## Abstract

A method of inspecting an exterior elevated element of a building is provided. The method drills a hole into an interior space of the exterior elevated element of the building. The interior space of the exterior elevated element encompasses a plurality of wooden surfaces. The method passes a camera through the hole into the interior space of the exterior elevated element of the building. The method captures a set of one or more images from the wooden surfaces in the interior space of the exterior elevated element by the camera. The method analyzes the set of images to identify one or more of color differences of the wooden surfaces, color intensity differences of the wooden surfaces, and a shape and a size of any cracks on the wooden surfaces. The method determines the existence of wood rot in the interior space of the exterior elevated element based on the analysis.

## Claims

### Claim 1

A method of providing ventilation for an interior space of an exterior elevated element of a building, the exterior elevated element comprising one of a deck, a porch, a balcony, a stairway, a walkway, and a landing, the method comprising:
providing a ventilation window;
wherein the ventilation window comprises a plurality of railings;
wherein the ventilation window comprises a plurality of brackets;
wherein each bracket is attached to one or more ball bearings configured to move along a corresponding railing to bring the attached bracket to a vicinity of a joist in the interior space of the exterior elevated element;
wherein each bracket is configured to be connected to a joist to install the ventilation window on an underside of the exterior elevated element;
moving at least one ball bearing to bring the attached bracket to a vicinity of a joist in the interior space of the exterior elevated element; and
connecting the corresponding bracket to the joist to install the ventilation window on the underside of the exterior elevated element.

### Claim 2 (depends on 1)

The method of claim 1 further comprising installing at least one fan configured to circulate air between the interior of the exterior elevated element and an outside of the exterior elevated element.

### Claim 3 (depends on 2)

The method of claim 2 further comprising:
installing a humidity sensor in the interior space of the exterior elevated element;
communicatively coupling the humidity sensor with a processor of a hub;
receiving humidity measurements by the processor from the humidity sensor;
turning the fan on by the processor when the humidity measurements exceed a threshold humidity value; and
turning the fan off by the processor when the humidity measurements are less than or equal to the threshold humidity value.

### Claim 4 (depends on 3)

The method of claim 3 further comprising:
installing a moisture sensor in the interior space of the exterior elevated element;
communicatively coupling the moisture sensor with the processor of the hub;
receiving moisture measurements by the processor from the humidity sensor;
turning the fan on by the processor when the moisture measurements exceed a threshold moisture value; and
turning the fan off by the processor when the moisture measurements are less than or equal to the threshold moisture value.

### Claim 5 (depends on 3)

The method of claim 3 further comprising:
installing a temperature sensor in the interior space of the exterior elevated element;
communicatively coupling the temperature sensor with the processor of the hub;
receiving temperature measurements by the processor from the temperature sensor;
turning the fan on by the processor when the temperature measurements exceed a threshold temperature value; and
turning the fan off by the processor when the temperature measurements are less than or equal to the threshold temperature value.

### Claim 6 (depends on 2)

The method of claim 2 further comprising starting and stopping the fan based on a schedule, the schedule comprising a period of the fan being on and circulating air, followed by a period of the fan being off.

### Claim 7 (depends on 2)

The method of claim 2 further comprising:
installing an environmental sensor in the interior space of the exterior elevated element, the environmental sensor comprising one of a humidity sensor, a moisture sensor, and a temperature sensor;
communicatively coupling the environmental sensor with a processor of a hub;
receiving environmental parameter measurements by the processor from the environmental sensor;
turning the fan on by the processor when a value of the environmental parameter exceeds a threshold value; and
turning the fan off by the processor when the value of the environmental parameter is less than or equal to the threshold value.

### Claim 8 (depends on 7)

The method of claim 7, wherein the hub is communicatively coupled by one or more electronic devices outside the building.

### Claim 9 (depends on 7)

The method of claim 7 further comprising generating a warning by the processor when the value of the environmental parameter exceeds the threshold value for a threshold time period.

### Claim 10 (depends on 7)

The method of claim 7, wherein exterior elevated element is a first exterior elevated element of the building, wherein the hub is communicatively coupled to at least one more environmental sensor and one more fan installed in an interior space a second exterior elevated element of the building, wherein the second exterior elevated element is one of a deck, a porch, a balcony, a stairway, a walkway, and a landing.

### Claim 11 (depends on 7)

The method of claim 7, wherein the environmental sensor is a first environmental sensor, wherein threshold value is a first threshold value, the method further comprising:
installing a second environmental sensor in the interior space of the exterior elevated element, the environmental sensor comprising one of humidity sensor, a moisture sensor, and a temperature sensor;
communicatively coupling the second environmental sensor with the processor of the hub;
receiving environmental parameter measurements by the processor from the second environmental sensor; and
turning the fan on by the processor when a value of the second environmental parameter exceeds a second threshold value; and
turning the fan off by the processor when the value of the first environmental parameter is less than or equal to the first threshold value and the value of the second environmental parameters is less than or equal to the second threshold value.
