Building environment design — Design, test methods and control of hydronic radiant heating and cooling panel systems — Part 6: Input parameters for the energy calculation
This document establishes guidelines for the determination of input parameters for ceiling mounted radiant heating and cooling panels in relation to ISO 52031. 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 panels and which are installed to provide heating and/or cooling. This document is applicable to water-based ceiling mounted radiant heating and cooling panels in residential, commercial and industrial buildings. The methods apply to systems mounted under the ceiling with an open air gap between the panels and the ceiling. This document also applies, as appropriate, to the use of fluids other than water as a heating or cooling medium. This document is also applicable for testing of systems. The methods do not apply to heated or chilled ceiling beams.

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.

Introduction
The radiant heating and cooling system consists of heat emitting/absorbing, heat supply, distribution
and control systems. Typical applications are low temperature radiant heating and high temperature
radiant cooling. They are classified as embedded radiant heating and cooling systems and prefabricated
radiant heating and cooling panel systems.
While the ISO 11855 series is for embedded radiant heating and cooling systems without an open-
air gap, the ISO 18566 series is for radiant heating and cooling panel systems with an open air gap.
Because the system specifications for ISO 18566 are different from those of ISO 11855, it was necessary
to develop separate ISO standards regarding the design and test methods of the cooling and heating
capacity and control.
ISO 18566-1 specifies the comfort criteria, technical specifications and requirements which should be
considered in the manufacturing and installation of radiant heating and cooling systems. ISO 18566-2
provides the test facility and test method for heating and cooling capacity of ceiling mounted radiant
panels. ISO 18566-3 specifies the design considerations and design processes of ceiling mounted radiant
panels. ISO 18566-4 addresses the control of ceiling mounted radiant heating and cooling panels to
ensure the maximum performance which was intended in the design stage when the system is actually
being operated in a building. This document presents a determination method of input parameters for
1)
the energy efficiency of heating and cooling products in relation to ISO 52031.
ISO 18566 does not cover the panels that are embedded into the ceiling, wall or floor structure. This
document is partly based on EN 14240, EN 14037 and ASNI/ASHRAE Standard 138.
