NOTE 1 The terms and definitions listed in this standard but defined by other relevant ISO/IEC International Standards and/or European Standards are repeated below for convenience in most cases. NOTE 2 Other language versions may contain an alphabetical index in national annexes. 3.1 auxiliary energy electrical energy used by heating, cooling and/or domestic water systems to transform and transport the delivered energy into the useful energy [CEN/TR 15615] NOTE 1 This includes energy for fans, pumps, electronics etc., but not the energy that is transformed. Pilot flames are considered as part of the energy use by the system. NOTE 2 In EN ISO 9488 the energy used for pumps and valves is called "parasitic energy". SIST EN 15232:2007

3.9 energy use for space heating or cooling or domestic hot water energy input to the heating, cooling or hot water system to satisfy the energy need for heating, cooling or hot water respectively. It is the sum of the energy needs and the non-recovered technical system thermal losses [prEN 15306] NOTE The energy use for lighting is also considered in this European Standard. 3.10 energy performance of a building calculated or measured amount of weighted net delivered energy actually used or estimated to meet different needs associated with a standardised use of a building, which may include, inter alia, energy used for heating, cooling, ventilation, domestic hot water and lighting [CEN/TR 15615] . 3.11 control function BACS effect of programs and parameters [EN ISO 16484-2:2004] NOTE 1 Functions within a BACS are referred to as control functions, I/O, processing, optimization, management and operator functions. They are listed in the BACS FL (function list) for a specification of work. [EN ISO 16484-2:2004] NOTE 2 Function is a program unit that delivers exactly one data element, which can be a multiple value (i.e. an array or a structure). Functions can be an operand in a program. [IEC 61131-3:2003] SIST EN 15232:2007

the impact of the accuracy of the control system on the energy performance to be taken into account.

Technical Building Management 5 Impact of BACS and TBM on the energy performance of buildings 5.1 General Building Automation and Control (BAC) equipment and systems provides effective control functions of heating, ventilating, cooling, hot water and lighting appliances etc., that lead to increased operational and energy efficiencies. Complex and integrated energy saving functions and routines can be configured on the actual use of a building depending on the real user needs to avoid unnecessary energy use and CO2 emissions. Technical Building Management (TBM) functions as part of Building Management (BM) provide information about operation, maintenance, services and management of buildings especially for energy management – Measurement, recording trending, and alarming capabilities and diagnosis of unnecessary energy use. Energy management is a requirement about documentation, controlling, monitoring, optimisation, determination and to support corrective action and preventive action to improve the energy performance of buildings.
5.2 BAC Efficiency Class
Functions having an impact on the energy performance of buildings are listed in Table 1. They are split in three groups: functions for automatic control, functions for home automation system/building automation and control system and functions for technical home and building management. Four different BAC efficiency classes (A, B, C, D) of functions are defined either for non – residential and residential building. – Class D corresponds to non energy efficient BACS. Building with such systems shall be retrofitted. New buildings shall not be built with such systems. – Class C corresponds to standard BACS. – Class B corresponds to advanced BACS and some specific TBM functions. – Class A corresponds to high energy performance BACS and TBM. Table 1 defines the list of functions corresponding to each level. To be in class C minimum functions defined in Table 1 shall be implemented.
NOTE In addition the hydraulic system shall be properly balanced. SIST EN 15232:2007

One is in class D if the minimum functions to be in class C are not implemented. 5.3 BAC and TBM functions having an impact on the energy performance of buildings The most common BAC and TBM functions having an impact on the energy performance of buildings have been summarized in Table 1. Functions are assigned to the BAC efficiency classes as defined in clause 5.2 depending on their use in residential or non-residential buildings.
Table 1 should be applied in the following way by: a) building owners, architects or engineers defining the building automation and controls (BAC) and technical building management (TBM) functions to be implemented for a given new building or for the renovation of an existing building: 1) They can put an X in front of each of the functions they want to be implemented. They will use the shaded boxes as an help tool to determine in which class A, B, C, D the function they have specified is located. To achieve for example category B the X shall all be put in a shaded box for category B; 2) It will be a simplified alternative especially for specification at an early stage of a project to specify only the classes of function A, B, C, D; b) public authorities defining minimum requirements for BAC and TBM functions for new buildings as well as for renovations as defined in EN 15217:2005, D.3: 1) They can define the minimum class to be achieved. Unless differently specified this class is C; c) public authorities defining inspection procedures of technical systems as well as inspectors applying these procedures to check if the level of BAC and TBM functions implemented is appropriate: 1) Public authorities can request the use of the table to inspect the BACS in place; 2) Inspectors can put an X in front of each of the BAC functions which are implemented; 3) They will then be able to determine the class A, B, C, D of functions already implemented. To be in a given class all the X shall correspond to shaded boxes for this cclass; d) public authorities defining calculation methods which take into account the impact of BAC and TBM functions on the energy performance of buildings as well as software developers implementing these calculation methods and designers using them: 1) Public authorities can request that the impact of the BAC and TBM functions defined in the list is taken into account; 2) Software developers can develop software user interfaces enabling to input the list of BAC and TBM functions which are implemented according to Table 1. They can provide a simplified input mode based on the class of functions A, B, C, D; SIST EN 15232:2007
