In the last few decades, industrialized building construction has been identified as the way to build with greater guarantees in terms of sustainability. The optimization of building components must be priori- tized and windows have high potential for energy savings and solar gain use. Although the advantages of integrating phase change material (PCM) into glazing units have been demonstrated, studies focused on windows are only 8%. Current research mainly tackles the difficulties for effective, reliable and practical applications of PCM. The functioning of PCM makes it necessary to take into account the local climate, the building characteristics, orientation and occupation profile. The objective of the present work is to design and evaluate the performance of an industrialized modular innovative active glazing and heat recovery system using PCM. First, the design and construction of the system focused on harnessing, storing and managing passive solar gains is carried out, followed by a comprehensive experimental comparative analysis. Savings on heating consumption in winter are up to 48%. The objective of harnessing solar radiation is reached and is reflected by a monthly consumption reduction of up to 25%. Future research needs to be performed, integrating user input.
