Project manager competencies have been widely discussed in the literature. Although many works present lists of competencies for project managers, specific competencies for smart buildings were not found. This work aimed to identify the main competencies of project managers for the management of smart building projects. The methodology consisted of a two-step approach using the guidelines of preferred reporting items for systematic reviews and meta-analysis (PRISMA) to perform broad and detailed bibliographic research. Initially, a literature review was carried out to identify the main research fields related to the management of smart building projects and the specificities of these fields that can influence the management of this type of project. Next, these specificities were related to the competencies of project managers mentioned in the literature, to identify a set of more relevant competencies for project managers of smart building projects. The results showed that the main research fields are related to scope, risks, costs, schedule, technologies and systems, sustainability, and general characterization, which consider objectives, barriers, challenges, and regulations. They also showed that the most relevant competencies for managing smart buildings projects are technical competencies, leadership, communication, budgeting, attitudes toward risk, strategic management, organization, and specifying real requirements. These findings show the importance of hard and soft skills for managing smart building projects.
