May 8, 2014 – Columbus, OH


The Ohio Center for Industrial Energy Efficiency, Duke Energy, DP&L and AEP are pleased to offer the 1-day class Introduction to Energy Efficiency in Chiller Plant Systems. Students attending the one-day workshop will learn:

  • The fundamentals of chiller plant systems
  • To apply a systems approach to improve energy efficiency in chiller plants
  • Predictive and preventive maintenance best practices
  • To identify and prioritize energy conservation measures in chiller plants

This workshop will provide fundamental information in a practical manner to chiller plant operators, utility engineers, supervisors, energy managers, consultants, etc. Hands-on exercises that provide an ease of understanding the issues and economic impacts associated with chiller plant operations.

The workshop uses actual operating data from existing chiller plant to demonstrate the impact of energy conservation measures. Students will have the ability to take some of the Fault Detection and Diagnostics (FD&D) techniques and directly apply them at their facility.

The students are expected to bring basic information of their chiller plant system to allow them to better understand and comprehend the course. Additionally, group discussions and one-on-one interactions with the instructors will be highly encouraged.
