A major German telecommunications provider was already supplying 100% of the electricity needs for its
administration facilities with renewable energy. Our task was to help them further reduce their energy
consumption while at the same time drastically lowering their CO2 emissions. Our success is clearly visible
in the yearly savings that we managed to generate for them.

A large German automobile producer with multiple production facilities throughout Germany operates a many older ventilation systems, which were in desperate need of being optimized for energy efficiency. The challenge in this case, was that the retrofit work had to for the most part take place during ongoing production in the factories, as demand for new cars simply did not allow for production downtime.

geff Modules applied in this project

This university hospital treats approximately 700.000 patients each year. Its primary focus is oncology.
Energy efficient ventilation equipment is helping them save an average of 4.012.080 kWh of energy per year.

This medical center includes a medical clinic, ambulatory practice, ambulatory rehabilitation unit, and senior living facilities. The multifunctional nature and high patient traffic that this facility deals with on a regular basis present many challenges. Nonetheless, geff was able to help significantly reduce their energy costs.

A manufacturer of industrial equipment and robots requested an energy savings analysis for the lighting in one of its production halls as part of the company‘s internal corporate energy savings program. The results of the analysis showed that the existing high-bay lighting in the hall was giving off much less light than the latest new lighting technologies, even though they use the same amount of energy.
geff‘s solution was an intelligent LED high-bay luminaire system with built-in occupancy and daylight sensors and dimmers, which could be mounted on the existing fixtures (at a height of 8 meters) and offered an anti-glare technology with guaranteed maximum energy efficiency at extremely high light output. Additionally, the client is able to monitor and custom-adjust each individual luminaire via a very simple software solution, leading to further savings through the automatic reduction of lighting hours based on occupancy and daylight.
