17 EN 15232: History, versions; Usability The evolution of the standard followed the request of the mandates 17

18 EN 15232: History, versions; Usability We recomand two neutral documents who describe this standard: 18

19 EN 15232: History, versions; Usability pren and pren (TR) The mandate M/480 asks for: The pren and the TR pren are the result of the BAC Consortia for this Mandate. Other 12 BAC documents (6 standards and 6 TR s belong to EPB standards set). 19

20 EN 15232: History, versions; Usability pren and pren (TR) The standard EN15232 "Energy performance of buildings Impact of Building Automation, Control and Building Management" provides guidance for taking BACS and TBM functions as far as possible into account in the relevant EPB standards of M/480. This standard specifies: A structured list of control, building automation and technical building management functions which have an impact on the energy performance of buildings; A method to define minimum requirements regarding the control, building automation and technical building management functions to be implemented in buildings of different complexities Detailed methods to assess the impact of these functions on the energy performance of 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; A simplified method to get a first estimation of the impact of these functions on the energy performance of typical buildings. 20

21 EN 15232: History, versions; Usability pren and pren (TR) 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. 21

22 EN 15232: History, versions; Usability pren and pren (TR) The evolution also include: a)in Annex A, a detailed calculation procedure has been added; b)a 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 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)an 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 22

23 EN 15232: History, versions; Usability pren and pren (TR) STRUCTURAL ELEMENTS OF THE STANDARD: 23

24 EN 15232: History, versions; Usability pren and pren (TR) The EN standard defines four BAC energy efficiency classes, labeled A to D, that correspond to the level of automation, control, and supervision installed. The definition of each class is based on the presence or absence of a set of automation functions, control, and supervision without regard to the details of their implementation. Class C generally serves as the reference point for comparing efficiencies. As shown graphically EN15232 describes the classes as follows: Class D Non-energy Efficient: corresponds to traditional and technical systems that provide no automation or energy-efficiency Class C Standard: corresponds to standard automation systems and normal controls. Class C is considered the reference class Class B Advanced: corresponds to advanced automation and control systems and some Technical Building Management (TBM) functions for centralized control Class A High Energy Performance: corresponds to systems similar to those of Class B but with levels of accuracy and completeness that ensure high energy performance 24

29 EN 15232: History, versions; Usability pren and pren (TR) Practical example of using the class A for office: 29

30 EN 15232: History, versions; Usability pren and pren (TR) CALCULATING BACS EFFICIENCY: COMPARISON OF THE DETAILED AND BAC-FACTORS METHODS The EN standard presents two different procedures for determining the impact of BACS functions on the energy efficiency of a building: -1)BACS efficiency factor method, also called the simplified method -2) Detailed calculation method The method using BAC efficiency factors provides reasonable estimates based on coefficients calculated from actual measurements that were performed on buildings representing many different types and for rooms with different boundary conditions. It is particularly useful in the initial phases of a project. The BAC factors method allows one to quickly assess the impact on energy consumption of implementing a BACS and provides direct evidence of the economic value of adopting a given level of automation, control, or supervision. It can apply to residential buildings as well as offices, libraries, schools, hospitals, hotels, restaurants, malls, and shops. The detailed calculation method can be applied only with comprehensive information on the building and proposed systems. This method returns a result with higher accuracy, but it requires a much greater depth of knowledge and much greater effort; A SOFTWARE CALCULATION TOOL COULD BE A MUST! 30
