Revolving Door

Definition

A revolving door is typically a four-panel door attached at 90 degrees to each other that turns on a center axis.

Purpose

The purpose of a revolving door is to provide continuous access while minimizing air exchange between the inside and outside of a building, thus improving energy efficiency and controlling building climate.

Examples of Use

• Office buildings use revolving doors to manage high foot traffic and maintain indoor temperature.
• Hotels often have revolving doors at their main entrances for a grand, efficient entryway.
• Airports utilize revolving doors to facilitate smooth and controlled passenger flow.

Notes

Revolving doors can significantly reduce heating and cooling costs by limiting the amount of air that escapes or enters the building, making them a popular choice for energy-conscious design.
