In the subterranean architecture of Kuala Lumpur and Selangor, basement carparks are enclosed environments that lack natural airflow. Without a robust ventilation system, these areas quickly accumulate toxic vehicle emissions and become high-heat traps during a fire. Basement Carpark Ventilation is a dual-purpose mechanical strategy designed to manage daily Carbon Monoxide (CO) levels and perform emergency Smoke Spill extraction.
EKG M&E Sdn Bhd specializes in engineering these high-performance systems to ensure full compliance with MS 1780, BOMBA regulations, and the Uniform Building By-Laws (UBBL).
A professionally designed carpark system must transition seamlessly between two distinct operational states.
The primary goal is to maintain breathable air quality by removing hazardous vehicle exhaust (CO, NOx, and PM2.5).
CO Sensor Integration: Our systems utilize distributed Carbon Monoxide sensors. When levels exceed safe thresholds (typically 25-50 ppm), the system automatically activates or ramps up fan speeds to flush the basement.
Supply & Exhaust Balance: We balance fresh air intake with mechanical exhaust to ensure no "stagnant pockets" of air occur, protecting both building occupants and security personnel.
In the event of a vehicle fire, the system switches to its maximum capacity to protect lives and the building structure.
Visibility & Tenability: The system extracts hot smoke at a high rate to maintain a clear "smoke-free" layer above head height, allowing occupants to see escape exits.
Negative Pressure Zone: By creating negative pressure in the fire zone, the system prevents smoke from migrating into elevator lobbies or escape stairwells.
As a specialized M&E contractor, EKG ensures your ventilation infrastructure is optimized for the long term:
TNB Energy Efficiency (VFD Modulation):
Running large carpark fans at full speed 24/7 is a massive energy drain. We utilize Variable Frequency Drives (VFDs) that modulate fan speed based on real-time CO levels. This can reduce your monthly TNB electricity bill by up to 50% compared to constant-speed systems.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be energy-optimized. Our Class C Airtight ducting prevents "air bleeding," protecting your Building Energy Index (BEI).
FRL 120/120/120 Fire-Rated Ducting:
Since carpark ducts serve as emergency smoke routes, we utilize 1.2mm heavy-gauge G.I. encased in BOMBA-approved fire boards. This ensures the system remains functional for at least 2 hours during a high-heat fire event.
| Feature | Standard Ventilation | EKG Carpark Ventilation System |
| Material Gauge | 0.5mm – 0.8mm GI | 1.2mm (BOMBA Standard) |
| Control Logic | On/Off Switch | CO Sensor & Fire Alarm Interlocked |
| Fire Rating | None | Mandatory 2-Hour (FRL 120/120/120) |
| Fan Type | Ambient Air Fans | High-Temp Smoke Fans (300°C/2Hrs) |
| Energy Strategy | Constant Volume | VFD-Driven Demand Control |
Total 3D BIM Coordination: Basement ceilings are crowded with sprinklers, plumbing, and cable trays. We utilize 3D modeling to route large-diameter ventilation ducts with zero "clashes," preserving maximum headroom for transport vehicles and SUVs.
Turnkey BOMBA Submission: We perform the mandatory Smoke Tests, Airflow Traverse, and Sensor Calibration required for your annual Fire Certificate (FC) renewal.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional audits and technical proposals for shopping malls, office towers, and luxury residential basements across Malaysia.
