The challenge
Legacy high-bay lighting performed poorly at low temperatures, needed frequent maintenance access in chilled spaces, and added heat load that the refrigeration plant then had to remove. Ageing HVAC controls ran fixed schedules regardless of actual occupancy.
Our approach
- 1
Audit and baseline metering to separate lighting, HVAC and refrigeration loads.
- 2
Cold-rated LED fittings specified for lumen maintenance at low temperature.
- 3
HVAC plant upgrade with modern controls, zoning and scheduling.
- 4
Rebate eligibility assessed and paperwork lodged on the client's behalf.
- 5
Verification period compared metered performance against the baseline.

Verification
- Lower lighting energy plus a secondary reduction in refrigeration duty from reduced heat load.
- Improved light levels and uniformity in chilled and packing areas.
- Fewer maintenance interventions inside cold rooms.
- Savings confirmed by metered comparison rather than estimate.
