Project Overview

The existing lighting in the fire stair areas was a mixture of 36W single and double T8 fluorescent fixtures driven by electronic and magnetic ballasts. The lights operated 24/7 and had no energy saving controls. The majority of the existing car park lighting was fitted with occupancy sensors.

We were very pleased with the immediate energy savings results from this project. Our residents were very keen to try the Chamaeleon and feedback has been that the light levels were better than they had anticipated.

The Solution

452 fluorescent tubes were replaced with 313 Chamaeleon lights. A combination of wall and ceiling mount emergency 10 chip Chamaeleon lights were installed in the fire stair areas which required 24 hour lighting and a mixture of standard and emergency chamaeleon lights were installed in the car park.

Post installation lux level readings revealed an average lux level on the stair floor level in the painted basement fire stairs of 123 lux, well above the Standards requirement of 80 lux. Similarly, the average car park lux level was 71.3, almost double the standard 40 lux requirement for the car park parking bay areas.

Maintenance savings contribute to the project ROI and are calculated by costing maintenance access, no. of lamps replaced, no. of control components replaced (ballasts, starters, transformers), disposal and emergency battery costs.
