Street Lights Are the New Smart Phones

— May 11, 2016

BulbsJust as cell phones have evolved into multifunctional digital information devices, the once-humble street light is becoming a hub for monitoring a variety of urban activities and sharing data with networks.

Navigant Research identified this trend in its 2015 Smart Street Management report, stating that, “Smart street lighting is becoming one of the most attractive solutions for cities looking for an immediate effect on energy consumption and operational costs while also laying a foundation for a broader range of applications.”

As street lights are being upgraded to more efficient LEDs, pole owners are seizing the opportunity to add networking capabilities, sensors, cameras, and power management intelligence to leverage the lights’ distributed electrified reach to provide a variety of services across cities. The convergence of city management technologies with street lights was on display throughout the recent Intertraffic conference in Amsterdam.

Intertraffic Conference

Examples highlighted at Intertraffic included Streetline, of San Mateo, California, which is working with Cisco on using cameras fixed to street lights as a less expensive alternative to sensors to predict parking availability. According to Kurt Buechler, Streetline’s senior vice president, the cameras cost around $100 each and are connected to a cloud service that performs analysis on the collected data. Cisco is also working on integrating cameras and Internet of Things technologies to street lights in the Netherlands via its IT networks.

Also at Intertraffic, Spain’s Circontrol announced its Trilogy offering, which combines lighting, smart parking detection, and indicators that show parking availability. Circontrol also displayed an integrated parking facility energy management system that uniquely incorporates electric vehicle (EV) charging management. Intelligent transportation systems vendor Q-Free is combining its air quality monitoring technology with street lights in Medway, England.

EV Influence

Other companies taking advantage of the ubiquitous presence of powered street lights include BMW, which adds EV charging capabilities through its Light and Charge initiative. In the city of San Jose, California, the SmartPoles pilot project is using wireless technology from Ericsson and Philips’ energy efficient lighting equipment to reduce costs while providing more flexible lighting management.

The convergence of smart parking, traffic management, EVs, and environmental monitoring—often using connected street lights to collect and share data—will bring much more holistic views to smart city managers looking to understand the full effect of transportation on urban life. Standards for data collection and communications protocols are quickly evolving to enable this broader view and will be of growing importance as cities look to understand and mitigate the effect of increased congestion and urbanization.

 

Panasonic-Denver Partnership Highlights Cultural Considerations in Smart City Projects

— February 22, 2016

Bangkok SkylineIn January 2016, Japan-based Panasonic and the city of Denver, Colorado announced a partnership to transform the mountain municipality into a smart city, with a focus on improvements to transportation, energy efficiency, water conservation, and public safety, among other services. The focus project of the public-private partnership is the creation of a greenfield community southwest of the Denver International Airport called Peña Station NEXT.

Using Panasonic’s CityNOW approach, the new community in Denver is being modeled on the successful development of the Fujisawa Sustainable Smart Town in Japan. Fujisawa is 31 miles west of Tokyo and as has a comprehensive smart city implementation across multiple applications, including smart street lights and  rooftop solar panels that power homes during the day while fuel cells and batteries are utilized at night. The community is also in walking distance to public transportation, and electric cars and bicycles are widely available for rent.

This is a significant example of how companies like Panasonic are trying to take best practices from smart city projects in Japan to North America and other markets. Other Japanese giants have also been working with North American and European cities on a range of pilots and demonstrator programs, but the Panasonic-Denver collaboration is one of the most significant commercial projects to date.

Cultural Challenges

However, the translation of experiences in Japan to the United States raises some interesting challenges. According to the Denver Post, Denver’s smart city initiatives will have several different applications compared to what took place in Fujisawa, primarily in order to account for cultural and social differences between the two countries. Camera monitors with facial recognition spike much higher privacy concerns in the United States compared to Japan; as a result, the Denver project is expected to be much less intrusive. Instead of shared cars and bicycles, the Peña Station NEXT community is likely to use shuttles with parking garages and parking lots to accommodate some personal vehicle usage. In addition, far-reaching liability concerns in the United States mean that automated street lights are also unlikely, with dimming ability being a more realistic approach. While many of the same essential technologies that were tested in Fujisawa (i.e., cameras, smart street lights) are being applied in Denver, precisely how they are going to be used is being augmented for cultural considerations.

Through the partnership with Panasonic, Denver looks to improve its greenhouse gas emissions per capita, as the city’s sprawling infrastructure all too often encourages driving as the primary means of transportation. According to a 2011 World Bank report, Denver ranks far below other more densely populated cities with 23.7 tons of CO2 emissions per person. It’s a high figure, especially when compared to other locations like New York City (8.7), San Francisco (10.1), and Boston (13.3). The American Community Survey from the U.S. Census Bureau shows that Denver County has some of the highest rates in the country of commuters driving to work from surrounding counties.

While there are several common themes that go into making a city smart (such as digital technology, sustainability, mobility, and financing), how these factors are implemented changes drastically by jurisdiction. Initiatives that helped Japanese cities become smarter are likely to have relevance in other countries such as the United States, but some differences in implementation are needed for project success.

