Abstract This article presents the application of an expert system (ES) prototype as an intelligent tool for preliminary diagnostics of energy efficiency (EE) potential in Brazilian industrial plants and knowledge management (KM) in organizational environments, aimed especially to small- and medium-sized enterprises. The prototype provides the diagnostics rationale through a module for an explanation to support the decision making and provide insights regarding the adoption of EE actions. The knowledge base required by the prototype is built from the expertise and experience of a group of experts in EE and professionals from the industrial sector. The knowledge acquired from this interaction is represented in the form of rules, which are computationally implemented through a well-known tool for developing ES. Then, the resulting prototype is validated by the same group of multidisciplinary experts. Two different applications are presented to demonstrate the possibilities of EE improvement in industrial plants. These applications also show the ES as a valuable resource for organizational KM. In such a context, the ES creates a permanent corporate memory regarding EE, so that the access to this knowledge is independent on the availability of the human experts in the area. The ES also turns EE expertise into lasting value through sharing and retention actions, contributing to further improvements and processes continuity.

1 Introduction Although Brazil stands out as a country that concentrates most of its power generation from renewable sources, the current supply situation in the electric sector is worrisome. This is mainly due to the serious consequences related to the energy rationing that took place in 2001 and the great drought of 2015, which resulted in long periods of thermoelectric Technical Editor: Monica Carvalho. * Gilberto Paschoal Buccieri [email protected] * José Alexandre Matelli [email protected] José Antonio Perrella Balestieri [email protected] 1

generation. From this new perspective, concerns about costs, preservation of the environment, sustainable development and the efficient use of energy (electric, in particular) became the subject of discussions and studies in the industry, seeking alternatives that enable energy-saving without production loss or to the appropriate conditions for the operation of the installations. Besides investments
