Data about the energy consumption of buildings contains valuable information which is essential for the future energy system and smart cities. However, only few researchers publish the data on which their methods and analysis is based. This lack of publicly available data sets, makes it difficult to compare strategies and results, and hinders a stronger development of the research field. Thus, this paper describes a data set of municipal energy consumption data, which is published with the objective to facilitate the comparability of research methods in the field.
