The evaluation of data plays a decisive role in the Energiewende. Smart meters make it possible, for example, to record and evaluate information about energy consumption. SANDy, a start-up company from EnBW, goes one step further. It provides the technical basis for the targeted examination of huge volumes of data from a variety of areas. SANDy utilises intelligent algorithms to recognise behavioural patterns that can reveal interesting information relating to energy consumption. One of the many applications: heating systems are still being controlled using fixed time schedules, no matter whether anybody is in the room or not. Therefore, SANDy creates a usage profile using sensors that is constantly updated and sent to the heating control system. If large volumes of data are collected and evaluated in this way, it can provide valuable information to companies for the development of new, customer-friendly products. SANDy thus also marks EnBW's entry into the management of large volumes of data.
