Energy-efficient windows incorporating spectrally selective optical elements capable of providing desirable optical characteristics (transmission, reflection, refraction or diffraction) for different wavelengths are disclosed herein. More specifically, energy-efficient windows incorporating suitably designed diffraction gratings to optimize the efficiency of the utilization of different spectral components of the solar radiation are disclosed.
