Workshop “introduction of energy management according to DIN ISO 50001 for industrial & commercial” within the framework of the 4th RENEXPO Austria 2012 the need to take measures to increase energy efficiency, many companies have already recognised. Often, the required criteria of profitability but slowing down many approaches to energy and cost savings. An Energiemanagementsys-tem is a suitable instrument to optimize the use of energy in a company by purchasing energy eco nomical and eco to energy consumption. The workshop “introduction of energy management according to DIN ISO 50001 for industrial & commercial-be” on the 30.11.2012 in the framework of the 4th RENEXPO Austria, from 29.11 until 01.12.2012 in the exhibition and Congress Centre Salzburg instead – finds, shows how effective energy management in the enterprise can be introduced.
