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. The developer and the client insisted, from the

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
