District Energy & Thermal Network Equipment worked example

Controls Commissioning Load with commissioning connected load of 30 kW: a worked example in district energy & thermal network equipment

This scenario runs the controls commissioning load calculation on the strong side: commissioning connected load of 30 kW, with every other input held at its documented default. Use it when controls commissioning load in district energy and thermal network equipment is being quoted and energy is a real chunk of the district energy and thermal network equipment cost stack.

The inputs for this scenario

  • Commissioning connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Controls commissioning runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Control points or stations commissioned: 1,000 points or stations (unchanged)

Working through the calculation

  • Applying the documented formula (Controls commissioning energy used = commissioning connected load × controls commissioning runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for controls commissioning energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for controls commissioning energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per control point or station.
  • At this operating point the engine returns 3.6 $ / hr for hourly controls commissioning energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where commissioning 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 during startup planning to budget the energy cost of functional testing and to benchmark cost per control point. 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

  • Controls commissioning energy used: 240 kWh (headline result)
  • Controls commissioning energy cost: 28.8 $
  • Energy cost per control point or station: 0.03 $ / piece
  • Hourly controls commissioning energy cost: 3.6 $ / hr
