passive infrared occupancy sensors.
Specialised turnkey lighting project at data centre
ACTOM Electrical Products
, theACTOM group’s distribution arm
which incorporates a specialised lighting business unit, recently
completed a turnkey lighting project for South Africa’s leading
cellular network Vodacom for its Data Centre in Midrand, Gaut-
eng, involving designing and providing energy-efficient lighting
systems for the interior illumination of the building.The project,
overseen by Taemane Consulting Engineers, Vodacom’s con-
sulting electrical engineers, was executed by ACTOM Electrical
Products’ lighting business unit fromNovember 2013 to July 2014.
The lighting design technologies applied on the project com-
prise:
• A custom-designed and fabricated stainless steel suspended
light fixture supporting four large edge-lit linear LED lumi-
naires to illuminate the main reception area. It is coupled to
a daylight harvesting system designed to automatically dim
the artificial illumination during the day when the area is
sufficiently lit by natural light. The
luminaires’ on-board photocell
sensor continuously measures
the ambient light levels and
automatically ramps up its light
output to supplement the natural
light if a drop in the pre-set ambi-
ent illumination level is detected
due to overcast conditions and
automatically ramps up to its full
capacity at night
• The Data Centres occupy an open
plan area (White Space), but
each Data Centre hall requires
individual concentrated lighting
according to occupancy and is
therefore illuminated by high
efficiency T5 linear fluorescent
recessed luminaires individually
equipped with passive infrared
occupancy sensors allowing for
accurate lighting control and
switching within tight parameters
• The passages serving the Data
Centres are illuminated by high
performance IP 65 rated linear
fluorescent luminaires equipped
with electronic control gear cou-
pled to high efficiency 45 W T5
lamps and employing a corridor
dimming function – as opposed
to the on/off switching that ap-
plies in the occupancy/non-occu-
pancy applications – and control
coupled to strategically placed
sensors
• High efficiency LED luminaires
illuminate the offices
