An air mixing system includes a building superstructure having an open space therein and an attic. An air mixing unit mounted to the ceiling draws air from the open space and the attic, mixes the air and discharges the mixed air outwards from the fan.

A system for retaining a flowable and curable building material to form a portion of a foundation includes side walls disposed in a predetermined configuration having a first side wall and a second side wall, and at least one component having an interior cavity disposed in one of the side walls. A bracket assembly includes an outwardly bounding reinforcement post for each of the side walls, a separator bar having a plurality of apertures sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component. A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.

There is disclosed an improved wall panel trim reveal system and method which utilizes a set of vertical, horizontal and corner trim pieces designed to be fitted together. In an embodiment, the system includes horizontal trim pieces having at least one slope, vertical trim pieces having at least one tab forming a slot for receiving one or more horizontal trim pieces therein, wherein the horizontal and vertical trim pieces when installed together with wall panels forming a moisture drainage channel to direct moisture away from the wall.

A plurality of ventilation elements, vents, slots, or gap elements or similar features that are applied to, or machined into, one or more sides or faces of exterior siding products. When the exterior siding product is installed, the ventilation elements, vents, slots, or gap elements or similar features provide a built-in air and water gap to facilitate and increase water drainage and air circulation behind the siding or panel, thereby minimizing water storage in the space behind the product and lowering the equilibrium moisture content of the siding itself. The ventilation features are incorporated into the corresponding product in-line or during the manufacturing process, and do not require any further work during assembly or construction on-site (e.g., furring strips or other similar drainage mechanisms are not needed).

A building panel may be installed below a slab in the construction of buildings. The building panel supports the slab and also provides a ventilation layer that may be depressurized to eliminate or reduce infiltration of radon gas into the building. The ventilation layer may comprise channels which provide a two-dimensionally interconnected void. Ventilation panels which include collars for connecting to ventilation systems may be provided. The panels may be installed directly on compacted soil. The building panels may additionally provide sub-slab insulation and/or a capillary break for water drainage. In some embodiments the building panels are formed substantially entirely of thermal insulating material such as rigid polystyrene foam. In an example embodiment the panels are approximately 4 inches thick and have a grid of intersecting channels formed on an underside of the panels.

A system for integrated water management of a basement is disclosed. The basement has a footer, a wall extending upward from the footer, and a sill plate on top of the wall. The system may include a sill plate barrier with a base located between the sill plate and the wall. The system may include a vertical barrier coupled to the sill plate barrier and extending downward along an exterior of the wall toward the footer. In addition, the system may have a footer barrier coupled to the vertical barrier and extending over an exterior of the footer. The system may include a drain member adjacent the exterior of the footer and coupled to the footer barrier. In one version, the sill plate barrier, vertical barrier, footer barrier and drain member collectively form the integrated water management system for the exterior of the basement to prevent water intrusion.

A building rail system. The system includes large and small building rails capable of forming flush connections at varied angles. The flush connection of the rails eliminates an extra layer of space that would otherwise exist if the rails had to be offset to form a connection.

Disclosed in the present invention is a structure for blocking heat transfer through a thermal bridge of a curtain wall building, including a curtain wall, an indoor metal frame, an outdoor metal frame and/or metal components, wherein: an integral thermal break strip, which is installed close to an outside and made of an aerogel thermal insulation blanket, is fixed between the indoor metal frame and the curtain wall and/or the outdoor metal frame and/or the metal components. The present invention has simple structure, convenient construction technology, great structural strength, excellent fireproof performance; low comprehensive construction cost and substantially improved energy-saving effect of the curtain wall.

Disclosed herein are methods and systems designed to eliminate or otherwise substantially reduce the amount of water from rainfall that comes into contact with the foundation of a building and the basement walls. Methods and systems described herein will in many instances save users thereof thousands of dollars in costs associated with repairing basement walls that have become cracked or otherwise damaged due to exposure to water and associated structural damage.
