HWT Building - Ernst &Young Tenancy
8 Exhibition Street, Melbourne – a building of elegant architecture – was the home of the Herald & Weekly Times from 1923-1995. Recently, it underwent a $140 million reconstruction that included a new 34 storey tower and the conversion of the former four storey offices of the HWT into a Soho-luxury residential complex. The iconic building still retained many of its original, distinguishing features, including the former radio masts and the famous Herald Sun neon sign on the roof.
Global finance leader Ernst & Young put their hand up as anchor tenant
of the commercial building, which comprises of 45,000m2 NLA of commercial space.
As part of the new tenancy fit-out - courtesy of construction giant Bovis Lend
Lease - Ernst & Young required a 4.5 star energy rating achieved by a comprehensive
energy management through a sophisticated lighting control system. Electrical
engineers / designers for the project Norman, Disney & Young, offered an
open specification that was won by Electrical Contractors, Apps Electrics. Norman,
Disney and Young had two stipulations as to what lighting control system they
sought; it had to be done quickly, and most importantly, it had to work. Therefore,
Lightmoves were invited to supply the Dynalite system for energy management
and lighting control to the 14 floors of the building that Ernst & Young
occupy.
Lightmoves Technical Director Andrew Sherar and project manager Haydn Brennan
met with staff from Norman, Disney & Young to further discuss the specified
requirements of the system. Daylight harvesting – maximising the use of
natural light and the reduced dependence on artificial light – was an
important aspect to the overall system and was achieved through the use of daylight
sensors. A further vital element in the system was the ‘after hours’
component. Many lighting control systems are considered vulnerable during ‘after
hours,’ especially when something out of the ordinary takes place. However,
it is during these periods when the Dynalite system shows how intricate and
reliable it can be. Once the ‘after hours’ feature has been enabled,
the lighting system is run purely off sensors. If, for example, an employee
is just venturing back to their desk quickly to grab a forgotten item, the motion
sensors will light a direct path for them and remain on for a ten minute period.
If the employee plans to stay longer, they can override the sensors via a touchscreen
and type in the specified timeframe that they require the lighting to be operational.
The real benefit to a system like this is the centralised control. Whilst each touchscreen and panel allows the individual user local control, the Building Manager has full access to the system via a computer interface. From here, they have master control over the entire 14 floors of automation.
However, it was levels 23 &
24 - the two meeting room floors - where the control system demonstrated its
full flexibility. Here the control system was asked to interface with and create
simple control for the air-conditioning, the audio / visual and the motorised
curtains.
Battling a very tight deadline, Apps and Lightmoves were able to install and commission the extensive number of required devices that included over 1000 channels of dimming (fluorescent & ELV), 300 push-button panels, 270 motion sensors and close to 40 touch screens.
This project is a perfect example of the comprehensive economical and environmental benefits that can be obtained through a well designed and implemented Energy Management through Lighting Control system.
