icon WaterWatt case studies report
Case studies were performed with selected representative IWCs. Their units were characterised, specific energy consumption was measured and measures for the improvement of energy efficiency were developed. For reasons of comparability, specific energy consumption per pumped m3 was taken as the main benchmark. Furthermore, regional factors and sociological boundary conditions for circuit operation were studied and transferability of the specific energy consumption and improvement measures to other circuits was evaluated.

Public Deliverables

In this section you can find all public deliverables, which are already approved by the European Commission.

WP 1 – Study of Energy Consumption in Industrial Water Circuits

icon List of representative industrial water circuits (D1.1)
In the frame of 10 case studies in the water intensive industrial branches of metal, chemical, paper, food and ceramic industry representative circuits were identified.
275 KB
icon Catalogue of representative industrial water circuits and their units with specific energy consumption (D1.3)
In the frame of case studies representative circuits and their units were examined in detail. The results were documented in questionnaires (D1.2). The main circuit units were pumps, cooling towers, gravel filters, sedimentation tanks and gas scrubbers. The main electricity consumers were pumps and cooling tower ventilators. The data of these units were derived from the questionnaires to calculate specific energy consumption values. These values can be used for benchmarks definition. This deliverable (D1.3) provides joint basis for further studies in WP2.

WP 2 – Modelling and Optimization of Industrial Water Circuits

icon Report with the description of the methodology used to modelling the typical water circuits. (D2.1)
The specific objectives of Task 2.1. is to provide generic models of each component of the ten selected case study circuits in WP1. This report gives an overview of the process of producing the physical models that simulates the industrial water circuits from the WaterWatt case studies. The report explains the methodology followed and the choices taken through the process of producing the WaterWatt models.

icon Report with the identification of the KPI’s for typical water circuits (D2.2)
In this deliverable the Key Performance Indicators (KPI’s) are specified for each component and industrial water case study circuit. The KPIs correspond to indicators that translate the energy performance of the components by itself and of the overall circuits. From these indicators it will be possible to understand if the component/system is running efficiently in terms of energy.

icon Report with the description of the methodology used to prioritize the energy efficiency and identification of the prioritized measures for the selected case studies (D2.4)
In general, the improvement of energy efficiency in water circuits can be reached by:
  • Reduction of water consumption in the production process,
  • Dynamic adjustment of the circuit operation to the production process,
  • Reduction of pressure demand and pressure losses in water circuits and
  • Improvement of energy efficiency of pumps and cooling towers.
Improvement measures can be evaluated and prioritised according to the following technical, economic and environmental objectives, like improvement of production process reliability (avoidance of downtime; maintaining of required flow, pressure and temperature), cost reduction, as well as energy saving and reduction of CO2 impact.

WP 3 – Human and Organisational Challenges

icon Report on analysis of regulatory frameworks for energy efficiency/environmental sustainability (D3.1)
The main objective of this report is to understand the behaviour of organisations in relation to energy efficiency imperatives and environmental regulation within the participating member states (France, Germany, Italy, Norway, Portugal, United Kingdom). Other objective was to scale concrete practices in the member state concerning energy consumption in relation to the sector and national and supranational regulation. This involved analysis of relevant legislative and institutional frameworks, and auscultation to relevant stakeholders.

icon Report on energy management structure and behaviour and motivation analysis within each sector (D3.2)
The aim of conducting case studies was to understand how industrial water circuits work in practice and in particular contexts. From the technical perspective, the case study approach has been important for incorporating the modelling of water circuits into the E3< Platform. From the sociological perspective, the case study approach has proved to be an excellent method to develop the understanding of the organizational dimensions of achieving greater energy efficiency.The following sets of case studies have been conducted:
  • A steelwork in Germany
  • A steel plant and a non-ferrous metal plant in Norway
  • A paper & cardboard and a sugar plant in Portugal
  • A steel plant in the United Kingdom

icon Report on organisational indicators by sector (D3.3)
This report summarises the findings of the sociological research on the human and organisational challenges i.e. research on the social, institutional and structural challenges faced by companies wanting to increase the energy efficiency of their industrial wa- ter circuits. The report identifies a range of organisational and contextual factors based on the case studies conducted at different plants within a range of sectors.

WP 4 – Energy Efficiency Evaluation (E3) Platform for self-assessment

icon Report on concept, use cases and requirements definition (D4.1)
This document presents the concept, the use cases and the requirements definition for the WaterWatt E3 Platform. It provides an overview of the E3 Platform concept and its tools, such as decision guidance matrix, energy efficiency database, water circuit simulation software, e-learning and forum. Some significant usage scenarios are described, in order to show how users can interact with the E3 Platform, and summarizes the list of requirements produced. Furthermore, this report outlines the use cases collected, providing information for each use case like: actors of the use case; goal to reach; any preconditions; trigger of the use case; any post-conditions; steps to follow.
