At the moment, the energy demand of households is calculated with standard load-profiles, so called H0-profiles. These profiles are published yearly by for example E.ON for different areas and are then used by the smaller energy suppliers for demand prognosis. They have a resolution of 15 minutes, because the planning in energy economics is also done in this time span. Because of that, devices with shorter usage duration are considered with their mean power over 15 minutes. During the research project "ADRES" an extensive measurement series was recorded. In this thesis it should be compared on basis of the measurement series, whether the daily power consumption for devices used in the creation of synthetic load-profiles is similar to derived characteristics. After a short introduction to the topic of the thesis, the steps during the programming are described. As a result of this programming work, a graphical user interface for easy adjustment of the desired analysis was designed, which is explained after that. As a next step, some literature that was recently published on this topic will be reviewed. The actual analyses are separated into three main sections. In the first section, the usage of single devices is evaluated, in the second one, the whole households are investigated and the third and last one is a trial to extract some of the non detailed measured devices from the sum measurement and describe them. The creation of the analysis is done in respect with trend curves found in the literature. Extensive comparison with the H0-profile is especially done for the sum measurement to evaluate a connection between actually used devices and the widely used H0-profile. Thereby, it should be verified whether the extensive usage of this relatively simple model for households is justified.
