Content of EN 15232 Standard EN15232: "Energy performance of buildings – Impact of <strong>Building</strong> Automation, Control and <strong>Building</strong> Management" provides guidance for taking BACS and TBM functions as far as possible into account in the relevant standards. This standard specifies • a structured list of control, building <strong>automation</strong> and technical building management functions which have an <strong>impact</strong> on the energy performance of buildings • a method to define minimum requirements regarding the control, building <strong>automation</strong> and technical building management functions to be implemented in buildings of different complexities, • detailed methods to assess the <strong>impact</strong> of these functions on the energy performance of a given building. These methods enable to introduce the <strong>impact</strong> 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 <strong>impact</strong> of these functions on the energy performance of typical buildings. 18
3.3 eu.bac Certification eu.bac Cert is a joint venture of eu.bac and various European certification bodies and test laboratories in conformity with the relevant provisions of the EN 45000 set of standards. EU mandate for CEN to standardize calculation methods to improve energy efficiency TC247: EN 15232 "Energy performance of buildings – Impact of <strong>Building</strong> Automation" and Product Standards • Terminology • Product data incl. energy performance criteria • Test procedure Rules Test Tool Independent certifier Accredited laboratory eu.bac Cert guarantees users a high level of • energy efficiency, and • product and system quality as defined in the corresponding EN/ISO standards and European Directives. Some public organizations approve only eu.bac-certified products. Calculation standard Product standards and certification 3.4 Standardization benefits The EN 15232 standard clearly shows for the first time the huge potential energy savings that can be achieved in the operation of technical building systems. Consequently, all planners should apply the EN 15232 standard. Planners are generally familiar with energy requirements and are therefore able to provide construction owners with information on the benefits of building <strong>automation</strong>. Manufacturers of building <strong>automation</strong> facilities should also use the EN 15232 standard for assessment purposes when carrying out modernization work. Product standards such as EN 15500 "<strong>Building</strong> <strong>automation</strong> for HVAC applications – electronic individual zone control equipment" define energy efficiency criteria that are verified and certified by eu.bac. Product users can therefore be sure that the promised characteristics and quality are indeed delivered. 19
