ROI: 2.4 years
Adelaide Consultants Sustainable Focus advised SA Pathology on energy efficient lighting upgrade options for the existing single and twin T8 fluorescent tube lighting in the fire stairs and plant rooms of their Adelaide clinical laboratory & research facilities. The Chamaeleon III light was selected over LED battens with microwave sensor due to its energy savings and the additional features of self test.
Energy & maintenance over 10 years
Savings per fitting: $188 pa
Avg annual energy & maintenance saving over 10 years
66 standard & emergency Chamaeleon IIIs were installed, replacing 103 fluorescent fittings (including 27 non maintained 10W T8 battens) & meeting the 80 lux requirements for AS 1680 compliance.
The Chamaeleon III's additional self test features enables each emergency light to run a monthly battery discharge test without interrupting the normal operation of the light. The test status is visible via a multicolour indicator & allows the building manager easier scheduling of battery changeover within the 6 monthly reporting requirements.
The project offered an attractive payback as there was a 1 for 2 replacement of light fittings in the fire stairs which halved the number of luminaires, resulting in ongoing energy and maintenance savings.
The project drivers were to reduce energy and maintenance costs and to reduce the site’s energy consumption for SA Health's internal efficiency reporting requirements.
Chamaeleon III Settings
The standard settings of 100% full light output and 2.5% light output in standaby (consuming 4-5W) were applied. The timer control on the microwave motion sensor was increased from the standard 15 seconds to 90 seconds to allow for the movement of groups of people transitting through the fire stair during office house of 9am & 5pm.
