In the high-humidity, high-density environment of Kuala Lumpur, a Ventilation System Audit is a specialized mechanical and volumetric assessment of your building's "respiratory" health. As of 2026, many commercial and industrial facilities in KL are operating at 30% lower efficiency than their design intent due to mechanical wear, sensor drift, or outdated control logic.
At EKG, we perform these audits to bridge the gap between "it's running" and "it's optimized," focusing on your AHUs, fresh air intakes, and motor performance.
We evaluate your ventilation infrastructure across three intersecting performance zones:
Regulatory Compliance (DOSH/JKKP): We verify that your facility meets the 2026 Malaysian Industrial Code of Practice (ICOP) for Indoor Air Quality, specifically the target of 10 L/s per person for fresh air.
Mechanical Integrity: We inspect fan impellers, bearings, and belts. We look for the vibration and friction that steal energy before the air even leaves the AHU.
Volumetric Accuracy: We measure the "Actual vs. Design" airflow. We often find "Ghost Air"—volume that is paid for at the motor but lost to duct leaks or internal bypass.
Our engineers use precision diagnostic tools to map your system’s true performance:
Duct Traverse & Velocity Mapping: We use calibrated Vane Anemometers and Pitot tubes to measure the exact volume (CMH) at the fan discharge. This identifies if "Belt Slip" or "Motor Drag" is causing losses.
Building Pressure Differential Test: To keep out KL’s 90% outdoor humidity, a building needs Positive Pressure (typically +10 to +25 Pa). We use digital manometers to ensure your building isn't "sucking" in hot, wet air.
VFD & Electrical Load Auditing: We analyze your Variable Frequency Drive (VFD) settings. If they are pinned at 50Hz (Full Speed) 24/7, your "smart" system is effectively a constant-speed energy waste.
"Dead Zone" Smoke Tracing: We use non-toxic smoke tracers to visually confirm airflow paths, identifying stagnant areas where heat or moisture pools due to poor diffuser placement.
A ventilation audit is the "Financial Case" for system optimization. Most energy waste in KL is caused by fans fighting unnecessary resistance (dirty coils, clogged filters, or seized dampers).
Friction Restoration: By identifying and removing these bottlenecks, we lower the "Total Static Pressure" the fan must fight.
The Logic: Because of the Cube Law, a 20% reduction in fan speed results in a nearly 50% reduction in power consumption. An audit provides the mechanical data to safely lower your VFD frequencies.
| Component | Healthy Grade | At-Risk Sign (Failure) |
| Fresh Air Intake | > 10 L/s per person | Stale Air / High CO2 (>1000 ppm) |
| Cooling Coil Resistance | 100 to 150 Pa | > 250 Pa (Deep Clean Needed) |
| Fan Vibration | < 2.5 mm/s | > 4.5 mm/s (Bearing Failure) |
| Building Pressure | Positive (+10 Pa) | Negative (Sweating Vents/Mold) |
| Energy Efficiency | Demand-Based Control | Constant Speed (50Hz) Waste |
Holistic Repair Path: We don't just give you a report. We are experts in Mechanical Fan Overhauls, offering chemical degreasing, bearing replacement, and laser alignment to fix the issues we find.
BOMBA & Safety Ready: We provide witness testing for smoke-spill and staircase pressurization systems, ensuring they hit required safety targets for Fire Certificate (FC) renewals.
VFD ROI Projection: We calculate exactly how much money you are "exhausting" into the street, providing a clear Ringgit-based ROI for any recommended repairs.
2026 Compliance: Our reports are designed to meet the latest Malaysian Energy Commission (ST) and DOSH efficiency mandates.
