EnergyPlus, IDA ICE and TRNSYS predictive simulation accuracy for building thermal behaviour evaluation by using an experimental campaign in solar test boxes with and without a PCM module

•The most popular BPS tools, namely TRNSYS, EnergyPlus and IDA ICE, are compared.•Two different small-scale solar test boxes were employed for the accuracy assessment.•The comparison was developed both in the presence and absence of a PCM module on the floor.•Warm, intermediate and cold periods were...
