The state-owned Gewobag is announcing an innovation prize for the first time and is seeking external solutions for energy data management. Applications are possible from January 2nd onwards, with winners receiving a joint pilot project with the housing corporation. This step shows: Berlin's largest municipal landlord is relying on external expertise rather than in-house development when it comes to digitalization. The background is rising ancillary costs and tightened climate targets, which require more efficient energy management in existing properties.
