Impact of building automation control systems and technical building management systems on the energy performance class of residential buildings: An Italian case study

The paper focuses on the evaluation of the impact on residential buildings of building automation control (BAC) and technical building management (TBM) systems. This work shows how the control, monitoring and automation functions considered by the European Standard EN 15232 can considerably influence the energy performance of a single-family test house and, consequently, its energy performance class. The study puts into evidence that the benefit that can be drawn from the installation of BAC and TBM systems depends on the type of technical appliances in the household and on the starting energy performance class. Finally, the economic impact due to the introduction of BACS or TBM function is evaluated for different starting energy classes of the household under consideration.
