ADJUSTMENT

eCalc Model / FACILITY_INPUTS / ADJUSTMENT

Required	Child of	Children/Options
No	FACILITY_INPUTS	CONSTANT FACTOR

Description

For various reasons (degenerated equipment, liquid pumps, etc.), the predicted energy usage from the facility input does not always match the historic usage. To account for this, adjustments may be added to the facility input. Currently, linear adjustment to the energy usage is supported.

warning

Even though The ADJUSTMENT factor and constant can be added to any FACILITY_INPUTS, it is only implemented and used for a small subset of equipment, namely: SAMPLED COMPRESSOR MODEL, TABULATED ENERGY USAGE MODEL, GENERATORSETS , PUMP MODEL (Single Speed, Variable Speed and System) and compressors in a compressor system. If you are not sure, give it a test first.

Format

ADJUSTMENT:
  <ADJUSTMENT 1>: <VALUE>
  <ADJUSTMENT 2>: <VALUE>

Example

Say you have input that is off by a constant and percentage. You could fix this in the following way:

NAME: some_facility_input
FILE: filename.csv
TYPE: FACILITY_INPUT_TYPE
ADJUSTMENT:
  CONSTANT: 2
  FACTOR: 1.05

The resulting energy consumption $E_\mathrm{adjusted}$, i.e. fuel or power, will then be

$$E_\mathrm{adjusted} = 2 + 1.05 \times E_\mathrm{original}$$

where $E_\mathrm{original}$ is the energy consumption before the adjustment.
