18 LIGHTING MAGAZINE | August/September 2015 August/September 2015 | LIGHTING MAGAZINE 19 Façade lighting defines our view of cities across the world. The panorama of Paris at night with the illuminated framework of the Eiffel Tower; the view of Sydney Harbour with the light silhouette of opera house and Harbour Bridge; the night view of Rome with the backlit arches of the Colosseum. Cities and communities encourage the illumination of architectural landmarks in order to stand out as a tourist, living and business location. Cultural institutions, companies and private property owners use lighting design for façades in the same manner to model architecture and its materials. Façade lighting punctuates the mastery demonstrated by historic architecture, but also the structural approach of modern architects. Illuminated façades provide orientation in the city, attract attention and enliven public space. Be it as a minimalist or emphatically narrative lighting solution that pushes the boundaries: thanks to new luminaire shapes and individual control, the change to LED technology enables unconventional lighting concepts with the broadest possible scope for design and at times, surprisingly, the connected load of a simple household hairdryer. The challenge is to use light creatively in an ecologically and economically responsible manner and to establish a relationship with its surroundings. BY BENJAMIN HEINE, LIGHTING DESIGNER AND EDITOR AT ERCO What makes good façade lighting? FEATURE We will answer the six most frequently asked questions about façade lighting that designers and clients face at the start of a project. WHAT IS THE CONTEXT IN WHICH THE BUILDING IS SET? The architecture decides on the lighting technology, its surroundings determine the tonality of the lighting concept. A chalet in the vineyards, modelled in a natural setting by moonlight, impresses with just a few selectively placed light sources. The factory building, shrouded in a haze of city lights, catches the eye with directed light from in-ground luminaires emphasising the texture of the old brick façade. The company headquarters in the central business district, on the other hand, sets itself apart from the direct light of display windows in its vicinity with soft light. The effect is achieved with the diffuse reflecting light of walls and ceilings inside. Façade lighting can integrate harmoniously with its surroundings, but also – without standing in competition – set a contrast. What is important is visual balance in the landscape for the reason that illumination which is brighter than that of adjacent buildings, especially with similar lighting concepts, may disturb the neighbour or provoke more intense illumination on their part. The light from the building and that of the city are sufficient to use reflections and brightness progressions to achieve a dynamic façade that makes the Guggenheim Museum in Bilbao a landmark even at night.
