Project Title: Replacement of Lighting Fixtures with LED Energy Efficient Lights at the
Parking Facility. Milwaukee, Wisconsin
Project Location: Potawatomi Bingo Casino Parking Facility, Milwaukee, WI
Principal Investigator: David Brien, Facilities Director and James Borgealt, Electrical Services Manager
The original scope of this project was to replace all the 1,720 205-Watt Metal Halide-type lights
at the Forest County Potawatomi Community's (the "FCPC" or "Tribe") parking facilities located at the
Potawatomi Milwaukee Bingo Casino, Milwaukee, Wisconsin, with state-of-the-art, energy efficient 55-
Watt 11D lights. The Tribe owns a six-story parking structure adjacent to its Milwaukee Potawatomi
Bingo Casino operation (the "Casino") and a valet parking facility that is located under the Casino
(collectively the "Parking Facilities"). Starting on August 30, 2010, the Tribe replaced a total 1,760 light
fixtures in the Parking Facilities, 40 more fixtures than originally proposed, in two stages: first 1,664
lighting fixtures in the parking ramp areas of the 6-story structure and the valet parking area were
replaced; then an additional 96 fixtures were replaced in the parking structure stairwells.
The energy efficiency objective of this project is to reduce the total electrical energy demand in
the Parking Facilities by approximately 50% by upgrading the lighting fixtures. For safety reasons, most
of the Parking Facility's lights are operated 24 hours per day, 7 days per week. Because of this safety
requirement, lighting is the primary energy demand for the Parking Facilities. The Tribe tracks its energy
use on a quarterly basis, and in the year preceding implementation of this project (July I, 2009 to
June 30, 2010) the total annual electrical load for the Parking Facilities was 4,216.000 kilowatt hours
Implementation of the project has resulted in an immediate average reduction in monthly peak
demand of 238 kW over the fourth quarter of 2010. Seasonal variability makes the total annual reduction
in electrical energy use hard to predict accurately at this time. Based on all 1,760 fixtures operating 24
hours per day, the energy savings would project to be 2,313,000 kWh per year. I however, as an energy
saving feature, the Casino already operates the fixtures located towards the periphery of the parking
ramps and on the ramps' roofs only during night time. This energy saving feature, already implemented
at the Parking Facilities, will lower the net reduction in electrical energy resulting from this project. The
average reduction in monthly peak demand from October 1 through December 31, 2010 translates into a
forecast annual electrical energy reduction of approximately 1,995,000 kWh or 47.3% of the pre-project
demand. Tile Tribe will continue to track its energy use at the Parking Facilities through 2011 allow, ing
the Tribe to calculate the actual on-going electrical energy savings at the Parking Facilities that result
from this project.
This project was technically effective and economically feasible and beneficial to the public not
only in terms of long-term energy efficiency and associated emissions reductions, but in the short-term
jobs provided for the S.F. Wisconsin region. The project was implemented, from approval by U.S.
Department of Energy ("DOE") to completion, in less than 6 months. The project utilized off-the-shelf
