In this paper, we report the application of VO2 on ceramic tiles aiming to control the reflected infrared radiation on smart roofs and thus improving the energy efficiency, which is associated to the reduction of the carbon dioxide emissions. The VO2 nanoparticles have been produced by hydrothermal synthesis assisted by microwave irradiation, providing a new, quicker and cleaner production route. Afterwards, the VO2 nanoparticles were transferred to the surface of ceramic glassy tiles, which were prepared through dispersing the nanopowders in water and followed by spray coating with posterior annealing treatments in order to promote the surface adhesion as well as the stabilization of the material monoclinic phase. The VO2 transition temperature was controlled by doping with tungsten and a reduction from 69 °C to 49 °C was achieved. The superior thermochromic characteristics of VO2 nanoparticles in conjunction with this new application to a smart roof offers a great potential to regulate the energy in an intelligent way. © 2016 Published by Elsevier B.V.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 3</style></notes></record></records></xml>
