Prague councillors sanctified “Multiutility measuring in The Capital City of Prague rented flats” final report, in short, presented under the title “Digital Energy Measuring”. Full endreport with detailed information about the project’s completion and gathered findings within its pilot run realization is thus available for those whom it may concern here.

The project in which the city company Operator ICT, Plc. (OICT), Prague City Hall and company PREmereni, Plc. participated offered in selected apartment block owned by The Capital City of Prague a new multiutility measuring system which secured a complete remote energy reading of all energies (heat, electricity, gas, cold and hot water) and measured figures displayed synoptically in a web application to tenants.

“Tenants we able, base on the consumption overview, adjust their consumer behaviour and follow in real-time via the application how for instance switching off lights or heat regulation in a room impacted energy consumption decrease. Another goal was to verify wireless technologies functionality in a historical building,” stated OICT General Manager Michal Fišer. Web portal for the project purpose was provided free of charge by the company PREmereni.

Within the pilot project scope, 294 measuring devices with remote energy reading were installed in flats and commercial premises of Vrtbovský Palace. From that 36 were invoicing gas meters, 46 cold water meters, 23 hot service water meter, 1 main invoicing water meter, 4 invoicing gas meters and 184 heating costs indicators. All sensors were connected employing 14 access gates into a joint network based on Wireless M-BUS technology. Data were subsequently sent via GSM network to a server, validated there, stored and visualized by the web application.

“The frequency of data being sent was defined according to energy type in case of electricity to every 15 minutes, in case of gas and water once per hour and in case of heat once per 24 hours. Reliability of the meters during data sending was 84.8% during the whole project. Even residual data were not lost, meter merely sent it in the following reading. Gained data serve as sources for itemization purposes to energies by the estate administrator for respective clients,” filled in OICT’s Deputy Chairman and Project Management and Funds Section Director Matej Šandor. According to his words, all components were bought into OICT possessions owing to the following operation and data providing to the estate administrator. Lifetime period of the whole technology is five years at least.
