Restrictions
None
Dependencies
The Sampled Appliances & Occupancy requires the Appliances to be configured.
Outputs
Sampled Appliances & Occupancy is an optional configuration for the Behavioural Water Use node.
Properties
| Property | Description |
|---|---|
| Occupancy Probability | Set the probability distribution (percentage) of houses for each occupancy (0 to 6 people) as either a constant or a time varying distribution |
| End-use Probabilities | Set the probability distribution (percentage) for each appliance type in each end-use category (shower, dishwasher, hand tap, toilet, washing machine, pool) using either a constant or a time varying distribution. |
Constraints
The probabilities in each occupancy and end-use section should sum to 1 and cannot sum to greater than 1. If the probabilities sum the less than 1, an error will be reported in the Log Reporter, but the model will still run. If the probabilities sum to greater than 1, an error will be reported, and the model will not run.
User Interface
Sampled Appliances and Occupancy is configured via the 2. Urban Settings menu. By default, Sampled Appliances and Occupancy is disabled and it must be enabled before it can be edited.
The user interface is illustrated in Figure 1 and the options are described in Table 1.

Table 1. Sampled Appliances and Occupancy menu options.
| Option | Description | Access |
|---|---|---|
| Enable/Disable Sampled Appliances & Occupancy | Enable or Disable the Sampled Appliances & Occupancy menu (disabled by default). Enabling Sampled Appliances & Occupancy will disable the Fixed Appliances & Occupancy model for all Behavioural Water Use nodes in the Urban Scenario. | Right-click on the Sampled Appliances and Occupancy menu item to open the drop-down menu and select Enable or Disable |
| Fixed Probability Distribution | Set the probability distribution (percentage) for each appliance/occupancy type. As you enter the numbers, the graph will dynamically re-draw, showing you the relative probabilities. | Select the Occupancy or end-use category (Shower, Dishwasher, etc) menu item and enter the probabilities in the table. |
| Time Varying Probability Distribution | Set the (optional) time varying probability distribution (percentage) for each appliance/occupancy type. If a time-varying probability distribution is configured, it will override the fixed probability distribution. As you enter the numbers, the graph will dynamically re-draw, showing you the relative probabilities. | Select the Time Based Distribution sub-menu item for each Occupancy or end-use category (Shower, Dishwasher, etc) and enter the dates and probabilities in the table. |
| Export/Import Sampled Appliances & Occupancy | Import and export Sampled Appliances & Occupancy configurations using the JSON file format. | Right-click on the Sampled Appliances and Occupancy menu item to open the drop-down menu and select Export or Import |
| Export/Import Time Based Distribution | Import and export time-varying probability distributions for occupancy and end-uses using the CSV file format. | Right-click on the Time Based Distribution sub-menu item to open the drop-down menu and select Export or Import |
Technical Details
The application of the Sampled Appliances & Occupancy model to simulate the spatial variability in water use events is described in the behavioural model.
