Small Issue – Revolving Doors

I have always tried to avoid revolving doors, but after one awkward situation I started to hate this invention. Every time entering the building through RD, I plan my “go through” strategy well in advance, considering the number of people around, the room between panels etc.

And I am not the only person who feels uncomfortable using the abovementioned type of doors. You can find many forum topics where people discuss their plans to destroy this evil technology.

But more and more offices and shopping malls use RD system despite its high price, and it can be the best evidence that it is not so bad. So let’s try to understand why.

The first advantageous point is that, comparing to all other types of doors, RD allow larger quantities of people to enter and leave the building simultaneously together with controlling the density of flow.

The second positive point is that they do not allow air to leave or come into the building saving the right pressure and temperature inside. Therefore, they save massive amounts of energy and consequently money, which could be spent for heating or cooling.

Of course, RD are not perfect. They have very high price and installation costs comparing to other door types.  Moreover, you can’t install them without providing the building with standard hinged doors because of fire security.

In conclusion, it is to say that revolving doors is a very beneficial invention that helps to save environment, keep the building clean and regulate people flow. Therefore, people have to get used to them.

P.S. Just some interesting facts about RD:

- Energy from single 1 door use can power 60 watt light bulb for 23 minutes.

- Keeps snow, dust and dirt out of the building.

- Officially was invented in 1888 by Theophilus Van Kannel. However, some say that it was in use since 1790.

- Manufacturing process does not contain harmful chemicals or wastes.

- Men go first.

- Revolving doors were advertised as safe for health of the people who stay near constantly opening doors.
