DOSH ICOP IAQ 2026 AHU Audits: Fresh Air Intake Rate Verification

In Kuala Lumpur’s enclosed office towers, fresh air isn't a luxury anymore. Under the DOSH ICOP IAQ 2026, it’s the law.

When an Air Handling Unit (AHU) recycles the same stale air all day, CO2 levels spike. Tenants get headaches, productivity crashes, and you risk severe statutory penalties for "Sick Building Syndrome."

But you can't just throw the fresh air dampers wide open. Pulling in too much 33°C tropical air forces your chillers to overwork, destroying your energy budget.

You need perfect balance. As specialized mechanical installation contractors, EKG (Malaysia) SDN BHD provides forensic Fresh Air Intake Rate Verification. We replace guesswork with hard aerodynamic data.

Here is how our verification protocol works.

1. Volumetric Airflow Traversing (The CMH Test)

We don’t trust digital building software blindly.

A computer might say the fresh air damper is "20% open," but if the mechanical linkage is broken, the blade hasn't moved. We insert calibrated anemometers directly into the intake ducts to measure the true physical air volume in Cubic Meters per Hour (CMH).

2. Live CO2 & IAQ Profiling

We test the air where it matters: inside the office space.

Using calibrated environmental sensors, we track live CO2 parts-per-million (ppm) alongside peak occupancy hours. This proves whether your current fresh air intake is actually keeping your tenants safe and legally compliant.

3. Mechanical Damper Calibration

If your fresh air rates are off, we fix the hardware on the spot.

We clean, lubricate, and adjust the motorized linkages on your outdoor, return, and spill air dampers. We ensure they actuate smoothly, preventing them from jamming open (wasting energy) or jamming shut (suffocating tenants).

4. BMS Sensor Zeroing

Once the mechanics are perfect, we sync the brain.

We recalibrate your digital differential pressure transducers and CO2 sensors back to absolute zero. This ensures your central Building Management System (BMS) makes automated, energy-saving decisions based on true, verified physical data.


The EKG Execution Standard

We don’t just verify your air; we secure your entire plant room.

Neutralizing The Sponge Effect (DOSH IAQ 2026):

Drawing in humid fresh air often causes internal condensation. If your AHU relies on old fiberglass insulation, it acts like a sponge, breeding toxic mold. We strip this out and install Fiber-Free Closed-Cell Insulation—a permanent, hydrophobic skin that keeps your air pristine.

Securing Specific Fan Power (EECA 2024):

By calibrating exact fresh air volumes, we prevent your fan motors from overworking against unnecessary static pressure. This keeps your system efficiency safely below the strict MS 1525 thresholds, lowering your TNB utility bills.

The Hardwired BOMBA Override:

Fresh air dampers are a major fire hazard. If a fire breaks out, the AHU cannot keep feeding fresh oxygen to the flames. We manually verify your hardwired fire interlocks, ensuring the AHU instantly bypasses all software to execute immediate smoke-spill or emergency shutdown sequences.

Stop Guessing. Start Verifying.

Don't wait for a tenant complaint or an IAQ compliance failure to figure out your dampers are stuck.
