European foreword
This document (CEN/TR 15232-2:2016) 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 has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
This document is currently divided into the following parts:
— Energy performance of buildings — Part 1: Impact of Building Automation, Controls and Building
Management - Modules M10-4,5,6,7,8,9,10 [currently at Enquiry stage];
— Energy performance of buildings — Part 2: Accompanying prCEN/TR 15232-1:2015 Modules M10-
4,5,6,7,8,9,10 [the present Technical Report; currently at Voting stage].
Introduction
The CENSE project, the discussions between CEN and the Concerted action highlighted the high page
count of the entire package due to a lot of “textbook” information. This resulted in flooding and
confusing the normative text.
A huge amount of informative contents shall indeed be recorded and available for users to properly
understand, apply and nationally adapt the EPB standards
The detailed technical rules in CEN/TS 16629, "Detailed Technical Rules" 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 shall be accompanied by an informative technical report, like this one,
where all informative contents is collected.
