The Zale Lipshy Hospital chilled water system was originally built in 1988 to provide chilled water to the hospital. Upon discovering that the current plant configuration was not operating at the optimal performance level, UT Southwestern contacted LAN to perform a study to increase the system’s efficiency and reliability. The analysis included a review and evaluation of the current chiller plant operations, control sequences, and building automation trend data.

LAN proposed three operational sequencing recommendations based on energy efficiency and the mechanical reliability of the system. LAN engineers also provided guidelines for improving future chiller plant operations that would yield a 20-30% savings in energy for the hospital.
