Project Overview

The car park and fire stair lighting upgrade was part of a wider energy management project that was instigated by Brett Thiedeke. Brett has been the site's electrical contractor for 10 years including planned & reactive electrical maintenance, which enabled him to develop a strong understanding of the building's operating costs and opportunities for improvement.

The extensive project which also included HVAC controls, data logging, car park exhaust fan timer clocks, garden & lobby lighting upgrades was recognised as State Energy Efficiency Project Winner by Master Electricians QLD in October 2015 and NATIONAL winner a month later.


We are very pleased with the Chamaeleon light installation in the 4000m² underground car park of our South Brisbane apartment complex. In addition to the significant energy cost savings, the area is noticeably cooler.
