Project Overview

Hyde Park Towers is a 32 story residential tower (with some commercial space) located on Elizabeth Street Sydney, between Liverpool and Goulburn Streets. The tower was one of five pilot sites selected for the City of Sydney’s Smart Green Apartment program.

The existing lighting in these areas was a mixture of 18W and 36W single and double T8 fluorescent fixtures driven by electronic and magnetic ballasts. The original lighting installation was an emergency fluorescent fixture and a standard fluorescent fixture, providing two maintained lights at each location. The lights operated 24/7 and had no energy saving controls.

The fire stairs were alarmed and were extremely low use areas that accessed each floor and the car park, thereby ideally suited to the Chamaeleon light that operated on a standby level of light during unoccupied periods.

Testimonial

We were very pleased with the energy savings and payback results from this project and encourage other strata managers and Green Strata program participants to look seriously at the Chamaeleon Range.

8 years on at Hyde Park Towers and only 6 drivers have needed replacing. When we reached out to enLighten, they didn't hesitate to replace the drivers and renew the life of our Chamaeleon Eco's. I am delighted at the quality and longevity of this product.

Thank you enLighten for supporting your product even after 8 years and all your efforts in making a real environmental impact.

The Solution

enLighten Australia was awarded the contract to retrofit LED lighting in stairwells of the 23 residential apartment floors, 6 car park and 1 plant room levels.

156 fluorescent tubes were replaced with 82 Chamaeleon lights, generating lighting levels above Australian Standard lighting levels, delivering more than 80 lux in the fire stairs.

Electricity consumption data logged by enLighten Australia indicated a 93.55% reduction in electricity usage across the fire stairs.

The Chamaeleon installation also resulted in an average 15% increase in power factor. Power factor improvements indicate an increase in the efficiency of the lighting circuit, which translates into substantial future reductions in Ausgrid’s kVA energy demand charge.
