Gargiulo Produce


Warehouse Case Study

Established in 1929. 9 year old facility. 175,000 square foot warehouse. Includes significant refrigerated and freezer space.

Business Situation

The Gargiulo Produce warehouse runs 24 hours a day, 365 days a year. The lighting system is comprised primarily of 400 Watt metal halide and high pressure sodium and T-8 fluorescent fixtures. Four TRANE roof top units condition the office space in the facility. Four large refrigeration systems maintain temperatures ranging from -15 degrees to 55 degrees Fahrenheit in the temperature controlled areas. The warehouse’s energy costs were excessive and required immediate relief.

Your systems are consistently saving us 23% and the project has paid back in just 13 months. That is a 92% return on our investment.

Process

As a first step Energy Edge Solutions (EES) conducted a comprehensive whole building investment-grade energy audit and engineering study of Gargiulo’s facilities. The audit included an intense review of the following areas:

Utility Bills: EES reviewed the previous 12 months of utility data for the facility.

Designs: EES reviewed all available electrical one line and mechanical drawings.

Facility Energy Behavior: EES reviewed with the customer the current energy behavior of the staff including temperature set points, setting back temperatures when the facility y is closed, turning off lights, office equipment, etc. after hours.

Building Envelope: EES checked weather stripping, insulation, open doors and areas around frequently trafficked areas, etc.

Lighting Systems: EES reviewed the current lighting systems to determine if the most efficient lighting options were being used and if occupancy sensors, timers and dimmers had been placed into operation. EES also looked for areas that were over lit and areas that could take advantage of natural sunlight.

Heating, Ventilation and Cooling Systems: EES looked at the HVAC/R systems to determine operating efficiency, maintenance schedules, filter replacement frequency, age, and upgrade and treatment options.

Motors and Equipment: EES itemized all electrical loads across the facility (including HVAC, production and refrigeration equipment) and their respective run times. Actual electrical measurements such as amperage, voltage, THD%, power factor, etc were taken at all loads as well as at the main. Load, duty cycles, operating efficiency, age, replacement and treatment options, etc. were all determined.

Solution

Energy Energy Edge Solutions (EES) recommended a whole facility approach to energy cost reduction to significantly reduce the customer’s expenses. Based on EETC’s preliminary analysis, Gargiulo Produce was guaranteed a minimum kWh reduction of 12.12% and a maximum project payback of 32 months. After completion of an in-depth engineering study and project design, EES guaranteed to reduce Gargiulo Produce’s energy consumption by 14.62% with a payback on the turnkey project of 26 months or less.

Benefits

EETC measures the success of all projects in accord with the International Performance Measurement and Verification Protocol, Option C (www.IPMVP.org) as approved by the U.S. Department of Energy. After completion of the turnkey project and 3 years of measurement and verification, Gargiulo Produce has been enjoying an average annual kWh reduction of 23%. The turnkey project paid for itself in less than 13 months giving Gargiulo Produce a 92% return on investment.
