Due to latent heat storage potential, phase change materials can be implemented in building materials to improve energy performance and thermal comfort. 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.

PL
The paper summarizes the methods of calculating heat gain by transparent insulation using two national standards. The energy balance of the partition was evaluated taking its orientation into account. A comparison was conducted into the methods of assessing the effectiveness of transparent insulation.
