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 heating or cooling medium. The ISO 11855 series is not applicable for testing of systems.
The methods do not apply to heated or chilled ceiling panels or beams.
The object of the ISO 11855 series is to provide criteria to effectively design embedded systems. To do
this, it presents comfort criteria for the space served by embedded systems, heat output calculation,
dimensioning, dynamic analysis, installation, control method of embedded systems, and input
parameters for the energy calculations.
The ISO 11855 series consists of the following parts, under the general title Building environment
design — Embedded radiant heating and cooling systems:
— Part 1: Definitions, symbols, and comfort criteria
— Part 2: Determination of the design heating and cooling capacity
— Part 3: Design and dimensioning
— Part 4: Dimensioning and calculation of the dynamic heating and cooling capacity of Thermo Active
Building Systems (TABS)
— Part 5: Installation
— Part 6: Control
— Part 7: Input parameters for the energy calculation
ISO 11855-1 specifies the comfort criteria which should be considered in designing embedded radiant
heating and cooling systems, since the main objective of the radiant heating and cooling system is to
satisfy thermal comfort of the occupants. ISO 11855-2 provides steady-state calculation methods for
determination of the heating and cooling capacity. ISO 11855-3 specifies design and dimensioning
methods of radiant heating and cooling systems to ensure the heating and cooling capacity. ISO 11855-4
provides a dimensioning and calculation method to design Thermo Active Building Systems (TABS)
for energy saving purposes, since radiant heating and cooling systems can reduce energy consumption
and heat source size by using renewable energy. ISO 11855-5, this document, addresses the installation
process for the system to operate as intended. ISO 11855-6 shows a proper control method of the radiant
heating and cooling systems to ensure the maximum performance which was intended in the design
stage when the system is actually being operated in a building. ISO 11855-7 presents a calculation
method for input parameters to ISO 52031.
