Effective management and operation of buildings plays a key role in the life cycle of a building, with a significant part of the costs being represented by the use phase of the building. Facility management uses modern digital tools to manage maintenance, monitor technical equipment and automate operational processes. Digital twins, software platforms such as CAFM and BIM enable more accurate planning and more effective decision-making. Digitalization of building management and maintenance processes brings increased efficiency, data transparency and improved cooperation between all stakeholders. The introduction of digital solutions in building management and maintenance brings a number of benefits, including better control over costs, increased safety and improved user comfort. Digitalization also supports the sustainability of buildings, as it allows for more accurate monitoring of energy consumption and prevention of emergency situations through predictive maintenance. Research in this area therefore focuses on the analysis of available tools and methodologies that enable effective management of buildings in the digital era and bring new possibilities for their long-term and efficient operation.
