The Common Area Lighting Problem in Sydney Strata

Electricity costs in Sydney strata buildings have risen sharply over the past three years. For many OC committees, common area lighting — lobbies, corridors, car parks, stairwells, external paths — represents 40-60% of total building electricity consumption. The frustrating reality is that most of this lighting runs on fixed schedules that were set during building commissioning and never adjusted, meaning lights run at full brightness for 18+ hours a day regardless of actual occupancy.

What C-Bus and Dynalite Can Actually Do for Your Levy

Buildings with existing C-Bus or Dynalite systems have a significant advantage: the infrastructure for intelligent lighting control already exists. The question is whether it's being used correctly. In our experience working with Sydney strata buildings, most are using less than 30% of their system's capability. Common underutilised features include:

  • Occupancy-triggered scenes — dim corridors to 20% when unoccupied, bring to 100% on motion
  • Daylight harvesting — reduce artificial lighting in lobbies as natural light increases
  • Time-of-day scheduling — reduce car park lighting levels from midnight to 5am
  • Astronomical clock integration — external lighting switches automatically at true sunrise/sunset
  • Energy reporting — identify which circuits are drawing the most power and when

Real Numbers: What Sydney Strata Buildings Are Saving

Across the Sydney strata buildings we've optimised, common area lighting energy consumption has reduced by 35-65% following C-Bus or Dynalite reprogramming — without any hardware upgrades. A typical 60-unit building in Sydney's Inner West spending $18,000 per year on common area electricity can realistically reduce this to $9,000-$12,000 with intelligent control optimisation. That saving flows directly to the owners through reduced levies.

The LED + Control Combination

If your strata building still has fluorescent or halogen fittings, combining an LED upgrade with C-Bus or Dynalite reprogramming delivers the best return. LED replacements alone typically save 40-50% on lighting energy. Combine that with intelligent scheduling and occupancy control, and total savings of 70-80% against baseline are achievable. For a building with $20,000 in annual lighting energy costs, payback on a combined LED and control upgrade is typically 2-4 years.

Getting Your Strata Building Optimised

The first step is a lighting control audit. We review your existing C-Bus or Dynalite programming, identify schedules that are wasting energy, map occupancy patterns to proposed new scenes, and provide a written report with projected energy savings and payback periods. This gives the OC committee the evidence they need to approve the works. Sydney Automation Co. works directly with strata managers and OC committees across Greater Sydney.
