ARTICLE INFO ABSTRACTScientists and researchers have been increasingly studying and seeking alternatives to solve problems related to the power consumption, aiming at environmental conservation and financial savings. In this paper, Smart Energy (SE) is the term used to refer to energy studies in the areas of Smart Grids, Smart Cities, Smart Homes or Buildings. This paper has as a guiding question: how have the scientific studies in Knowledge Engineering and Management (KEM) area contributed to the SE area? The goal of this research is to present a systematic literature review of the scientific research on KEM area in SE context, particularly in thermal heating in Smart Building context, throughout the last 10 years. This systematic literature review, organized in a bibliometric study format uses syntax and content analysis and was conducted in eight stages of research in which were used three known and relevant scientific databases. The present study analyzed 61.662 papers in eight stages. The result was 18 papers strongly related to the scope of this research. The analyses point to a set of researches that mainly use the Elicitation, the Acquisition and the Knowledge Discovery as the most used KEM processes. From the point of view of the use of Information Technology (IT) approaches, it can be highlighted: Machine Learning, Artificial Intelligence algorithms and especially the proposition of their own algorithms.
INTRODUCTIONDue to the high levels of CO 2 emissions and to the growth in power consumption it is becoming increasingly important to carry out scientific studies in order to reduce environmental impacts and to contribute to financial savings of final users. In this sense, some approaches and terminologies have been established in the areas of intelligent power consumption such as Smart Grids (SG), Smart Cities (SC), Smart Homes (SH) and Smart Buildings (SB).The term SG is related to the use of Information Technology applied to the management and operation of electrical networks. The term SC has many applications. One of them, in particular, it is the study of consumption and production of sustainable electricity. Finally, SH and SB have the same bias, although being distinct terms, both refer to the study of smart environments such as buildings or houses. The term "smart" is commonly used to equally describe the use of technological innovation and ITs for automation purposes and resource savings, Lund et al. (2012). Such areas of study have many points of convergence. In this study the term Smart Energy (SE), Preissler Junior (2015) is used to refer to research and development initiatives in the cited areas of study. Here, however, the terms are applied to research focusing on energy context. Furthermore, the Knowledge Engineering and Management is an interdisciplinary field which over the past 25 years has been using IT as a tool to "operationalize" the Knowledge Management (KM), Nonaka (2008), Rus and Lindvall (2002). Assuming that the term "smart" is related to the use of IT and considering that IT ...
