It has also been demonstrated that the introduction of PCMs with different melting temperatures provides materials with energy storage capacity for different climatic conditions (summer or winter times). In this way, by changing the PCM melting temperature, new stone products can be designed for different climate conditions of different regions and for special exposure conditions. The new products are appropriate for indoor or outdoor applications (tiles, plates and slabs used for cladding, roofing, flooring, systems for ceilings, walls and floors) where energy consumption is crucial for the energy performance of buildings.
