Anatomy of a
Performance Contract: Saves College Big Energy Bucks
Gary Reed was never a
wait-until-it-breaks type of guy. So when he became the utilities
manager for Eastern Illinois University (EIU) in 1989 and saw the
old facilities he was going to maintain, Reed knew he had his work
cut out for him. The 1960s-era utility systems were ancient by
modern standards and terribly inefficient. The result: steep energy
bills and a frail infrastructure.

The latest
10-year project began in 2003 at a cost of $2.6 million.
Annual energy savings are expected to be $295,142 for a
projected total savings of $2.9 million. |
Reed accepted the
challenge. There was one tiny problem though, limited funding
options hindered him from pursuing many conservation opportunities.
Like many higher education facilities, deferred maintenance had been
piling up at EIU for years and given the State of Illinois’ fiscal
condition, there was not much relief in sight. It was basically a
typical facility management nightmare: having to manage major
educational facilities with a huge deferred maintenance backlog,
aging infrastructure and a limited budget. This forced the
university into a “run-until-it-fails” maintenance mentality that
resulted in inefficient operations, unreliable systems and a
perception of poor customer service delivery.
So when the state invited EIU to explore energy savings performance
contracts in 1994 — which were an emerging method of upgrading
utility systems without paying any upfront capital costs — the
university jumped at the chance.
Ever since, EIU has become a model of energy efficiency thanks in
large part to a series of performance contracts. In 2004, the
Illinois Department of Commerce and Economic Opportunity (DCEO)
cited the school in a report to the Illinois General Assembly as
having the lowest energy cost per-square-foot amongst all Illinois
public universities. Ultimately, being more energy efficient helps
the university avoid having to pass the cost of new equipment and
energy rate increases on to students and
Illinois taxpayers.
Performance contracts are agreements between a facility owner and an
energy services company (ESCO). The ESCO engineers and implements
facility improvements at no up-front cost, and guarantees a minimum
level of energy savings from the upgrades and retrofits. The ESCO
also can help the company secure financing based on that guarantee,
as well as provide ongoing maintenance and monitoring services to
ensure that energy savings are achieved.
The typical performance contract term runs from eight to 15 years
(the term is 10 years for Illinois colleges and universities). The
savings from reduced utility bills are used to pay for the capital
investment in equipment, installation and related financing fees.
The facility retains 100 percent of the savings to use at its
discretion at the completion of the contract. If the guaranteed
savings are not realized during the term of the agreement, the
ESCO is obligated to pay the difference — meaning the participating
institution is at no risk.
Although, critics remain skeptical about whether performance
contracts can achieve the savings they guarantee, institutions like
EIU are proving they can work and EIU’s strategy has become a good
blueprint.
As part of a pilot program initiated by then-Governor Jim Edgar, EIU
entered into its first performance contract in 1994. Work under the
10-year agreement included upgrades to lighting, heating,
ventilation and air-conditioning (HVAC), and building automation.
Over time, the university was able to use an alternative avenue of
funding by leveraging the utility savings to buy immediate capital
improvements and help reduce deferred maintenance.
In recognition of the success of the project, the DCEO awarded EIU
the State of Illinois Energy Efficient Building award in 1997.
The original contract blended basic improvements that had short
energy paybacks (lighting improvements) with more complex
opportunities offering longer paybacks (energy management system
upgrades). EIU decided to hold off on more aggressive changes for
the future.
EIU began planning for a second, more comprehensive project in 2000
and before beginning the work, the ESCO conducted an investment
grade audit to determine improvements that needed to be made.
The project price tag was $10.8 million, but the plan has guaranteed
an annual savings of nearly $1.2 million for 10 years. That means
that if the energy conservation measures continue to perform as
expected for the duration of the agreement, savings over the life of
the performance contract (around $12 million) will exceed the
installed cost of the project.
The scope of this project was aggressive and wide-ranging.
Fluorescent lighting systems were replaced or upgraded in 30
buildings, including new electronic ballasts, T8 fluorescent lamps
and light-emitting diode (LED) exit signs, all of which use less
energy and have a longer life span than the old systems. A new pool
filtration system in a recreation center was installed and
comprehensive water retrofits in 33 campus buildings were also
provided. These retrofits included new low-flow toilets,
reduced-flow showerheads, faucet restrictors and aerators and new
more efficient washing machines.
One of the biggest parts of the project was replacing seven
30-year-old absorption chillers with four new electric chillers.
Along with the new chillers, chilled water piping modifications and
new pumps with variable frequency drives (VFDs) in 10 buildings were
provided. The upgrade addressed more than $4 million in capital
renewal needs and mitigated the liability of major equipment
failure. Two underground piping systems were extended to tie
buildings together on common chilled water loops.
The project also expanded the university’s existing building
automation system—new variable air volume (VAV) controls, VFDs and
high- efficiency motors were installed on 50 air-handling units. In
addition, these units were rebalanced and re-commissioned to
significantly improve comfort control and restore proper ventilation
rates.
While the facility and systems upgrades were noteworthy, it was the
impact on operating budgets that drew attention. In 1998, the energy
cost per square foot at EIU was $1.40 — according to the Illinois
DCEO — which was middle of the pack for public universities. By
2003, the figure was down to $0.99 per square foot, the lowest in
the state and more than 40 percent lower than the average. In its
report, the DCEO cited the strong track record of implementing
energy performance contracts and energy conservation measures as
reasons for the school’s lower costs.
In one of the latest projects, wrapped up in 2005, the school
implemented advanced control strategies to make its chilled water
loops and airhandling systems even more efficient. For example, a
global control strategy was implemented to optimize the campus’
chilled water loops. Indoor air quality sensors that determine how
many people are in a building by measuring carbon dioxide levels,
and then vary the amount of outdoor air introduced into that
building accordingly were also installed.
Another system is allowing facility users to monitor automation
systems through the Web. Minor adjustments are possible to keep
particular rooms at comfortable temperatures while they are occupied
outside of normal business hours. New cooling coils in several
air-handling units are also helping to improve cooling and humidity
control.
The latest 10-year project began in 2003 at a cost of $2.6 million.
Annual energy savings are expected to be $295,142 for a projected
total savings of $2.9 million.
The concept of creating a self-funding mechanism derived from
utilities savings that could also solve major deferred maintenance
challenges on the campus would have seemed impossible just a handful
of years ago. But now, Eastern Illinois University can be looked at
as a model for the successful use of performance contracts.
