focusEnergie GmbH & Co. KG


FocusEnergie GmbH & Co. KG is a company based in Freiburg im Breisgau, Germany, that deals with the implementation of efficient energy concepts for the supply of electricity, heating and cooling. The focus is on the installation of climate-friendly and renewable energy generation systems in combination with intelligent storage solutions and e-mobility.

As a general contractor, the company offers commercial and industrial customers all services from a single source, from planning to maintenance, including ancillary trades such as civil engineering, carports, renovations, audits and subsidies.

Electricity and heat can now be produced more cheaply and more independently of energy suppliers. Numerous industrial and commercial enterprises are already using renewable energies to cover their energy requirements. The installed capacity of photovoltaic systems is growing from year to year.

We are convinced that the implementation of efficient energy concepts for the supply of electricity and heat is one of the best investments of all, also in terms of rapid amortization.

We accompany you in the implementation of efficient energy concepts for power and heat supply.


Renewable energy solutions: The combination makes the difference

Our strength lies in the combination of different technologies as a coherent energy concept, which we individualize for each application.

Renewable energy solution for Schwarzwald Eisenhandel Gmbh & Co. KG in Lahr

photovoltaic system, roof, black forest iron, renewable energies

Before Schwarzwald Eisenhandel GmbH & Co. KG from Lahr decided to invest in a future-oriented and independent energy supply, the approx. 800 m² flat roof hall and two production halls were supplied with the conventional mix of purchased electricity and fossil fuels. Previously, the production halls were uninsulated and unheated, the warehouse with office wing was supplied by gas heat with the help of radiators and partly with underfloor heating.

  • Roof renovation: approx. 3000 m²
  • Civil engineering
  • Transformer system 1250 kVA: with inverters
  • 738 kWp PV system: flat roof + gable roof
  • Infrared radiators
  • Electromobility

The first step towards more efficient energy use was the complete renewal of the dilapidated hall roof (3,000 m²) and the installation of a photovoltaic system with 738 kW peak on both the new hall roof and the existing flat roof. focusEnergie implemented extensive electrical work on the grid connection, including civil engineering and the construction of a new transformer station with 1250 kVA. Sufficient reserves were planned for the connection power, since not only will the heat supply be electric in the future, but nothing will stand in the way of a later installation of electric vehicle charging stations (possibly with PV carport). In the future, a heat pump system will take over the heat supply in the storage, exhibition and office rooms, while infrared high-performance radiators in the halls will ensure a pleasant climate at the respective workplaces.

The entire power supply for light, heat and production of the company is now generated by the photovoltaic system including surplus feed into the public grid.

Since an electricity storage system does not yet appear to be economically viable today, green electricity is still purchased from the grid on a pro rata basis.

With these measures, the company Schwarzwald Eisenhandel GmbH is already more than climate-neutral in terms of energy supply, and sector coupling has also been implemented to the extent that it makes sense today. The networked plant components are optimally coordinated with each other and are digitally monitored remotely by focusEnergie.

In the summer of 2022, the plant will be supplemented by a PV carport and charging infrastructure for electromobility.

What the customer says:

"The professional and prudent way of working already in the planning phase, the qualitatively flawless implementation and punctual adherence to deadlines and costs have convinced us very much. Thanks to focusEnergie, our company at the Lahr site has been completely and profitably restructured so that the entire energy supply is now in our own hands. This is a sustainably excellent result, both economically and ecologically."
