The standard underlines the necessary measuring technology infrastructure in order to integrate buildings more efficiently into electrical distribution networks and to enable energy management/energy controlling during operation. It provides notes on device selection@ infrastructure@ and evaluating measurement results. The standard applies to all buildings with the exception of those with industrial use and refers to low-voltage range designs. Measuring technology for the medium-voltage range is to be considered separately. Furthermore@ this standard applies to buildings and properties with an electrical energy consumption of > 100000 kWh/a@ where it is usually obligatory for energy customers to enter into a contract with a quarter-hourly measurement. In accordance with DIN EN ISO 50001@ this standard supports the steps ??Introduction and implementation??@ ??Monitoring@ measurement@ and analysis?? as well as the non-conformities within the ??Non-conformities@ corrections@ corrective@ and preventive measures??.
