## Abstract

A system, device and method for reducing wind-induced vibration using cladding includes one or more movable panels attached to an outer façade of a high-rise building, skyscraper or any other structure subject to wind-induced vibration.

## Claims

### Claim 1

A system for reducing wind-induced vibration, comprising:
a cladding comprising a plurality of movable panels;
a means for attaching the cladding to a structure;
a means for moving the movable panels; and
a processor configured to control the movement of the movable panels using the means for moving the panels.

### Claim 2 (depends on 1)

The system of claim 1, wherein the structure is a building.

### Claim 3 (depends on 1)

The system of claim 1, wherein the structure is a building and the cladding is attached to at least a portion of an outer façade of the building.

### Claim 4 (depends on 1)

The system of claim 1, wherein the structure is a building and at least a portion of the cladding forms a corner of the building.

### Claim 5 (depends on 1)

The system of claim 1, wherein one or more of the movable panels comprises a transparent or translucent portion.

### Claim 6 (depends on 1)

The system of claim 1, wherein the processor is configured to control the movement of the movable panels by adjusting an amplitude and/or frequency of one or more of the movable panels.

### Claim 7 (depends on 6)

The system of claim 6, wherein the processor is configured to control the movement of the movable panels in response to wind speed and/or direction parameters.

### Claim 8 (depends on 6)

The system of claim 6, wherein the processor is configured to control the movement of the movable panels in response to wind speed and/or direction parameters detected by a sensor attached or in proximity to the building.

### Claim 9 (depends on 1)

The system of claim 1, wherein the means for attaching the cladding to a structure comprises a plurality of sliding tracks configured to allow and/or control movement of the plurality of movable panels.

### Claim 10 (depends on 1)

The system of claim 1, wherein the means for moving the movable panels comprises:
a) a hydraulic system; and/or
b) at least one motor.

### Claim 11 (depends on 1)

The system of claim 1, wherein the processor is further configured to:
receive parameters describing wind speed and direction; and
control the movement of the movable panels based upon the received parameters.

### Claim 12 (depends on 1)

The system of claim 1, further comprising:
a sensor configured to detect wind speed and direction parameters, wherein the processor is further configured to control the movement of the movable panels based upon the detected wind speed and direction parameters.

### Claim 13 (depends on 1)

The system of claim 1, wherein the structure is a building and the processor is further configured to move the movable panels at a frequency and/or amplitude that reduces wind-induced vibration of the building.

### Claim 14 (depends on 1)

The system of claim 1, wherein the structure is a building and the processor is further configured to move the movable panels at a frequency and/or amplitude that minimizes wind-induced vibration of the building.
