The thesis explores the use of phase change materials (PCM) in lime-cement plasters, which can contribute to improving the energy efficiency of buildings. The ability of PCM to absorb and release heat during phase transitions can help reduce the need for heating and cooling, thus lowering greenhouse gas emissions. We incorporated PCMs into plasters, where they act as thermal regulators by storing heat during warmer periods and releasing it when temperatures drop, providing passive thermal insulation. The theoretical part provides a detailed overview of PCM materials, their microencapsulation, and their impact on the mechanical and thermal properties of the mortar. The experimental section includes testing three different mortar mixtures with the addition of 20% and 30% PCM, compared to a reference mixture. The test results show that PCM reduce the compressive and flexural strength of the plasters, while simultaneously increasing heat storage and prolonging the heat release duration. The conclusions highlight the potential of PCM in creating sustainable and energy-efficient buildings, as their use in building materials enables passive regulation of indoor temperatures, contributing to reduced energy consumption and lower heating and cooling costs.
