was maintaining sufficient task light at desk level,
a DALI lighting system with light and movement
sensors was installed to control the lighting levels
and augment daylight when needed. Each lamp is
individually addressable with data from the iBMS
constantly adjusting its lighting level through the
course of the day.
In addition to controlling the lighting, the sophis-
ticated building management system controls other
systems to best save energy and provide in-depth
reporting. It monitors the external weather and
sunlight conditions, automatically controlling the
blinds to maximise the natural daylight penetration
whilst limiting solar heat gain and glare. The data
collected allows the tenant to fine-tune the building
energy use over time.
The lighting control that is possible using the
DALI protocol offers the ability to support mood
lighting by varying brightness, colour and colour
temperature across large lighting arrays and to
provide pre-set scene control in specific areas
such as the auditorium and the meeting pods. The
protocol can also report on the status of ballast or
lamp failures.
The external lighting of the building is subtle,
both to save energy and to maintain an effect that is
restrained and elegant.The columns at the entrance
are illuminated top and bottom and the fountains
are simply illuminated to create an appealing ef-
fect. External fittings on the piazza provide light for
safety and to extend enjoyment of the space after
sunset. Also in the public realm, the lighting of the
old ‘cyclone’, a feature retained from the historical
Grain Silo building adjacent to No.1 Silo, offers an
effective moment of attention on historical detail.
All external light shines to earth and light spill
from the building is controlled to prevent light pollu-
tion. What light is visible creates a warm nocturnal
ambience.
