The discussion for upgrading a chilled water plant begins for a number of reasons including repurposing a building, utility rates or dated equipment. A U.S. DOE-funded study concluded that commissioning is indeed cost-effective for both new and existing buildings with potential energy cost saving of over $18 billion. This ENL program will provide designers with specific strategies for chiller upgrades, optimization or replacement. We’ll discuss reusing components of a chilled water system and identify areas where control upgrades would be beneficial.

Learning Objectives:

  • Identify opportunities to upgrade or repurpose chillers
  • Summarize the opportunities various design strategies offer existing systems
  • Explain how to apply the use of variable flow in existing systems
  • Identify and apply control strategies to optimize and reduce system energy use and lower energy costs
