Technology has advanced exponentially. However, we see many utility plants are designed utilizing "Rule of Thumb" established many years ago. This paper will review the "Rule of Thumb" that consultants utilize on our industry and will provide guidelines on how to optimize the system by design utilizing the latest technology.

For the cooling system, the paper will discuss existing rule of thumb for cooling tower system, chilled water supply temperature, chilled water control systems, and cooling load estimates.

For backup/emergency power, the paper will discuss the mostly proactive state-of-the-art system of utilizing Automatic Transfer switches, "ATS" vs. the utilization of smart breakers.
