In the safety architecture of Kuala Lumpur and Selangor, staircase vents serve as the lungs of the evacuation route. Depending on the building's height and design, these vents either facilitate Natural Ventilation (passive) or act as the discharge/relief points for Mechanical Pressurization (active).
EKG M&E Sdn Bhd provides specialized venting solutions that ensure your staircase remains a "breathable sanctuary," fully complying with the Uniform Building By-Laws (UBBL) and BOMBA standards.
For low-to-medium rise buildings, natural vents are the primary method for clearing smoke.
UBBL Clause 111 Compliance: Staircases must be provided with natural vent openings to the exterior. Generally, these must have an aggregate area of not less than 10% of the staircase floor area or 1.0 square meter per floor.
Fixed vs. Operable Louvers: We install weather-proof fixed louvers or automatically operable vents that open upon a fire alarm signal, allowing hot smoke to buoyant-lift and exit the building naturally.
In high-rise buildings where mechanical pressurization is used, vents act as "safety valves."
Preventing "Door-Lock": If a pressurization fan is too powerful, the air pressure can make fire doors impossible to open. We install Barometric Relief Dampers that automatically open when pressure exceeds 50 Pa, ensuring the door-opening force stays below the 110 N (Newton) limit.
Fire-Rated Integration: These vents are often connected to 2-hour fire-rated ducts (FRL 120/120/120) to ensure that a fire on one floor cannot "jump" into the staircase through the relief path.
As a BOMBA-Compliant M&E Specialist, EKG ensures your venting infrastructure supports building efficiency:
TNB Energy Efficiency (Leakage Control):
Poorly sealed vents allow conditioned building air to leak out 24/7. By using Low-Leakage Motorized Vents, we ensure the staircase is hermetically sealed during normal operations. This reduces the load on your primary AC system, directly resulting in a lower monthly TNB electricity bill.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, every mechanical opening in a building must be optimized. Our precision-engineered vents prevent energy waste while ensuring life-safety systems are ready for audit.
Acoustic Comfort:
Properly tuned vents eliminate the high-pitched "whistling" sounds often heard in high-rise stairwells caused by air forcing itself through door gaps in unbalanced systems.
| Feature | Natural Ventilation Vents | EKG Mechanical Relief Vents |
| Building Type | Low-to-Mid Rise | High-Rise / Basements |
| Activation | Always Open / Fusible Link | Automatic (Pressure-Sensing) |
| Pressure Control | None | Maintains 50 Pa Shield |
| Fire Rating | Standard Louvers | Mandatory 2-Hour Rated |
| BOMBA Required | UBBL Compliance | Mandatory for Fire Certificate |
Total 3D BIM Coordination: Vents must be placed strategically to avoid "re-entry" of smoke into other floors. We utilize 3D modeling to coordinate vent placement with the building's facade and other services.
Turnkey BOMBA Submission: We perform the mandatory Door Opening Force Test and Pressure Differential Test required for your annual Fire Certificate (FC) renewal.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional safety audits and installations for Grade-A office towers, luxury condominiums, and hospitals across Malaysia.
