The Architectural Conservation Laboratory is a facility of the Department of Historic Preservation/Weitzman School of Designopen_in_new dedicated to the examination, analysis, and treatment of historic and traditional architectural materials and the building arts. Founded in 1991, the laboratory serves as a graduate training and research center, providing the necessary technical support for the department’s conservation curriculum and advanced research in architectural conservation.
Leadership
The ACL is led by Professor Frank Matero open_in_new, who founded the lab upon his arrival at Penn in 1991 to provide the necessary scientific facilities for teaching the then newly launched curriculum in the technical conservation of the built environment.

Training the next leaders in conservation
Since 1991, both the field and Penn’s role in educating its leaders has greatly expanded through innovative approaches to documentation, recording, field survey, material analysis, condition assessment, and treatment evaluation of historic structures and sites.

Cutting-edge equipment
The dedicated space and equipment support the program’s specialized courses in building conservation science and its seminars in masonry, wood, concrete, finishes, and other architectural materials and systems. It also provides a technical support facility for the Program’s Center for Architectural Conservation.
A materials-based approach
The ACL supports materials-based inquiry through courses and research dedicated to the study of historic and traditional building materials and construction systems including their characterization, diagnosis, and treatment, both remedial and preventive.
The ACL also houses the historic 19th-century plasterwork collection from the Alhambra, as well as the Vermont Marble Company’s international archives and stone library and the Walker Zanger commercial stone library, two of the largest US commercial global stone collections.
