Energy Label Compliance Burden with connected load of compliance test rig of 20 kW: a worked example

This scenario runs the energy label compliance burden calculation on the strong side: connected load of compliance test rig of 20 kW, with every other input held at its documented default. Use this when budgeting the energy cost of running compliance testing in your lab, comparing in-house vs. third-party lab cost, including energy burden in fixture certification overhead, or justifying investment in more efficient test equipment.

The inputs for this scenario

  • Connected load of compliance test rig: 20 kW (raised for this scenario; the documented default is 8)
  • Total test runtime for the batch: 16 hr (unchanged)
  • Facility electricity rate: 0.13 $ / kWh (unchanged)
  • Fixtures tested in this batch: 12 fixtures (unchanged)

Working through the calculation

  • Applying the documented formula (Total compliance testing energy cost = test load (kW) x runtime (hr) x electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 41.6 $ / unit for total compliance testing energy cost, the number this scenario is built around.
  • At this operating point the engine returns 320 kWh for compliance test energy consumed (kwh).
  • At this operating point the engine returns 3.47 $ / piece for compliance energy cost per fixture.
  • At this operating point the engine returns 2.6 $ / hr for hourly test equipment energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where connected load of compliance test rig sits at 8 kW and the headline result is 16.64 $ / unit, this scenario comes in 150% above the baseline at 41.6 $ / unit.
  • Use it when costing a certification program, sizing test batches, or evaluating the overhead of adding a new labeled SKU. 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 compliance testing energy cost: 41.6 $ / unit (headline result)
  • Compliance test energy consumed (kWh): 320 kWh
  • Compliance energy cost per fixture: 3.47 $ / piece
  • Hourly test equipment energy cost: 2.6 $ / hr
