  • Patent number: 8601757
    Abstract: Some embodiments provide a fenestration apparatus including at least one glazing pane capable of being installed in an opening of a building envelope and a tessellated structure disposed adjacent to the at least one glazing pane. The tessellated structure can include at least one partition having a first face and a second face. The at least one partition can define a plurality of spatially separated cells within a substantially contiguous region of the opening. Each of the plurality of spatially separated cells can have a cell width and a cell depth. Each of the plurality of spatially separated cells can be at least partially surrounded by the first face of the at least one partition, the second face of the at least one partition, or a combination of the first face and the second face of the at least one partition.

  • Patent number: 8568011
    Abstract: Some embodiments provide a daylighting apparatus comprising an internally reflective tube configured to direct daylight from a first end of the tube to a second end of the tube opposite the first end. A diffuser can be positioned at the second end of the tube. The diffuser can comprise a first optical structure configured such that, when the daylighting apparatus is installed with the first end positioned outside a room and the second end positioned to provide light to the room, a reflected portion of the daylight is directed towards at least one upper region (e.g., a ceiling or upper wall surface) of the room and a transmitted portion of the daylight is directed towards at least one lower region (e.g., a floor surface) of the room.