 

New Zealand Street Lighting Updates Could Make for an Attractive Market

— May 5, 2015

New Zealand lighting designer Bryan King estimates that his country is roughly 5 years behind the United States in terms of upgrading street light infrastructure from high-pressure sodium (HPS) to light-emitting diode (LED). Recent developments and a successful Road Lighting conference, however, may help close that gap quickly or even put the small country in the lead. This makes for an interesting case study in how a smaller market can rapidly shift from one technology to another, undergoing the process at a much faster rate than larger markets are capable of doing.

Favorable Factors

According to Navigant Research’s Smart Street Lighting report, there are an estimated 370,000 street lights installed in New Zealand. This represents a small fraction of the installed base of the United States and other large countries, making the challenge of upgrading far less daunting. Another significant factor that this country has in its favor is that municipal lighting is generally owned by the municipality, rather than by a utility that may not have a financial incentive to reduce electricity consumption, especially during nighttime hours. In addition, 50% of funding for street lighting comes from the NZ Transport Agency. This government agency has recently stipulated that its funding must be spent on LED lights and not on older lamp technologies. That alone will spur retrofit projects and likely means that no new HPS luminaires will be purchased.

The recently held Road Lighting 2015 conference is also expected to drive adoption of both LED street lighting and networked street lighting control. The conference organizers were able to gather representatives from a significant portion of the country’s municipalities, who then learned from city managers and other experts from around the world who have already implemented LED and controls projects. While decision makers in the United States often seem reluctant to draw on international experiences, decision makers in New Zealand were quite eager to benefit from the lessons learned by their peers around the globe.

Road Lighting

A significant focus of the Road Lighting conference was on the use of networked controls to deliver advanced control features to street lighting systems. As discussed in Smart Street Lighting, networked systems are being adopted in ever growing numbers around the world, but many municipalities have upgraded to LEDs without also adding controls. A new and widely adopted American National Standards Institute (ANSI) standard (136.41) means that adding controls after a luminaire has been installed is relatively simple, but it still involves physically accessing every single street light. Thus, it entails a cost and effort that deters many municipalities. New Zealand is in an excellent position to take advantage of the benefits of both LEDs and controls, installing both of these now maturing technologies at the same time to reduce costs.

It is yet to be seen just how quickly New Zealand will adopt LED street lighting and networked lighting control. The City of Auckland has announced plans to switch all of its lights to LEDs in the next 5 years, and the timeline is expected to be similar for other cities and only slightly slower for smaller municipalities. So, while the total market size is modest, the rapid changeover when conditions are ripe can still make a small market attractive to international manufacturers.

 

LEDs Lead Smart City Networks

— July 3, 2014

The path to more systematic and dynamic control of street lighting is being blazed by the adoption of light-emitting diode (LED) technology.  The continuing fall in the price of LED street lights has made them attractive to city managers around the world, particularly for new installations.  In our new report, Smart Street Lighting, Navigant Research estimates that 53% of street light luminaire sales in 2014 will be LED, and that percentage will grow to 94% by 2023.

This rapid transition to LED street lights is occurring as new, networked control systems become widely available.  These systems can bring added energy savings as well as additional value through greater control and reduced maintenance costs (see here, here, and here for examples).  Given the comparative ease and reduced cost of installing a control node while replacing a luminaire, the LED transition is proving to be a boon in the adoption of networked street light systems.  Navigant Research forecasts that revenue from the control equipment for such systems will grow from $197 million in 2014 to $477 million by 2023.

Illuminated Backbone

With the installation of a network that can communicate with street lights comes the opportunity to integrate those controls with multiple other intelligent systems: traffic light controls, security cameras, electric vehicle charging stations, environmental sensors, and digital signage.  The availability of both power and communications on street light poles throughout a city provides a ready-made backbone for many of those other services.  The same communications infrastructure can often be expanded for additional applications, and once the value of one such system is proven, city managers become far more likely to seek new applications for the technology.

In order to fulfill the potential of integration between multiple smart city systems, however, smart street lighting systems have to become more adaptable and more open.  In short, they need to look more like platforms than proprietary, closed systems.

Standards Emerge

The adoption of standards at multiple levels is crucial if smart street lighting networks are to serve as the platform for other smart city projects.  Standards adoption will open up the market and provide cities with more choice and greater confidence about the future value of their investment.

Standards-based software and communications protocols enable greater interoperability between systems, but there is also a role for more standards at the hardware level.   For this reason, the publication of a new standard by the National Electrical Manufacturers Association (NEMA) earlier this year is an important development.  Standard 136.41 defines a dimming controller and socket for street light luminaires.  The implication of the new standard is that, as long as a city purchases compliant street lights, it will be able to add control features, such as dimming and wireless communications, at a later date simply by purchasing any vendor’s compliant controller and plugging it into the top of their lights.  I discussed the new standard in more detail in a previous blog.

For a detailed examination of the benefits of smart street lighting for smart cities, the challenges still to be addressed, and Navigant Research’s forecasts for the growth of the market, please join us for the upcoming free webinar, Smart Street Lighting for Smart Cities, on July 8 at 2 p.m. EDT.  Click here to register.
