Increase energy efficiency - reducing energy costs

Has your energy supply grown steadily and been getting old?
Then it is very likely that you spend more on energy costs and maintenance / servicing than necessary.

In contrast to short-term efficiency measures, it is above all the long-term choices made in the energy production that are decisive for the competitiveness of your business.

For the generation of electricity, heat, cold, steam, etc., there are a variety of techniques or technology combinations. Once made decisions influence the conditions of your energy supply and thus your energy costs for a long time.

Is an energy consultancy worthwhile?

Definitely yes. Due to our long-standing advisers’ history we can guarantee that we will detect energy saving potentials in your company, too. We have advised more than 1,000 clients, who were able to achieve average savings of 5 % to 6 %. Individual measures even reached savings of over 50 %.

Where are your weak spots?

Often it looks different with the energetic infrastructure. The premise here is usually that the required amounts of energy must be made available safely. Although approaches to energy optimization are often in place, mostly the technical staff does not have the time to work out these ideas for decision-makers.

Increasing energy efficiency – this is how we proceed:

  • Current state analysis

The first step of your project involves a detailed walkabout through your premises by our specialists.  Hereby, the main energy consumers are investigated, and information is collected for in-depth processing of the task.

  • Development of measures

Based on the current state analysis, measures are defined for a more efficient use of energy. Apart from a detailed description of the measures, the necessary steps for their implementation are specified.

  • Efficiency analyses

Possible savings are quantified, and the expected costs for their realization are determined. The resulting measures are summarized in a catalogue of measures and listed according to priority.

  • Overall concept

Based on the individual measures, an intelligent overall concept is developed, which covers energy production and usage across all areas and types of energy, taking into account possible synergies and/or retroactive effects.

„We found energy saving potentials in every company we investigated. Practically every time, they are located in the energy infrastructure and in energy usage.“

Selected projects

We have created energy concepts for these companies and thus achieved significant savings.

Interquell GmbH

Interquell - Energy consulting Großaitingen Wehringen

The realization of innovative steam generation with combined heat and power production consisting of a conventional steam boiler with micro gas turbine and GTA burner (gas turbine exhaust gas burner), renewal of the steam distribution with clean steam generators and a new ventilation system for the supply of high-hygiene areas were able to reduce the ​CO2 emissions by almost 20 %.

​MAN Truck and Bus Germany and Austria​

Energy consulting MAN München

​​The project identified opportunities for saving energy amounting to 13.5 million euros per year. These range from pure organizational measures to larger investment measures such as the realization of a natural gas CHP.


MAN Türkiye A.S. - Ankara

MAN Türkiye - Energy consulting Turkey Ankara

The project identified opportunities for energy savings of around € 300,000 a year. Especially mentioned should be measures such as the energy optimization of the boiler house. By implementing the proposed measures (multi-boiler control, boiler warming, hydraulic balancing, etc.) considerable savings could be achieved.

Stahlgruber GmbH - Sulzbach-Rosenberg

BHKW - Blockheizkraftwerke -Stahlgruber - Energy consulting Sulzbach-Rosenberg

A concept has been developed that provides a reduction in the heat input through the roof windows, improvements to the air curtains and a higher cooling capacity. The heat supply is most economically by a central generation with combined heat and power. The additional costs paid off against the separate supply in 4.3 years.

SRH Wald-Klinikum Gera

Wald-Klinikum Gera - Energieberatung Gera

Among other things, the investigation has identified the following interesting approaches to reduce energy costs: By using a natural gas CHP, it is possible to reduce the heat production costs. The two cooling networks should be hydraulically connected in order to be able to use mainly the more effective chiller for refrigeration.
