Behind the Design

Unique Properties: The lighting design was made for revitalizing a historical shopping environment. The designers have inserted a light installation that creates a very special mood during the day and night. Thanks to the intelligent control system, interaction between architectural ambient lighting and the theatrical feature pendant encourages the perception of a unique rhythm reflective of the West End. When daylight falls, the installation with visible dynamics gains more attentions and attracts visitors.
Dimensions & Packaging: Despite the temporal dynamism of ambient lighting, light levels have been achieved according to British Standards. The sustainability led lighting design approach for Quadrant Arcade targets delivery of an ‘Excellent’ rating against the BREEAM UK Refurbishment and Fit Out 2014 methodology.
Tags: Visual navigation, heritage illumination, dynamic lighting, visual interest
Production Technology: The various lighting elements are divided into groups that can be individually controlled, offering different light scenarios whose performance corresponds to the movement of feature pendants. Emergency lighting has been discretely recessed into the underside of the cornice to limit visibility and meet statutory norms. Terrazzo flooring, inspired by tiles from Pompeii revealed by uneven lighting provides visual drama.
Design Challenge: Listed interiors have been rigorously restored and highlighted with focal illumination, taking care to consider how new lighting would be installed. The challenge was to reveal historical feature details without exposing direct light sources which would visually compete with the listed building. Luminaire mounting and cable run placement are discreet so that contemporary elements and visual clutter are minimized.
Research: The design involves site appraisal, conservation planning, lighting planing application, computer based lighting simulation and on-site mock up to ensure the finished visual appearance is close to initial aspiration. Final lit appearance has increased the spatial usage dramatically especially during nighttime. Street users passing by are tend to stop over to appreciate the public space and bespoke pendant art. With the increased spatial usage, people feel safer navigating the public space nearby. The social and financial benefits gained due to the lighting transformation are far beyond the energy cost.
Inspiration: Quadrant Arcade is a jewel of The Crown Estate on Regent Street. The design focusses on highlighting essential historical architectural features with minimal interventions and luminaire geometries are selected to match iconic historical forms. The art installation was inspired by paraboloid to create a mathematically generated quadrant in three dimensions using linear lights to achieve an overall curve. The cluster of pendants creates a sweep along the whole length of the arcade.
Project Duration: The project started in March 2015 in London and finished in Feb. 2019 in London, and was awarded Lit Lighting Design Awards heritage illumination category winner.
Operation Flow: The ethereal quality of the structure is accentuated at dusk by concealed and carefully aimed light elements. The contrast between warm, ambient lighting and cool, dynamic feature pendants provide a strong focus in supporting the artistic vision. The high output and efficacy of new fittings were key in resolving the challenge to provide sufficient ambient light to the space with the variable intensity of the feature pendant.
