EXTERIOR LIGHTING | LONDON WALL PLACE Left: Concealed lighting has a mix of colour temperatures depending on materials and planting We wanted to understand how little light we could use that would still allow people to navigate safely, but get a sense of solitude and tranquillity an iridescent coating of concrete and faience that reinterprets the knapped int of the sites Roman and Saxon remains. StudioFractal was given a varied remit: an acre of public space that included landscaped gardens, historic ruins, commercial and retail facilities, and multilevel pedestrian routes. The detailed lighting strategy, knitting together commercial lobbies, gardens and the reimagined High Walk linking to the Barbican, was designed to enable views through the project, ensuring veiling reections in glazing were avoided so interior and exterior spaces were connected. The layered scheme combines direct and reected lighting. It creates a softly undulating visual environment, making use of light, shadow, reection and projection to complement and enhance the material palette of stone, metal, water and planting, and to encourage exploration, says Downey. A hierarchy of concealed light sources was developed and located within architectural detailing, with a mix of colour temperatures according to the materials and planting. The aim was to draw the eye between historic and contemporary forms and materials, and invest the gardens with a serene, contemplative feeling. We were interested in creating a night garden, and wanted to understand how little light we could use that would still allow people to appreciate the gardens and navigate safely, but, nevertheless, get a sense of the tranquillity and solitude, Cladding with an iridescent coating of concrete and faience unites the development The High Walk linking to the Barbican enables views through the project www.cibsejournal.com December 2019 5 CIBSE Dec19 pp04-06 Exterior lighting Supp.indd 5 22/11/2019 14:50
