Inside Out

This study empirically investigates the involvement of actors in the process of energy-efficiency improvements in operations to align strategic sustainability goals across and within operations. The study analyzes development efforts stemming from actors’ decisions and actions that contribute to the process of energy efficiency improvements using semi-structured interviews and secondary information. Data is analyzed using thematic coding. The study deepens the understanding of how firms undertake the transition towards integrating strategic goals for energy efficiency into operations by strategizing for energy efficiency improvements through actors’ involvement. By exploring actors at both strategic and operational levels, and their decisions and actions, the study includes examples of different approaches, namely, top-down vs. bottom-up and inside-out vs. outside-in, thereby conceptualizing the process of energy-efficiency improvements in terms of a framework that outlines the entities of this process. The study further provides an integrative framework for the development efforts by different actors and presents propositions for incorporating energy-efficiency improvements in daily strategic and operational decisions and actions instead of regarding it as a separate or an add-on process.

Alternative Solutions

The cement industry is highly energy-intensive, consuming approximately 7% of global industrial energy consumption each year. Improving production technology is a good strategy to reduce the energy needs of a cement plant. The market offers a wide variety of alternative solutions; besides, the literature already provides reviews of opportunities to improve energy efficiency in a cement plant. However, the technology is constantly developing, so the available alternatives may change within a few years. To keep the knowledge updated, investigating the current attractiveness of each solution is pivotal to analyze real companies. This article aims at describing the recent application in the Italian cement industry and the future perspectives of technologies. A sample of plant was investigated through the analysis of mandatory energy audit considering the type of interventions they have recently implemented, or they intend to implement. The outcome is a descriptive analysis, useful for companies willing to improve their sustainability. Results prove that solutions to reduce the energy consumption of auxiliary systems such as compressors, engines, and pumps are currently the most attractive opportunities. Moreover, the results prove that consulting sector experts enables the collection of updated ideas for improving technologies, thus giving valuable inputs to the scientific research.

Purpose – Energy use in urban areas has turned a subject of local and worldwide interest over the last few years, especially emphasized by the correlated greenhouse gases emissions. The purpose of this paper is to analyse the overall energy efficiency potential and emissions resulting from integrated solutions in urban energy planning, in the scale of districts and neighbourhoods in Brazil. Design/methodology/approach – The approach is based on the description and the application of a method to analyse energy performance of urban areas and support their planning. It is a quantitative bottom-up method and involves urban morphology, urban mobility, buildings and energy supply systems. Procedures are applied to the case study of Agua Branca urban development area, located in Sao Paulo, Brazil. Findings – In the case of Agua Branca area, energy efficiency measures in buildings have shown to be very important mostly for the buildings economies themselves. For the area as a whole, strategies in promoting public transport are more effective in terms of energy efficiency and also to decrease pollutant emissions. Originality/value – Literature review has shown there is a lack of approaches and procedures able to support urban energy planning at a community scale. The bottom-up method presented in this paper integrates a plenty of disaggregated and multisectoral parameters at the same stage in urban planning and shows that is possible to identify the most promising actions by building overall performance indexes.
