Combined with LED lighting, CityTouch can save cities up to 70% in energy and 70% in maintenance costs. The system makes use of an online interface for lighting operators that provides real-time status reports for every light point in the city. CityTouch is currently being tested in several European cities, including Prague and London. The system looks very promising, so it would be great to see it being rolled out in more cities in the future. Click here to watch a video which explains the concept. In case you’re inspired, you should definitely also check out CityTouch’s little brother Dial4Light, a text message-based urban lighting system we discussed earlier on Pop-Up City.
