Description

The energy usage model specifies the data to calculate the energy usage of a consumer. This data is used to set up a function that may be evaluated for a set of time series and returns a result including the calculated energy usage.

The type of energy usage model is defined by TYPE, and which keywords are required/supported will be different for each type. The available types are:

Energy usage model types:

• DIRECT
• TABULATED
• PUMP
• PUMP_SYSTEM
• COMPRESSOR
• COMPRESSOR_SYSTEM
• VARIABLE_SPEED_COMPRESSOR_TRAIN_MULTIPLE_STREAMS_AND_PRESSURES

For all types, the keywords CONDITION, CONDITIONS and POWERLOSSFACTOR are optional and supported, and these will act on the calculated energy usage after the calculated energy usage from the model defined by TYPE.

Temporal energy usage model

It is possible to update the energy model within a consumer over time, as long as the ENERGY_USAGE_MODEL stays within one type. The TYPE cannot change over time. In case TYPE evolution is needed, we recommend that you split the model into two CONSUMERS.
