In its current state, the tool is able to randomly generate the load profile of 15 different appliances according to the characteristics of the household, e.g.. the building type (single family house or multifamily house), the number of occupants (from 1 to 5 occupants) and the appliance stock (type and energy labelling). This random generation of use profiles is based on the Spanish Time Use Data (TUD), a survey done in Spain by the Spanish Statistical Office (Instituto Nacional de Estadística, INE). TUD describes what people do at home over the course of the day, providing occupancy patterns and relating them to the use of appliances (e.g. if the activity is “laundry”, the “washing machine” will be used at that moment).

As an output, the model provides the following information: a) detailed profiles of each appliance’s consumption at 3-minute intervals b) a summary of the annual energy consumption of every appliance; and c) an energy comparison with more efficient appliances.
