From the individual meter to the energy report

Tetrag is a total solution provider with core competence in energy controlling and has over 20 years of experience in the design and technical implementation of systems for the sustainable operation of buildings and facilities.


Targeted. Sustainable. Economical.

We develop complete solutions in the field of energy controlling and also implement them as a general contractor within the specified time frame and at guaranteed costs.

Our service ranges from the individual meter to the finished energy report. Professional energy controlling reduces energy consumption and CO2 emissions. It also shows where action is needed to further increase the efficiency of a building or technical system.

During operation, energy controlling serves as a monitoring tool. It automatically detects deviations and thus allows rapid intervention. We use the e3m energy data management system as a system solution.



Energy monitoring at Implenia's Mannheim works yard Mannheim depot

In an energy monitoring pilot project at the Mannheim site, energy consumption was first scrutinized and then potential energy savings were uncovered. Initial measures have led to a significant reduction in energy costs.


A comprehensive energy concept - from the meter to monitoring and operational optimisation.

We support you in the professional implementation of energy controlling. In doing so, we advise you on various levels, be it in the measurement infrastructure, in the communication to the meters, in the interfaces to operating processes or in the presentation and processing of the data. We tailor our energy monitoring solution to your needs and ensure smooth operation and optimisation of the building technology systems.

We chose Tetrag as our supplier because of its outstanding performance as a general contractor and its great expertise in energy management. Our high expectations were fully met.
