In the humid, high-traffic environment of Kuala Lumpur, an Air Quality Audit is the ultimate health check for your building. While a mechanical fan moves the air, the quality of that air determines occupant productivity, health, and the lifespan of your interior assets. In 2026, air quality is no longer just about "smell"—it is about precise concentrations of particulates, gases, and microbial threats.
As part of a Ventilation Systems Audit, EKG provides a data-driven map of your indoor environment, linking air pollutants directly to your fan and filtration performance.
We monitor the key indicators of Indoor Air Quality (IAQ) that impact human health and mechanical efficiency:
Particulate Matter (PM2.5 and PM10): Fine dust and haze particles that bypass standard filters. High levels indicate leaking ductwork or "Filter Bypass" at the AHU.
Carbon Dioxide (CO2): The primary indicator of "Stagnant Air." High CO2 levels (above 1000 ppm) lead to drowsiness, headaches, and poor decision-making in office environments.
Volatile Organic Compounds (VOCs): Chemical "off-gassing" from carpets, paints, and cleaning agents. Without proper Air Changes (ACH), these toxins reach harmful concentrations.
Relative Humidity (RH): In KL, humidity above 65 percent leads to mold growth in ducts and "sweating" on supply grilles, which eventually destroys ceiling boards.
We don't just leave a sensor in a room; we track the air's journey through your mechanical system:
Multi-Point Data Logging: We deploy sensors across "High-Load" areas (conference rooms, pantries) and "Low-Load" areas to identify stagnant zones.
Filter Efficiency Testing: We measure the particle count before and after your AHU filters. This proves whether your filters are actually stopping PM2.5 or if they are "leaking" air around the edges.
Ductwork Hygiene Inspection: We use robotic cameras to check for mold or accumulated dust inside the supply ducts, which can act as a continuous source of pollution.
Fresh Air Correlation: We sync air quality data with your Fresh Air Intake Volume. If CO2 spikes at 2 PM, we know your dampers aren't opening wide enough during peak occupancy.
Air Quality Audits are the foundation for Demand Control Ventilation (DCV). If your air quality is "Perfect," you are likely over-ventilating and wasting money.
Sensor-Based Speed Control: By linking your Variable Frequency Drive (VFD) to CO2 sensors, the fan only speeds up when air quality drops.
The Logic: Because of the Cube Law, a 20 percent reduction in fan speed results in a nearly 50 percent reduction in power consumption. An Air Quality Audit gives you the "Data Confidence" to slow down your fans during low-occupancy hours without compromising health.
| Parameter | Target Range (Healthy) | Mechanical Solution |
| CO2 Level | < 1,000 ppm | Increase Fresh Air Intake / VFD Speed |
| PM2.5 | < 35 ug/m3 | Upgrade to MERV-13+ Filtration |
| Humidity | 40 to 60 percent | Check Coil Temp & Condensate Drainage |
| Air Velocity | 0.15 to 0.50 m/s | Dampers & Diffuser Balancing |
| VOCs | < 3 ppm | Increase Air Changes (ACH) |
Certified IAQ Assessors: Our audits follow the Department of Occupational Safety and Health (DOSH) Industrial Code of Practice (ICOP) for indoor air quality.
Mechanical Correction: Unlike "Lab-only" firms, we are mechanical experts. If we find bad air, we can immediately perform a Mechanical Fan Overhaul or Duct Cleaning to fix it.
Mold & Microbiological Testing: For buildings with persistent odors or "Sick Building Syndrome," we perform surface swabbing and air sampling to identify specific fungal species.
VFD Optimization Reports: We provide a roadmap for your BMS, showing exactly how to program your fan speeds to balance energy savings with peak air quality.
