November 2009 – High-performance buildings are more than mere assemblies of energy-thrifty components – genuine efficiency is only achieved when all parts of the building fabric are integrated seamlessly under one design purview. JOHN POWER went in search of integration perfection and found it at the new Blackmores Campus office and distribution centre in Warriewood, Sydney.
The new $32 million, 14,000-square-metre Blackmores Campus, recently completed for the well-known Blackmores health product, vitamin and supplement firm, is the building equivalent of a healthy body – with all parts working in harmony to create a coherent, balanced whole.
SEEING THE LIGHT
Tim Shotbolt, AECOM’s associate director, says he is particularly proud of the effectiveness of the building’s lighting systems.
“There is much more to lighting than the energy consumed per square metre,” he says. “Blackmores’ new office facilities have an optimum orientation to take advantage of natural light. Natural light includes both sunlight and daylight where sunlight is the direct light from the sun and daylight is the more diffuse light from the sky, clouds etc.
Shotbolt says the main office lighting consists predominantly of modules of suspended low-profile linear fluorescent luminaires (light fittings). These Fagerhult Ten° Line luminaires produce upward light that bounces off the ceiling, which helps make the space feel bright and light. The upward component is a cooler bluish white light similar to that from the midday sky and the downward component is a warmer light similar to sunrise and sunset. High-efficiency T5 fluorescent lamps run on TridonicAtco dimmable electronic DSI control gear, which responds to signals from a C-Bus control system.
There are zones adjacent to the north-facing winter gardens and also adjacent to the south-facing windows. These perimeter zones have daylight sensors that are linked to the C-Bus control system, the perimeter zones being controlled separately to the central zone. According to the available sunlight and/or daylight, the office lighting in the perimeter zones will dim automatically to minimise energy consumption.
