Energy control

Efficient. Sustainable. Constant.

Professional energy control forms the basis for a continuous energy- and cost-optimisation process and ultimately leads to a reduction in energy consumption and carbon emissions.

Successful energy control helps reduce consumption and carbon emissions. It shows where action should be taken in order to further increase the efficiency of the building or technical facility. During operation, deviations are detected automatically, allowing for quick intervention. 

We provide you with competent advice with regard to the tasks and responsibilities of an energy manager, the level of detail of the measurements or the internal interfaces for systems and processes. 

Our foundation is the e3m system originating from the energy control system Tetrag has been developing since 1998. Since 2010, the products of the OPIT company were successfully distributed worldwide under the name “e3m”.
