Parking lot exhaust ducts

Parking Lot Exhaust Ducts by EKG M&E Sdn Bhd

In the urban developments of Kuala Lumpur and Selangor, parking lot exhaust ducts are the primary mechanical conduits for both daily environmental health and emergency fire safety. Because parking structures (especially subterranean ones) are enclosed, they lack natural ventilation. These ducts are responsible for flushing out toxic Carbon Monoxide (CO) and, in the event of a fire, performing high-volume Smoke Spill extraction.

EKG M&E Sdn Bhd specializes in the engineering, 3D coordination, and installation of these heavy-duty networks, ensuring full compliance with MS 1780, UBBL, and BOMBA standards.

The Dual-Force Engineering Strategy

A professionally installed exhaust duct network is designed to manage two very different airflow regimes using a single set of fire-rated conduits.

1. Daily Pollutant Extraction (CO Mode)

• Demand-Controlled Response: The ducting is linked to distributed CO sensors. Through a Variable Frequency Drive (VFD), the system modulates fan speed based on real-time vehicle traffic.

• Stagnant Zone Prevention: Using 3D BIM Coordination, we position extraction grilles at both high and low levels. This is critical because while CO has a similar density to air, heavier particulates and "cold" smoke tend to pool at lower levels.

2. Emergency Smoke Spill (Fire Mode)

• High-Temperature Endurance: Upon a fire signal, the system extracts superheated gases (up to 400°C).

• FRL 120/120/120 Integrity: We utilize 1.2mm heavy-gauge galvanized steel (G.I.) encased in BOMBA-approved fire-rated boards or wraps. This ensures the duct remains structurally sound and insulated for at least 2 hours during a fire event.

Critical Operational & Energy Benefits

As a specialized M&E contractor, EKG ensures your exhaust infrastructure is optimized for performance and cost:

• TNB Energy Efficiency (Class C Airtightness):

  Leaky ducts force extraction fans to work harder. By ensuring a Class C Airtight installation with certified intumescent sealants, we eliminate static pressure loss. This allows your fans to hit safety targets at lower frequencies (Hz), directly reducing your monthly TNB electricity bill.

• EECA 2024 & Building Compliance:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be optimized for minimal waste. Our precision-engineered systems prevent energy "bleeding" and ensure your Building Energy Index (BEI) remains within green compliance levels.

• Space Optimization:

  KL parking lots often have low ceiling clearances. We utilize 3D modeling to route flat-oval or rectangular duct profiles that maximize vehicle clearance while maintaining the required airflow volume for smoke extraction.
