“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:

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.

5 Control heating systems, general design rules
5.1 Control heating systems, main design rules, general design rules

Efficient Heating control system consists on integrated functions applied to all parts of heating system

taking account predictable or detected occupancy and other events as smart metering information, ...

etc.
5.2 Partitioning control heating zones in buildings

For efficiently control heating, the heating power shall satisfy heat demand. For this purpose, heating

power is compensated by outside temperature and scheduled for intermittent heating in relation with

conditions of use. For efficiency of control systems, the heating system distribution building shall be

partitioned into zones or spaces with uniform conditions of use,

NOTE Partitioning of heating systems described on prEN ISO 52000-1:2015, 9, D.2, D.3, may usefully be

applied for the design of heating systems.

BAC heating control system shall have multiple controls and intermittent scheduling adapted to zones

or elementary spaces conditions of use. Special attention shall be done to keep watch for update set

points and schedulers to real conditions of use and needs, du
