EXTERNAL ENVELOPE Don’t get in a spin


James White of Record UK breaks down the various factors to consider when specifying a revolving automatic door


building. They also prevent unwanted air infiltration, reduce energy costs and contribute to a superior indoor climate, making them a popular choice for architects, specifiers and end users. As with all automatic door systems, the key to success post-occupancy and overall client satisfaction, is correct specification from the early design phase. This is where the manufacturer’s specification managers enter the equation offering technical advice and support in the design and integration of the revolving door to all involved. After all, if the revolving door becomes a barrier to access due to incorrect specification, it may lead to dissatisfaction once in operation due to queues forming at peak times. To avoid this and ensure success, there are many factors that should be considered.

Floor space, occupancy and peak flow


The theoretical pedestrian flow rate of a revolving door is dictated by its proposed internal diameter, quantity of wings, and peripheral speed (constrained by regulation EN16005). Therefore, an understanding of the predicted demand at peak times is essential to determine the minimum diameter of revolving doors required, as well as the overall number of units. As an example, a typical four-wing automatic revolving door with a diameter of 2400 mm, rotating at 0.77 m/s or 6.12 rotations per minute, would have a throughput capacity of approximately 31 people per minute or 1,900 people per hour, based on one person occupying each segment. Of course, a large influx of workers will enter an office building between 8:30 am and 9:30 am each morning. A single revolver might quickly become overwhelmed when large volumes of pedestrians arrive at the same time. A pass door may be needed as an alternative point

of entry – somewhat defeating the indoor climate benefits intended when selecting a revolving door. This is particularly relevant during inclement weather conditions and additional doors should be considered to remove the risk of queues forming, especially considering the current need for social distancing. As an alternative, a high throughput


curved sliding door system might be a consideration or even as an addition when pedestrian footfall demand might overwhelm a revolver’s capacity. A curved sliding door offers relatively unimpeded traffic flow, it can be used on an emergency escape route and can create a very similar aesthetic to a revolving door. It is more challenging to control the indoor climate with this type of system but the addition of a warm air curtain, reduced opening width in the winter and interlocking the inner and outer doors (where possible) can help to negate this. The added benefit of a curved slider is that you do not need a separate pass door.
