Best Practice Action 4.2

GreenStep City Best Practices: Buildings and Lighting
Efficient Outdoor Lighting and Signals No. 4

Improve the efficiency and quality of street lighting, traffic signals and outdoor public lighting.

Best Practice Action 2

Purchase LEDs for all future street lighting and traffic signals.

  • Street lighting technology is evolving rapidly and is tracked by the U.S. DOE's Municipal Solid-State Street Lighting Consortium which offers a variety of resources, such as performance calculators and model specifications, to guide municipalities and others in their evaluation and choice of LED street lighting products, which importantly includes the choice of color temperature (3000 or fewer degrees Kelvin generally preferred) and color rendition. See MN Dept. of Transportation LED specifications.
  • LED outdoor lighting: barriers and solutions free-to-view webinar recorded in Jan 2017 features a U.S. DOE Policy Advisor discussing municipality-focused LED outdoor lighting conversion best practices and strategies based on real-world examples. [Applicable to 2 and 3 Star implementation.]
  • The comprehensive listing of LED streetlight resources by CERTs covers paybacks, bulb longevity, light trespass, maintenance cost savings, total cost-savings calculators, research in Minnesota, 'how-to' manuals, specifications and more. Also see the CERTs page on LED traffic signals
  • 6-minute video on research and a test of LED street lights with a focus group from three different vendors, run by Dakota Electric Association and the City of Apple Valley.
1 star Have a purchasing practice/policy/utility franchise agreement that specifies EnergyStar traffic signals.
2 star Have a purchasing practice/policy/utility franchise agreement that specifies Dark-Sky street lighting. Streetlights should provide at least 75 lumens/watt (as do LEDs).
3 star Document a purchasing policy/utility franchise agreement that requires LEDs for all new street lighting and traffic signals.

Richfield - 3 star
Date action report first entered:
Date of last report update:
Year action initially completed:
Implementation details:
Street lighting is currently high pressure sodium but it is common practice to replace bad ballasts with LEDs. Xcel Energy doesn't meter it; instead, the City pays a per fixture fee. The City partnered with students from the U of M to conduct an energy audit of its streetlight system. The study recommended LED lights and the installation of solar panels on the streetlights to further reduce energy usage, energy costs and carbon emissions.
Outcome measures/metrics/money saved:
272 LED street lights have been installed in the City, almost 11% of total street lighting.

Year action initially completed:
Implementation details:
The City owns the ornamental street light systems along Silver Lake Road and Old Highway 8. For some of the lights that are unmetered, the City has a maintenance contract with Xcel Energy to service the electrical portion of the lighting system. However, for the lights that are metered the City is responsible for re-lamping, inspection, and maintenance.

The City owns and maintains two street light systems - 95 street lights on Silver Lake Road North and 58 street lights on 5th Avenue NW from 1st Street NW to Old Highway 8. They were originally installed on Silver Lake Road in two phases – 2001 and 2004. The street lights on 5th Avenue NW were installed in 1999. These lights were completely re-lamped in 2008.

The City also owns 30 street lights on Norwest Parkway (NWQ) installed in 2007 and 44 street lights north of I694 along Old Highway 8 installed in 2008, and several lights by Pulte in 2015. The 2007 street lights were due for their first re-lamping in 2015.

All of these lights contain high pressure sodium (HPS) lamps that have an average operating life of 24,000 service hours. On average, 50 percent of the street lights will be burned out or cycling after 6.5 years of operation. During the 2015 Street Rehabilitation project 35 existing luminaires on 10th Street were retrofitted with LED fixtures and 11 new LED lights were installed. To provide for a longer service life, all of the decorative luminaires in the City will eventually be replaced with LED fixtures.

2016 Re-lamp 49 Old Highway 8 Lights north of 5th Avenue
2016 Re-lamp 67 Silver Lake Road Lights south of 694
2018 Re-lamp 58 5th Avenue NW Lights south of Old 8 to 1st Street
2020 Re-lamp 102 Lights North of 694 in the Exchange
Outcome measures/metrics/money saved:
The ornamental lights are a large investment, and need to be maintained and kept in good working order. LED lights are efficient and will significantly outlast the HPS lamps. LED lights installed on metered systems will have their energy use compared to previous years utility data.
