European foreword
This document (CEN/TR 12098-6:2022) has been prepared by Technical Committee CEN/TC 247
“Building Automation, Controls and Building Management”, the secretariat of which is held by SNV.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 12098-6:2016 and CEN/TR 12098-8:2016.
The most important changes in comparison with CEN/TR 12098-6:2016 are:
— respecting the presentation of this project in the frame EPB in accordance with the drafting rules;
— improvements in line with EN 12098-5:2017.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
Introduction
This document is part of the set of EPB (Energy Performance of Building) standards that aim to support
the implementation of the Energy Performance of Buildings Directive (EPBD). This document contains
informative content for users to properly understand, apply and nationally adapt the EPB standards.
This document follows the basic principles (CEN/TS 16628, Energy Performance of Buildings — Basic
Principles for the set of EPB standards) and detailed technical rules (CEN/TS 16629, Energy Performance
of Buildings — Detailed Technical Rules for the set of EPB-standards) elaborated by CEN.
The detailed technical rules CEN/TS 16629 ask for a clear separation between normative and informative
contents:
— to avoid flooding and confusing the actual normative part with informative content;
— to reduce the page count of the actual standard;
— to facilitate understanding of the package.
Therefore, each EPB standard should be accompanied by an informative technical report, like this one,
where all informative content is collected.
Table 1 shows the relative position of this document within the EPB set of standards.
