Scientists 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.
