The German energy adviser’s network (DEN) is a union of engineers, architects and technicians. The common scope of work connects all members: Conseling and planning achievements for power-saving building activities and modernising of buildings as well as the optimisation of energy efficiency in the trade and in local authority districts.

Since the establishment of the association in 2001/2002, more than 1200 offices joined the network and offer their services all over Germany.

Another common feature is neutrality and independence: members do not receive any commissions or other earmarked payments from manufacturers, craft businesses or retailers for their work. After all, independent advice simply provides greater certainty – and helps people make the right decisions at the right time.
