Saving the Old to Teach the Young at Penn
Saving the Old to Teach the Young at Penn

On the northeast corner of Walnut and 36th Streets in Philadelphia stands the adaptive reuse and expansion of the historic West Philadelphia Title and Trust Company building from 1925. Now known as the Ronald O. Perelman Center for Political Science and Economics at the University of Pennsylvania, it combines the adaptive reuse of an existing building with a new addition that exemplifies the climate-driven message that the best building is the one you don’t have to build. The team established a scheme to integrate the careful retention, preservation, and reuse of the existing building with a 56,700 sq. ft. addition to create a high-performance academic building. The constraints of the existing building inherited by the design team encouraged a high degree of creativity and collaboration. The project team will discuss the analysis used to determine the most appropriate strategies to avoid demolition and reduce embodied carbon, including preserving the historic building envelope, balancing thermal comfort, and increasing access to natural light, and careful program placement to avoid structural reinforcements. In working within these constraints, the team designed for two distinct conditions with a seamless interior experience that reduces embodied carbon while optimizing energy performance, visual comfort, and thermal comfort. The session will also address how to resolve questions of historic building design by using 3-D laser scan information. In this session, representatives from the University of Pennsylvania, KPMB Architects, Atelier Ten, and Keast + Hood Structural Engineers will shed light on the variety of challenges and opportunities of working with historic buildings and evolving them to adapt to 21st-century academic needs. The client will articulate how this project helps Penn achieve its institutional sustainability goals. The project partners will discuss design, programming, thermal and structural strategies to exceed a client’s initial LEED mandate and minimize the project’s embodied carbon.
