The area of energy management pursues his tasks with the goal of the energy needs of all users as possible to cover completely and optimally. To fall within the field of energy anything that has to do with energy-related production units. This includes, for example, is security of supply, continuous power supply without interruption, the voltage quality, low electricity prices and the integration of environmental aspects (for example) CO 2 – Certificate of Trade. In general, a distinction in the energy sector of the four application fields. First, the energy management for municipalities here involves the use of energy within a municipality or a municipal building, reducing the long term. Then the sector of energy management for industry and commerce, as the third sector, then comes the energy for housing. As the last segment is still different energy management for facilities such as police stations, hospitals or department stores because these are so-called complex function building.
As a first step, is also planning, this distinction is made between the overall concept and detailed designs. To the area of the detail concept includes issues such as thermal insulation, heat insulation, combined heat and power or to meet the electricity demand. It listed total concept and strategy concept, to give priority to explain the overall objectives of energy management. Possible targets could include the independence of energy supply or cost, at just two examples. This step is followed by the inventory and evaluation. Here one deals with the collection and analysis of energy consumption, the investigated property. If completed, this section is working towards a holistic approach that coincides with the strategic plan, the current and future energy needs. Important point here is the detail given to the possible approaches a lot of attention and respect will allow them to be optimally prepared to carry out a final version to be able to account. At the planning phase will be then the practical implementation of the concept of energy. The reaction is carried out taking into account the overall concept and the detailed concepts. In implementing the use of control technology proves to be extremely helpful to control the production units, but can control it.
