The EN 1264 series gives guidelines
for surface embedded heating and cooling systems installed in
buildings, residential and non-residential (e.g. office, public,
commercial and industrial buildings) and focuses on systems
installed for the purpose of thermal comfort.
The EN 1264 series gives guidelines
for water based heating and cooling systems embedded into the
enclosure surfaces of the room to be heated or to be cooled. It
also specifies the use of other heating media instead of water, as
appropriate.
The EN 1264 series specifies
standardized product characteristics by calculation and testing the
thermal output of heating for technical specifications and
certification. For the design, construction and operation of these
systems, see EN 1264?3 and EN 1264?4 for the types A, B,
C, D, H, I and J. For the types E, F and G, see the EN ISO 11855 series.
The systems specified in the EN 1264 series are adjoined to
the structural base of the enclosure surfaces of the building,
mounted directly or with fixing supports. The EN 1264 series does not specify
ceiling systems mounted in a suspended ceiling with a designed open
air gap between the system and the building structure which allows
the thermally induced circulation of the air. The thermal output of
these systems can be determined according to the EN 14037 series and EN 14240.
EN 1264?5 specifies the
recalculation of values determined in EN 1264?2 for the system in
question. It enables the conversion of the calculation and
measurement results of EN 1264?2 into results for
other surface orientations in the room, i.e. for ceiling and wall
heating, as well as for the application as cooling surfaces, i.e.
for floor, ceiling and wall cooling. The test results of EN 1264?2 are the basis of all
calculation, whether or not the system in question is used for
heating or cooling application.
