Resumen:
This European Standard 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.The methods do not apply to heated or chilled ceiling panels or beams.The aim of the present standard is not the evaluation of cooling load for dynamic simulations, but to give a guide for dimensioning Thermo Active Building Systems (TABS), which can enable the use of renewable energy sources.This Standard allows the calculation of peak cooling capacity of a thermo active building system (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 standard defines even a detailed method aimed at the calculation of heating and cooling capacity in unsteady state conditions. Steady state heating capacity is calculated according to method B or E in Part 2 of this series of standards instead.
