Thermal and uncertainty analysis of a lightweight floor with integrated TABS and ventilation system

Abstract

The HiLo living lab combines numerous novel multifunctional building elements, including a floor system that integrates TABS and ventilation system into complex geometry and lightweight structural components. The purpose of this study is to investigate the operational performance of the floor system and to compare it with the performance predicted by a white-box model in TRNSYS. Although the model can accurately and reliably predict the actual performance of the floor system with a median CV-RMSE index of 3.35%, the limited variability in the data and the unique conditions of the living lab may limit the generalisability of the model.
