The EIU ExperienceThe 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
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
The EIU ExperienceThe EIU Experience
A Remaining EIU A Remaining EIU Sustainability OpportunitySustainability 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
2. Over $14,000,000 in deferred maintenance cost avoidance from investing in a new CHP
3. Abundant, sustainable, environmentally soft, local and low-cost long-term energy source
4. 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 CommentsSustainability 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 communityMotivate employees and users to conserve- fight apathy!
Aggressively develop all no-cost/low-cost opportunitiesMany small opportunities usually exist but are ignored
