CARBON × KAIZEN · Carboka practice lab
Electricity is the digital footprint of equipment
Select a state to explore its power signature. Start with measurement and connect energy to the production context.
Production
What the curve suggests
Load varies with process cycles. Combine orders, cycle timing and good counts to understand energy per product.
What to check at the production site
Align product specifications, processing requirements and complete energy; plan improvement trials with suppliers.
Connect to this lab
IE+E: connect equipment states to process steps and product requirements. Understand necessary work and waiting before planning a trial with suppliers.
Calculations and boundaries
This is an illustrative curve, not measured data or equipment specifications. Power (kW) accumulated over time gives energy (kWh). Product, good output and a complete measurement boundary are still needed to compare energy per unit. A curve alone cannot diagnose faults or prove carbon reductions.
Measure directly where possible. Use models for what cannot be measured directly, and retain assumptions and review records.
Based on whitepaper page 11, “Electricity is the digital footprint of equipment.” Interactive explanations extend the website teaching examples.
IE+E: show brands where each product’s energy goes.
Start with the process. Relate time and energy for the same product batch to identify a useful investigation with suppliers.
Teaching scenario · Editable calculation · Not field results
A starting point for brands: use process energy data to examine specifications, tolerances and processing requirements with suppliers, and identify a traceable improvement trial.
01 Adjust the scenario
EX04: the same hypothetical product, 100 good units observed at each station, no defects or rework. Direct energy is 6, 42, 5 and 9 kWh; work times are 12, 38, 10 and 16 seconds per unit.
Inputs are calculated on this page only. They are not uploaded or saved automatically. Reloading restores the example.
02 Read the results
Direct batch energy (kWh): — · Percentage of total direct electricity consumption: —
Compare each process: share of work time and share of direct electricity consumption
The shares of work time and electricity consumption can differ. Investigate high consumption by checking required processing, waiting time and product requirements.
Calculations and boundaries
Add the direct electricity consumption of all four workstations, then divide by the conforming product count in the same batch. The EX04 value of 0.620 kWh/unit excludes shared utilities and consumption outside the observation period. It is not the complete product energy intensity and must not be combined with EX01. The 76 seconds is the sum of work times, not the output cycle time of a parallel production line.
03 Put it into practice
Explore IE+E from my role
Brands can influence product requirements and supplier collaboration.
First ask which process carries the largest direct load. Then investigate specifications, tolerances, materials and processing requirements with the supplier. Align product, quality, boundary and batch before comparing. Use the result to plan a joint trial, not to rank suppliers from this example.
