"From Grime to Sublime: Standards for Cleaning Masonry Buildings"
2nd AIA Taliesin West Colloquium
Taliesin West
October 10-12, 2014

    **** Moderator's comments: For further details see original
    announcement in Conservation DistList Instance: 28:4 Tuesday,
    July 1, 2014

Sponsored by the AIA Historic Resources Committee, the Frank Lloyd
Wright Foundation, and the Architectural Specialty Group of the
American Institute for Conservation of Historic and Artistic Works

The maintenance, repair, and rehabilitation of existing buildings
often includes cleaning the exterior surfaces of stone, brick, terra
cotta, and concrete.  There are philosophical, aesthetic, technical,
scientific, and economic factors that should be considered when
specifying materials and methods for cleaning.  What is the masonry
material, and what is the cause and composition of soil?  Is the
soiling damaging the masonry material?  What are the owner's
expectations?  What is an appropriate aesthetic target for the
character of the building?  Is the patina character-defining?  Will
a particular cleaning approach result in short term appeal and long
term damage?  Is the masonry best left alone?  What is an optimum
cycle for recleaning that balances the applicable factors?  In
summary, how do we characterize soiling, how should one clean a
building, and ought one to clean a building, and what is the meaning
of 'clean'?

The program will open with an outdoor desert terrace reception
followed by the keynote lecture on Friday evening, October 10, 2014,
and an evening tour of Taliesin West by staff, faculty, and
students.  The core of the program consists of presentations and
discussion with the speakers on Saturday morning, October 11, 2014.
After a box lunch, attendees will meet in topical Saturday afternoon
breakout sessions for discussion and demonstrations, and report back
in assembly to close the day.  On Sunday, October 12, 2014 Richard
Wolbers will present an optional all-day advanced workshop.
