One of America’s largest municipalities, the city of Cincinnati is steeped in tradition and history dating back to the 1790s. The city is home to some of the most unique architecture in the country, and preservation has long been a Cincinnati hallmark. In recent years, Cincinnati has turned to using modern technology to improve the overall community.
A community-wide green initiative was endorsed by the city council and a comprehensive contract was awarded to Honeywell Energy Services to design and implement energy savings projects among city-owned properties. Outdoor lighting, especially street lighting, was quickly identified as a significant opportunity to save energy, and with it came the potential to reduce city maintenance expenses. Beyond that, improved lighting quality also carried strong safety implications for the community.
Honeywell partnered with Eco Engineering to audit, design, and implement the outdoor lighting system. We retrofitted nearly 50 different types of outdoor lamps, using only 12, standardized LED technologies. This project included developing customized street lamps and components to fit historical, antique, and decorative fixtures throughout the city. The lighting project spanned parks, recreation centers, and overpass/underpass lighting. This aspect presented a notable challenge given that many of the spaces that needed new lighting systems were “always on,” and implementations needed to cater to that environment.
The LED solution deployed lamps rated for over 100,000 hours of use, with 10-year warranties that guaranteed enhanced brightness and more consistent performance from street lights over a longer period of time. The resulting maintenance savings were significant.
This project for the City of Cincinnati resulted in impressive energy savings that equated to removing 4.8 million pounds of carbon dioxide emissions from the atmosphere.
- Forecasted Annual Demand Reductions: > 9,017 kW in the first year.
- Annual Consumption Savings: 3,126,204 kWh
The new lighting system offered substantial financial benefits for the city, resulting in hundreds of thousands saved annually
- Forecasted $13,000 energy saved per month
- $4,000 maintenance expenses saved per month
- Total annual energy savings >$204,000

Cincinnati is one of America’s largest municipalities, and it is steeped in tradition and history dating back to the 1790s. The city center in Cincinnati is showcased by the Tyler Davidson fountain, a bronze statue gifted to the people of Cincinnati in 1881. The fountain and its surrounding square remain a central gathering place for the community. Recently preservation using modern technology has become a new municipal standard for the area.
When the city council endorsed a community-wide green initiative, the city began to evaluate ways they could improve their energy savings throughout all city-owned properties. Outdoor lighting, especially at Fountain Square, was quickly identified as a source where the city could both save energy and reduce city maintenance expenses. The fountain in Fountain Square utilized more than 65 high-wattage, incandescent flood lights. Aside from the energy drain of these lights, they output a tremendous amount of heat. As a result, the water from the fountain was needed to cool the fixtures. This meant that the display was inoperable during the winter months when the water was drained from the fountain to prevent damage from freezing. Moreover, since the floodlights were located beneath the water, they were prone to fixture corrosion, leaking, and electrical mishaps. Fountain Square needed a robust, long-term lighting solution that was not only energy efficient, but also maintained or improved the aesthetics of the surrounding area.
When the Cincinnati city council enlisted Eco Energy for this project, we quickly recognized that energy efficiency and aesthetics were not mutually exclusive. We replaced all existing lights with 90w LED color-changing floods with the ability to direct light – using fewer fixtures and less energy. Beyond that, we were able to address both their energy and aesthetic requirements with a single lighting system.
We enabled sixteen pre-programmed shows through the LED displays, changing colors for different seasons, holidays, and events. The LED solution deployed lamps rated for over 50,000 hours of use, capable of generating significant reductions in city maintenance expenses in addition to energy efficiency savings. The LED lights also maintained cooler temperatures so they could be used without the water, and by design, they were protected from leaking, corrosion, and electrical mishaps.
Energy savings weren’t the only impact of the new lighting system. The fountain became an instant social media sensation, and more foot-traffic began to frequent the square.
- The new lighting system is expected to reduce the lighting portion of the utility bill by 80%.
- Over $5,000 per year in material and labor expenses will be avoided by reduced maintenance.
