In September, a pair of CTA mechanical engineers presented at the Food Marketing Institute‘s (FMI) 2014 Energy & Store Development Conference. Their expertise in retail refrigeration systems led FMI to invite CTA principal and Retail vertical market leader Rob Arthur and Refrigeration service sector leader Caleb Nelson to present at this year’s event in St. Louis, MO.

Nelson’s presentation was co-authored by Neil Monson of Target Corporation and Paul Torcellini of the National Renewable Energy Laboratory (NREL). It covered the specifics of an ASHRAE guide — one Nelson and Torcellini helped develop — that lays out steps for achieving high levels of energy efficiency through a focus on proper commissioning and implementation.

“Commissioning has typically been thought of as something someone does after a project is finished to see if it meets owner project requirements and is operating correctly.  However, if you find an issue after the system has been built, installed, and is running, it’s probably too late to fix it economically,” Nelson said. “My presentation was all about finding issues before they’re realized and changing the paradigm to think of commissioning as an integrated process through the entire life of the project.”

Several topics were addressed in Arthur’s presentation:

  • Practices for coordinating and completing refrigeration designs that provide the best opportunity to be installed and operated as intended
  • Refrigeration design processes that work best for organizations of varying sizes
  • Systems most likely to be used in the U.S. in the next five to 10 years that will address energy efficiency, sustainability, refrigeration phase-outs, and serviceability; and a business case to address these items

Arthur noted conference-goers’ high level of interest in understanding and determining the life cycle costs of different refrigeration systems so that retailers can better plan for what systems they will use in the future.
