## Abstract

The present disclosure includes an air guide assembly for cooling the inside of a building or refreshing the air inside of a building. The air guide assembly may be operatively coupled around, near, or at the opening of a building. In some aspects, the air guide assembly includes a body configured for re-directing an air current, a frame for supporting the body, a mounting device for supporting the frame and/or body, and an articulation member for positioning the body at a suitable angle for re-directing an air current into the building, or a combination thereof. In addition, methods of cooling the inside of a building or refreshing the air inside a building using an air guide assembly disclosed herein are described.

## Claims

### Claim 1

An air guide assembly, the assembly comprising:
a frame configured to be disposed adjacent to an opening of a building; and
a body operatively coupled to the frame, the body having a surface configured to deflect an air current into the opening while the frame is operatively coupled to the building;
wherein the surface of the body is angularly disposed relative to the opening at an angle between about 20° to 80°.

### Claim 2 (depends on 1)

The assembly of claim 1, wherein the angle is about 45°.

### Claim 3 (depends on 1)

The assembly of claim 1, wherein the body comprises plastic, metal, or glass.

### Claim 4 (depends on 1)

The assembly of claim 1, wherein the body is translucent.

### Claim 5 (depends on 1)

The assembly of claim 1, wherein the body comprises a concave side.

### Claim 6 (depends on 1)

The assembly of claim 1, wherein the frame further comprises a mounting device configured to operatively couple the frame to the building.

### Claim 7 (depends on 1)

The assembly of claim 1, wherein the body defines a cavity.

### Claim 8 (depends on 1)

The assembly of claim 1, wherein a horizontal cross-section of the body has a polygonal, pyriform, or oval shape.

### Claim 9 (depends on 1)

The assembly of claim 1, comprising an articulation member configured to move the surface of the body relative to the opening to adjust the angle.

### Claim 10

A method for cooling a building, the method comprising the steps of:
operatively coupling a frame of an air guide assembly to a portion of a building defining an opening, the air guide assembly including:
the frame; and
a body operatively coupled to the frame, the body having a first surface configured to direct air into the opening; and
positioning the first surface of the body relative to the opening at a first angle between about 20° to 80°.

### Claim 11 (depends on 10)

The method of claim 10, wherein the first angle is about 45°.

### Claim 12 (depends on 10)

The method of claim 10, comprising:
determining a direction of an air current; and
based on the direction of the air current, rotating the first surface to a second angle relative to the opening that is distinct from the first angle; and
wherein the air flow into the opening is greater while the first surface is disposed at the second angle than the first angle.

### Claim 13 (depends on 12)

The method of claim 12, wherein rotating the first surface includes moving a rod operatively coupled to the body, the rod extending into the opening of the building.

### Claim 14 (depends on 10)

The method of claim 10, wherein:
the body includes a second surface angularly disposed relative to the opening at a third angle;
the third angle being substantially equal to and opposite of the first angle.

### Claim 15 (depends on 10)

The method of claim 10, wherein:
the body includes:
the first surface disposed relative to the opening at the first angle;
a second surface disposed relative to the opening at a second angle; and
a third surface disposed relative to the opening at a third angle; and
the first angle is greater than the second angle; and
the second angle is greater than third angle.

### Claim 16 (depends on 15)

The method of claim 15, wherein:
the second surface is further from the opening than is the first surface; and
the third surface is further from the opening than is the second surface.

### Claim 17 (depends on 10)

The method of claim 10, wherein operatively coupling the frame to the building comprises attaching a side of the frame to an exterior of the building by means of a mounting device.
