GDC webinar: Experts shed light on smart lighting

We invited experts in the field of smart lighting to our 10 October 2016 webinar.

A recording of the webinar is available on YouTube channel at http://bit.ly/2rqmz7A.

Following a brief summary of the Green Digital Charter (GDC) training activities and agenda, Ingjerd Bratterud, head of project section, parks and street department, city of Stavanger, walked us through the story of how her city came to use LED lighting in public spaces.

The energy company Lyse owns, develops, and operates the public lighting systems in Stavanger and its neighbouring municipalities. It started testing LED lamps in 2008. Currently around 1,300 lighting fixtures are equipped with LED lamps. Between 2016 and 2019, about 6,600 mercury vapour lamps will be replaced with LED lights in Stavanger.

Bratterud gave some hints and tips about what is important to consider when investing in LED fixtures, and she also summed up the functional requirements of such systems. Switching to LED lamps can reduce energy consumption and costs, lower the environmental impact, and enhance the quality of life of citizens. Stavanger is well on its way to becoming a smart city. Bratterud’s presentation was followed by a lively discussion.

Arthur Noordhoek, adviser and project leader lighting, city of Eindhoven, has played an active role in his city’s transition to smart lighting. Eindhoven’s prime aim with the LEDification of its lighting fixtures is to save energy and promote sustainability. The city understands that public lighting contributes to road safety and adds value to society.

In Eindhoven, the installation of LED lamps has resulted in 25% extra energy savings. In 2012, the city developed its 2030 Vision and Roadmap on Urban Lighting. Eindhoven is determined to employ innovative technologies and involve the citizens in addressing socially relevant issues. According to Noordhoek, there is no victory without the end users’ involvement. “Our citizens are the only ones who can judge if the solutions fit or not”, he said.

Neil Platt, special projects manager, street lighting, at Balfour Beatty (contracting partner of Coventry City) presented his city’s private finance initiative (PFI). Coventry completed its core investment programme within five years of its launch. Between year six and year 25, they will be in “maintenance mode”. In Coventry, nearly 100% of the columns, lanterns, and subway and city centre lighting fixtures have been replaced and solar bollards have been installed.

Platt explained the city’s investment methodology and demonstrated that smart lighting can indeed maximise energy savings. Real savings come from full redesign and value engineering, he said. The table below provides further technical details.
