Coordinating ventilation across multiple zones

Large-scale retail and residential projects create unique installation demands. Contractors must coordinate ventilation across multiple zones while maintaining safety standards. The underground car park required specialised smoke management, while residential areas needed natural AOV solutions.

Each zone presented height restrictions, access limitations, and coordination requirements. Because of these constraints, installation crews needed equipment designed for rapid deployment. Traditional multi-vendor approaches would have created coordination bottlenecks and extended the installation timeline.

Technical solution details

For the car park ventilation system, the team delivered 40 jet fans and 2 large extract shafts. The jet fans include reliable AUT 400 basic jet fans and compact CGF 500 slimline jet fans, selected for areas with limited height to simplify installation.

Equipment selection prioritised installation efficiency through factory preparation and integrated components:

  • Pre-assembled extract shafts minimise field assembly time because factory-built units arrive ready for connection
  • Compact jet fans suit restricted ceiling heights common in car parks, so installation crews avoid complex modifications
  • Integrated silencer packs come pre-fitted to reduce on-site acoustic work and eliminate separate acoustic installations
  • Purpose-built frames for acoustic applications arrive fully assembled, eliminating field fabrication

These design decisions reduced on-site labour requirements by approximately 40% compared to traditional component-by-component installation. The car park extract shafts feature 2 pcs ACN 1400 and 2 pcs ACN 1600 smoke extract fans, delivering a combined extract rate of more than 500,000 m³/h. Large silencer packs come pre-fitted to reduce on-site installation time further.

The complete system operates through an integrated CO and NOx detection system. Separate smoke clearance and gas detection systems were installed for the service yard and loading bay areas. Loading bay extract fans arrived in purpose-built acoustic frames, fully factory-assembled, so installation teams simply positioned and connected the units without additional assembly work.

All 16 smoke shaft systems installed in firefighting lobbies and escape stairs connect through a sitewide network. This provides clear status indication at the management suite, ensuring straightforward operation and immediate detection of system activation.

Network integration delivers operational benefits. Centralised monitoring reduces maintenance visits and provides immediate fault detection. The system also simplifies commissioning because all zones can be tested and verified from a single location, reducing the time engineers spend accessing individual stair shafts.

Single-source responsibility eliminates coordination issues

NOVENCO Building & Industry provided turnkey ventilation solutions for the entire development. The scope included design, supply, installation, and commissioning of all smoke ventilation systems. This covered mechanical smoke clearance for the two-level underground car park, loading bay, and service yard, plus all natural and mechanical AOV stair systems.

This integrated approach eliminated coordination issues between vendors, reducing installation time and simplifying project management. Single-source responsibility meant one contact for design queries, delivery scheduling, and technical support.
