This paper presents a real case implementation of a proportional integral derivative controller (PID) into a building energy management system (BEMS). The case study building was done in the ICPE Office Building located in București, Romania. The goal of the implementation was to improve the indoor comfort level and maximize the energy efficiency of the heating system of the building. The algorithms developed are based on a series of chained PID control loops that manage the modularity of different heating system components. Also a parallel PID control loop was developed to further improve energy savings in the south area of the building. With the implementation of all PID’s control loop the heating system has an increased efficiency based on modulating the heating source from district heating system (DHS) and modulating the heating distribution into the building. The results show that energy efficiency is capable even with maintaining the indoor set point temperature and comfort level.
