Abstract: The paper presents the results of numerical analysis of complex, triple glazed window with PCM layer. The optical properties substitution due to change of phase is executed by refined control algorithms for windows. The idea of the control/actuator algorithm and its implementation in ESP-r software was described. Using the proposed method the simulations were executed for two extreme summer months under moderate climatic conditions. Five different paraffin waxes were analysed as a PCM filling and compared with traditional triple glazed window. The results were analyzed in terms of energy for cooling, energy for lighting, visual discomfort, glare effect and thermal discomfort. It was concluded that there is no one optimal type of PCM, and the best solution is to divide the glazing into sections filled with PCM with different melting temperatures.
