Experimental tile with phase change materials (PCM) for building use

The use of phase change materials (PCM) and their possible architectural integration is a path in the search for optimizing energy efficiency in construction. As part of this path, a pavement has been designed which, in combination with the PCM, serves as a passive thermal conditioning system (new patent n°. ES2333092 A1) [1]. The prototype has been tested experimentally and the results proved that it is a viable constructive solution improving the energy performance of sunny locals.

► In this study we designed a tile with phase change materials (PCM).
► We tested experimentally the tile.
► We compared the prototype with other one without PCM.
► The tiles with PCM store energy in the form of sensible and latent heat.
► The PCM regulate surface temperature of tile between 4 °C and 10 °C with regard to tiles without PCM.
