Abstract: An energy saving grate installed outside a building or structure in warm weather that reduces heating due to infrared radiation (IR) from sunlight. For a window application the grate acts as a sunshade to block or diffuse the IR and ultraviolet (UV) portions of sunlight while passing visible light. The grate cell size, depth, cell surface characteristics, and mounting details near the sash determine system performance of sunlight control, of the view through the grate, and of the exterior appearance. The grate is removable for cool weather. The grate system can cool various surfaces and requires no operating adjustments. It can be applied near most windows (including skylights) on all sides of a building where impinging sunlight causes unwanted heating. Compared to external solar thin mesh screens the grate system can provide more open area for a given performance in reduced IR heating.

Abstract: Each light slat of the Mini-Optical Light Shelf daylighting system consists of a light reflecting segment that comprises the top surface of the light slat. A light shading segment and a light redirecting segment comprise the bottom surface of the light slat. The daylight incident on the daylight collection section of the glazing is collected by the optically shaped light reflecting segment of the light slats and redirected onto the ceiling plane of the room in a glare free, uniform manner. In addition, the light redirecting segment of each light slat functions to redirect incident daylight, that is reflected off the light reflecting segment of the adjacent light slat at angles above a predetermined threshold, onto the ceiling plane of the room. The light shading segment functions to block low altitude components of incident daylight from entering the room.

The mini-optical light shelf comprises multiple shelves, each of which contains an identical optically shaped top surface to allow light to be efficiently collected and accurately directed onto the ceiling surface. The optical shelves are narrow and can be implemented in the paradigm of a window treatment. The window area is partitioned into a view related glazing section and a daylight collection and redirection glazing area.

Abstract: The shading system includes a plurality of shading elements forming groups of elements for each window of a building. The elements generally have non-horizontal and non-vertical slope and tilt angles. The slope and tilt angles are determined by the latitude of the building and compass bearing of a plane through the window. All of the elements for each window lie parallel to one another and are nonmovable. By calculating slope and tilt angles for each compass bearing and building latitude, the solar heat gain in the summer can be minimized and solar heat gain in the winter can be maintained.

Abstract: A window has a rectangular frame with pivotable sections movable between an opened and closed position. A level connected to a movement transmission bar is provided to pivot the sections about pegs mounted to a support in the frame. The level is of a deformable material and has a detent on a shaft thereof. The detent will engage a first or second opening in the frame to lock the sections in an opened or closed position.
