e3m is an Energy Efficiency Management solution (EnMS) that helps companies optimize, monitor and reduce their energy consumption. It is a software and hardware solution that allows monitoring all types of energy production and consumption. The most common energy sources are electricity and water, but it can also be gases, fuels, water, steam or special gases in some manufacturing processes or hospitals.

e3m is a big data application with the ability to manage millions of records and perform complex data reconciliations for a building, for example, between the different energy consumption values, CO2 emissions (product carbon footprint), occupancy and meteorological data.
