“…Thereby, wallboards, floors, roof, mortar or concrete and other parts are integrated with PCMs in order to improve the thermal performance of the building [8][9][10][11][12]. The most common solution for implementing PCMs in buildings is the installation of PCM into the interior side of the building envelope.…”

Increasing concerns about climate change and global warming bring about technical steps for the development of several energy-efficient technologies. Since the building sector is one of the largest energy users for cooling and heating necessities, the incorporation of a proper energy-efficient material into the building envelopes could be an interesting solution for saving energy. Phase change material (PCM)-based thermal energy storage (TES) seems suitable to provide efficient energy redistribution. This is possible because the PCM is able to store and release its latent heat during the phase change processes that occurs according to the environmental temperature. The purpose of this paper was the characterization of the thermal properties of a composite PCM (i.e., Lecce stone/poly-ethylene glycol, previously developed) incorporated into mortar compositions based on different binders (i.e., hydraulic lime and cement). The study was carried out using an experimental set up through which it was possible to simulate the different seasons of the years. It was observed that the addition of PCM in mortars leads to a decrease of the maximum temperatures and increase of the minimum temperatures. Furthermore, the results shown a reduction of the heating and cooling needs, thus confirming the capability of this material to save energy.

“…The applications that have been investigated for floor solutions are very varied. The addition of PCMs in the construction can be by adding a single layer of PCM [100,101] or by adding a multilayer of different types of PCMs [102,103]. Additionally, another approach is the development of floor panels with capillary network for PCM circulation [104], or the use of PCMs along with an electrical powered system for diminishing the demanded energy consumption [105].…”

The management of energy consumption in the building sector is of crucial concern for modern societies. Fossil fuels’ reduced availability, along with the environmental implications they cause, emphasize the necessity for the development of new technologies using renewable energy resources. Taking into account the growing resource shortages, as well as the ongoing deterioration of the environment, the building energy performance improvement using phase change materials (PCMs) is considered as a solution that could balance the energy supply together with the corresponding demand. Thermal energy storage systems with PCMs have been investigated for several building applications as they constitute a promising and sustainable method for reduction of fuel and electrical energy consumption, while maintaining a comfortable environment in the building envelope. These compounds can be incorporated into building construction materials and provide passive thermal sufficiency, or they can be used in heating, ventilation, and air conditioning systems, domestic hot water applications, etc. This study presents the principles of latent heat thermal energy storage systems with PCMs. Furthermore, the materials that can be used as PCMs, together with the most effective methods for improving their thermal performance, as well as various passive applications in the building sector, are also highlighted. Finally, special attention is given to the encapsulated PCMs that are composed of the core material, which is the PCM, and the shell material, which can be inorganic or organic, and their utilization inside constructional materials.

“…La Ref. [37], realiza el estudio de la variación de las temperaturas en un periodo de 24 horas utilizando un piso alveolar con una doble capa de capsulas de PCM y una habitación de referencia; los resultados indican que la habitación de referencia tiene una temperatura inicial de 10.5°C y final de 10 °C, mientras que en el piso alveolar relleno con PCM una temperatura inicial de 16.5°C y final de 16°C, representando un aumento de la temperatura promedio en 57.14%. en comparación a la habitación de referencia.…”

Climate change has an impact on all the areas that operate in a construction environment and, essentially, on the life cycle of a home; in which the materials affect the construction process according to their energy content. The adobe is used for its thermal conductivity to improve the internal temperature of a home; However, in cold climates their behavior is not very efficient. In this sense, the phase change material (PCM) can be used as an alternative because it is capable of storing latent heat and increasing the thermal mass of a building. In the present work, 06 insulation systems for walls, ceilings and floors of an adobe house are analyzed thermal insulation system is proposed, and a prototype is made with some components in 3D printing; the results indicate that the systems Trombe-PCM wall, translucent concrete block wall-PCM, false ceiling-PCM, concrete ceiling-PCM, alveolar floor-CM and plasterboard floor-PCM are adequate; with the proposed insulation system, an improvement of 42.71% of the internal thermal comfort is achieved when compared to adobe house without PCM; and an increase of 320.38% with respect to the Imata temperature, while the Trombe-PCM wall system prototype allows to make corrections in the design for its implementation on a real scale.
