ISSUE STATEMENT: The City of Springfield's street light system has continually declined over the last decade to the point where traffic maintenance staff has worked with Springfield Utility Board to replace legacy street light technologies with LED fixtures. The street light system is essential and relied upon by the community to illuminate transportation systems in residential, commercial, and industrial areas. We estimate approximately 30% of the system has transitioned to LED organically as failures occur. In addition, there have been substantial improvements in LED technology over the last decade along with decreasing cost. LED fixtures use substantially less energy than legacy fixtures and require less frequent maintenance. As a result, the City can save money by proactively replacing all legacy street light fixtures with LED. The sooner this project is executed, the sooner this savings can be realized and the more money the city will save. The following presentation is a proposal to conduct a proactive full system replacement instead of reactively replacing fixtures as thev fail. ATTACHMENTS: Attachment 1: Street Lighting Program Update Council Briefing Memo Attachment 2: Street Lighting Program Update Presentation Attachment 3: McKinstry Proposal DISCUSSION/ FINANCIAL City Staff intends to conduct a proactive city-wide replacement of legacy fixtures IMPACT: with LED fixtures, instead of reactively replacing fixtures as they fail. Within approximately one year, this project will replace all non -LED street light fixtures with LED fixtures, which will improve the quality of our lighting system along with substantially reducing operating, maintenance, and energy costs. This project will pay for itself through savings over approximately 10-12 years. Staff evaluated the services ESCO can provide and determined that using an ESCO is the best combination of service, expertise, schedule performance, and cost. An RFP/Q may be required to access ESCO services however if a cooperative procurement contract, also known as a piggyback contract, is available a time consuming and costly Request for Proposal/Qualifications process is avoided and allows the City to immediately enter a services contract.

The following presentation is a plan to conduct a proactive full system replacement instead of reactively replacing fixtures as they fail. 10X"►[] 1 r Lero7:,I IIMA MANDATE: Maintain and Improve Infrastructure and Facilities BACKGROUND: Current System Information and Operational Challenges • The City owns 4,557 street lights. 3,214 (-70%) are High Intensity Discharge (HID) lights, consisting of Low Pressure Sodium (LPS), High Pressure Sodium (HPS), and Metal Halide (MH) fixtures. 1,433 (-30%) are already LED, which can be attributed to new construction, specific upgrade projects such as Downtown Lighting improvements, and LPS lifecycle replacement. • Springfield Utility Board (SUB) maintains this city -owned system. • HPS and MH bulbs have a 4-5 year lifespan and require frequent maintenance to replace bulbs and ballasts. • LPS replacement parts (i.e. bulbs) have become boutique products and are no longer manufactured in commodity sized quantities and are costly to purchase. As such, when LPS fixtures fail, they must be replaced entirely. This has caused ongoing maintenance costs to increase significantly in the last few years. The City has chosen to replace these with LED fixtures, so that the repair cost can also contribute towards upgrading the light. The City has already replaced over 1,100 LPS fixtures in this manner. • Increasing Operations & Maintenance costs and increasing energy costs mean that this aging system becomes more expensive to maintain and operate with each coming year. • We often rely upon citizens to report outages, leading to relatively long repair times. Attachment 1, Page 1 of 2 Value of upgrading to LED • LED lights use approximately 50% less energy and need approximately 75% less maintenance. • Improved lighting levels will contribute to improved level and quality of light, which will contribute to better traffic and pedestrian safety. Current light levels often do not meet adopted city standards. (Crash Reduction Factor of 16-74% depending on treatment.) • LED fixtures have an average lifespan of 20 years. • The City will save approximately $180,000 per year in energy and maintenance costs (in today's dollars). Due to inflation and rising energy prices, this savings will continue to increase over time. • Project pays for itself through lower utility bills—payback period of 10-12 years. • The cost of LED fixtures continues to decrease, and the efficiency of LED fixtures continues to increase, with substantial improvements made in the last few years. New fixtures are approximately 20% more efficient than just 1 year ago. A wider range of colors is now available. In the past, 4,000 Kelvin was the lowest color temperature available, but now 3,000 Kelvin is available. This temperature comes with a slight loss of efficiency, but some people find this color to be more pleasing to the eye. Recent research indicates that the best human visual response to activity in the street or sidewalk, at street light illumination levels, occurs at 4,000 Kelvin color temperature. As a result, staff plans to use 4,000 Kelvin in all situations. • We can incorporate smart lighting controls with a remote -control system. This system will allow City staff to remotely control, monitor, meter, dim, trim, and automatically report outages to maintenance personnel. This will reduce repair times and will allow further energy savings if the City Council adopts a dimming and trimming strategy. This will also allow us to address citizen complaints more readily. Options City staff has researched the following replacement approaches: 1. Continue replacement as failures occur; service may be interrupted for up to several months, higher replacement cost, inconsistent lighting types throughout the city, creates drain on street fund Operations Division budget. 2. Conventional design, bid, and build project using either city staff or a consultant to manage and engineer the project over approximately three years; project could be funded by debt financing that is repaid through annual energy and maintenance savings. 3. Partner with an Energy Service Company (ESCO) to deliver the project over approximately 1 year; project could be funded by debt financing that is repaid through annual energy and maintenance savings. RECOMMENDED ACTION: Staff recommends Option 3, Partner with an Energy Service Company (ESCO). This approach is superior in every way compared to Option 1 (timeline, cost, quality). Compared to Option 2, this approach will more efficiently deliver a higher -quality product at a competitive price.

Lighting should only be on when needed. 2. Lighting should only light the area that needs light 3. Lighting should be no brighter than necessary for the intended use. 4. Minimize blue light emissions 5. Lighting should be fully shielded (pointing downward) The color of light is important. Both LED and metal hatide lamps contain large amounts of blue light in their spectrum. Because blue light brightens the night sky more than any other color of light, it is important to minimize the amount emitted. Some studies have shown that exposure to blue light at night can be harmful to human health and endanger wildlife. Using lighting that has a color temperature of no more than 3000 Kelvins is therefore recommended. The graphic below shows the Kelvin rating for various lamp types. 0 Kalvin -Mmparatura Chart The illustration to the left provides a visual guide to the differences that the design of the light fixture itself has on light pollution (and desires to become dark sky compliant). Fixtures clouded in red show representative sample of fixtures similar to what PAR currently has installed that are considered unacceptable or discouraged due to light pollution concerns. The green clouded examples show similar fixtures that are considered acceptable for light pollution concerns. 1. Based on the pathway lighting found at the sites included in the ESPC scope of work, the primary fixture types being used are Lantern or Shoebox with a few decorative Acorn style fixtures at Ed Benedict Memory Garden. 2. Acceptable Lantern fixtures should be fully shielded. This means the lamp should he in a horizontal orientation within the top shield of the fixture. 3. Acceptable Shoebox fixtures should be fully shielded. This means the lamp should be in a horizontal orientation within the top shield of the fixture. 4. Acceptable Acorn fixtures should be fully shielded. This means the lamp should be in a horizontal orientation within the top shield of the fixture. SUMMARY: Converting the existing pathway lighting to 3,000 kelvin LED technology will reduce the energy consumption of the existing lighting by 40-60% but will not drive reductions in light pollution. The new LED fixture wattage should he selected to provide the minimum amount of light required, Installation of new fixtures will have a longer payback but will reduce the light pollution. lll��naaw can c�emszoos. wma�.e rix ln.e„r,.rsa,.,r�. hv.v�e,,,etoa.nl. In addition to the conversion to LED lighting a control system would allow the light level to be dimmed, further reducing the energy consumption but improving on the light pollution impacts as well.
