Case Study: Energy Audit And Implementation
At The Russell Medical Center

Abstract
An energy evaluation at Russell Medical Center in Alexander City, Alabama was
undertaken by the senior author as a part of a senior design class at Auburn
University. Eight students (Chase O’Mary as their group leader) worked for
eight months performing energy evaluations for all parts of the system. Based
on their findings, recommendations for changes to reduce energy use and cost
were made throughout the period. The largest savings were found in the
following areas: Use of free cooling, consolidating chillers and boilers, better
control of outside air, eliminating simultaneous heating and cooling, temperature
reset, cooling tower optimization, setback in unoccupied zones, and control of
evaporation from heated therapy pools. Partial implementation of these
recommendations resulted in more than an actual 23% reduction in natural gas
usage and a 40% reduction in electric usage. Detailed results from all these areas
are presented. This project is being continued until present. Current focus is on
determining causes for not sustaining initial improvements and better
understanding of impediments to full implementation of recommendations as
well as an update on the current status of the project.
