Abstract:
1. A method for individualized and automated control of means for closing off at least one window of a building, the method comprising, acting on closing-off means associated with at least one window according to the orientation of direct rays of sunlight as defined by a solar azimuth and a solar elevation by: determining coordinates of at least one dazzle cone associated with a window, and with a dazzle-sensitive zone situated inside the building in which said window resides, said at least one dazzle cone being defined by a vertex point positioned in the dazzle-sensitive zone, said vertex point being selected by a user of said method, and a directrix corresponding to the perimeter of said window by identifying a plurality of directional axes each passing through the vertex point of said dazzle cone and through one of a plurality of reference points on the perimeter of the window, each of which points (n) is defined by the azimuth (An) and elevation (En) of the directional axis passing through said point; storing the azimuth and elevation of each of said plurality of directional axes which define the dazzle cone; periodically checking whether the direction of direct rays of sunlight entering said window falls within at least one predetermined dazzle cone, and passes through the vertex of said cone by comparing the direction of said rays of sunlight to the directions of said directional axes which define the dazzle cone; and if the result of said periodic checking shows that the direction of said rays of sunlight corresponds to a directional axis within the defined dazzle cone, acting on the closing-off means associated with said window.
