Revolving doors. They’re everywhere — at the entrances of office buildings, hotels, retail stores, airports, and more — but it wasn’t always so. In fact, the first one to appear in a U.S. building arrived in 1899. (Shown above: Theophilus Van Kannel‘s 1888 patent drawing for a “Storm-Door Structure.”)
Yet despite revolving doors’ ubiquity and central placement in building designs, not to mention the fact that they are proven energy savers, the evidence shows that, when given an option between revolving doors and standard swinging doors, the majority of people choose traditional doors for entering and leaving buildings.
Why is this so, and what can be done about it? 99% Invisible, a terrific podcast on design and architecture, recently posted a great episode on this very subject.
