GDS keeps Swedish Royal Philharmonic cool23 April 2014
Lighting from GDS ArcSystem installed at Stockholm Concert Hall – the home of the Nobel Prize
One of the last examples of neo-classical architecture in Sweden, The Stockholm Concert Hall was designed by Ivar Tengbom and completed in 1926. The Konserthuset comprises three separate halls, the largest of which seats 1770 people. In 1971 the venue was renovated by Tengbom’s son Anders with a focus on improving its acoustics. Home to the Royal Philharmonic Orchestra, the Concert Hall is the principal venue for orchestral music in Sweden as well as being perhaps most famous for hosting the annual Nobel Prize Ceremony.
The principal issue to be resolved in the Main Hall at the Konserthuset was the need to lower the temperature. The full orchestra on stage comprises almost 100 members and the discomfort of performing beneath the existing 68 kW of lights could no longer be tolerated. GDS, in conjunction with Anderson & Co Sweden AB, was asked to supply a solution that would take care of the problem as efficiently and quickly as possible.
GDS ArcSystem has been used throughout the hall. Above the stage, just 50 LED fixtures have replaced 160 lighting units, with the electrical load reduced from 68 kW to a mere 7.5 kW. Above the audience, 32 new units were retrofitted into the existing fixtures in a swift and straightforward operation that required no modification to either the existing fabric of the building or the units themselves.
Wirelessly controlled using the ArcMesh protocol, the system has exceeded the terms of the brief with something to spare. The management at the hall are very happy with the outcome, acknowledging not only the huge reduction in the onstage temperature but also noting a distinct improvement in the evenness of the lighting. As a consequence of the temperature reduction, the demands on the air-conditioning system in the hall are in turn mitigated, so as well as the enhanced comfort of the orchestra, there is a further clear environmental dividend in terms of efficient and sustainable energy use.
