In the commercial landscape of Kuala Lumpur and Selangor, maintaining clear escape routes is a legal and moral imperative. Commercial Stairwell Smoke-Clearance Systems are engineered to prevent the accumulation of toxic gases in vertical exit paths. Depending on the building's height and occupancy, this is achieved through either Natural Smoke Ventilation or Mechanical Staircase Pressurization.
EKG M&E Sdn Bhd provides turnkey solutions that ensure your commercial property remains BOMBA compliant, adhering to the Uniform Building By-Laws (UBBL) and MS 1472.
The choice of system is generally dictated by the building's habitable height and the feasibility of natural openings.
Used in high-rise towers, malls, and deep basements where natural airflow is restricted.
Positive Pressure (50 Pa): The system uses high-powered fans to pump fresh air into the stairwell, creating a pressure shield that physically blocks smoke from entering from the fire floor.
Velocity Protection (1.0 m/s): When a fire door is opened, the system maintains a high air velocity across the opening to "wash away" incoming smoke.
Fire-Rated Ducting: Air is delivered via 2-hour fire-rated ducts (FRL 120/120/120) to ensure system integrity during a fire.
Commonly found in low-to-mid-rise commercial buildings and shop-offices.
UBBL Clause 111 Compliance: Staircases must be provided with natural vent openings to the exterior. This typically requires an area of at least 10% of the staircase floor area or 1.0 square meter per floor.
Buoyancy Flow: Hot smoke naturally rises; these vents allow the smoke to exit the building, keeping the lower "walking zone" of the staircase clear and breathable.
As a BOMBA-Compliant M&E Specialist, EKG ensures your smoke-clearance infrastructure supports building efficiency:
TNB Energy Efficiency (Lower Operational Hz): For mechanical systems, we utilize Variable Frequency Drives (VFDs). By ensuring the ductwork is Class C Airtight, we eliminate static pressure loss. This allows the fan to hit safety targets at lower frequencies (Hz) during mandatory weekly testing, 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" during normal operations.
Prevention of "Door-Lock": If a system is over-pressurized, fire doors can become impossible to open (exceeding the 110 N limit). EKG calibrates Barometric Relief Dampers to bleed off excess pressure, ensuring safety for all occupants, including children and the elderly.
Total 3D BIM Coordination: We utilize 3D modeling to route fire-rated ducts and position vents with zero "clashes" against structural beams, sprinklers, or wet risers.
Turnkey BOMBA Submission: We perform the mandatory Pressure Differential Test, Door Opening Force Test, and Anemometer Airflow Traverse required for your annual Fire Certificate (FC) renewal.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional smoke-clearance audits and technical proposals for Grade-A office towers, luxury condominiums, and retail centers.
