A gutter uplift channel assembly is configured to mount skylights, smoke vents, or other roof accessories to a roof having a pair of longitudinally extending roof curbs. A gutter extends between the pair of roof curbs and is secured to the roof curbs to channel water laterally over the roof curbs. The gutter receives longitudinal ends of a pair of roof accessories to be mounted next to each other. An uplift channel or cap of the gutter channel assembly extends over the longitudinal ends or rims of the roof accessories and is secured to the gutter via threaded rods extending up from the gutter through corresponding holes in the uplift channel and nuts placed on the threaded rods.

A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.

In a roof window system, the housing (6) of the ventilation unit (5) is prepared for accommodation of a standard ventilator and/or a regenerator allowing an air current through a ventilation passage (28), from an exterior grating (18) to a ventilation panel (3) integrated into or in continuation of a lining panel of a room in the interior of the building in which the roof window is installed.

In a roof window system, the roof window (1) has a frame with a frame top member (21), and a sash with a sash top member (31), and further a ventilation device (40) for connection to a ventilation assembly by means of transition means provided between the ventilation assembly and the frame top member (21) and the sash top member (31) of the roof window (1) to accommodate a set of flow paths for air to and from the ventilation assembly. The transition means comprise a plurality of apertures (2102) extending through the frame top member (21).

Agricultural structures for housing livestock and/or agricultural commodity, the structure having a floor that is inclined between first and second walls and a roof that is substantially parallel to the floor. In some aspects, the floor is configured such that a bottom of the first wall is vertically higher than a bottom of the second wall with the bottoms of the first and second walls being level with the underlying ground. In some aspects, a first portion of the floor adjacent to the first wall is at a first elevation, a second portion of the floor adjacent to the second wall is at a second elevation that is vertically lower than the first elevation, and a bottom of the first wall is at a third elevation that is equal to or lower than the first elevation.

A smoke vent including a curb and door assembly utilizing a continuous hinge assembly that extends an entire length of a door. Hinge members of the door assembly and curb define continuous, extruded hinge members such that the door is supported across the entire length of the hinge members, whereby localized deflection of the curb is avoided. By supporting the door across the entire length of the hinge member, a door seal can be evenly compressed against the curb so as to prevent moisture/water intrusion when the door is in a closed disposition. The door assembly can further include a dome member that substantially defines an upper and lower surface of the door(s). Each door can comprise a plurality of retainer clips that positively couple the dome member to extruded members that define a door frame while providing a moisture resistant seal between the dome member and the door frame.

An indirect light skydome with natural ventilation for building roofs consists a half sphere dome with a curved brim (101) and an air vent (102) around the dome (100), which attached to the horizontal circular base (.sub.6) with a fan shape opening to allow only indirect sunlight and connected to the tube for light transmission inside the building. The dome (100) is divided into transparent part (1) for receiving only indirect light and opaque part (2) for direct light protection, which are made into a single dome using a coating technique to prevent rainwater leakage in the joints. The shading part and the fan shape opening correspond to the sun's angle for effective direct light protection during the daytime and all year round. The air vent (102) is designed for effective air flow for stack and cross ventilation in all directions. The indirect light skydome with natural ventilation helps to reduce heat and increase quality of daylight.

This disclosure relates to a louvered patio cover. The louvered patio cover may comprise a frame with support beams, louvered panels, support beam couplers, an actuator, a gutter, and/or other components. The support beams may have angled ends. The louvered panels may be rotatably coupled to the support beams. A support beam coupler may comprise first and second receivers. The first receiver may be configured to receive an angled end of a first support beam, and the second receiver may be configured to receive an angled end of a second support beam. The angled ends of the first and second support beams may face, meet, and/or abut each other when received by the first and second receivers. The actuator may be configured to rotate the louvered panels. A gutter may comprise a lighting channel configured to hold a light source for lighting an area under the louvered patio cover.

A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.
