Dor-Control Craftsmen Installs Revolving Door at Mount Sinai Hospital to Calm Wind Tunnel Effect, Toronto, ON

Revolving Door at Mount Sinai Hospital Calms Wind Tunnel Effect, Toronto, ON


Toronto is known for its cold and blustery winter months. Before February 2016, Mt. Sinai Hospital employees, patients, and visitors often had to endure freezing wind tunnel conditions within a street-level entrance corridor linking University and Murray Streets. Wind conditions could be so severe that employees using a smaller, employee-designated swinging entrance at times could not manually open that door

“On the hospital’s main floor,” explained Tony Khouri, Vice President, Facilities and Capital Development, “there is a long corridor between University and Murray Streets. Formerly, we had double sliding doors at each entrance, and because of the high foot traffic we had lots of problems with blasts of cold air running up and down the corridor.” The corridor not only connects the two streets to the main entrance of the hospital, but it also has retail and other shops located along its length.

The hospital engaged an expert about renovating the entrances, and the consultant recommended installing revolving doors to stop the infiltration of air. In a competitive bid process, Boon Edam revolving doors were selected.


Throughput was an issue, “Compared to other hospitals, we have a high number of users for these entrances, averaging 1000 per hour,” said Khouri. Mt. Sinai installed a 16’ diameter, dual-wing Duotour at Murray St., the larger of the two main entrances. This entrance is more accessible for patients arriving or leaving by car and can accommodate wheelchairs and patients on stretchers. The smaller entrance, University St., is accessed up a flight of stairs and has been fitted with a 12’ diameter, two-wing Duotour. Both entrances also maintain one set of push-button activated sliding doors alongside the revolving doors to conform with the Ontario Disabilities Act and for emergency egress. A third, 8’ diameter, four-wing, BoonAssist TQ manual revolving door is installed at the employee entrance, thereby eliminating the “stuck door” problem when it was a manual swinging door.

Sinai Health System is comprised of Mount Sinai Hospital, Joseph & Wolf Lebovic Health Complex; Bridgepoint Active Healthcare; Circle of Care; the Lunenfeld-Tanenbaum Research Institute, and is a full affiliate of the University of Toronto.

Boon Edam Inc., a global leader in security entrances and architectural revolving doors. Mount Sinai Hospital in Toronto achieved success in reducing wind tunnel issues within its high-volume, three entrance public corridor into the hospital’s main entrance. Dor-Control Craftsmen, Ltd. installed the entrances and oversees on-going maintenance needs.

The Boon Edam Duotour is a high capacity, automatic revolving door. When an entry needs to channel the flow of visitors in high numbers at peak times, or those accompanied by carts, wheelchairs or hospital gurneys, the Duotour two-wing automatic revolving door is often the solution. Due to the relatively large size of its two compartments compared to 3- or 4-wing doors, the Duotour can channel a high capacity of traffic while having a small footprint.

“We try to monitor the sliding door use as much as possible, but we still have some gusting issues,” said Khouri. The revolving doors are the best solution, given our space and property limitations, and these entrances have cut our wind tunnel effect by 60-70 percent. I believe that the revolving doors are the biggest factor in that improvement. The Boon Edam revolving doors are of good quality, they’re superior to regular doors, and they are helping us achieve our entrance and comfort goals.”
