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 mod-erate required temperature levels for heating and cool-ing create the opportunity to use alternative (sustain-able) energy sources that would otherwise be insuffi-cient.
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 simpli-fied sizing method for TABS. The results however omit condensation risk entirely. The proposed cli-mate classification should fill this gap by providing the missing data in a simple manner.
