The Weitzman School of Design Department of Historic Preservation and the Association for Preservation Technology Delaware Valley Chapter (APT-DVC) present a one-day symposium focused on the subject of building resilience, referring to both the structures that demonstrate this quality and the actions needed to ensure it in our built environment. How have so many buildings survived, and thrived, for so long? What can we do to ensure their continued survival and relevance?
Focused on the historic built environment of Philadelphia, we will present a series of speakers, panel discussions, and case studies that will define what we mean by building resilience, particularly as we look to a future with a rapidly changing climate. Presentations will include multiple investigations of resilience, providing attendees with an understanding of the concepts and the tools to carry them forward.
Submitted for AIA Continuing Education credits approval.

The Resilient Enclosure
A diverse panel of practitioners will explore and debate how current sustainability practices and materials may be applied to older buildings, to improve performance without sacrificing their inherent value. Topics will include a broad range of repair and restoration situations and treatment approaches. Moderated by Michael Falstad (RWDI).

Cliveden National Trust
Preservation Director Libbie Hawes will lead a tour at Cliveden, the historic country house of the Chew family. Recent repairs to the original stable building, featured in the last session of the symposium program, will be discussed, along with additional pointing work and paint color identification and selection. Tours of the 1767 house, lived in my seven generations of the Chew family, will be offered as well.
The Wagner Free Institute
The Wagner Free Institute was incorporated in 1855, and the current building completed in 1865. The building, lecture hall, and exhibits are all relatively unchanged from that time. Site manager and APT DVC board member Nic Tenaglia will talk about the challenges of maintaining this National Landmark building. A tour of the museum is included, along with any lectures or presentations that may be taking place. Please note that the Wagner is not wheelchair accessible.
Historic Rowhouses
Lecturer and historian Bruce Laverty will lead a tour of the neighborhoods featured in his Friday morning talk. This will be a walking tour, rain or shine – please dress appropriately.
