Asunción Santamaría UPM DAY 2: SMART CITIES TABLE 4: IMPLEMENTATION OF THE SMART CITY CONCEPT INTERNATIONAL SUMMER SCHOOL “SMART GRIDS AND SMART CITIES” Barcelona, 6-8 June 2017
WHY? • To improve visibility • To extend the day • To enhance commerce and “urban” activities (leisure). • To feel safer • Primal fear of the dark HOW to improve lighting? • Minimizing glare/blinding • Use white light allows lower illumination levels • Illumination level reduction can be done keeping the same target visibility: https://youtu.be/VrqOWTPX7eQ • Contrast matters (more that uniformity or lighting level) • Use warm Correlated Color Temperature (CCT): http://www.lrc.rpi.edu/programs/nlpip/lightinganswers/lightsources/whatisCCT.asp http://volt.org/smart-lighting/ 2
Traditional outdoor lighting systems Old technologies: Incandescent bulb, Halogen lamps, • Compact Fluorescent Lamps (CFL), High Pressure Sodium (HPS) • Inefficient electrical to optical conversion • Light pollution Lamp type Relative Consumption (%) Incandescent Bulb 100 Halogen Bulb 70 Fluorescent Bulb 30 HPS 30

CeDInt Smart LED based System BatStreetLighting (BSL). Main features. • LED based lamps Automatic and manual remote working modes • Smart behavior algorithm • • Luminosity sensor • Motion/presence sensor • Intercommunication among streetlights
BatStreetLighting (BSL). Network behavior.
BatStreetLighting (BSL). Algorithm behavior.
BatStreetLighting (BSL). Management system.
BatStreetLighting (BSL). Results. 56% Energy consumption savings by technology migration (HPS to SSL) • • Up to 68,8% extra savings due to the BatStreetLighting solution (depending on pedestrian transit). • 85% of total savings. http://www.cedint.upm.es/en/project/batnet http://www.cedint.upm.es/en/infrastructure/internet-things-lab https://www.youtube.com/watch?v=Joj7gb7tjZM https://www.youtube.com/watch?v=Fzi6BU35848 https://www.youtube.com/watch?v=2ErNQRbwFjc
15 Hard-To-Find IoT Skills http://www.ioti.com/iot-trends-and-analysis/15-hard-find-iot-skills ON-GOING experiences The SOLA Community Friendly Lighting Certification: http://volt.org/community-friendly-lighting/ PREDICTIONS....... Streetlights are the backbone of IoT (neutral platforms that provide the tools of connectivity to everyone). https://backchannel.com/the-surprising-backbone-of-the-internet-of-things- 4330301084b0 Sensors attached to street lights and other outside urban furniture will measure footfall, noise levels and air pollution and this data will be used to prioritize delivery of other services. https://www.forbes.com/sites/bernardmarr/2015/05/19/how-big-data-and-the-internet- of-things-create-smarter-cities/#d7ef56817677 The reason for 5G to be there is to actually to finance the whole thing http://www.ledsmagazine.com/articles/2017/06/the-funding-of-urban-smart-lighting- could-hinge-on-5g.html 11
