BMS (Building Management System), i.e. the central building control, assumes integrated control of all building functions-from air conditioning and heating to lighting, access control and security issues. Properly designed BMS solutions improve the operation of the building service, allow for a quick reaction in case of emergency situations and significantly facilitate maintenance activities. Building automation systems also allow for data collection and analysis, which can be used among other things, to optimise energy and water consumption in buildings. The aim of the paper is to provide and to discuss findings of the analysis of the impact of the BMS application in the city stadium design, which is an example of a public facility, on the possibility of controlling the life cycle costs of the facility under examination. In the first step, on the basis of the design documentation and the stadium operation schedule prepared by the authors, the life cycle costs of the analysed facility were calculated in accordance with the methodology recommended by the Polish public procurement law with use of the SMART SPP calculation tool. The functional assumptions of the BMS designed for the stadium were taken into account. Then a change was introduced to the analysis at the input consisting in the simulation of BMS removal from the facility and then the introduction of the risk factor of human error on the part of the staff during the annual operation of the stadium in relation to the operation of the lighting system of the facility. The analysis is summarised by comparing the calculation results for both scenarios. The findings indicate the benefits of using BMS in facility management.
