Project Description

Performance Contract Commissioning, UNC Charlotte

GEI’s was retained as the Commissioning Authority for an Energy Savings Performance Contract (ESPC) for the Energy Services Company (ESCO). Various Energy Conservation Measures (ECMs) were performed as part of the ESPC at Barnard, Cameron, Central Steam Plant, Colvard, Fretwell, Garringer, Reese, RUP-2 and Storrs Hall.

ECMs Include:

  • DDC Controls Upgrade
  • AHU VFD Implementation
  • Cooling Tower Replacement
  • Chiller Plant Optimization
  • Main Steam Plant Boiler Replacement
  • Chiller Plant Modifications
  • Steam System Downsizing

 

Chiller Plant ECMs

    • Boiler Decentralization & Replacement at Central Steam Plant
    • New convertible steam/hot water boiler to meet reduced load at central plant due to decentralization
    • Energy savings occur due to higher efficiency remote boilers at various buildings

Chiller Plant Modifications

  • Variable Frequency Drives added to secondary CHW pumps
  • Removal of existing chiller and cooling tower and tie-in to existing CHW plant.
  • 3-way to 2-way CHW valve conversion
