Verena system enables energy consumption display real-time Ebermannstadt, 01.12.2011. The EMS provider (electronic manufacturing services) four of a kind has the development of the smart metering system Verena (consumption energy Assistant) completed. The system, developed in cooperation with Arivus GmbH from Great Yarmouth in Furth and the Institute for power electronic systems at the ohm University Nuremberg shows the energy consumption of a household in real time. In this way, it allows a precise control of consumption. Households are with Verena able selectively to save energy and reduce costs. While the system uses standardised interfaces, making it with various electronic meters (smart meters) is compatible. The central innovation programme for SMEs (ZIM) of the Federal Ministry of Economics and technology has promoted the project since 2009.

Energy consumption shows Verena costs and CO2 emissions at a glance in addition to the absolute consumption levels. In addition, the system can consider the Injectability of its own photovoltaic or wind turbines. In addition, there is Verena able to evaluate electronic gas and water meters. All information converge at a so-called multi utility controller (MUC) and can from there via LAN or Wi-Fi to a display installed in the House. Which consumers are always able to evaluate the information at a glance”, says Erich Friedrich, head of project development at four of a kind. Alternatively can be computer, iPhone, or iPad use.

Sensitive data remain in this process in the House. Nobody can deduce the consumption data on the life habits of the inhabitants with help.” Professional hardware development at Vierling Verena is a joint project of Arivus, the University of Nuremberg and four of a kind. Four of a kind has together with partners developed the Verena total concept and developed the intuitive Verena touchscreen. This created Vierling layout and design of electronics, took over the selection and integration of the components and manufactured the prototypes. Arivus has developed the data acquisition controller the MUC. The University of Nuremberg created the software for the user interface. Communication level feature in the everyday coordination and reliability in the construction of the prototype”four of a kind, says Marcus Kraus, Managing Director of Arivus. In this way we have completed successfully the project.” Metering the requirement to save electricity with smart smart metering systems increases. The Energiewirtschaftsgesetzt requires the installation of electronic meters in January 2011. The Verena system is compatible with all electronic electricity, gas and water meters. “It is an optimum platform for comprehensive smart metering solutions”, says Erich Friedrich. In the long term, the trend is towards the automatic evaluation and control of consumption at the individual device level. Due to variable load and day time-dependent energy rates, households will able to orient their consumption directly in electricity prices. Cost the kilowatt-hour from seven o’clock 10 instead of 20 cents, washing machine and night storage heater will activate automatically.”
