About Ralf

As an energy consultant for residential and non-residential buildings, I independently advise clients on possible and sensible renovation options. This includes a comprehensive inventory and advice on the many and often opaque funding opportunities. I support my clients from planning through application to implementation.
My years of experience in dealing with industrial clients, especially automotive OEMs, as well as my experience in managing large projects on a national and international basis, help me with this.
In addition, I have extensive experience in setting up and managing international units.
I find the introduction of new and lean processes and change management very exciting and essential for successful companies. No change, no progress.
I maintain communication that is on an equal footing, honest, and open.
I involve my employees early in decisions.
