The Revolving Door

While it may be a rare occasion, we’ve probably all encountered a revolving door at one point in our life. It was likely entering a large building that sees a high amount of foot traffic. There is a reason for a revolving door being their choice and we’ll get to that later. As this style of door is virtually never used in homes it begs the question, why do revolving doors exist? Is it simply for aesthetic reasons? Let’s dig deeper into the reasons, which will end up being quite obvious, as to why the revolving door was invented.

The Need for Revolving Doors

Why were revolving doors invented? One story claims that they came about as a means to keep horses out of buildings. That reason may not seem so farfetched as the door was invented in 1888, a time when horses were a main method of transportation.  Another claim is that the inventor, Theophilus van Kannel, designed the door so that he would not have to hold the door open for people as they entered the building. While there are many tales as to the reason behind the revolving door, efficiency is the only one that is true.

Benefits of Revolving Doors

Did you ever get yelled at as a kid to “shut the door, we’re not heating the neighborhood”? Your parents wouldn’t have been able to say that had your house had a revolving door. This is the largest benefit of revolving doors, their ability to minimize the amount of air that transfers between the inside and outside of the home. This reduces energy consumption and thus energy costs. As far as businesses go, this type of door offers even more benefits. They allow for people to enter and exit the building at the same time rather than single file. They also prevent debris from entering the building, great for the fall and winter seasons.
