Efficient energy management

Save up to 50% on your energy costs

Rising costs for raw materials, resources and energy, increasing competitive pressure in the industries and the current energy policy: all these are factors that demand a rethink in society and the efficient use of energy. About 40% of the total energy in Germany is used to operate buildings. This means that every company also has an economic interest in reducing energy costs through the efficient use of energy. With DEOS energy management, enormous savings potential can be realised in any type of building.

What is DIN EN ISO 50001?

DIN EN ISO 50001 is the first energy management standard adopted worldwide. As a manufacturing company, an energy management system certified according to DIN EN ISO 50001 can qualify you for exemptions from the Renewable Energies Act levy and also reduce your electricity and energy taxes. Our OPENenergy energy management software provides you with essential support in implementing this standard. What’s more, it gives you total control in successfully optimising the energy use in your company, while automatically benefiting from higher energy efficiency in your company buildings.

Convenient energy savings

With us you don’t have to do without anything!

Savings on the one hand are usually associated with sacrifice on the other. But thanks to our intelligent energy management, there is another way! In order to prevent energy wastage, the innovative DEOS control system saves energy where it is not currently needed – “because the best energy is the one that is not consumed“. Consumption in the building is also optimised and controlled more efficiently in order to significantly reduce energy requirements for heating, ventilation and lighting. These two aspects provide enormous savings potential and at the same time a comfortable climate thanks to DEOS’s patented ventilation control system.

Energy data always in view

OPENenergy brings transparency

The energy management software OPENenergy is used as a central tool for the recording, evaluation and monitoring of your energy data. The comprehensive software solution visualises the energy flows in your building and provides you with a precise overview of your consumption in clear graphics. This allows you to reduce your costs to a minimum while maintaining the same level of comfort. For single buildings as well as for globally networked properties.
