Managing Director
Energy Data GmbH
- The energy baseline is a snapshot of energy metrics under given reference conditions. Changes in these conditions can greatly affect performance and must be adjusted for analysis – ISO 50001 calls this normalization.
- A simple example is the weather's effect on heating needs, which is normalized by degree days.
- Some energy data is available immediately and can be integrated into your systems via an interface – from simple Excel files to professional energy management software.
- From introducing an energy management system to energy efficiency measures and technology consulting – as an independent partner, I am here to advise you!

Summary
As an efficiency manager and energy consultant, I reduce your energy costs and help you make a contribution to climate neutrality.
- My motivation: We release 51 billion tons of greenhouse gases into the atmosphere every year, fueling climate change. We must bring that number down to ZERO!
We can't achieve the energy transition just by using renewable energies; we also need to use the energy we produce as efficiently as possible. The cleanest and cheapest kilowatt-hour is the one you save.
The business motivation is to raise margins by cutting costs and to use the contribution to climate neutrality as a marketing measure to stand out from the competition.
My goal: As a neutral and independent consultant, I guide companies and energy managers on the path to an energy-efficient and sustainable organization. From providing energy data to targeted consulting to acting as an energy management officer - I support you professionally and transparently.
Because: Only an efficient company can be a competitive company.
