We will present the software application VISUAL-TimePAcTS/energy use. The application shows, in a flexible way, the energy use of individuals, households, groups and whole populations which is calculated through individuals’ performed activities. Input data is diary logs for the 24 hours of the day. There are several visualizations opportunities. First, all activities performed by each individual in the population can be shown. Second, activity patterns (i.e. combinations and repetitions of activities) can be identified and represented. Third, the activities that request energy for their performance can be visualized. Fourth, “load curves” that show the power demand can be constructed, within the application, from a set of rules relating energy consumed by different appliances to performed activities requiring these appliances. We will also present principles used for doing the activity categorization (a categorization scheme), and how we hope to develop the software further. The application opens new opportunities to make use of national time use surveys.
