The project
Serving 70 million passengers a year,
Chicago’s O’Hare International Airport is
one of the busiest airports in the world –
and with seven runways and a total of
178 gates one of the largest. It is one of
the most important transportation nodes
in North America and a main hub for many
international airlines. As the Assistant
Chief Operating Engineer for the City of
Chicago’s Department of Aviation, Dominic
Henry is responsible for building automa-
tion and hence the interaction of heating,
ventilation and air conditioning (HVAC),
building security and fire safety – no easy
task.
At O’Hare International Airport
in Chicago, an integrated building
management system based on
Desigo CC™ ensures optimal
visitor comfort – along with
maximum energy efficiency.
The challenge
Travelers at the airport have a lot on their
minds: “What is my gate again? Where
did I put my passport?” With a passenger
volume like that of O’Hare, it is nothing
short of a miracle that travelers don’t
need to ask why it is so hot and sticky.
Because it isn‘t, thanks to intelligent
building automation. Terminal 3’s com-
plex HVAC infrastructure, a blend of dif-
ferent building automation systems from
a variety of manufacturers, needed to be
integrated into a uniform system to ensure
maximum building comfort and minimal
energy costs.
