【 摘 要 】

Applicability of phase changing materials (PCMs) in buildings by their integration into the structure of finishing materials structure in the form of particles is especially high as a mean of providing heat-insulation during summer. Materials containing particles with phase changing behaviour are successfully applied at objects with large daylight areas, focused on active utilization of sunlight energy, among others. Utilization of PCM components allows saving considerable amount of energy due to possible refusal of air-conditioning while providing heat-insulation during summer. The paper deals with the lifecycle analysis of gypsum-based finishing products. Main challenges with respect to the lifecycle of products with PCM components are the preservation of their longevity as well as their potential for reuse/recycling. Through the example of PCM-enhanced plaster covering and gypsum plasterboard factors affecting the preservation of the advantageous thermal properties of PCMs over extended periods were studied, along with options of refining materials and products containing different amounts of PCM components. The results of the research allow comparing similar materials with the use of PCM components and without them as well as analyzing the life cycle related environmental performance of PCM-enhanced finishing materials.
