Provided in one embodiment is a method of modifying an air flow at least one location of a building structure, comprising: generating a first air flow at the at least one location of the building structure; and modifying a second air flow exterior to the building structure using the generated first air flow. An apparatus configured to modified an air flow is also provided.

A post sleeve includes a reinforced concrete body preformed around a liner that defines a cavity extending longitudinally within the body, sized to receive a post. Standoff ribs run lengthwise within the cavity and extend inward from inner walls of the cavity. A post in the cavity is supported laterally by the standoff ribs. Drain channels between the ribs permit water to flow past the post and exit the cavity via a lower aperture. A drain tube is coupled to the lower aperture, and extends downward where it is covered with gravel at the bottom of a post hole. Concrete is poured around the post sleeve in the hole. The cavity is adaptable to receive posts of varying sizes, and at various depths. A collar closes a space between the post and the top of the cavity, permitting air circulation within the cavity while shedding water and substantially preventing insects from entering the cavity.

The invention relates to an elongate tensioning unit comprising a casing which encloses an interior space, and a plurality of tensioning elements which extend in the longitudinal direction of the tensioning unit and are accommodated in the interior space of the casing. According to the invention, the casing comprises, at, at least one circumferential position, a depression which projects into the interior space and in which at least one electric functional unit, for example at least one lighting unit, and at least one connection line for the at least one electric functional unit are accommodated. Alternatively, the at least one electric functional unit can also be accommodated in an associated recess in a water-repelling element arranged on the outer surface of the casing.

A kit that includes multiple rectilinear elongate polygonal elements having five unique shapes, four of which are concave polygonal elements. In some examples, when arranged with respect to one another, the elements of the kit form a girih strapwork pattern. In one aspect, respective elements in a kit may include bezels or boarders along longer sides to enhance an over/under weaving effect of the girih strapwork pattern. In other aspects, one or more elements may be formed as a tray, and some of the trays may include various components or materials disposed in the tray (e.g., architectural surface materials, biological systems, various electronic components) to provide for a variety of creative designs and structural/sculptural installations for built environments. In some implementations, one or more such trays may have beveled rims so as to appear light and thin when viewed.

A flashing for concrete board siding includes a substantially rigid panel, a guide protrusion, an interior protrusion and at least one strip of adhesive double-sided tape. The guide protrusion and interior protrusion are integrally formed with the panel at opposing ends. The at least one strip of adhesive double-sided tape is on an exterior face of the panel. In an embodiment, a channel separates two or more strips. Some embodiments include at least one groove disposed between two or more strips. Further, a method of installing concrete board siding to a structure includes fastening a first piece of cement board siding to the structure, providing an embodiment of the flashing disclosed herein, positioning the interior protrusion on the top edge, adhering a second piece of cement board siding to the least one strip of adhesive double-sided tape and fastening the second piece of cement board siding to the structure.

An adjustable finishing bracket assembly for use in concealing retractable shades, screens, hangers and the like. The assembly employs an L-bracket having slots for horizontal positioning and threaded apertures for securing to a hook bracket. The hook bracket has adjustment slots for securing to the L-bracket and a U-shaped distal end. The hook bracket is securable to the L-shaped bracket and a hanger bracket. A level bolt is connected to the L-shaped bracket. The adjustable finishing bracket provides horizontal, vertical and angular positioning of the wood plank to assure the wood plank is properly aligned and provides an easily removable wood plank for access to the retractable mechanisms.
