DIN EN 15232:2012-09

This European Standard was created to establish conventions and methods for estimation of the impact of building automation and control systems (BACS) and technical building management (TBM) on energy performance and energy use in buildings. This European Standard specifies: - a structured list of Building Automation and Control System (BACS) and Technical Building Management (TBM) functions which have an impact on the energy performance of buildings; - a method to define minimum requirements regarding BACS and TBM functions to be implemented in buildings of different complexities; - a factor based method to get a first estimation of the impact of these functions on typical buildings; - detailed methods to assess the impact of these functions on a given building. These methods enable to introduce the impact of these functions in the calculations of energy performance ratings and indicators calculated by the relevant standards. This European Standard is defined for: - building owners, architects or engineers, defining the functions to be implemented for a given new building or for the renovation of an existing building; - public authorities, defining minimum requirements for BACS and TBM functions for new buildings as well as for renovation, as defined in the relevant standard; - public authorities, defining inspection procedures of technical systems as well as inspectors applying these procedures to check if the level of BACS and TBM functions implemented is appropriate; - public authorities, defining calculation methods which take into account the impact of BACS and TBM functions on the energy performance of buildings as well as software developers implementing these calculation methods and designers using them; - designers, checking that the impact of all BACS and TBM functions are taken into account when assessing the energy performance of a building. This European Standard should be used for existing buildings and for design of new or renovated buildings. This standard differs from DIN EN 15232:2007-11 as follows: a) in Annex A, a detailed calculation procedure has been added; b) table and calculation procedures have been extended, efficiency factors for the assessment of control functions in domestic hot water control have been added; moreover all efficiency factors have been broken down into heating/cooling energy (formerly thermal energy in general), electric auxiliary energy for lighting and other auxiliary energies (for example, drives). Formerly only the electric auxiliary energy in general had been assessed; c) a new Annex E (informative) "Applying BACS for EMS" specified in EN 16001 has been added; d) a new Annex F (informative) "Maintain BACS energy efficiency" has been added; e) a new Annex G (informative) "Control accuracy" has been added; f) additional information has been given for reasons of clarity, for example, boundary conditions for the determination of the factors or the impact of climatic/geographical conditions. The committee responsible for the German version is Working Committee NA 041-05-03 AA "Energieeffizienz in Gebäuden - Auswirkungen der Gebäudeautomation und des Gebäudemanagements" ("Energy efficiency of buildings - Impact of building automation and building management") of the Heating and Ventilation Technology Standards Committee (NHRS) at DIN, the German Institute for Standardization e.
