Industrial energy consumption lies between 30% and 70% of the total energy consumed in selected countries. Cement production is one of the most energy intensive industries all around the world. This paper deals with an energy audit analysis in a cement plant in Iran. In all recent works, after performing an energy audit, different strategies are offered to reduce energy losses. Generally, these strategies differ from the viewpoint of economics and their extent of loss reduction, which makes it difficult to choose one of them. In this paper, a decision-making procedure such as an analytic hierarchy process (AHP) after an energy audit process is proposed to help the decision maker in this process.
