“…Moreover, the definition of suitable performance indicators is a basic requirement for an ICT enabled management of energy efficiency. In [28] a selection of energy efficiency KPIs can be found, which are implemented in manufacturing companies, especially in the energy-intensive industries. Two typical indicators are the energy intensity (EI) and the specific energy consumption (SEC).…”

Abstract. Climate change and unsecured energy supply are topics that become increasingly important in today's society. Although renewable energy technologies may be a long-term solution, more efficient energy use potentially makes a high and economic contribution to the given challenges in the short term. New CO 2 regulations, rising energy prices and environmentally aware customers make energy efficient manufacturing a priority topic on the agenda of industrial companies. This paper focuses on drives for industrial companies to become more energy efficient in their manufacturing processes by integrating energy efficiency performance information and communication technology (ICT) in production management systems. Based on an EU roadmapping project, the paper analyzes which management tools and concepts support manufacturing companies to successfully implement energy efficiency improvement measures. By integrating energy efficiency performance criteria in ICT systems, decision-makers in industrial companies will be supplied with real-time and accurate information enabling them to make more effective business decisions.

“…In their study conducted among the largest corporations in Sweden, Sandahl and Sjögren (2002) showed that PB is the most commonly applied capital budgeting tool in all types of industries, but is also the most frequently used in the engineering sector (90% of the studied firms stated they used the PB method). The PB method is also a commonly applied tool for the evaluation of energy efficiency investments (e.g., Harris et al, 2000;Sandberg and Söderström, 2003;Bunse et al, 2009). However, firms, in particular larger firms, occasionally complement their evaluation methods with NPV and IRR, for instance (Sandahl and Sjögren, 2003).…”

The Non-Energy Benefits of Industrial Energy Efficiency : Investments and Measures

Improved industrial energy efficiency is viewed as an important means in the reduction of CO2 emissions and climate change mitigation. Various energy efficiency measures for improving energy efficiency exists, but even evaluated as cost-effective, there seems to be a difference between the energy efficiency measures that theoretically could be undertaken and which measures that actually are realised. On the other hand, industrial energy efficiency measures might yield extra effects, denoted as non-energy benefits, beyond the actual energy savings or energy cost savings.Based on interviews and a questionnaire, results showed that the Swedish industrial firms studied had observed various non-energy benefits. However, few of the non-energy benefits observed were translated into monetary values and included in investment calculations. Results indicated that this non-inclusion could be explained by lack on information on how to measure and monetise the benefits, but even if not translated into monetary values, some of the non-energy benefits were sometimes used qualitatively in investment decisions. The utilisation of the benefits seemed to depend on the type and the level of quantifiability among the perceived benefits.This thesis has also explored energy efficiency measures and non-energy benefits for a specific industrial energy-using process -compressed air. A literature review on energy efficiency in relation to compressed air systems revealed a large variation in which measures that could be undertaken to improve energy efficiency. However, few publications applied a comprehensive perspective including the entire compressed air system. Few non-energy benefits of specific energy efficiency measures for compressed air systems were identified, but the study provided insights into how non-energy benefits should be studied. This thesis suggests that energy efficiency and non-energy benefits in compressed air systems should be studied on specific measure level to enable the observation of their effects. However, the studies also addressed the importance of having a systems perspective; the whole system should be regarded to understand the effects of energy efficiency measures and related non-energy benefits. Till Tjalle AcknowledgementsFirst, I wish to thank my supervisor, Patrik Thollander. Thanks for your guidance, support and never-ending stream of ideas. With only a few weeks to go before the end of my previous job, you encouraged me to submit an abstract for a conference that threw me directly into the field of energy efficiency and non-energy benefits. This served as a quick and stimulating start to my PhD studies, and I thank you! Thank you to Josefine Rasmussen for very good collaboration throughout the project on non-energy benefits, especially when working on supertvåan (Paper II) and conducting interviews together! I really enjoyed working with you and I miss our discussions during our road trips.I would also like to thank my co-supervisor, Mats Söderström, and the rest of the nonenergy benefits pr...

“…Monitoring and simulation are seen as essential elements of energy management [1]. Key Performance Indicators (KPIs) are developed to evaluate if changes in the process for increasing energy efficiency have a verifiable benefit [13]. Their monitoring supports assessment of optimization potentials and visualization of benefits from improvement measures.…”

Global environmental challenges lead to a rising importance of resource efficiency in industry. The strong environmental impact of manufacturing processes necessitates a significant reduction of the amount of employed resources. Therefore, the potential of production planning and control (PPC) systems is analyzed from a top-down and bottom-up perspective in terms of increasing the energy efficiency of manufacturing processes. A conceptual approach is developed to embed energy efficiency in a PPC-logic in order to link managerial targets with machine tools located on the shop-floor.
