Case study
Airlock lobbies against the wind, on the roofs of the QatarEnergy towers
At the top of a tower, opening a roof door can let the wind in with force. We did the structural design for airlock lobbies on the roofs of the QatarEnergy towers, so that the wind stays out when the door opens.
Why wind was a problem at roof level
The roofs of these towers are very high, and high winds made it a problem whenever the roof doors were opened.
What we did
We did the structural design for an airlock lobby at roof level: an enclosed space between the tower and the open roof.
The design covered multiple towers, working with Hanson International and Al Balagh Trading and Contracting.
What the client received
- Airlock lobby structural design report, with the analysis and connection design
- Structural drawings for the towers
We have also designed an airlock lobby with Hanson International for a second client in Qatar, whose tower faced the same problem.
If your tower has the same problem
An airlock lobby is added to a finished building, so the structure has to resist wind at height and fix safely to a roof that is already in use. Send us the existing roof drawings and the lobby layout, and we will tell you what the design needs.
