Challenges in adopting energy management systems by Brazilian companies: A fuzzy DEMATEL approach

Abstract

ABSTRACT This paper investigates the relationships between challenges faced by Brazilian companies in adopting Energy Management Systems (EnMS). The fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) methodology is employed to examine the interdependencies between the challenges. The study involves assembling an expert panel to assess the causal relations between key challenges identified through a literature review. The findings reveal that challenges related to insufficient financial resources, deficiencies in competencies within the implementation team, and lack of support from top management are pivotal factors influencing the adoption of EnMS. These challenges are positioned as core factors, highlighting their critical role in EnMS implementation. Conversely, factors such as difficulty in determining appropriate performance indicators and justifying EnMS certification maintenance are categorised as impact factors, signalling their lower priority for resource allocation. The study contributes to research by providing a nuanced understanding of the challenges hindering EnMS adoption and their interdependencies. Additionally, the findings offer practical insights for organisations seeking to implement EnMS, guiding resource allocation and strategic planning efforts to overcome barriers effectively.
