Two engineers, Norbert Klammsteiner and Georg Felderer, in 1997 started their activity as freelancers in the energy field. At the beginning, they were both independent workers but already using the name INGENIEURE Felderer & Klammsteiner; they then started using the name Energytech, the combination of which was featured in the company logo until 2007. In 1998, the firm became one of the first five BIC companies (Business Innovation Center) with headquarters in via Negrelli in Bolzano and finally in the current TIS building in via Siemens in the same city. In 2000, the associated studio, INGENIEURE Felderer & Klammsteiner, was founded. In 2003, the firm moved to its current headquarters in via Negrelli in Bolzano. Finally, towards the end of 2006, Energytech s.r.l. was founded, and later became fully operational in 2008.
