BOMBA smoke-spill system audits.
A certified performance test is the foundation of your building's Energy Intensity Label:
Optimizing the VSD Setpoint: Most buildings in the Klang Valley over-pressurize their ducts. We find the lowest possible setpoint that satisfies all zones, capturing maximum Cube Law energy savings.
The Logic: Because of the Cube Law, a 20% reduction in fan speed (made possible by a sealed system) results in a nearly 50% reduction in power consumption.
EECA 2024 Documentation: We provide the "Certified Leakage Report" required for your Registered Energy Manager (REM) or Auditor (REA) to submit to the Energy Commission (ST).

Mechanical Restoration Path: We don't just "read a meter"; we are experts in Mechanical Fan Overhauls. We ensure your AHU is physically capable of the performance targets we measure.
VFD-Energy ROI Projection: We use digital power loggers to provide a baseline report, proving exactly how much your energy bill will drop once leaks are sealed.
Rapid Response: Based in Kuala Lumpur, we specialize in "After-Hours" testing for occupied office towers (KLCC, TRX, PJ) to ensure zero noise disruption for your tenants.
34 Years of Depth: As a Malaysian HVAC leader, we bridge the gap between legacy M&E infrastructure and 2026 smart-building requirements.
