Case Study: Austria Center Vienna
IST’s iDrive® White Knight 36 and Thor 36 centralised LED drivers have recently been included in a full Ethernet-based lighting refurbishment within the impressive Austria Center Vienna (ACV). Delivered by IST’s partner in Austria, Leman GmbH has over 40 years’ experience in delivery of technical services across a wide variety of settings globally, such as event, film and TV productions, as well as the design and implementation of architectural lighting.
The ACV is one of Europe’s largest and most modern conference and exhibition centres and is used for international conferences, corporate events and concerts. Linked internally to the adjacent Vienna International Center, the campus forms part of the UNO-City, which is an imposing site located on the north bank of the River Danube housing several international organizations, including one of the four United Nations Headquarters. About 5,000 people work at the site, which is constantly a veritable hub of international activity.
With ceiling heights of up to 15m, the ACV requires a substantial number of luminaires to illuminate the space sufficiently. Installing single channel LED drivers next to luminaires high in the ceilings proved to be a massive stumbling block at the planning stage, due to the potential of generating significant costs for installation, commissioning, not to mention the operational headache for future maintenance and the associated spiralling costs.
The client therefore sought an energy efficient lighting solution for which power could be supplied at a distance from the luminaires from a centralised location, in order to significantly simplify installation, commissioning and allow easy access for any future maintenance.
iDrive® centralised LED drivers were absolutely ideal for the refurbishment of this highly impressive international conference centre. With each individual centralised, rack-mounted LED driver capable of powering up to 36 luminaires from a single point, the drivers could be installed at ambient temperature up to a distance of 100m from the lighting fixtures, without compromising on the power supplied to each luminaire. Installing LED drivers at ground-level in ambient temperature not only serves to significantly prolong the lifetime of the LED drivers, but also vastly simplifies installation, commissioning and any future maintenance required for the project.
In addition to its unique rack-mounted, centralised design, the iDrive® centralised LED driver range boasts the smoothest dimming on the market and provides totally flicker-free, healthy lighting, which is recognised as being of critical importance for the health and wellbeing of workers and people in their everyday environments.
Initially, 55 x iDrive® White Knight 36 and 14x iDrive® Thor 36 were installed in Halls A, B and C. The 4312m² space can either be configured as independent halls, or combined as one to create a huge conference hall capable of seating 4,320 people.
The 36 channel iDrive® White Knight 36 models are used to control approximately 800 x 32W downlights and 415 x 30W-40W high bay luminaires. The Thor 36 LED drivers are controlling approximately 1100m of flexible RGB tape and a further 150m of flexible white LED tape, which gives the room a really modern ambience and allows for the mood of the space to be dramatically changed using colour variations, according to the event it is hosting.
A further 6 x iDrive® White Knight 36 are installed in Hall N and 19 x iDrive® White Knight 36 have been installed in Halls D, G and K to power 442 x downlights (33W).
The iDrive® LED drivers are all controlled by DMX, ARTNET and sACN. BMS is also configured into the scheme for the emergency lighting Dimming and colour changes can be conveniently made via iPad.
Ethernet connectivity was chosen for the control solution because the client wanted to use an IP-based control network to facilitate the integration and control of the large number of luminaires, as well as providing the client with a future-proof solution when new halls and luminaires are added to the system.
