PHILADELPHIA, PA–Penn Medicine University City has agreed to expand into an additional 56,000 square feet or two entire floors at the recently opened 3737 Science Center Building. With this lease expansion, the anchor tenant will occupy 267,800 square feet in the 13-story laboratory and office building at 3737 Market Street in Philadelphia.

This 56,000 square foot expansion means that the 334,000 square foot building is now 100 percent leased. Penn Medicine has relocated its Orthopedics Outpatient Program and other groups to the 3737 Science Center location, and will be using the additional two floors for medical offices.

“3737 Market's rapid lease up exemplifies the attractiveness of the Science Center as a location of choice for organizations in the innovation ecosystem,” says Science Center president and CEO Stephen S. Tang, Ph.D., MBA. “Penn Medicine University City is a valuable partner of the Science Center and we are delighted that we could accommodate their expansion needs.”

Wexford Science + Technology, which designed the center, notes that 3737 Science Center has achieved LEED Gold certification for its core and shell design. The building includes several unique design features focused on energy efficiency. For example, it is the first health care building in Pennsylvania to have a chilled beam system -- an advanced convection HVAC system designed to heat or cool large buildings.

Wexford and the Science Center implemented an extensive green roof system with a “white roof” membrane that more efficiently manages the challenging seasonal weather of Philadelphia while helping the building achieve the Heat Island Effect credit by reducing heat emissions from the building. The building also implemented a storm water management strategy to efficiently handle storm rain without overburdening the city's sewer system.

“We are proud that our 3737 Science Center building has received the prestigious LEED Gold certification because we understand that importance of providing the most energy efficient environment for tenants, such as Penn Medicine University City, which need 24/7 uptime,” says Joseph Reagan, vice president of development for Wexford Science + Technology. “We are excited that our plan to use innovative design solutions such as the chilled beam system is seen as a benefit to our tenants, the West Philadelphia community and our environment.”

Developed jointly by Wexford and the Science Center, 3737 Science Center provides approximately 334,000 square feet of premier laboratory and office space at the epicenter of Philadelphia's renowned "eds and meds" community that is home to the University of Pennsylvania and Drexel University, as well as The University of Pennsylvania Health System, The Children's Hospital of Philadelphia, University of the Sciences and The Wistar Institute.

In addition to Penn Medicine University City, a facility of Penn Presbyterian Medical Center, tenants of 3737 Science Center include Spark Therapeutics, a cutting-edge gene therapy start-up that spun out of The Children's Hospital of Philadelphia; Good Shepherd Penn Partners, which operates the Penn Institute for Rehabilitation Medicine; and The Rose Group, owner of the Corner Bakery Café, which is expected to begin service on the ground floor of 3737 Market Street on March 25, 2015.
