KEYNOTE

CIRCLE BACK: Preservation Trades in a Circular Economy
Mae Bowley

Deconstruction is a perfect example of a nearly lost trade reemerging to meet the needs of the growing circular economy. We will explore the history of deconstruction, its decline, and its return to prominence as a sustainable alternative to demolition. We will discuss the relevance of deconstruction and reuse for all other historic trades and the interdependence of traditional craft and historic salvage. Finally, we will engage in conversation about the potential for traditional craftspeople to help address contemporary issues that intersect with preservation, such as affordable housing and climate change, through collaboration.

I'LL QUICK YOUR LIME
Jason Whitehead

Lime remains one of the most valuable building materials in human history. Its origin in human construction likely predates recorded history, but it’s at least 8,000-10,000 years ago. From the earliest days of colonization in the present-day United States, settlers used this tradition of lime to build new villages, buildings, and cities. At the same time, in western America, Hispanic culture incorporated lime in construction in areas of what are now Texas and New Mexico. The idea of lime is simple. The material for production is plentiful and comes in many forms depending on geology. During this demonstration we will be burning oyster shells, a local and plentiful resource, in order to convert the calcium carbonate into quicklime for building.

  • Understand the lime cycle.
  • Understand lime materials.

Then, with no numbers, lay out a dwelling from 17th century Virginia, a pediment ala Vignola, a dome like that of Hagia Sophia. Use Lines and the Rule of Thirds for layout and design, as did Palladio and Serlio. Bring a pencil.
