In all interior rooms, there will be solar tube lighting. This will be as straight of a pathway as possible, and intended to provide natural sunlight in closets, bathrooms, and all interior spaces. By having solar tube lighting, it would allow me to have light in the room without it consuming electricity. Since this is natural sunlight, there is nothing that needs powering. All spaces will also have a light switch for backup lighting for when the sunlight is not available, but this should be kept to a minimum, and it makes no sense to have a light on in these rooms during the day.
