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.

Learning Objectives

• Understand the lime cycle.
• Understand lime materials.
• History and origins of lime use in America.
• Importance of lime use in modern preservation work.

SPECIAL TOPICS

PRACTICAL GEOMETRY: Framing With a Compass
Jane Griswold Radocchia

Come draw! See how Serlio, Palladio, James Gibbs and William Buckland used Practical Geometry. This session will teach about the geometry of historic frames erected in the rural Northeast and compare that geometry with what was used in Virginia, Maryland, and Louisiana. Attendees will practice proportioning a steeple, plan a glass curtain wall without numbers, and generate a complete timber frame from one dimension and one length. This can all be done through the use of daisy wheels, the rule of thirds, the 3/4/5 rectangle for construction and design. You will wonder why they no longer teach this in high school. Compasses, straight edges, and paper will be provided. Bring a pencil!

Learning Objectives
