Ventilation & smoke extraction in Muwaileh 

Ventilation & smoke extraction in Muwaileh: local context

Muwaileh is an inland Sharjah district near University City and the Emirates Road, combining mid-rise residential buildings, villas, schools and retail, largely developed since the 2000s. It has grown quickly as a more affordable family area with good access to both Sharjah and Dubai. New mid-rise plots continue to be built next to occupied buildings. Its commercial strips and schools serve a large residential catchment, and plots continue to be released for new mid-rise buildings and community facilities.

• Mid-rise residential buildings commonly use air-cooled chillers or VRF on the roof, which must be derated for inland summer temperatures and spaced to avoid hot-air recirculation.
• Desert dust affects condenser coils and filters, so maintenance access is planned into roof layouts.
• Many plots back onto busy service roads near the Emirates Road and University City Road, so crane positions, deliveries and concrete trucks are coordinated with neighbouring sites and school traffic.

Building types we serve in Muwaileh

For mid-rise residential and mixed-use buildings, the work concentrates on compact plant on the roof, car-park ventilation in podiums, metered apartment DBs and tight ceiling voids that make coordination drawings decisive.

Scope of work

• Smoke exhaust fans, smoke dampers and make-up air paths for atria, malls and corridors as required by the strategy.
• 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.
• Natural ventilation openings, automatic smoke vents and their actuators where the fire strategy relies on them, tested to open on alarm.

Systems we install

• Car park jet fans and main extract fans
• Stair and lobby pressurisation fans

UAE site and climate challenges

• Pressurisation fans draw outdoor air that may be very hot and dusty, so intakes are positioned away from smoke exhaust discharges and fitted with sand louvres to keep fans and dampers working reliably.
• Strong winds and sand can jam relief dampers and louvres, so these are checked during commissioning and included in periodic maintenance to ensure they open and close freely on demand.
• Fan redundancy and secondary power arrangements, which add cost but determine how robust the smoke control system remains if one fan or one supply fails during a fire.
