Evaluate an action

To evaluate an action, you can specify its evaluation method at creation.

In the case of an action with no existing evaluation, you can change the method via the "Evaluation" tab.

Choosing an evaluation method

To calculate the benefits of an action, you need to define :

• a performance indicator to monitor the quality of consumption
• a reference period, which defines the normal state of your consumption before action, and which will be used to calculate your reference indicator
• an evaluation period, to calculate your post-action indicator

An action has 3 possible evaluation methods (3 types of indicators):

• Evaluation by consumption: your indicator is defined as a consumption meter divided by time.
  Example: kWh / week
• Evaluation by EnPI: your indicator is defined as a consumption meter divided by a production meter.
  Example: MWh / ton produced
• Evaluation by IPMVP: your indicator is defined as a consumption meter divided by time. The difference with “Evaluation by consumption” is that this indicator is compared with a modeled (theoretical) consumption meter.
  Example: kWh / week

Once your indicator and its reference period have been defined, the application calculates your reference indicator.

For IPMVP evaluation, there is no reference indicator. It is replaced by the theoretical consumption of a model.

Calculating energy savings

Once your action has been carried out, you can indicate its evaluation period. This time range enables the Energiency application to calculate the evaluation indicator.

The difference between the reference indicator and the evaluation indicator is used to calculate the evolution (%) and gain in consumption (consumption unit) following the action.

Calculating the financial gain and ROI

You can fill in the financial fields to automatically calculate the associated financial gain and ROI.

• Investment : the amount spent to implement the action. This value is subtracted from the final financial gain.
• Price of a consumption unit: the price of the energy consumed, expressed in “currency/consumption unit” (example: €/kWh). You can enter a fixed value, or add a meter containing the price as it evolves over time.
  • Please note: the consumption unit must be the same as the consumption meter used in the performance indicator. The currency displayed is defined in the “Settings” area of the platform.
  • This price enables the application to calculate the final financial gain from the energy gain.

• ROI (Return On Investment): the return on investment is calculated automatically, indicating how many years it will take for the financial gain to equal the investment. In the case of EnPI evaluation, ROI also indicates after how many production units (based on the production meter used in the performance indicator) the financial gain will equal the investment.

The results are shown in the action header.
