In the borough of Queens in New York City is John F. Kennedy International Airport. It is the busiest US airport by international passenger traffic.

Due to the gradual increase in passenger traffic, some of the main entrances to the JFK airport equipped with revolving doors were left without sufficient capacity to channel the traffic of large numbers of passengers at peak times, often accompanied by carts and lugagge, causing queues and circulation problems.

To solve the situation, the airport commissioned the improvement of its access facilities with three objectives; a greater capacity of traffic channeling through the doors, an improvement of the energy saving in the entrances and a minimum impact in the facade of the building.

After analyzing several proposals, it was decided not to change the revolving doors for larger ones. In this way, it was possible to maintain the entire structure of the building and substantially reduce the total budget for the project. But then, how would it be increased the number of people per minute passing by the door?

Taking advantage of the structure of the revolving door, its wings were removed and replaced by two automatic sliding doors covering the entire diameter, thus ensuring maximum capacity and ease of movement.

Three or four wing revolving door can reduce the amount of energy needed to heat or cool a building, which provides optimum energy savings and reduces carbon footprint, sliding doors are more inefficient but combined with a high efficiency air curtain, are the perfect solution to create an invisible barrier that separates two different environments without limiting the access of people.

The air curtain would be placed following the curvature of the revolving door structure. The technological challenge in this case consisted of the dimensions of the revolving door (almost 5 meters in diameter) much larger than standard revolving doors. In addition, the energy saving and performance of the air curtain is important, but equally important is the aesthetics. It required an air curtain that would seamlessly integrate into airport interior design and technically feasible.

Airtècnics designed a high powered Rotowind air curtain with high efficiency EC fans, hot water heating, with an outlet divided into two parts to cover the entire radius of curvature and painted the same white color of the building structure.

The solution adopted for the 8 entrances of the New York JFK airport with this capacity to channel the traffic problems has been a success; With a minimum budget, the facility is now more functional, maintains a harmony in the design, saves more energy and provides more comfort to the traveler.
