Space Payload & Avionics Manufacturing worked example

Cleanroom Assembly Load with cleanroom assembly connected load of 30 kW: a worked example

This scenario runs the cleanroom assembly load calculation on the strong side: cleanroom assembly connected load of 30 kW, with every other input held at its documented default. Use it when cleanroom assembly load in space payload and avionics manufacturing is up for an upgrade and you want a defensible savings story.

The inputs for this scenario

  • Cleanroom Assembly Connected Load: 30 kW (raised for this scenario; the documented default is 12)
  • Cleanroom Assembly Runtime: 8 hr (unchanged)
  • Blended Electricity Rate: 0.12 $ / kWh (unchanged)
  • Assemblies Built in Runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total cleanroom assembly load energy cost = cleanroom assembly load connected load × cleanroom assembly load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for cleanroom assembly load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total cleanroom assembly load energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly cleanroom assembly load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where cleanroom assembly connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • Use it when costing cleanroom overhead into a build, sizing power and HVAC for a new cell, or evaluating whether a lightly loaded room is worth keeping energized. 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

  • Cleanroom assembly load energy used: 240 kWh (headline result)
  • Total cleanroom assembly load energy cost: 28.8 $
  • Energy cost per kWh: 0.03 $ / piece
  • Hourly cleanroom assembly load energy cost: 3.6 $ / hr
