A standard & emergency Chamaeleon LED light retrofit of T8 fluorescent batten lighting in the underground car park & fire stairs of the 93 apartment complex on the Brisbane River contributes to a National Energy Efficiency Award win for electrical contractor Briett Thiedeke. Combined with a wider scope of upgrade works including lifts, exhaust fans, HVAC, pool pumps, garden & pool lighting a 30% reduction in TOTAL common area electricity usage was achieved from 2012-15.
No failures were recorded at the first 6 monthly emergency lighting battery discharge test since the lighting upgrade, which has delivered an annual $10K saving in replacement parts & labour.
The Owners Corporation received an Energex Positive Reward payment of $1771, in recognition of the site's contribution to peak load reduction across its network.
