This paper is ideal for civic planners and lighting designers, policy makers, and anyone who is developing business cases for Smart Lighting projects. The authors have used a real-world street lighting environment of 3,768 street lights as the basis for many of their assumptions, and assess the benefits of both an LED retrofit as well as the introduction of advanced smart lighting controls. This approach provides an excellent comparison between the opportunities for savings between LED retrofit and Smart Lighting projects.
This study includes assessments based on:
The study does not include the Operations & Management savings from advanced Smart Lighting solutions. Other studies have shown the O&M costs of street lighting estimated at 85% of the total cost of ownership of street lighting with only 15% in capital costs (‘Energy efficient street lighting’, European PPP Expertise Centre, European Investment Bank (EIB), Luxembourg, 2013).
Using the authors’ estimate of GHG emissions saved, equal to 10% of electricity savings, we can estimate the contribution of advanced lighting control and effective lighting as 3.5% additional to the 14% GHG savings from advanced lighting control and 8% GHG savings from effectively designed lighting scenarios to estimate the potential GHG emissions benefit of Smart Lighting solutions at 25.5% of current GHG levels.
For clarity, the authors define advanced lighting control as:
“In the simplest case, it relies on scheduling, where luminous fluxes change according to the predefined rules at fixed hours and do not depend on actual environment conditions such as traffic flow intensity, ambient light level or weather conditions. In the advanced scenarios, a lighting installation performance is adjusted dynamically on the basis of environment state’s changes reported by a telemetry layer (induction loops, weather and occupancy sensors, etc.).”
The authors also define effective design, or optimization of the installation as:
“The scope of this [optimization] process may vary depending on a particular case, from appropriate lamp dimming and changing the fixture mounting angles or arm lengths to displacement of selected poles.”
In the article, “The Business Case for Smart Lighting as the Smart City Network“, we apply the authors’ excellent work, along with other sources, and apply it to a real-world city roadway, energy, CO2 equivalents, and lighting inventory data model. In this model, we find that the diversity of roadway classifications, city size, and mixture of lighting assets has a significant influence on potential cost savings:

“A report has been received regarding the theft of electrical infrastructure at a railway station in the southern part of the country. Two trenches were discovered from which communication cables buried in the ground were removed, totaling approximately 300 meters. This caused significant damage and has disrupted the signaling and traffic management systems of the railway in the southern region.”
