In 2026, a "Building Fresh Air Supply" is no longer just a passive vent in the wall. Following the enforcement of the Industry Code of Practice (ICOP) on IAQ 2026 by JKKP/DOSH and the updated MS 1525:2019 standards, fresh air systems in Kuala Lumpur must be active, filtered, and precisely controlled.
At EKG M&E Sdn Bhd, we design fresh air supply systems that serve as the "primary defense" for your indoor environment, ensuring that every cubic meter of air entering your building is cleaned of city pollutants and stripped of tropical humidity.
The 2026 Malaysian standards have become more stringent to prevent "Sick Building Syndrome" and improve cognitive performance. We design to the following benchmarks:
General Office Space: A minimum of 10 l/s per person of outdoor fresh air.
High-Density Areas (Meeting Rooms): Scaled rates based on ASHRAE 62.1-2022, often requiring dynamic adjustment via $CO_2$ sensors.
Building Pressure: We maintain a Positive Pressure of 5–12 Pa relative to the outdoors. This prevents "Infiltration"—the uninvited entry of hot, humid air through gaps in the building envelope that causes wall mold.
Because Kuala Lumpur's outdoor air can contain high levels of $PM_{2.5}$ during haze season, a single filter is insufficient. Our supply stacks include:
Pre-Filter (G4): Captures large dust and insects to protect the main system.
Secondary Filter (MERV 13/14): The 2026 standard for stripping out fine combustion particles and haze.
Optional HEPA (H13): For critical zones (server rooms, clinics), ensuring 99.97% air purity.
Activated Carbon: Neutralizes city odors and vehicle exhaust (VOCs) from nearby traffic.
The most significant energy waste in a building is cooling fresh air when the building is empty. We solve this using Variable Frequency Drives (VFDs):
Demand Controlled Ventilation (DCV): Our $CO_2$ sensors talk to the VFD on the Fresh Air Fan. If the office is half-full, the VFD slows the fan to the exact required flow.
The Cube Law Efficiency: Because fan power follows the cube of the speed, a 20% reduction in fan speed leads to a 49% reduction in power consumption.
Soft-Start Technology: VFDs prevent "Inrush Current" spikes that damage motors, extending the lifespan of your ventilation equipment by years.
Fresh air fans often sit on rooftops exposed to the elements, making them prone to bearing wear and imbalance. Our maintenance includes:
Vibration Spectrum Analysis: We use FFT (Fast Fourier Transform) analysis to listen to your fans. We can detect a failing bearing or a misaligned belt months before it causes a system shutdown.
BMS Integration: Your fresh air status is visible 24/7 on your dashboard, with alerts sent directly to our team if airflow drops below 2026 compliance levels.
34-Year Legacy: Since 1992, we have been the "Air Architects" for KL's commercial towers and data centers.
ICOP 2026 Readiness: We are experts in the new DOSH regulations, ensuring your building passes every IAQ audit.
Turnkey Engineering: We handle the Ductwork, VFD Control Panels, Filtration Upgrades, and Commissioning Reports.
