The understanding of the organizational aspects of achieving increased energy efficiency in In-dustrial Water Circuits (IWC) over the course of the WaterWatt project has benefitted from two parallel processes. On the one hand, conducting case studies in a variety of countries and sec-tors has helped to identify and to distinguish what might be referred to as ‘universal’ and ‘local’ factors that influence the degree of energy efficiency in IWC. On the other hand, discussions within the WaterWatt consortium, partly informed by insights established during the case study research, about the direction and focus of the organizational aspects of the project have moved forward. The aim of conducting the case studies as part of WaterWatt Project is to understand how indus-trial water circuits work in practice and in particular contexts. For our technical colleagues, the case study approach has been important to help them in their efforts to incorporate the modelling of water circuits into the E3 Platform. From our sociological perspective, the case study ap-proach has proved to be an excellent method to develop our understanding of the organizational dimensions of achieving greater energy efficiency. The case studies have helped us to formulate organizational factors, as well as produce a list of relevant contextual factors, which essentially represent the conclusions of this work (see D3.3). The following sets of case studies have been conducted - A steelwork in Germany in June 2016 - A steel plant and a non-ferrous metal plant in Norway in October 2016 - A paper & cardboard and a sugar plant in Portugal in November 2016 - A steel plant in the United Kingdom in May 201
