On the 31st of May 2016 the professional journals TGA, HLK and PUNKTUM arranged the 3rd conference „Energie im Krankenhaus“ in the Eventhotel Pyramide, Wien Vösendorf. EUDT, which ist the developer of the energy management system BLUAUL, was also a part of this conference. We are still pleased with the busy appearance and the large interest in energy future. With an amount of 190 members it was possible to live up to an earlier success. Many people listen to the deeply interesting presentations regarding the long term energy and cost efficiency.
