Sampled Appliances & Occupancy

This section describes how to configure the Water Use node for sampled appliances and occupancy.

1 Select Configure > Water Use > Sampled Appliances and Occupancy from the Urban Developer main menu. The Sampled Appliances and Occupancy window opens:

Set the probability distribution (percentage) of houses for each occupancy (1-7 people). In the example window, above, 11.3% of houses have one occupant, 22.7% of houses have two occupants, etc.

3 Set the probability distribution (percentage) for each type and efficiency of water use (ie shower, washing machine, etc). BESS randomly assigns the appliance type and occupancy to each house based on these percentages. In the example above, 35% of households have 0-Star showers, 45% have 1-Star showers, etc. As you enter the numbers, the graph also dynamically re-draws itself, showing you the relative probabilities.

Note The probabilities in each appliance section should sum to 1 and cannot sum to greater than 1. If the probabilities do not sum to 1, the numbers, and the graph, will be coloured red, but the model will still run. If the probabilities sum to greater than one, a warning message appears, and the model will not run.
