Zumtobel Lighting makes waves at new City office development
Zumtobel Lighting has collaborated with Arup Associates, SAS International and Stortford Interiors to create a striking sculptural ceiling for the entrance to new City of London office development Ropemaker Place, owned by British Land Company.
The sculptural, waveform-shaped ceiling system was a refinement of similar ceilings designed in collaboration with Zumtobel in previous British Land projects in the City. The aim was to create an direct/indirect lighting source with an acoustic performance, while providing a strong visual element in the 10.5m-tall corner entrance foyer. It also acts as a visual focus when viewed externally from City Point Plaza, Ropemaker Street and The City.
‘The appearance of the ceiling is that of a series of illuminated vaulted waves flowing into the interior, so that the volume of the space appears to be expanded by the uplit waveform surfaces,' said Arup architect and director Mick Brundle.
The system forms both the main internal ceiling surface and the external canopy surface, so that there is visual continuity between the interior and exterior systems.
The ceiling system comprises pre-formed white PPC micro-perforated steel sheeting with a white tissue interlayer and an acoustic blanket, together with a clear acrylic diffuser that houses the individually addressable linear fluorescent luminaires. The diffuser, a bespoke linear extrusion designed using Zumtobel's patented waveguide technology, refracts a proportion of the light on to the ceiling and the rest into the interior, free of glare. The fact that the fittings could be controlled independently allowed the light across the space to be exactly balanced.
Extensive mock-ups were used to test the profile and the relationship between the diffused, refracting light source and the reflective surfaces, a process through which the design evolved. Other crucial features such as concealed fixing details, panel accessibility and material finish were also determined at this stage.
The individual ceiling cassettes were based on a 1500 module (actually 1475) and, for ease of construction and replacement, were designed to exactly fit a standard linear fluorescent luminaire.
‘Through its spacious volume, finishes and lighting design, the entrance foyer provides a transformed backdrop to the street promenade and activities centered on City Point Plaza,' commented Brundle.
