The Light + Air door is designed to enhance cross ventilation without giving up any security or light. Slide a lever to the right, and the circular openings are exposed—not big enough for anyone to stick a hand in and open the door, but large enough to let the sunshine and fresh air pass through.
Who wants to live without air-conditioning if there is poor ventilation? The Light + Air Door design concept is an answer to that pressing and probably upcoming problem: how do you stay comfortable when it costs $2000 a month to keep your abode cool? Just don't install this door if you live in a submarine.
