Industrial Laundry, Uniform & Textile Rental Operations worked example

Dryer Energy Cost at 110% production scope charged to dryers: a worked example in industrial laundry, uniform & textile rental operations

This scenario runs the dryer energy cost calculation on the strong side: 110% production scope charged to dryers, with every other input held at its documented default. Built for production supervisors, maintenance managers, and finance teams reviewing tumble dryer cost after extraction by goods mix or shift.

The inputs for this scenario

  • Dryer energy used: 640 therms (unchanged)
  • Energy cost per therm: 1.15 $ / therm (unchanged)
  • Production scope charged to dryers: 110 % (raised for this scenario; the documented default is 100)
  • Fixed dryer service cost: 450 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable dryer energy cost = dryer energy used × energy cost per therm × production scope charged to dryers) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,260 $ for total dryer energy cost, the number this scenario is built around.
  • At this operating point the engine returns 1.97 $ / therm for dryer energy cost per therm used.
  • At this operating point the engine returns 810 $ for variable dryer energy cost.
  • At this operating point the engine returns 450 $ for fixed dryer service cost.

How this compares with the baseline

  • Against the tool's baseline example, where production scope charged to dryers sits at 100% and the headline result is 1,186 $, this scenario comes in 6.21% above the baseline at 1,260 $.
  • Use it for utility allocation, account-level cost-to-serve, and evaluating gas-price or efficiency changes. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total dryer energy cost: 1,260 $ (headline result)
