Ventilation & smoke extraction in Aljada 

Ventilation & smoke extraction in Aljada: local context

Aljada is a large master-planned community being built near University City and the Emirates Road, with mid-rise apartments, townhouses, retail and leisure in phases since the late 2010s. It is one of Sharjah's biggest new developments and remains under active construction. The development combines residential neighbourhoods with retail, leisure and community buildings, delivered in phases by a single master developer, so infrastructure, utilities and access routes evolve as each phase is completed and handed over.

• Phased community infrastructure means utility connections may be available at different times, so temporary power and testing arrangements are planned in advance.
• Inland heat and dust demand derated air-cooled plant and protected intakes.
• Mid-rise buildings and townhouses typically use VRF or air-cooled chillers, with plant locations fixed by master plan guidelines on screening and noise.

Building types we serve in Aljada

For malls and retail centres, the work concentrates on large-volume air handling, tenant-ready chilled water or refrigerant capacity, smoke extraction for atriums and car parks and food-court exhaust.

Scope of work

• Installation of car park ventilation with jet fans, main extract fans and CO or NO2 sensors controlling normal ventilation.
• Fire-rated cabling and secondary power arrangements for smoke control fans so they operate during a fire.
• Interface wiring with the fire alarm system for zone-by-zone activation and fan status feedback.
• Cause-and-effect testing, door opening force checks and Civil Defence witnessed tests.

Systems we install

• Car park jet fans and main extract fans
• Smoke exhaust fans rated for high temperature

UAE site and climate challenges

• Rooftop smoke fans and motors are exposed to extreme heat and direct sun, so motors, enclosures and fire-rated cabling are selected for high ambient conditions as well as smoke temperature.
• Basement car parks in coastal towers can see condensation on cold surfaces when hot humid air is pulled in at high rates, so supply air paths and ramp openings are reviewed to limit wet floors and corrosion of jet fans.
• Integration with BMS for monitoring, which helps maintenance teams identify failed fans, dampers or sensors without taking life safety control away from the fire alarm system.
