Applications in buildings
Thermochromic materials, in the form of coatings, can be applied in buildings as a technique of passive energy retrofit. Thermochromic coatings are characterized as active, dynamic and adaptive materials that can adjust their optical properties according to external stimuli, usually temperature. Thermochromic coatings modulate their reflectance as a function of their temperature, making them an appropriate solution for combating cooling loads, without diminishing the building's thermal performance during the winter period.
