Historic places around the globe are increasingly being impacted by flooding and rising sea levels caused by climate change.  As a result, preservation professionals are being asked by historic building owners/stewards for technical guidance to protect a wide range of historic buildings dealing with an even wider range of environmental circumstances. This symposium follows a case study format to illustrate a number of “hardening” interventions at the building level, but also at some landscape level approaches. Each case study will discuss the project’s historic and environmental context, the technical intervention, an assessment of the success, and most importantly lessons learned. At the end of the morning session, participants will understand how increased instances of flooding/sea level change are impacting historic buildings; understand current code and regulations relating to flood design; be able to discuss advantages and disadvantages of a variety of approaches and be able to assess technical treatment alternatives to best meet preservation and resiliency goals. The afternoon will include a walking tour that highlights local flood control efforts followed by an interactive discussion with the entire panel and the audience discussing how APT can help NCPTT and the larger preservation community by developing technical guidance for protecting historic buildings against rising waters.

Over the course of 2 days, this workshop will use the carved stonework at Mission San José and its sister missions as a classroom for identifying the modes of deterioration that affect sedimentary stones and for studying a variety of conservation and restoration approaches. A strong emphasis will be placed on using reversible treatments for the repair of different forms of stone loss, cracking and delamination. Time tested traditional stone repair techniques dating from before the development of synthetic resin adhesives, as well as techniques that utilize modern materials, will be demonstrated. The participants will have the opportunity to try out a variety of reversible stone repair techniques that are applicable to the conservation and restoration of limestone and sandstone and, in some cases, marble. The workshop will be led by two conservators who have several decades of hands-on experience conserving stone buildings and monuments.

A Two-Day Workshop produced by the APT Technical Committees on Preservation Engineering and Sustainable Preservation, this workshop will examine principles for practice, including recent developments in building envelope science, for the documentation, performance modeling, and assessment of historic building envelope materials and construction, including addressing design of mechanical enhancements for buildings in both hot and cold climate zones. The workshop will include:

  •        thorough discussion of moisture movement in building envelopes;
  •        an overview of the newly-published ASHRAE Guide for Historic Structures;
  •        how new mechanical, electrical, and plumbing systems and new/existing integrated hybrid designs,
           more harmonious with heritage character, are meeting higher sustainability needs;
  •        case studies that illustrate specific technical challenges and ways and means for overcoming them;
  •        a field session that will bring participants into contact with hands-on examples.

Presenters will inform preservation architects, engineers, and conservators on best practices regarding “whole building ecologies” and the balance that must be achieved between historic buildings, their envelopes, and the upgrades and energy efficient systems supporting their continued use and stewardship as cultural resources.

The Workshop will include a tour of The Alamo and The Milam Building.
