LED Scale-up

LED Scale-up

led header

We're working to transform how we light our world. Lighting accounts for nearly 6% of global CO2 greenhouse gas emissions, or 1,900 million tons of CO2 per year— the equivalent of CO2 emissions from 70% of the world’s passenger vehicles. By making lighting more energy efficient we can make a significant dent in carbon emissions.

Light-Emitting Diode (LED) lamps can cut CO2 emissions by 50–70%, with additional savings achievable with flexible smart controls. LED outdoor lighting also reduces costs, enhances public safety, minimizes light pollution and makes public spaces friendlier at night. The potential for LED technology is unprecedented: some industry experts predict that within 10 years LED lights, both indoor and outdoor, could deliver more environmental and economic benefits than any other clean technology including renewable power.

Acknowledging the potential for energy efficient LED lighting, in 2012 we conducted the ‘Light Savers’ project - a global trial of LED lamps in 12 large cities around the globe to evaluate how the latest LED products performed and how they were perceived by the public.

The results of the LightSavers project presented in the ‘Lighting the Clean Revolution’ report highlighted how the LED technology was mature and ready for full scale roll out around the world. Along with the core report, The Climate Group also published a technical summary for lighting managers as well as a series of city specific reports.

Following the Lightsaver findings in 2012 The Climate Group called for all new street lighting to be LED (or as efficient) by 2015, and all street lighting to be LEDs (or as efficient) by 2020.


Since then, a number of cities have announced major upgrades to LED, however it has become clear that the vast majority have still yet to make the move. As a result in, 2014 we entered the second phase of the LED-scale up project and announced the launch of a consultation process supported by our lead Partner Philips Lighting, with the aim of identifying the remaining regional barriers to adoption of LEDs and accelerate the transition to energy efficient lighting around the world.

One year into the consultation process we have organized a series of events and workshops around the world convening key regional stakeholders and municipalities to discuss important topics crucial for LEDs scale up in each of the visited region.

A common identified challenge for cities was a need for independent support to city staff as they seek to assess the different business case options for their unique city circumstances, from both the technical and financial standpoints. Such capacity support in the early stages of business case review could significantly help reduce the number of technical and funding options during the tendering process and similarly help to reduce the overall procurement timeframe.

As a result of these and other region-specific challenges we have decided to extend the consultation workshops into 2015-2016.

Case studies

Pilots of LED outdoor luminaires and smart controls are being conducting worldwide by a wide variety of users and manufacturers. Independent studies that follow a rigorous performance methodology are scarce, however. Our LED program is systematically evaluating the best pilot examples available globally and will post summaries and relevant links in this space soon. In the meantime, authoritative sources of case studies and evaluations include:

  • Solid State Gateway Demonstrations (US DOE)
    Detailed reports and briefs on completed projects that focus mostly on intensively studied street lighting and parking area pilots in the US.
  • CALiPER (US DOE)
    Detailed reports on laboratory evaluation of LED indoor and outdoor lighting products in nine rounds to date.

Tools

LED outdoor luminaires have many advantages over conventional high pressure sodium (HPS), metal halide, and fluorescent lamps. LED chip efficiency has surpassed that of these lamps and keeps improving. LED luminaires direct more light on surfaces where it is most needed. Meanwhile, the marriage of smart controls and LEDs makes dimming easy, so energy isn't wasted at times when lighting is not really needed.
