Background:

Philips client, the Public Works and Water Management (RWS) for the Amsterdam Road District  leads by example as far as sustainable infrastructure solutions are concerned. For instance, RWS, in conjunction with other government bodies and knowledge institutions, is using the ‘Sustainable Public Works and Water Management’ program to find the most (cost-)effective way to save energy and reduce the amount of CO2 and other greenhouse gases. In the areas of dredging, earth-moving, asphalt, concrete, purchasing ships and… public lighting.

The Challenge:

60% of energy consumption on highways and waterways goes toward lighting.  When it comes to highways it is difficult to install LED lighting because of the as Willem Zandvliet, Technical Manager of ‘Sustainable Public Works and Water Management’ explains, “The speed of traffic and the large distances between masts necessitate a light level that cannot be achieved by replacing conventional luminaires by LED luminaires on a one-for-one basis.”  However, he continues, “Sustainability is important for RWS, so we’ve decided to start a pilot project. A unique pilot project, because if it’s successful it will mean that the Netherlands will have the first highway in the world with LED lighting.”

“I hope and expect that this project will make us a shining example for both national and international organizations that, like the Deparment of Public Works and Water Management, give high priority to Sustainability.”

The Solution:

A perfect piece of highway was found for the project between Burgerveen and Kaagbrug. The road is only 8 kilometers long and relatively narrow.   In addition, at 12 meters the masts are considerably smaller than normal.” Following extensive market research by Toine Adams, who as senior advisor at Spectrum Advies & Design and is responsible for the lighting plan, only one suitable solution remained in the end: Speedstar from Philips.

“The luminaire has uniform light distribution and excellent color recognition and complies with the most stringent requirements and guidelines. Certainly in combination with Philips’ Starsense telemanagement system, Speedstar offers easily the biggest advantages.”

“The project yields a saving of 180,000 kWh, the annual consumption of some 50 households.”

Benefits:

Ben Groot, property expert at the North Holland Secretariat of the Department of Public Works and Water Management explains the benefits of the Phillips’ system: “Thanks to the tremendous dimming options you can reduce the light intensity from 100% during rush hour to a level of 20% during the hours following it. “That yields a saving of 180,000 kWh, the annual consumption of some 50 households.” Adams has this to say: “The flexible dimming system vastly increases safety for road users. When it’s raining or if there’s been an accident, the light intensity is immediately adapted accordingly. LED lighting also requires little maintenance. Today’s LED light sources hardly ever need replacing. Which spares road users a good deal of traffic nuisance and possible frustration.” Zandvliet concludes: “Following an initial evaluation we will have to see whether we will also deploy LED lighting on other high expressways. “I hope and expect that this project will make us a shining example for organizations that, like ‘Sustainable Public Works and Water Management’, give high priority to sustainability.”
