The building systems are being projected in the improvement of the efficiency of the total energy consumption and the integration of renewable energies. However, buildings have become increasingly complex because they integrate different types of local energy generation, distribution, consumption, and storage elements. That is why energy management is considered an optimization problem. Therefore, the objective of this review work was to establish a scientific map of building energy management systems (BEMS) and to identify the scientific production that identifies future research projections. In this sense, the bibliometric review methodology was used to quantify the performance, quality, and impact of the research field. The scientific mapping approach analyzes the co-occurrence of terms through clustering techniques and performance analysis to detect and visualize conceptual subdomains of BEMS. The results show five thematic areas in two evaluated periods: Wireless sensor networks (WSN) and office buildings as leading themes in the period 2000 – 2015. While photovoltaic systems (PVS) and internet of things (IoT) are identified as the important issues for the period 2016 – 2022. The most challenging issues of the BEMS is to maximize energy efficiency by minimizing energy losses and consumption. These concepts have given rise to the IoT, which is shown as a motor theme in the strategic map of bibliometric analysis. However, the thematic concept of the Internet of Energy (IoE) in energy monitoring and control in buildings through bidirectional communication between the smart grid and BEMS is appreciated. Therefore, this review highlights IoT and IoE-based BEMS power management as key technologies to support future advanced BEMS implementation. [ABSTRACT FROM AUTHOR]
