Improving building thermal comfort through passive design – An experimental analysis of phase change material 3D printed concrete

Multi-Faceted Analysis of Phase-Change Composite Intended for Autonomous Buildings

“…This is required because of the sensitivity of the statistical test used to peak measurements. The verification was carried out according to Equations ( 8) and (9).…”

“…Storage of heat and cold by increasing the thermal capacity of building elements is one of the solutions used today to reduce the energy demand of buildings and improve their thermal comfort, as confirmed in [ 6 , 7 ]. Effectively increasing the thermal capacity of building components or their systems in an isothermal form and small footprint, according to [ 8 , 9 , 10 ], is possible using phase-change materials. Phase-change materials are incorporated both in the form of new composites applied conventionally or 3D printed [ 9 ] and for retrofitting existing buildings by injecting organic PCMs into walls and ceilings, as described in [ 11 , 12 ].…”

The use of phase-change materials in construction as building components or furnishing undoubtedly increases the thermal capacity of buildings and can contribute to improving indoor thermal comfort.…”

Application of Novel Phase Change Material Constructive Solution for Thermal Regulation of Passive Solar Buildings

“…Notably, the U.S. Department of Energy (DOE) has recognized the use of PCMs as the system most capable of thermal latent heat storage in passive solar designs [9]. Due to their promising capabilities, PCMs have been extensively researched for innovative applications in buildings in recent years, including mortars and concrete [8,[10][11][12][13], masonry technologies and bricks [14,15], plastic foams [16], gypsum boards [17,18], and passive solar applications [19,20]. The integration of PCMs into building materials or systems offers a promising means of mitigating indoor temperature fluctuations, thereby enhancing overall energy efficiency.…”

“…The integration of PCMs into building materials or systems offers a promising means of mitigating indoor temperature fluctuations, thereby enhancing overall energy efficiency. Notably, the study by Christen et al [10] demonstrated a significant reduction in maximum indoor temperatures, by up to 3.9 • C, achieved through the use of 3D-printed concrete with PCM incorporated via vacuum impregnation. Likewise, Mahdaoui et al [15] explored the application of a hollow building brick with microencapsulated PCM, achieving a 2 • C reduction in daily thermal amplitude.…”
