Energy Saving By Revolving Door

Whether you believe or not, the revolving door could save much more energy compared with sliding door or swing door. 

In the year 2006, some students at MIT conducted an analysis of door use in one building, where they found just 23 percent of visitors used the revolving doors. According to MIT's calculations, the swinging door allowed as much as eight times more air to pass through the building than the revolving door. According to the April 2009 MIT Tech Talk publication, Research from MIT students indicates that if everyone were to use the revolving doors in the Building, it could save almost USD 7,500 in natural gas a year, which could be enough to heat at least 5 houses over the same timeframe, and it also adds up to nearly 15 tons of CO .

With the same situation, after the calculation, the sliding door allowed as much as about 10 times more air to pass through the building than the revolving door.  The chart below could make us know the energy saving better.

If possible, kindly suggest to install the revolving door, it could not only save us more money finally, but also do some positive contributions to the environment protection.

Note : The automatic revolving door is ingeniously structured, typically consisting of two wings which rotating with the ceiling together, and three/four wings hanging on a central shaft, rotating smoothly around a vertical axis within a cylindrical enclosure. Driven by a high-performance motor and controlled by an intelligent system, it operates quietly and stably, with adjustable rotation speed to adapt to different pedestrian flows. The glass wings, made of high-strength tempered glass or laminated glass, not only ensure clear visibility for pedestrians to avoid collisions but also add a sense of transparency and spaciousness to the entrance, blending perfectly with various architectural styles, whether it is a modern minimalist building or a luxurious classic structure, the automatic revolving door can complement it harmoniously.
