The EIU Experience
SUMMARY OF BENEFITS TO EIU

Annual savings guaranteed: $2,017,000
 Annual savings expected: $2,303,000


Net annual to reinvest: $286,000
$16.7M in infrastructure, systems and
performance improvements paid from savings
over 10 years
 Out of that sum, $13.2M applied to deferred
maintenance reductions
The EIU Experience
BENEFITS TO THE ENVIRONMENT







CO2 emissions reduced by 64,000 tons per year
SO2 emissions reduced by 600 tons per year
NOx emissions reduced by 240 tons per year
Lower fresh water resource usage
Lower waste water generation
Lower landfill input
Lower overall thermal rejection to ambient
A Remaining EIU Sustainability
Opportunity

10MW Combined Heat and Power (CHP) plant
(new 20-year duration EPC will play a MAJOR
part in making this feasible for EIU: RFP is now
on the street)
1.
Base-fueled with biomass with possible capability to “flex” to alternative
fuels with minor re-tooling
Over $14,000,000 in deferred maintenance cost avoidance from investing
in a new CHP
Abundant, sustainable, environmentally soft, local and low-cost long-term
energy source
Leverage additional ECMs in this project to support the CHP such as
higher voltage metering, science lab ventilation, chilled water upgrades,
BAS optimization, lighting, water, etc.

Sustainability Comments



Support LEED concepts in the Capital project process
Vigorously develop 20 year EPC opportunities (new
legislation was a great move!!)
Continuously improve maintenance skills through training
The best energy saver is a “world class” maintenance program

Incorporate sustainable energy sources such as wind, solar,
geothermal, biomass
Accept the fact that these options may feature more complicated
infrastructure, high front-end costs and long paybacks

Building use schedule/temperature optimization (BAS)
Can easily conflict with expectations of the customers

Engage the campus community
Motivate employees and users to conserve- fight apathy!

Aggressively develop all no-cost/low-cost opportunities
Many small opportunities usually exist but are ignored
