Saving electrical energy at your site not only lowers your operating costs, but saves California’s
environment. By implementing all of the above recommendations you can potentially save as much
as 589,413 kWh per year and DEER peak demand savings of 32.0 kW. This translates into an
estimated 267.4 metric tons of Greenhouse Gas that will not be emitted into California’s
atmosphere.

PROPRIETARY INFORMATION
The Field Fresh Foods facility is located in Gardena, California approximately 11 miles south of Los
Angeles and approximately 9 miles inland from the Pacific Ocean. Field Fresh Foods serves the
western United States, providing service, distribution and manufacturing that is based around
freshness rather than shelf-life. Every
vegetable is cut to order. Besides
individual raw vegetables, the company
also provides fresh vegetable platters
and mixed green salads.
Gardena is in Climate Zone 8. For the
purpose of this evaluation, this facility is
considered Type 33 – Refrigerated
Warehouse.
Building 1 used 2,383,274 kWh over
the past year, an average of 198,606
kWh per month. The peak demand was
403 kW, while the average demand was 360 kW. The average monthly bill for this account was
$23,758.38 at an average of $0.11963. (See the annual usage and demand in the charts below.)
Project Information
The Field Fresh Foods facility covers an area of ~3.5 acres containing about 70,550 square foot (SF)
of refrigerated warehouse and approximately 10,000 SF of office/mechanical and maintenance area.
The refrigerated warehouse areas are broken up into many smaller areas, each cooled by one or two
small compressor/condenser units and multiple evaporator units. The evaporator fans vary in size
from ¼-hp to ¾-hp each and the quantity of fans per evaporator unit varies from 2 to 5. These fans
run continuously, even when the condenser unit is satisfied and shuts down.
This project is Phase 4 of a multiphase project. In the previous phases, the fans were replaced with
fans having electronically commutated (EC) motors for more efficient operation and the ability to vary
the speed of the fan. In addition, controllers were added to each evaporator unit to control the fan
speed, operating the fan speed at 100% when the condenser unit is cycled on and reducing the fan
speed to approximately 25% percent when the condenser unit has cycled off. Although the customer
achieves savings from changing to the EC motor driven fans, these savings are not recognized by the
program. Therefore, program savings are based on reduced operating hours of the EC motor driven

fans when the condenser unit is cycled off and the reduced heat load added to the room by reducing
the operating hours of the fans, thus enabling the condenser units to remain off for an extended
period of time.
Through phase 3, a total of 98 evaporator fans have been replaced and controlled with program
savings of 248,248 kWh and 4.61 kW demand reduction.

Phase 4 - Building 1 adds sixteen more evaporators and (61) fans to the total units controlled.
In addition to the evaporator fan controls, replacement of sixteen existing evaporator fan coil units has
been recommended. These units are sized to meet or exceed the estimated room loads while
requiring substantially less energy for the evaporator coil fans. Finally, this project evaluates the
replacement of several existing refrigeration condensing units.
