In 2026, Office Ventilation Injection—the process of actively forcing filtered outdoor air into a building—is the primary mechanical requirement for legal occupancy in Malaysia. Under the DOSH ICOP IAQ 2026 and the EECA 2024, buildings are moving away from passive "fresh air dampers" toward active, sensor-driven Dedicated Outdoor Air Systems (DOAS).
At EKG M&E, we apply 34 years of mechanical engineering to bridge the gap between "Air Volume" and "Air Quality," ensuring your office meets the mandatory 10 l/s per person threshold while maintaining a 5-star Energy Intensity Label.
The DOSH 2026 update has solidified the requirement for fresh air. To pass a federal health audit, your injection system must be calibrated to these physical parameters:
Mandatory Rate: At least 10 liters per second (l/s) per person.
The 1,000 ppm Barrier: Carbon Dioxide is the legal "Proxy" for ventilation. If your injection system cannot keep CO2 below 1,000 ppm, your building is non-compliant.
Standard IAQ Limits (2026):
Temperature: 23 – 26 °C
Relative Humidity: 40% – 70% (Crucial to prevent mold/fungal counts exceeding 1000 $cfu/m^3$)
Air Movement: 0.15 – 0.50 m/s
Under the EECA 2024 (enforced Jan 2025), office buildings over 8,000 m^2 must display an Energy Intensity Label. Injecting hot Malaysian air is energy-expensive; we optimize this using the Affinity Laws (Cube Law).
VFD Modulation: We install Variable Frequency Drives (VFDs) on all fresh air injection fans.
The Cube Law Advantage: Fan power consumption is proportional to the cube of its speed.
The ROI: By using CO2 sensors to reduce your injection fan speed by just 20% during low-occupancy hours, you reduce its power consumption by nearly 50%. This single adjustment can shift a building from a 3-star to a 5-star BEI rating (le 90 kWh m^2 year).
Following the March 3, 2026, TR19® Air update, ventilation maintenance now requires strict verification for your "Injection" path:
Mandatory Post-Clean Reporting: You must now provide photographic evidence and Deposit Thickness Tests (DTT) to prove the injection ducts are clean.
Haze-Grade Filtration: To meet 2026 urban standards, injection units must use MERV-13 or higher filters to block PM2.5 and haze particulates.
Positive Pressure Shield: We balance the injection to be slightly higher than the exhaust. This creates Positive Pressure, which acts as an "Air Shield," pushing air out of cracks and doors to keep KL’s heat and humidity from leaking in.
