Exceeding expectation.
Delivering 20 percent more on a challenging site.
Overachieving, on brand.
Boston’s “Technology Corridor,” arguably the second largest tech hub behind Silicon Valley, was the site of this mission critical colocation facility. Digital Realty was looking to build with the goal to fit four data halls on the tight suburban site, the steep terrain and small land parcel for the square feet of proposed development made this a unique project, which posed opportunities for creatively approaching the planning process.

HED performed architectural and engineering services to design a three-story facility, with a focus on maximizing use of the site. Through clever planning, the design allowed accommodation of five 10,000 SF data centers, a 20 percent increase over the original expectation.

The design features an interior shaft devised to exhaust waste heat from the five data halls and from the interior generator plant on the lowest floor. Exhaust and supply separation enables utilization of outside air when temperatures permit, boosting the project’s LEED certification to Gold. Due to the site size, innovative approaches were used to incorporate all MEP components into the building or onto the roof as opposed to in a yard. Contextual brick, ribbon windows, and a glass curtain wall support the client’s exterior design aesthetic and reflect the context of the surrounding neighborhood.
Results
The new facility contains five 10,000 SF data centers, exceeding the original expectation of only accommodating four, resulting in the project's increased ROI for the client.
Built on a greenfield site, the 123,000 SF facility is LEED Gold certified.
Outside air economization boosts the facility's sustainability and saves the client on yearly energy costs.
Total IT Capacity: 5.6MW
Tier III, Concurrently Maintainable Data Center
On a suburban site, the structure fits the landscape, blending in with neighboring buildings with all systems contained within the shell of the building and hidden on the roof.
Our knowledge of the business case and the spatial and MEP requirements for this repeat client enabled us to work with them to maximize the return on their investment through careful planning from the inception of design.”
