A major visual landmark, which also brings sustainability and social and economic benefits, has been unveiled on The Francis Case Memorial Bridge at the Hoffman-Madison Waterfront development in Washington DC. It has been designed by Citelum, a subsidiary of the energy company EDF, which specialises in implementing solutions for smart lighting and connected services.

 

The objectives of the design-build project at The Wharf, inaugurated by Washington DC’s Mayor Muriel Bowser, were to create a visual experience that supports the renewed activity of the area while blending into Washington DC’s nightscape.

 

The final design creates a vibrant visual experience for night-time visitors and residents and is expected to boost The Wharf’s night-time activity, setting a precedent in DC’s illumination. The new design will evolve over the hours, from sunset to sunrise, transitioning from warmer to colder white light, before going back again until the morning hours.

 

The initial concept was presented to Hoffman-Madison Waterfront in Spring 2014 and was approved by the Department of Transportation and the Commission of Fine Arts in April 2015. Over 20 fixture combinations were analysed and more than 400 energy-efficient LED lights were installed in order to create the vertical wash that highlights the texture and craftsmanship of the piers’ stonework, and the blue LED line that marks the silhouette of the structure.

 

Citelum’s previous lighting projects include London Tower Bridge, the Eiffel Tower and Mexico City’s Monumento a la Revolucion. Citelum believes the Case Bridge is another illustration of the benefits that lighting can bring to cities not only in terms of attractiveness, but also in terms of social and economic development and sustainability.

 

Headquartered in Paris, Citelum has 20 years’ experience combining international best practices and innovative technologies. It designs, upgrades, finances and maintains lighting infrastructure that supports city optimisation and helps guide authorities in their transition to becoming smart cities.
