In Denmark alone there are around 1.000.000 lighting points, of which only 20-30% are LED-based, and out of those fewer still carry sensors. The potential for applying energysaving measures are therefore great, and even with costly upfront investment costs for intelligent lighting solutions, with the right approach it could make a good business case for cities.
Representatives from municipalities, companies and universities recently met at DOLL Living Lab, to discuss the latest development in intelligent streetlighting, and how it could make a good business case for cities, when considering investing in new lighting technology. The event, themed around intelligent streetlighting, with Lighting Metropolis as the lead organiser*, presented the latest updates on research, products and solutions for streetlighting and provided a market forum for producers to showcase their latest innovations to potential buyers from municipalities.
Motion sensors – to name only one Smart City application for streetlighting – can help save energy by up to 80 percent**, by regulating the light intensity through the dimming of lights when there’s no one around, during off peak hours. Also, all motion sensors reduce the maintenance cost because the light doesn’t always burn at a high intensity. They also make the producer’s need to oversize initial light output, to maintain minimum target illumination levels over time, redundant.
-All this, in effect, could potentially pay for the added upfront investment cost of the intelligent light managements, says Teddy Sibbern Larsen, project manager at DOLL Living Lab. He adds that the business case around this thinking is currently being worked on by some of the partners, and a lot of cities will be paying attention to when shared.
Bornholm was presented as the latest case study for motion sensor based streetlighting, with Flemming Bech, project manager at the regional municipality of Bornholm explaining that the investment in the new technology and solution meant an expected energysaving of up to 70%, and 1MDKK in operating cost. Seneco provided the solution and was pleased with their approach to the investment:
-Bornholm chose an open source system, which allowed them to take more of an ownership of the process, and, ultimately, will benefit the municipality, comments Kurt Byskov, CEO, Seneco.
The themed seminar day was the first of several, within the Lighting Metropolis initiative, to inspire cities across Greater Copenhagen to switch to greener public lighting, of high quality. You can read more about the initiative here.
