Several European Directives, e.g. the Energy Performance of Building Directive and the Energy using Product Directive, require that minimum requirements be specified. These minimum requirements may affect the building design and the technical building systems. The EN 15316-1 Standard defines the efficiency of heating systems or parts of them (subsystems) and introduces the relevant calculation methods. Dividing the general performance of a building, as indicated in EN 15603, makes it possible to identify the strong and the weak points in the total energy performance of a building. EN 15316-1 could also help in the definition and application of specific requirements for heating systems as included in the recast of the Directive.
