Iora Apartments participated in North Sydney Council's My Green Apartment program, which identified retrofit of car park & fire stair lighting as a priority to deliver energy & maintenance savings. The Chamaleon LED lighting upgrade project payback was further strengthened through the generation & sale of Energy Savings Certificates, delivering $8,700 to the Executive Committee under the NSW Government's Energy Savings Scheme.
(Nov 2014 - July 2015)
An 8 chip emergency Chamaeleon light operating on full light output (28W) and standby (7.5w) was selected to replace twin 18W fluorescent battens that operated 24/7 without any control within the enclosed fire stairs. The integrated motion sensor and a combination of 10 chip emergency & standard Chamaeleon lights for the car park entry, ramps & driveway areas replaced twin 36W fluorescent battens, of which around half had been delamped.
For the individual garages, a Chamaeleon light with no standby light output was selected.
We developed a thorough return on investment (ROI) spreadsheet, which took into account existing & replacement lighting types, hours of operation, use of sensors and site electricity tariff data. In the back end we inputted cost data of emergency light battery replacements, call out rates and lamp replacements.
