    Building Science and Preservation Workshop 

    New Approaches and Technologies to address Challenges in Rehabilitating Historic Structures

    Join renowned and widely respected building scientist William Rose as we spend two packed days that show building science at work in preservation. This workshop will provide a solid base in physical science-fluid flow, water vapor, radiation and heat flow. Learn some approaches to hygrothermal modeling and how to apply it. (Quick but intense). 

    The workshop will continue as we will tackle juicier questions in preservation such as freeze-thaw, condensation, and adoption of energy efficiency measures in existing buildings. It will address how to monitor buildings, and how to use monitored data to help make important building decisions. The focus will be on walls (particularly masonry walls), foundations, and attics/roof systems.

    The workshop will showcase several case studies of building science in use in preservation.

    The author of a landmark book, Water in Buildings, William Rose is a research architect at the University of Illinois at Urbana-Champaign and a widely respected building scientist.  Hear Bill lead the workshop and he sets the stage for enabling the attendee to make solid judgments regarding energy-saving measures and consequent performance in existing buildings. Understand how to make hygrothermal analysis of building walls, attics and foundations using one's own calculations.  And finally, participate in case studies that bring the theoretical into practice.

    Preservation of Fire-Damaged Platteville Limestone

    at the Mill City Museum 

    We welcome you to join us on June 11th where Angela Wolf Scott from MacDonald and Mack Architects will present the current preservation work at the Mill City Museum that focuses on the technical aspects of analysis and treatment of fire-damaged limestone ruins.

    The Washburn Crosby A Mill Complex is a National Historic Landmark on the Mississippi River in downtown Minneapolis. It was the epicenter of flour milling and innovation from the late part of the nineteenth century until 1965 when the site was no longer used for milling. The site suffered from multiple fires, but the February 1991 fire left the A Mill in a fragile state of ruins.  In 1999 the site was redeveloped into commercial office space and the Mill City Museum.  The most iconic part of the redevelopment is the Ruins Courtyard – a space that had been the southern half of the A Mill which is currently open-air and bound on three sides by the Platteville limestone ruins of the A Mill.

    To improve their stewardship of the Washburn Crosby A Mill Complex, MNHS commissioned a Historic Structure Report on the complex with a key concern being a study of the ruins. Pieces of stone and mortar were routinely falling into the much-loved courtyard. The HSR included analyses of the characteristics of Platteville limestone in general but focused on the specific characteristics of the Platteville limestone of the ruins which had been exposed to fire; dramatic, thermal shifts; exposure to the elements; and modern, restoration products.

    Armed with a more precise understanding of the physical properties of the stone and ruin walls, MNHS invested in the preservation of the ruins, approaching the work in phases. The physical preservation work uncovered and confirmed the academic research and analysis, making each subsequent phase more informed than the last.
