What Is a Brownfield Lighting Upgrade?
A brownfield lighting upgrade refers to retrofitting modern automation into an existing, occupied building — as opposed to a greenfield new build where automation is designed in from scratch. This scenario is extremely common across commercial towers, strata complexes, warehouses, and institutional facilities built in the 1990s and 2000s across Greater Sydney, where lighting was originally controlled via simple manual switchboards, timer relays, or basic photocell sensors.
The Core Challenge: Existing Infrastructure
Brownfield sites present unique engineering constraints. Existing conduit runs, circuit wiring, and switchboard configurations cannot simply be ripped out without massive disruption to occupied tenants and facilities. The solution requires a staged, intelligent retrofit strategy that layers modern C-Bus or Dynalite automation intelligence over the existing 240V wiring infrastructure with minimal disturbance.
Our Staged Brownfield Retrofit Approach
- Circuit Audit: We map existing lighting circuits, identify load types (LED, fluorescent, HID), and determine optimal relay and dimmer sizing for the new C-Bus or Dynalite enclosures.
- DIN-Rail Enclosure Integration: New C-Bus SpaceLogic relay and dimmer modules are installed within existing switchboard enclosures, utilizing existing wiring where possible to minimize rewiring costs.
- DALI-2 Sensor Overlay: Modern DALI-2 motion and daylight sensors are installed in occupied spaces without requiring new conduit — connecting via existing Cat5e or dedicated DALI bus cable run overhead.
- Head-End Commissioning: Full C-Bus Toolkit or Dynalite EnvisionProject database programming, schedule automation, and DALI emergency lighting integration is executed by our accredited specialists.
