Highlights Gypsums with up to 15wt% of different thermoregulating microcapsules were produced. Density, porosity, thermal stability and compressive strength were studied. A homemade equipment was used to measure the c p, k and TES capacity. 4.5kWh/operating cycle are saved in a standard room with 1m3 of this material. 1.395kg of CO2 emissions are reduced in a standard room with 1m3 of this material.
Abstract Smart gypsum composites were manufactured by adding different kinds of microcapsules containing phase change materials (PCMs) in order to develop building materials with high thermal energy storage (TES) capacity useful for being applied in high comfort constructive systems. The physical, thermal and mechanical properties of these composites such as density, porosity, thermal stability, thermal conductivity (k), equivalent heat capacity (c p), the accumulated heat power (q acc) and the maximum compressive strength were studied. Results showed that the higher the microcapsules content, the lower the density and k and the higher the c p and q acc, due to the PCM action. Besides, the addition of 15wt% of microcapsules respect to the hemihydrate would allow to save 4.5kWh of energy per operating cycle in a standard room covered with 1m3 of this gypsum. This energy is equivalent to the energy spent by three incandescent light bulbs of 60-W kept on all the day and a reduction of 1.395kg of CO2 emissions to the atmosphere. The addition of these thermoregulating materials to gypsum decreases their compressive strength but all the developed materials satisfied the Spanish mechanical regulations for gypsum as building material, being possible to increase the total amount of added microcapsules.
