3M’s manufacturing facility runs 24/5 with heavy manufacturing loads. Many loads are driven by motors up to 1,000 horsepower each. The lighting system was comprised primarily of 400 Watt and 1,000 Watt metal halide fixtures. Three dozen roof top HVAC units cool and heat the facility in addition to a central chiller plant. The facility’s energy costs were exorbitant and were eating away at the bottom line profitability of the plant.
Senior management is now singing my praises as they see the money we’re saving.

As a first step Energy Edge Solutions (EES) conducted a comprehensive whole building investment-grade energy audit and engineering study of 3M’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 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.
Energy Energy Edge Solutions (EES) recommended a whole facility approach to energy cost reduction to significantly reduce the plant’s expenses. Based on EETC’s preliminary analysis, 3M was guaranteed a minimum kWh reduction of 7.28% and a maximum project payback of 29 months. After completion of an in-depth engineering study and project design, EES guaranteed to reduce 3M’s energy consumption by 8.88% with a payback on the turnkey project of 24 months or less.
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. EES compiles a statistical measurement and verification report quarterly for customers which includes utility bill analysis, base and verification period comparison, building simulation/ modeling, inclusion of all factors of influence, statistical correlation, regression analysis, etc. The turnkey project is currently producing annual energy savings of 10.15% and paid back in less than 19 months, giving 3M a 63% return on investment.
