Case Study – Steam Systems
By conducting a steam survey and checking and repairing steam traps and insulation throughout its manufacturing facilities, Leprino Foods realized approximately $27,390 in annual energy savings.

Case Study – Steam Systems
In 2000, a Wisconsin dairy completed a plant energy audit and, after boiler improvements were made, reduced its natural gas use by 10,500 MMBtu per year, for a cost savings of $39,800 annually.

Case Study – Lighting Systems
In 2009, the Marva Maid of Landover processing plant in Landover, Md. replaced old metal halide, high-pressure sodium and incandescent light fixtures with new energy efficient lighting systems and upgraded to light-emitting diode (LED) exit signs – saving 400,014 kWh per year.

Case Study – Lighting Systems
After a complete analysis of its lighting systems, Leprino Foods replaced metal halide fixtures throughout the plant with fluorescent lamps and sanitary-design fluorescent fixtures, delivering approximately $218,000 in electricity cost savings annually with the same or better light coverage.

Case Study – Lighting Systems
By switching from incandescent lamps to LED lighting in its vintage sign, the Shamrock Farms dairy plant in Phoenix, Az. was able to save 80,500 kWh of electricity per year.

Case Study – Compressed Air
Leprino Foods completed a compressed air study that revealed sources of energy waste. The resulting combination of upgrades, modifications and repairs saved Leprino Foods approximately $157,000 in electricity costs annually.

Case Study – Refrigeration
In 2002, a high-volume ice cream and novelty frozen goods plant in Ohio completed an overall energy audit of its refrigeration systems, reducing the energy use of that system by more than 25 percent -- an annual reduction of 3,368,000 kWh.

Case Study – Reverse Osmosis Filter System
In late 2009, Maryland & Virginia’s Laurel plant replaced two outdated milk evaporators with one reverse osmosis (RO) filter system, significantly reducing the plant’s steam and saving 528,000 therms and an estimated 82,290 kWh of electricity per year.

Case Study – Solar Thermal Systems
Oakhurst Dairy installed 72 solar panels on the roof of its headquarters in Portland, Maine in the spring of 2008. By reducing the energy required to heat water for case washing, the system reduced the company’s heating oil consumption by more than 5,000 gallons per year.

Case Study – Variable Frequency Drives
By adding a variable frequency drive (VFD) to each pump motor, Leprino Foods was able to reduce its energy use from the motors by 50 percent — an annual energy savings of 57,000 kWh per year for each motor.
