Building environment design - Embedded radiant heating and cooling systems - Part 5: Installation (ISO 11855-5:2021)
This document establishes requirements for the installation of embedded radiant heating and cooling systems. It specifies general and uniform requirements for the design and construction of heating and cooling floors, ceiling and wall structures to ensure that the heating/cooling systems are suited to the particular application. The requirements specified by this document are applicable only to the components of the heating/cooling systems and the elements which are part of the heating/cooling surface and which are installed due to the heating/cooling systems.
This document is applicable to water-based embedded surface heating and cooling systems in residential, commercial and industrial buildings. The methods apply to systems integrated into the wall, floor or ceiling construction without any open-air gaps, but are not applicable to panel systems with open-air gaps which are not integrated into the building structure.
Umweltgerechte Gebäudeplanung - Flächenintegrierte Strahlheizungs- und -kühlsysteme - Teil 5: Installation (ISO 11855-5:2021)
Dieses Dokument legt Anforderungen für die Installation flächenintegrierter Strahlungsheiz- und kühlsysteme fest. Es werden allgemeine und einheitliche Anforderungen an die Auslegung und Konstruktion der Fußboden-, Decken- und Wandheiz- und kühlsysteme bestimmt, um die Tauglichkeit der Heiz- bzw. Kühlsysteme für ihre jeweilige Anwendung sicherzustellen. Die in diesem Dokument festgelegten Anforderungen sind nur für die Komponenten der Heiz- bzw. Kühlsysteme sowie für die Elemente, die Teil der Heiz- bzw. Kühloberfläche sind und im Zusammenhang mit dem Heiz- bzw. Kühlsystem installiert werden, anwendbar.
Dieses Dokument ist für integrierte Flächenheiz- und kühlsysteme mit Wasserdurchströmung in Wohn-, Gewerbe- und Industriegebäuden anwendbar. Die Verfahren sind für in Wände, Boden und Deckenkonstruktionen flächenintegrierte Systeme ohne offene Luftspalte anwendbar. Die Verfahren sind nicht anwendbar für Flächensysteme mit offenen Luftspalten, die nicht in die Gebäudestruktur eingebunden sind.
Conception de l'environnement des bâtiments - Systèmes intégrés de chauffage et de refroidissement par rayonnement - Partie 5 : Installation (ISO 11855-5:2021)
Le présent document établit les exigences relatives à l’installation de systèmes intégrés de chauffage et de refroidissement par rayonnement. Elle spécifie des exigences générales et uniformisées pour la conception et la construction des structures de chauffage et de refroidissement par le sol, le plafond et les murs, permettant de garantir que les systèmes de chauffage/refroidissement sont adaptés à l’application considérée. Les exigences spécifiées dans le présent document ne s’appliquent qu’aux composants des systèmes de chauffage/refroidissement et aux éléments constituant la surface de chauffage/refroidissement installés en raison de la présence des systèmes de chauffage/refroidissement.
Le présent document s’applique aux systèmes intégrés de chauffage et de refroidissement de surface à eau dans les bâtiments résidentiels, commerciaux et industriels. Ces méthodes s’appliquent aux systèmes intégrés dans les murs, sols ou plafonds, sans ouverture à l’air libre. Elles ne s’appliquent pas aux systèmes de panneaux avec ouvertures à l’air libre, qui ne sont pas intégrés dans une structure de bâtiment.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

This second edition cancels and replaces the first edition (ISO 11855-5:2012), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— modified Clause 2 (Normative references) and the Bibliography;
— modified Clause 4 (Symbols);
— added a new subclause on vapour barrier and other layers (see 5.1.2.2);
— modified the subclause on insulating layers, perimeter insulating strip adding a new approach and
adding details for thermal resistance of insulating layer (see 5.1.2.3);
— added new subclauses on insulating layers for systems in new constructions (see 5.1.2.3.2) and in
refurbished systems (see 5.1.2.3.3);
— modified the subclauses on joints (see 5.1.2.8.3), leak test (see 5.1.3), initial heating up of the
emission system (see 5.1.4) and general structural preconditions (see 5.2.2);
— removed the subclause on maximum heating fluid flow temperatures (previously 5.2.4);
— improved wording and made editorial changes.

ISO 11855-5:2021(E)
Introduction
The radiant heating and cooling system consists of heat emitting/absorbing, heat supply, distribution,
and control systems. The ISO 11855 series deals with the embedded surface heating and cooling system
that directly controls heat exchange within the space. It does not include the system equipment itself,
such as heat source, distribution system and controller.
The ISO 11855 series addresses an embedded system that is integrated with the building structure.
Therefore, the panel system with open air gap, which is not integrated with the building structure, is
not covered by this series.
The ISO 11855 series is applicable to water-based embedded surface heating and cooling systems
in buildings. The ISO 11855 series is applied to systems using not only water but also other fluids or
electricity as a he
