Skidmore, Owings & Merrill is revisiting one of its seminal projects of the 1950s, the Inland Steel Building. The firm has been asked to renovate the Chicago landmark into an office hotel, a building type that offers potential tenants a sustainable and fully outfitted office space while still allowing for flexibility in office layout, size, and lease duration. That means a ground-up renovation to meet contemporary standards of sustainability, as well as the out fitting of spaces with flexible systems to allow for the reconfiguration of space for each “guest.”
Because of the building's landmark status, certain of SOM's proposed improvements—like a planned double-glazed curtain wall—cannot be implemented. But there are other, permissible strategies that will improve the building's performance, such as chilled beams, which use less energy for cooling than conventional HVAC systems. The architects have developed a system of modular partitions with spring-loaded connectors that take advantage of the existing column-free space. SOM also designed a catalog of furniture that guests can choose from; all pieces fit the building's 1950s aesthetic while conforming to modern sustainable standards for VOCs and formaldehyde.
The jury was taken with the commitment to finding new methods, and overcoming challenges, in an effort to make a mid-century building sustainable by today's standards. “The fact that this is land-marked actually created huge limitations on the retrofit,” said Blaine Brownell. “It couldn't be double-glazed, which probably would have been much better, so there's all kinds of attention being paid to these minor environmental upgrades— with, I'm sure, significant cost as a result. Ultimately, it shows that there's a [larger] problem: Are we being serious about upgrading these buildings?” Andres Lepik appreciated the attention to detail: “You take a land-marked tower and make a sustainable restoration, down to the desks and the chairs.”
