Climate classification for the simulation of thermally activated building systems (TABS)

Thermally activated building systems (TABS) provide high temperature cooling and low temperature heating which has a better efficiency compared to traditional heating and cooling solutions. Additionally the moderate required temperature levels for heating and cooling create the opportunity to use alternative (sustainable) energy sources that would otherwise be insufficient. The design of TABS is however challenging and most often requires a complete simulation of the building. The standard ISO 11855-4 (2011) suggests a simplified sizing method for TABS. The results however omit condensation risk entirely. The proposed climate classification should fill this gap by providing the missing data in a simple manner.
