A window structure is configured to form a principal chamber enclosing a first window pane installed in an exterior wall of a building. The window structure includes a first surface configured to absorb solar energy and a main frame including a second window pane. An axial hinge is configured to allow to the main frame to tilt between a first position and a second position. When the main frame is tilted in the first position, the first surface is positioned in a first orientation that allows the first surface to directly receive sunlight through the second window pane. When the main frame is tilted in the second position, the first surface is positioned in a second orientation in which the first surface is prevented from directly receiving sunlight through the second window pane. The window structure may be used for ventilating the structure and shading during the warm weather.

A shutter assembly comprising a shutter door, an inner frame and an outer frame, wherein the shutter door defines an aperture and includes two or more rotatable vanes, wherein the vanes have a first orientation in which they completely obscure the aperture and a second orientation in which they partially obscure the aperture; the shutter door is hingedly coupled to the inner frame; and the inner frame is secured to the outer frame.

A cabinet may include a top surface and a front side allowing access to an interior of the cabinet. The cabinet may also include a front panel, which may have a flat surface that is larger than the top surface. The front panel may be pivotable between a first configuration, in which the front panel is a vertical panel closing the front side, and a second configuration, in which the front panel forms a horizontal table top.

Rotating door systems and methods for rotating a plurality of rotatable doors between a closed position and an open position are provided. Each of the rotatable doors may have a height measured in a vertical direction between opposing horizontal edges, a width measured in a horizontal direction between opposing vertical edges, and an axis of rotation centrally located between the opposing vertical edges. The rotatable doors may be rotatably coupled to an upper support at the axis of rotation via an upper pivot shaft and rotatably coupled to a lower support at the axis of rotation via a lower pivot shaft. The rotatable doors may be at least partially transparent. The rotation of one or more of the rotatable doors may be controlled by a controller.
