“…They regulate indoor daylight and prevent glare and overheating, and improve the energy efficiency of buildings 5,6 . Chromogenic materials switch from a passive (bleached) state to an active (colored) state when certain values of environmental parameters are reached (photochromic 7 , thermochromic 8 , thermotropic 9 ) or under the influence of electrical voltage (electrochromic 10 ). Gasochromic coatings 11 operate under alternating exposure to hydrogen and oxygen.…”

“…Liquid crystal glasses 12 and suspended particles devices 13 are electrically controlled. Smart windows [5][6][7][8][9][10][11][12][13] operate regardless of the position of the Sun and do not adapt to the angles of incidence of solar rays. They weaken not only direct, but also diffuse solar radiation, which is undesirable for creating a comfortable light environment.…”

This paper presents methods for calculating the direct light transmittance of a double-grating optical filter. Based on these methods, numerical simulations were carried out, the results of which were confirmed by experiments under direct collimated white light without the influence of diffuse light using two grating smart window models with different sets of strip widths, as well as a model of a conventional window with clean glass. The results showed that by pre-calculating the angle of inclination, the widths of the strips of both gratings and their relative position, taking into account the coordinates of the building and the azimuth of the window, the filter provides angular selectivity of transmission without the use of shading/redirection devices. Window transmission with such a filter is minimized during specified times of the selected day when the need for sun protection is greatest. Due to the angular selective light transmission and the ability to adjust the inclination of the gratings to the trajectory of the Sun, such filters are promising for use in smart windows for optimal filtration of direct solar radiation indoors.
