In 2026, Minimum Outdoor Air Intake Compliance is the primary legal benchmark for mechanical ventilation in Malaysia. Under the DOSH ICOP IAQ 2026 (Industry Code of Practice on Indoor Air Quality) and the EECA 2024 (Energy Efficiency and Conservation Act), building owners are no longer just encouraged to provide fresh air—they are legally mandated to verify and log it for federal audits.
At EKG M&E, we apply 34 years of mechanical engineering to ensure your intake rates meet the 10 l/s per person threshold while maintaining the energy efficiency required for your 2026 Building Energy Index (BEI) rating.
To pass a DOSH 2026 audit, your fresh air injection system must satisfy these three critical requirements:
The 10 l/s Mandate: Every occupied space must receive a minimum of 10 liters per second (l/s) of fresh outdoor air per person. This is the absolute minimum required to prevent the buildup of airborne pathogens and CO2.
The 1,000 ppm CO2 Ceiling: Carbon Dioxide is the legal "Proxy" for ventilation. If your indoor CO2 levels exceed 1,000 ppm, your building is officially considered "Under-Ventilated" and non-compliant.
MERV-13 Filtration: Following 2026 updates, all outdoor air intakes in urban Kuala Lumpur must utilize MERV-13 or higher filtration to block haze particulates (PM2.5) before they are injected into the building.
The EECA 2024 (enforced Jan 2025) presents a challenge: how do you inject massive amounts of fresh air without spiking your utility bill? We solve this using Demand-Controlled Ventilation (DCV).
Variable Frequency Drives (VFDs): We install VFDs on all intake fans to modulate speed based on actual occupancy.
The Cube Law Advantage: Fan power consumption follows the Cube Law.
The Math: By using smart sensors to reduce your intake fan speed by just 20% during low-occupancy hours, you reduce its power consumption by nearly 50%. This allows you to stay compliant with DOSH while hitting your EECA energy targets.
Compliance is not just about having a fan; it is about proving it works.
Flow Balancing & Verification: We use digital flow hoods to provide the NIST-traceable airflow reports required for your 2026 federal filing.
FFT Vibration Audit: We perform Fast Fourier Transform (FFT) analysis on intake units to ensure that high-pressure fresh air injection doesn't cause structural rattles or premature motor failure.
Intake Location Audit: We verify that your outdoor air intake is located at least 10 meters away from cooling towers or exhaust vents to prevent "short-circuiting" contaminated air back into the building.
| Metric | 2026 Minimum Standard | EKG M&E Compliance Task |
| Fresh Air Flow | 10 l/s per person | Vane Anemometer Calibration |
| CO2 Levels | < 1,000 ppm | Smart Sensor Logging & BMS Link |

34 Years of Engineering Depth: We understand the complex "Pressure-vs-Volume" physics required to hit compliance targets in tropical climates.
Certified Reporting: We provide the Indoor Air Quality (IAQ) Assessment Reports required for Registered Energy Manager (REM) and DOSH inspections.
Turnkey Remediation: If your building fails an audit, we handle everything from VFD retrofits to duct sealing to bring you back into compliance.
