SIST EN 15232:2012
EN 15232:2012 (E) 4 Introduction 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 also provides guidance for taking BACS and TBM functions as far as possible into account in the relevant standards prepared under the mandate M/343. Therefore, it is coordinated between CEN/TC 247 and CEN/TC 89, CEN/TC 156, CEN/TC 169 and CEN/TC 228 to support these TCs by strong cooperation in specifying how the impact of the BACS and TBM functions are taken into account in their standards. The results concerning BACS and TBM in the relevant standards are summarized in Clause 5. This European Standard specifies a method to estimate energy saving factors which can be used in conjunction with energy assessment of buildings. This European Standard supplements a series of standards which are drafted to calculate the energy efficiency of technical building services, e.g. heating, cooling, ventilation, lighting systems. This European Standard takes into account the fact that with BACS and TBM the energy consumption of a building can be reduced. This European Standard should be used for existing buildings and for design of new or renovated buildings. SIST EN 15232:2012
EN 15232:2012 (E) 5 1 Scope 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. NOTE The terms BAC (Building Automation and Control) and BACS (Building Automation and Control System) are equivalent in view of energy calculation and energy efficiency. In this case BACS will be used in the English version and BAC (German term: "GA Gebäudeautomation") in the German version. 2 Normative references The following referenced documents are indispensable for the application of this document.

Building Management DHW Domestic Hot Water EMS Energy Management System HVAC Heating, Ventilation and Air Conditioning TABS Thermo-active Building Systems TBM Technical Building Management 5 Impact of BACS and TBM on the energy performance of buildings 5.1 General Building Automation and Control Systems (BACS) provide effective control functions of heating, ventilating, cooling, hot water and lighting appliances etc., that lead to improve operational and energy efficiencies. Complex and integrated energy saving functions and routines can be configured based on the actual use of a building, depending on 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 provides requirements for documentation, controlling, monitoring, optimisation, determination and to support corrective action and preventive action to improve the energy performance of buildings. The BACS functions described in Table 1 are based on the energy demand and supply model for a building in Figure 1. SIST EN 15232:2012
EN 15232:2012 (E) 12
Figure 1 — Energy demand and supply model (Example: Heating plant) Rooms represent the source of the energy demand. Suitable equipment should ensure comfortable conditions in the rooms with regard to temperature, humidity, air quality and light as needed and with due consideration of minimum or maximum requirements specified in local regulations. Supply media is provided to the consumer according to energy demand keeping losses in distribution and generation to an absolute minimum. The building automation and control functions described in Table 1 are aligned in accordance with the energy demand and supply model. The relevant energy-efficiency functions are handled starting with the room, via distribution up through generation. 5.2 BACS and TBM functions having an impact on the energy performance of buildings The most common BACS and TBM functions having an impact on the energy performance of buildings have been described and summarized in Table 1.

FprEN 15232:2011 (E) 5 Introduction 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 also provides guidance for taking BACS and TBM functions as far as possible into account in the relevant standards prepared under the mandate M/343. Therefore it is coordinated between CEN/TC 247 and CEN/TC 89, CEN/TC 156, CEN/TC 169 and CEN/TC 228 to support these TCs by strong cooperation in specifying how the impact of the BACS and TBM functions are taken into account in their standards. The results concerning BACS and TBM in the relevant standards are summarized in Clause 5. This European Standard specifies a method to estimate energy saving factors which can be used in conjunction with energy assessment of buildings. This European Standard supplements a series of standards which are drafted to calculate the energy efficiency of technical building services, e.g. heating, cooling, ventilation, lighting systems. This European Standard takes into account the fact that with BACS and TBM the energy consumption of a building can be reduced. This European Standard should be used for existing buildings and for design of new or renovated buildings. kSIST FprEN 15232:2011
FprEN 15232:2011 (E) 6 1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document.
