The Chodov and Cerny Most shopping malls belong among Prague's largest malls. Chodov with its 300 shops covers more than 100,000 square meters of retail space.

Such large buildings require an advanced system for controlling their energy consumption. That's why AVE, a smart metering system, was installed at these shopping malls. Some energy meters are read automatically by AVE once an hour while the rest of the energy meters are read twice a day. There are 1,458 meters in total. 95 % of them are read via the M-Bus protocol automatically with 99% success. The remaining 5 % of the meters are read manually once a month.
