Intelligent Street Lighting Saves 80 Percent on Energy

Delft University of Technology (TU Delft) alumnus Management of Technology, Chintan Shah has developed an intelligent street lighting system that could save up to 80% on energy.

Shah won a competition in 2010 with his concept of LED lighting, motion sensors and wireless communication that allows a street light to dim to 20% of its overall power when there are no cars, cyclists or pedestrians nearby.

Delft University is running a pilot of this design on its campus.

In the Netherlands, where Delft University resides, more than 300 Euros a year is spent on electricity for street lighting. The whole network of street lighting emits over 1.6 million tonnes of CO2 a year. Being able to bring the lights to 20% power when no one is around will significantly drop both of these figures, saving money and the environment in one fell swoop.

The number of solutions that this sort of lighting design solves is much more than first glance. Money and CO2 are saved; light pollution drops significantly, and the cost and time it takes for maintenance to be carried out drops as well, with an intelligent wireless solution that notifies the control board when a light fails.

All in all, I look forward to playing with these lights when they finally make their way out to Australia. I just hope I’m not arthritic before it happens.
