EN 15232:2007 (E) 4 Foreword This document (EN 15232:2007) has been prepared by Technical Committee CEN/TC 247 “Building automation, controls and building management”, the secretariat of which is held by SNV. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by January 2008. This standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/343), and supports essential requirements of EU Directive 2002/91/EC on the energy performance of buildings (EPBD). It forms part of a series of standards aimed at European harmonisation of the methodology for the calculation of the energy performance of buildings. An overview of the whole set of standards is given in CEN/TR 15615. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. SIST EN 15232:2007
EN 15232:2007 (E) 5 Introduction This European Standard was devised to establish conventions and methods for estimation of the impact of building automation 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 impacts of the BACS and TBM functions are taken into account in their standards. The results about 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 BAC and BM 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 15232:2007

Processing of data and information is possible. NOTE 2 When a Building Control System, Building Management System or Building Energy Management System is in compliance with the requirements of the EN ISO 16484 standard series, it should be designated as a Building Automation and Control System (BACS). 3.4 building management BM the totality of services involved in the management operation and monitoring of buildings (including plants and installations).

The losses resulting from the transformation of these renewable energy carriers into heat or electricity are also not taken into account. Only the energy delivered by the generation devices and the auxiliary energy needed to supply the energy from the source (e.g. solar panel) to the building are taken into account in the energy balance and hence in the delivered energy.

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.
