This part of ISO 11855 allows the calculation of peak cooling capacity of Thermo Active Building
Systems (TABS), based on heat gains, such as solar gains, internal heat gains, and ventilation, and the
calculation of the cooling power demand on the water side, to be used to size the cooling system, as
regards the chiller size, fluid flow rate, etc.
This part of ISO 11855 defines a detailed method aimed at the calculation of heating and cooling
capacity in non-steady state conditions.
The ISO 11855 series 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. It does not apply to panel systems with
open air gaps which are not integrated into the building structure.
The ISO 11855 series also applies, as appropriate, to the use of fluids other than water 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.
