Städtische Werke Nürnberg GmbH, N-ERGIE AG

Comprehensive energy efficiency monitoring

N-ERGIE AG has various company sites in Nuremberg and has been using EnEffCo® with more than 500 license data points since 2016.

The Challenge

In its core businesses, Städtische Werke Nürnberg GmbH (StWN) is responsible for the supply of energy and water, public transport and real estate on behalf of the city of Nuremberg. StWN was looking for a software solution to increase the effectiveness of their energy management. A chief requirement was for the software to enable comprehensive energy efficiency controlling, especially at the subsidiary N-ERGIE.

By using EnEffCo® as our energy management software, we were able to repeatedly reduce energy costs and to improve energy efficiency at our sites.“
