Nevertheless, the phase change effect is quite a complex phenomenon for numerical modelling and different methods can be used to estimate the results of latent heat storage. This paper presents a brief overview of the existing numerical methods and a short description of two most frequently used ones. Authors also investigated the capabilities of phase change modelling by three simulation tools. This work is a part of a wider research project which aims to find optimal solution of façade construction with the implementation of PCM. The choice of a proper numerical method was considered the first step to achieve this goal.</p>
