Direct Connection to Policy Area 6 <strong>of</strong> The Illinois Commitment<br />
Chiller Project<br />
Southern Illinois University - Edwardsville<br />
What issue or need is addressed by the effective practice?<br />
The former central cooling system for the campus consisted <strong>of</strong> four single-stage, lithium bromide absorption<br />
chillers, one two-state lithium bromide absorption chiller, and two electric driven centrifugal chillers. The<br />
ability to properly cool the campus’ major facilities was dependent on the reliable functioning <strong>of</strong> all <strong>of</strong> those<br />
chiller units. However, the chillers were obsolete (more than 35 years old), no longer energy efficient, and in<br />
extremely poor condition. For example, in June <strong>of</strong> 2000, all four single-stage chillers failed at once, leaving the<br />
campus with inadequate cooling.<br />
Description <strong>of</strong> the effective practice:<br />
As a result <strong>of</strong> this project, the chillers were replaced with a centrifugal chiller and a new chilled water storage<br />
tank that now holds 3.3 million gallons <strong>of</strong> chilled water. The tank utilizes the principles <strong>of</strong> thermal stratification<br />
for chilled water storage and allows chilled water to be produced at night at low utility rates and used during the<br />
day.<br />
How does this practice achieve sustainability?<br />
The cost <strong>of</strong> the project was $5 million and was paid for by state appropriations for SIUE to the Capital<br />
Development Board with additional funding from university operating funds.<br />
What are the results/measurable outcomes?<br />
The project was awarded the Illinois Capital Development Board Chairman’s Award for Programmatic<br />
Achievement in March 2006.<br />
