Best Methodology (Nike) Energy & CO2 Program:
Complex methodologies and ideas
Eliminate old system (reduce energy loss by 10%)
Project 1: Insulate mold presses
Project 2: Reduce mold mass
Project 3: Install six-sided platen
Project 4: Auto loading mechanism
Project 5: Purchase small boilers
Project 6: Develop energy pull system
Savings of >60% energy & CO2
Extremely fast payback (<1 year). Reduced cycle time.
Saving energy through changing mold

Consists of three activities
Provides a robust starting point for continuous improvement efforts
Report energy data into Nike’s One Tool
One Tool automatically calculates total energy use, carbon emissions, and energy
and CO2 KPIs. Used for minimum energy program, SM KPIs, and Nike carbon
footprint calculations. Establishes baseline for factory energy and carbon program.
Include key energy saving procedures into existing TPM program
Results in substantial energy savings and prevents energy waste
Establish a team to develop and deploy energy saving activities
Team is the foundation of the continuous improvement efforts
