Description
Located in Cardiff Bay, in Cardiff UK is a multi-storey car park that has 1237 car parking spaces. Due to the high profile of the Cardiff Bay development which includes the Welsh Assembly and the Wales Millennium Centre, the new multi-storey car park which is owned by Knight Frank LLP needed to integrate with this dynamic area. To achieve this, the architect Scott Brownrigg Limited and the lighting designer Paul Traynor PLDA of Light Bureau developed the idea of 6 wave shape structures to be installed on the long façade of the car park. The steel and fabric structures were manufactured and installed by Base Structures Ltd. The intention of the 3-dimensional wave shapes is to link the car park with the original purpose of Cardiff Bay and its connection with the sea. Another visual link with the sea was the requirement for the night time appearance of the wave to be lit using a combination of blue and white lighting. Particular consideration was taken by Light Bureau (Lighting
Consultant) in the specification of the fittings and their location due to the close proximity of the very busy entrance to the A4232 Butetown Tunnel.
Light Bureau recommended Control Lighting's involvment in this project due to their expertise to facilitate the correct control solution for a unique project such as this. To fulfil the lively night time appearance of the waves, individual control was required per lamp on each of the lighting fixtures that were part of the wave lighting scheme. The chosen lighting fixtures were the twin Norka ERFUT:4426.0 SP surface mounted IP65 T8 fluorescent fittings and with Osram Quicktronic QTI-DALI 1 x 58 DIM DALI dimmable ballasts and Osram 58W linear triphosphor T8 lamps. Each fitting comprises of a blue and a white T8 fluorescent tube and each fitting was modified to take two individual ballasts for individual lamp control.
When designing the lighting control solution for this project two key elements had to be factored in. The first being the sheer quantity of individual control required for 472 fluorescent ballasts on a single control system; and the second being to be able to program the visual effects of the sequences in a graphical format and not a conventional “channel = level arrangement”. To achieve these fundamentals, Control Lighting combined the use of a sophisticated DMX visual time line based control playback unit in addition to converting DMX into 12 separate DALI universes.
To minimise on the cable installation the fittings were specified utilising the DALI protocol which enabled a better level of individual control and reporting than other protocols designed for fluorescent ballasts. To achieve the smooth conversion between DMX to DALI interface units, Control Lighting specified and installed Dynalite DDBC100 units at each row of fittings.
Careful consideration was taken on the timings of the sequences as well as the impact of the ambient temperature on the lamps and the DALI ballasts. The sequences are recalled automatically using astronomical time clock commands, with manual override facilities also included. The visual result details movement of light intensity utilizing the white and blue fittings across the wave structures in both linear patterns as well as dynamic spiral configurations.
