Experience
The City of Covington is located on the northeastern portion of Kenton County,
Kentucky, directly across the Ohio River from Cincinnati, Ohio. In an effort to
realize significant savings and maximize taxpayer dollars towards building
improvements and becoming green, the City of Covington partnered with Energy
Systems Group to implement over $2.8 Million of energy efficiency and facility
improvement measures throughout the City.
Strategies & Solutions
As a result of the energy performance contract developed by Energy Systems
Group, the City expects to save $5 million over 20 years. “In the first year,
Covington has saved $200,000 in energy costs, about $20,000 more than
anticipated,” said Tom Logan, director of public improvements and city engineer.
Both the city and Energy Systems Group have received national publicity for
the energy-saving efforts implemented, including a front cover story of trade
magazine “Public Works” for a piece heralding the energy-saving performance
contract (ESPC) signed in 2008.
Phase I:
The scope of work for the first phase included facility improvements
for 9 buildings throughout the City, including City Hall, fire stations, the Police
Headquarters, Public Works and parking garages. Technologies to be employed
include lighting system upgrades, vending machine controllers, occupancy sensors,
HVAC system improvements, energy management controls, CO
2
monitoring
controls, variable speed drives and water-efficiency upgrades, among others.
The city replaced some of the 429 city-owned traffic-signal bulbs at 20
intersections plus 182 pedestrian crosswalk lamps with light-emitting diodes,
which draw less power and last 8-10 years rather than 11 months for traditional
bulbs. Also, a new lighting system for the city center parking garage is estimated
to save $14,000 per year. The City of Covington will receive rebates from their
electrical energy supplier to supplement the costs of lighting improvements.
Phase II:
The second phase of the project was funded with $188,000 in federal
stimulus grant money and $400,000 in city capital improvement funds. In the
second phase, the city changed 76 light fixtures in Mainstrasse from 175-watt
mercury vapor lights to 68-watt compact fluorescent lights. The city also replaced
50 lights under overpasses, reducing the wattage from 150-200 watts to 68 watts.
• Lighting System Improvements (4 Buildings, 2 Parking Garages, City Underpasses,
Mainstrasse street & walkways)
• Energy Management Systems and Controls (3 Buildings)
• Water and Sewer Improvements (2 Buildings)
• HVAC Improvements (3 Buildings)
• Windows (2 Buildings)
“Working with progressive
leadership at the municipal level to
provide energy efficiency and facility
upgrade improvements is exciting.
The City of Covington
has demonstrated through this
project that it is focused on energy
issues and we are proud to be
partnering with them providing
creative solutions.”
