Energy Audit Implementation According to ISO 50002 Standard in a Bakery Company

Abstract

The global warming resulting from the use of fossil fuels is putting pressure on governments to formulate and adopt energy policies aimed at different sectors of the economy. One of the most significant measures in this direction is industrial energy efficiency, a subject that concerns SMEs. An SME was identified in the Valle del Cauca region that recognized the economic and environmental need to have a more efficient system, especially in energy consumption. A bakery company met the requirements, this company has whole wheat bread as its main product. Likewise, during its operating time, an energy performance study has not been carried out, which leads to not knowing if they make adequate use of energy, be it electrical or in the form of heat, which can cause inefficiencies in their processes.Keeping these aspects in mind, in this article an energy audit process was implemented in the bakery company, according to the guidelines of ISO 50002; structuring the stages of the audit process, using a flow diagram; identifying different opportunities for improving energy performance for equipment with higher consumption and therefore greater savings potential; evaluating these improvement opportunities, which are linked to the change of operation and maintenance; and generating recommendations that make it possible to make correct decisions regarding energy consumption and thus reduce costs of this nature.
