Title

Fundamental Research on Solar Photothermal Utilization in Insulated Glazing Envelopes Embedded with Phase Change Materials

Abstract

The building sector accounts for approximately 37% of global carbon emissions. Developing low-carbon technologies for building envelopes by harnessing renewable energy represents an effective approach to reducing conventional energy consumption and mitigating global environmental challenges. Glass envelopes are closely linked to internal energy demands such as heating, air conditioning, ventilation, and lighting. As the primary components responsible for thermal losses and gains, optimizing glass envelope systems to enable coordinated solar photothermal utilization is a critical step toward advancing low-carbon building envelopes. Glazing envelopes embedded with phase change materials enhance the thermal storage capacity of glass systems, enabling spatial and temporal regulation of intermittent and uneven solar energy. This offers a promising solution to reduce building energy consumption and increase the thermal inertia of glazing systems. This presentation will review the current state of research on glazing envelopes embedded with phase change materials, including advances in thermal storage and insulation materials, photothermal transmission control mechanisms, and the impact on indoor light-thermal environments. A summary and future outlook of glazing energy saving technologies will also be provided.
