“Brookfield took the approach that we wanted to be able to cater to data center tenants,” Stifelman says. “We’re looking for people who require standard and above-standard power and cooling.”

Among the improvements at the complex are $23 million of additional transformers and other energy infrastructure, including boosting in-load capacity with redundant capabilities that involved replacing and expanding switching gears and generators, and expanding transmission capacity. The improvements were completed over a year ago.

“We have the power, the backup power and the redundancy so that if there is a failure you will still have power coming in,” says Michelle Berliner, VP and head of asset management at Brookfield. The developer acquired Convergence from JP Morgan Chase, which remains a tenant, in early 2010, following the completion of the power upgrade.

The complex has a history of being home to the highest levels of corporate technology. Developed by International Telephone and Telegraph in the 1950s, Convergence’s first building housed the switching equipment for the famous “Red Phone,” the hotline that provided secure communication between the White House and the Kremlin during the Cold War. But more was needed.

The site also has enough space and capacity for a 200,000-square-foot build-to-suit data center, Berliner said. The project is ready for immediate build-out as tenants sign, Stifelman says. “Brookfield has been one of the greatest landlords I’ve worked with,” he says. “This has been a great project.”
