Practical Example 5 EnergyEnergy management can be defined differently depending on the perspective within a building or a town's network. Inside the building energy management is a method to save final energy costs such as electricity, heat and water.  pdfDownload Energy and Smart Metering PDF

  • A key for effective energy usage inside a building is informing the consumer continually about energy consumption. 
  • KNX Smart metering provides the necessary equipment for this solution.There are KNX devices covering many different elements of energy management. These include:
    • Peak demand monitoring
    • Current detection
    • Network monitoring
    • Load shedding
    • Meters
    • Interface to M-BUS
    • Energy pulse counting
    • Data logging
    • Visualisation
    • Sensors and actuators
    • Controllers and data processing
  • KNX visualisation of energy consumption is useful for the consumer but insufficient to actively ensure energy efficiency within the building. 
  • The KNX devices can give cost information for heating and electrical consumption but more importantly, room temperatures, status of windows, occupancy, active power of circuits and behaviour of electrical consumers can also be monitored. 
  • Better analysis of the user's consumption patterns and saving potentials can be made by the energy manager to achieve maximum savings. 
  • KNX provides solutions for visualisation and automation that can be combined with monitoring of utilities. The result of this approach produces active energy management and visualisation of energy consumption, providing the tools to achieve energy saving actions.
