More and more buildings and apartments are constructed considering energy efficiency in Germany. Therefore a comprehensive observation of continuous consumption data is needed. Just some easy interfaces and simple hardware can visualize this data. The installed systems used as a client offer a great added value for a minimalistic server based on raspberry pi.
GLR-Group (Gesellschaft für Leit- und Regeltechnik mbH), located in Papendorf, realizes the implementation of 204 residental units for a customer. Good experiences have already been made in the year before while implementing another project including 60 apartments. The utilized 7”system shows the consumption data of heating and an air conditioning system, electricity and water and revalues the apartment with low cost for the modern system.
