A Profile-Based Identification of Standby and Useless Electricity Consumption in Buildings

Useless electricity consumption is the electricity consumption of an electric appliance or system that is not performing its primary function or that is performing its primary function without being useful. So, useless electricity consumption does not only consist of standby losses. To identify the useless electricity consumption in a building, a profile-based approach is developed. This approach is used to investigate the useless electricity consumption in five buildings of the University of Leuven. The result of this study is that in these buildings the useless electricity consumption accounts for 4 to 13 % of the total electricity consumption. This paper will give a detailed discussion of a case study in a library of the university.
