Rising thousands of feet into the sky, these towers may look invincible, but architects must also make them livable.
By Clay Risen
Soaring more than 1,200 feet into the sky, supertall skyscrapers are monuments of engineering prowess, from their structural design to their construction. Less well appreciated is the technology that makes them livable: How exactly do you heat and cool a tower that shoots a half mile into the sky?
In a standard high-rise, it’s mostly a matter of scale: With large enough pumps and heat exchangers, a single system with a cooling tower and chiller plant on the roof can service an entire building. But as a structure approaches supertall status, this one-building, one-system approach becomes too expensive, too inefficient, and too bulky.
“Supertalls are like cities standing vertically,” says Mehdi Jalayerian, an executive vice president for Environmental Systems Design, in Chicago, which consults on HVAC design for supertall towers. “The real challenge is how [do you] get environmental controls and amenities [to residents] as you get higher?”
The answer: Creatively.
