Does smart street lighting control system save energy?
The financial evaluation model developed provides total cost of installation, cost benefit analysis, and the net present value of the smart street lighting control system. The financial evaluation of the model shows that energy saving by implementing smart street lighting control system has a payback period of 4 years and 6 months. The net
How much does smart street lighting cost?
The initial cost for installation of smart street lighting control sys-tem is $, and it is zero for the existing system. The annual energy cost of smart street lighting con-trol system for East Main Street, El Cajon, is $852 and for the existing system is $ (SDGE Elec-tric Serive, ).
Can smart street lighting be economically feasible?
Besides relying on a simple payback method to determine the economic feasibility of smart street lighting, it is also equally important to make a LCC analysis (Steven, ). Based on the Life Cycle Cost analysis, net present value (NPV) and return on investment can be calculated.
How much energy does street lighting use?
about 40% of total energy usage in cities (Ożadowicz & Grela, ). It is estimated by the International Energy Agency (IEA) that the global energy consumption for street lighting is 114 TWh per year (Irsyad & Nepal, ).
How long does a streetlight project take to make a profit?
present value analysis shows that the project can start making profit after 3 years. By , it is predicted that approximately three bil-lion people are expected to live in the cities (Gul, et al., ). Hence, streetlights are very important elements of infrastructure in the cities.
Are Streetlights energy-saving?
This experiment demonstrated that streetlight energy-saving system enhances the activities of lights in a manner that allows them to be dimmed to 50% of the rated power throughout two-thirds (2/3) of the night (8 h) (Todorović & Samardžija, ).
