European foreword
This document (CEN/TR 16946-2:2016) 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:
— Inspection of Building Automation, Controls and Technical Building Management — Module M10-11
[currently at Enquiry stage];
— Inspection of Building Automation, Controls and Technical Building Management — Part 2:
Accompanying prEN 16946-1:2015 Modules M10-11 [the present Technical Report; currently at
Voting stage].
Introduction
The CENSE project, the discussion 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 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 shall be accompanied by an informative technical report, like this one,
where all informative content is collected.
Table 1 shows the relative position of this standard within the EN EPB set of standards.

4 BAC audit methodology
4.1 Introduction
Building Automation and Controls including Technical Building Management (BAC) contribute to the
performance of buildings. BAC performance has a tendency to decline over time if not actively checked,
maintained and adapted to the actual use of the building (independent of the building type). This
performance depends on a number of factors. Some of the factors are:
— building / space usage changes
— equipment maintenance and re-commissioning
— manual interventions and missing “back to “normal” change
— manual set point adjustments and back to “normal” procedure
This technical recommendation describes a methodology to audit “BAC” in any state of its
implementation in a building.
An inspection shall:
— hold all important data for a specific BAC
— keep track of the inspected BAC portion and its model data
— produces a report (e.g. on paper and/or electronically)
— acts as base for improvement measures determination
