Use this engineering calculation for a transparent preliminary estimate or independent arithmetic check when geometry, materials, loads, operating conditions, and units are defined consistently.

Sum Individual Peaks Watts (W)

Required number input.

Coincident Peak Watts (W)

Required number input.

Electrical load diversity factor as sum of individual noncoincident peaks divided by coincident system peak. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Diversity Factor

The resulting diversity factor returned as a number.

• Electrical diversity is an empirical planning assumption, not a physical guarantee. Occupancy, operating schedules, controls, seasonal peaks, future loads, power factor, harmonics, and code-required demand rules determine the design load.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check assumptions against drawings, measurements, current material data, and the applicable design code. Apply required load combinations and safety factors, then obtain qualified review and testing for consequential designs.

• Chiller Cop

  Chiller coefficient of performance as cooling output divided by electrical input power, in matching power units.

• Daylight Factor

  Daylight factor as indoor daylight illuminance divided by simultaneous unobstructed outdoor illuminance, in percent.

• Fuel Cell Efficiency

  Fuel-cell electrical efficiency from electric output energy divided by fuel lower-heating-value input energy.
