The dynamic thermal simulation has become a recognized instrument to predict building thermal behaviour. Many tools were developed in the last decades, which were independently validated, by considering different operating conditions, and rarely were directly compared in the same conditions. The objective of this work is to evaluate the prediction accuracy of the most popular building performance simulation tools, namely TRNSYS, EnergyPlus and IDA ICE, by means of a comparison of the simulated results and the experimental measurements detected under real operating conditions.

Temperature control is one of the most significant factors to improve the performance
and extend the cycle life of a battery. It is, therefore, important to design and implement
an effective battery thermal management system (TMS). Phase change materials (PCMs)
can be used as a cooling means for batteries. In the present paper, a preliminary analysis
of the thermal behavior of PCMs used to cool down a heated metal surface was carried
out. Tests have shown that pure PCMs are able to limit the temperature increase, but
